Section 2. Installation and Strapping of Boards

Appendix A. Data Hiway Installation and Termination

Siemens Applied Automation, Inc. provides this manual primarily for those customers who want to installcircuit boards in a chromatograph of I/O unit. The information presented in this manual is intended to helpskilled workers make better decisions about how to install the equipment. It is assumed that the workersinvolved (instrument technicians, mechanical technicians, electricians) have a good working knowledge oftheir respective trades and are experienced in the installation of similar equipment.

This manual cannot cover all problems that could arise or procedures for installing circuit boards in everyunique set of circumstances. Instead it offers a practical and expedient approach to performing the installa-tion tasks normally required.

Other Documentation

This manual covers hardware installation only. Since most boards require software, the Application Modifica-tion Manual (2000517-001) will be needed to make the changes to the application table set when an addi-tional board is installed.

Should board operational problems arise, refer to the system Maintenance Manual (2000530-001).

Additional information about policies, field services, contract maintenance support, spare parts, repair serv-ice, educational support services and other customer services offered by Siemens Applied Automation, Inc.can be found in the Directory of Customer Services.

When to Use a Guide on the Board 5

This section provides a method of selecting board addresses and locations. Standard addresses and loca-tions are intended to give the user a guide while performing the installation procedures of Section 2. The in-formation here is only a suggestion, and specific applications may dictate modifications.

What is a System Address

A system address is a numerical identifier whose individual parts pertain to the loop, unit, slot and channelof the communications network. For devices which connect directly to the data hiway, only the loop and unitare used. For I/O boards which do not connect directly to the hiway, all four are used. Devices for which onlyloop and unit addresses are used are:

• Analyzer• Input/Output Unit (IOU)• Printer Interface (PI)• Applications Personal Computer Interface (APCI)• HOST Computer Interfaces (HCI)• Advance Interface for Chromatographs (AVI)

The loop number is the identifying number of the Data Hiway to which a particular unit is connected. Up toeight Data Hiways can be connected into a single system. Loop numbers are assigned in order, from 1 to 8.Each loop can contain units numbered from 1 to 31.

The unit number is the identifying number of a particular unit on the loop. It is a unique number, from 1 to 31,which distinguishes each unit from others connected to the same loop. The unit number determines thecommunication priority for the unit, with line access priority highest for Unit 1 and descending in order toUnit 31.

The analyzer and I/O unit each contain slots for plug-in boards. Each slot can hold one I/O board which con-tains several predefined channels of I/O. Only the loop and unit numbers are selectable on the analyzer andI/O unit. The slot number is determined by the physical location of the board in the chassis and channelnumbers are predetermined by the board electronics. The Printer Interface (PI) and the HOST Computer In-terface (HCI) are exceptions since they are physically connected to the Data Hiway as well as residing inI/O board slots. The PI and HCI have selectable loop and unit numbers independent of the analyzer or theI/O unit where they are located.

3

How to Select an Address for Hiway Devices

You may select an address for each unit in your specific equipment configuration by referring to Table1-1. The system operates properly with any unit and loop assignments, but those of Table 1-1 are recom-mended to standardize the programming and operation. If more unit numbers are needed than are assignedto a given category in the table any unused numbers may be used. Unit numbers need not be consecutive,but duplicate numbers are not allowed.

When more than 31 units are needed in a single system, additional loops can be added. Since additionalloops require additional hardware (HNET High Speed Network Interface Unit) to interconnect them, they arenormally used only when more than 31 units are needed or the interconnect distance is more than 5000 ft(1520 m).

Analyzer numbers are independent of the system address. However; normally, the analyzer number is thesame as the unit number, at least for the first 20 analyzers.

Table 1-1. Standard Single-Loop Unit Number Assignments

LOOP UNIT DESCRIPTION

1 1-20 Analyzers (assigned consecutively from 1)

1 21-24 I/O units (assigned consecutively from 21)

1 26-30 Printer Interfaces (assigned consecutively from 26)

1 30-26 HOST Computer Interfaces (assigned in descending order from30)

1 31 Application Personal Computer Interface

How to Select the Slot for I/O Boards

Standard board slots are listed in Table 1-2 for boards installed in the analyzer backplane. Although anyboard will operate in any slot, it is recommended that standard slots be used when practical for consistencyand ease of maintenance. Slots are numbered from left to right. Note that slot 1 does not exist on the ana-lyzer backplane. The Analyzer Termination Board, installed on the left side of the analyzer electronics en-closure, is addressed as slot 1.

Except for the Input/Output Unit Interface (IOUI) which is normally installed in Slot 1, there are no standardslots for the Input/Output Unit (IOU). If a board is to be installed in the I/O Unit select the lowest numbered(left most) available slot and install the board there.

When to Use a Guide on the Board

If the board is to be installed in an analyzer board slot, then a guide must be attached to the top edge of theBoard (see Figure 1-1). If the board is to be installed in an Input/Output Unit slot, then the guide must beremoved from the board.

Analyzer Controller Door Assembly (2000400-006)Analyzer Controller Board (ACB2) (2000212-001)

The Analyzer Controller Door Assembly (ACDA) is the electronic control portion of the OPTICHROMADVANCE process chromatograph system. The ACB2 Analyzer Controller Board (Siemens Applied Auto-mation, Inc. Part No. 2000212). To access the Board for strapping LOOP and UNIT numbers, the perforatedscreen must be removed. Refer to Figure 2-6.

The UNIT (S2) and LOOP (S3) switches are located in the upper left-side of the ACB2 Board. Refer to Figure2-7. These switches are binary weighted and are used to set the device address. This allows a device tocommunicate, with other devices connected to the Data Hiway.

Analyzer Controller Door Assembly (2000400-006) (Continued)

There are four LEDs visible through the front of the door. They are marked, from top to bottom; PURGE,FAULT, WARNING and NORMAL. At the start of the self-test sequence, all four LEDs should flash “ON” forapproximately one second. Only when both the red FAULT and yellow WARNING LEDs are “ON” has theself-test failed (if all LEDs were initially “ON”). If the FAULT LED is on and the WARNING LED is blinking,then the Controller Assembly has not been installed properly or the ACB2 is defective. The WARNING LEDblinks the error code and then if “OFF” for about five seconds. The number of blinks of the WARNING LED isthe error number. Table 2-1 lists the number of blinks, the type of error and corrective action to be taken.

After the self-test, normal operating conditions will cause the NORMAL LED to light. If the PURGE LED con-tinues to flash after the analyzer door is closed and the enclosure purged, refer to the System MaintenanceManual (2000530-001). If the system has an alarm condition, then either the WARNING or FAULT LEDs willbe “ON”, but not both. This condition should be corrected as per the System Maintenance Manual instruc-tions.

How to Set ACB2 Unit and Loop Switches

How to Set Switches

To set LOOP and UNIT switches perform the following procedures. The LOOP and UNIT switches are lo-cated in the left-side of the ACB2 Board. Refer to Figure 2-7.

Step Action

1. Turn Device primary AC power OFF.

2. Open the EC door to expose the ACB2 mounted ACB2 Board shield. The ACB2 Board ismounted behind the shield.

3. Loosen and remove the screws that hold the shield in place. Remove the shield.

CAUTION

Do not allow the shield mounting screws to fall onto any electronic components. A short circuit could occurwhen Device primary AC power is applied which would damage or destroy components.

4. The UNIT and LOOP switch banks have five (5) individual switches, each having a specific bi-nary weighted value for determining the Device address and Service Panel keyboard lockout.The first UNIT switch (#1) has a value of one or zero. The second switch (#2) has a value of twoor zero. The third switch (#3) has a value of four or zero. The fourth (#4) has a value of eight orzero. The fifth switch (#5) has a value of 16 or zero; see Figure below.

All LOOP switches function the same as the UNIT switches except that only four switches areused in selecting the Device loop address. The fifth switch is not used.

17

How to Set ACB2 Unit and Loop Switches (Continued)

Step Action

5. Valid loop numbers are from one (1) to eight (8) and valid unit numbers are from one (1) to 31.

6. Setting LOOP and UNIT switches to zero (0) and cycling Device power will clear the currentdata base.

7. After clearing the data base, set the LOOP and UNIT switches to valid address settings. Aftersetting the address, turn Device primary AC power ON.

18

ACB2 Board Jumper Settings

The ACB2 board which is located in the EC Enclosure door has six jumper connections which are factoryset to the settings shown in the Table below.

JP1 (Spare Input)JP2 (Balance Enable)JP3 (Chart Driver)JP4 (EPROM)JP5 (Battery Backup)JP6 (1/4 MEG RAM)

CAUTION

After repair or removal of the ACB2 Board and before power is applied verify that all six jumpers are set tothe normal position. The white marks show the correct jumper placement. Refer to Figure 2-8.

Using the ITC as a Spare Input

If the ITC detector is not needed, its circuitry may be configured as a third spare input. To do this, changeJumper JP1 to the non-default position (see “Setting Jumpers”). If desired, the ITC balance command can beused to balance the output of this spare input, but typically, the balance for a spare input takes place beforethe signal reaches the ACB. If the signal is balanced before reaching the ACB2, the Balance Enable jumpermust be moved to the non-default position which will disable the ITC balance.

To connect a spare input:

• ITC+ is not used.

• Connect ITC- to the signal wire (positive)

• Connect the ground reference signal wire (negative) to the Spare Input GND pin on the ATB (pin 20).

It is unfortunate, but the way the circuitry must be wired puts the positive signal of the spare input on theterminal labeled ITC-. This will be a point of confusion, but could not be avoided without creating more confu-sion somewhere else.

This input must be driven by a low-impedance output. The input impedance is 200 Kohms.

Just as with the other spare inputs, gain is one, and the signal is filtered by a 15 Hz low-pass filter beforebeing digitized.

21

Analyzer Termination Board (2000102-001)

The Analyzer Termination Board (ATB) (Figure 2-9) is installed on the left wall, inside the analyzer electron-ics enclosure.

Figure 2-9. Analyzer Termination Board (2000102-001)

Options Available

• The ATB is primarily a terminal board to connect the Analyzer Controller Board to the rest of the ana-lyzer hardware. The options available, therefore, depend on the analyzer hardware. Several available op-tions will be apparent from the wiring installation instructions of Steps 5 through 9.

22

Analyzer Termination Board (2000102-001) (Continued)



2. Install the ATB on the left wall, inside the analyzer electronics enclosure with six 6-32 x 3/8 longscrews.

3. Orient the Relay Board (2000103-001) so that plugs J9, J10 and J11 of the Relay Board are lined up withsockets J9, J10 and J11 on the ATB and plug it into the ATB. Fasten the Relay Board in place with four6-32 hex nuts.

4. Connect the 1/8 inch clear plastic tube (on the 1/16 inch tube union through the back of the electronicsenclosure) to the hose bib on the purge switch SW1.

5. Connect the wiring to ATB terminal strip T1 at the bottom right edge of the board. Refer to Figure2-10 if the AC power source is 120 volts and Figure 2-11 if the ACB power is 240 volts (a 240 volt to 120volt stepdown transformer is required for the 240 volt source). Number 18 AWG wire or larger should beused except for the AC POWER IN wires which should be number 12 AWG. The fan and temperaturecontrol relays are located inside the electronics enclosure on the right wall (RY1 is the relay nearest thefront). The Analyzer Master Board (AMB) is on the back wall.

Connect the heater air pressure switch (at the back near the bottom of the right wall of the electronicsenclosure) (terminals 16 and 27).

If a Flame Ionization Detector (FID) is installed in the analyzer, connect the detector signals to AnalogInput Channels 10 and 11. Connect the FID signal high (FID terminal 18) to AI channel 10 (ATB terminal21), ITC signal high (FID terminal 17) to AI channel 11 (ATB terminal 22) and FID/ITC signal low (FIDterminal 16) to AI ground (ATB terminal 20). If an FID is not used, Channels 10 and 11 are available asgeneral purpose single ended -10 to +10 VDC analog inputs.

If a Thermistor Detector (TC) is installed in the analyzer, connect the sense, reference and ITC thermis-tor beads as shown in Figure 2-13. If not, make no connections to ATB terminals 12, 13, 14, 15, 18 and19.

A zero to 20 ma Chart Recorder may be connected to ATB terminals 10 and 11. If a voltage recorder isrequired, a suitable resistor must be placed across these terminals. Recorders with full scale rangesfrom 10 mv to 10 volts may be used. If the recorder is to be operated in the Bar Graph mode, connectthe chart drive (through a relay or solid state device to +5V, terminal 1) to the chart drive relay driver(CDR) output, terminal 8.

An external alarm, under software control, may be connected (through a relay or solid state device to+5V, terminal 1) to the alarm relay driver (EXT ALM) output, terminal 9.

Four Digital Inputs may be connected to Channels 30 through 33, terminals 4 through 7. These may beeither contacts to GND (terminals 2 and 3) or 5 volt logic levels.

• The DI board contains eight digital input channels that may be connected in three ways. 1) A contactclosure, powered by an internal power supply may be sensed (Figure 2-18). 2) A contact closure pow-ered by an external power supply may be sensed (Figure 2-19). 3) A logic level signal powered by anexternal power supply may be sensed (Figure 2-20).

2. Select a board slot and insert the DI Board in either the analyzer or I/O unit (refer to pages 4 and 5).Push the board securely into the connector.

3. Connect your field wiring to the Field Wiring Terminals (Figure 2-17). Refer to Figures 2-18 through2-20 for recommended wiring options. Recommended wire is number 22 AWG, or larger, twisted pairs.

If the DI board is to sense contact closures, you have the options of using the internal power supply (onthe DO board) or an external power supply. Making use of the internal power supply is the simplestleast expensive choice. When isolation is required, due to excessive noise or grounding problems, anexternal power supply must be used. Figure 2-18 shows the recommended wiring when using the inter-nal power supply and Figure 2-19 shows the recommended wiring when using an external power supply.

The DO board is also capable of operating with logic level inputs. This option is inherently isolated, us-ing the power supply of the external logic device. Figure 2-20 shows the recommended wiring for this op-tion. Although the figure shows inverting buffers, the input is independent of the type of logic input. Anydevice capable of sinking 0.5 ma to ground will activate the input.

HOST Computer Interface (2000130-002)

The HOST Computer Interface (HCI) (Figure 2-27) may be installed in either an analyzer or an I/O unit. TheHCI must be strapped for loop and unit numbers since it connects directly to the Data Hiway. It is, therefore,independent of the address of the analyzer or the I/O unit in which it resides. The Data Hiway must be con-nected to the field terminals for the slot in which the HCI is installed as shown in the interconnect wiringdrawings.

Figure 2-27. The HOST Computer Interface (2000130-002)

Options Available

• Loop and unit strapping to select the desired loop and unit numbers (see pages 2 and 3).

• Baud rate strapping to select the baud rate. Baud rates of 110 to 9600 are available (4800 baud is themaximum for current loop).

• Serial output of either RS-232C, 20 mA current loop or logic level signals are available. Selection of cur-rent source and output isolation is required with the current loop and logic level outputs.

• Serial format of data bits, parity and stop bits are available on boards with PROM revision level 4.1 orabove.

HOST Computer Interface (2000130-002) (Continued)

Installation Procedures

1. Set the loop and unit straps, if not already set correctly for your system (factory set at Loop 1, Unit 30).Refer to “How to Select a System Address” (page 2) for further information. The loop number is set inthe DIP switch labeled U27 (at grid location 7B), and the unit number is set in the DIP switch labeledU26 (7B). The strapping method is shown in Figure 2-28, and is a binary entry of the number selected.All DIP switches are outlined in Figure 2-27.

Figure 2-28. Loop and Unit Strapping for the HCI

2. Set the baud rate in DIP switch U10 (4B), if not already set correctly for your system (factory set at9600 baud). Figure 2-29 illustrates the method of setting each of the available baud rates. The baud ratemust be set to match that of the device being attached to the HCI. The serial data format is 7 bits, evenparity, 1 start bit, 2 stop bits. The maximum baud rate for current loop is 4800.

Figure 2-29. Baud Rate Strapping for the HCI

41


3. Select either an RS-232C output, a 20 mA current output or a logic level output with the programmingplug (factory set for RS-232C). The plug (see Figure 2-27) is inserted into U2 (2F) for RS-232C output orinto U1 (2G) for 20 mA current loop and logic level outputs. The plug is symmetrical, and may be in-stalled two ways. For normal operation, install pin 1 of the plug to match pin 1 of the socket. Whenpower is applied, the red “TST” LED will be “ON” if installed incorrectly (in the test mode).

4. If a 20 mA current loop or logic level was selected in Step 3, select current source and isolation (if not,skip this step). Current source and isolation selections are made with switches 1 and 2 of DIP switchU14 (4C). (Refer to Figure 2-30.)

5. Boards with PROM 4.1 Revision level (refer to Figure 2-27) or above can be set to another serial formatother than the factory set of 7 data bits, odd parity and 1 stop. (Refer to Figure 2-31).

6. Set the equipment power switch to the “OFF” position before attempting the following wiring or installa-tion procedures.

7. Select the board slot and insert the HCI Board in the analyzer or I/O unit (refer to pages 4 and 5). Pushthe board securely into the connector.

8. Install the field wiring for the data hiway (the serial line wiring is described in 8. Below). HCI field wiringterminals 1 through 6 are wired in this step (all field wiring terminals are identified in Figure 2-39).

If the HCI board is in the analyzer, interconnect the HCI field terminals with the Analyzer TerminationBoard (ATB) terminals as shown in Figure 2-32. Note: The proper ATB terminals are on terminal strip T5on the right edge of the ATB board, NOT terminal strip T4 on the top edge of the board. Unshielded wiresize 22 AWG or larger may be used inside the analyzer. Route these wires away from nearby powerwires.

Figure 2-32. HCI Data Hiway Wiring to ATB

If the HCI board is in the I/O unit, interconnect the HCI field terminals with the I/O Unit Interface Board(IOUI) terminals as shown in Figure 2-33 (the IOUI is normally in slot 1). Recommended wiring is Belden9182 cable (1686002-001) or equivalent. Wire one cable for each channel. Ground the shield at one endonly (grounding to the IOUI is recommended in the I/O unit).

10. Set the equipment power switch to the “ON” position. If no red LED remains “ON” after 30 seconds, theboard is operational and the installation is complete. The next paragraph explains the LED codes andfailure modes.

The HCI will perform a self-test sequence on power-up, which may be reactivated by pressing the push-button “RST” switch, SW1 (at grid location 10E). The eight center LEDs (two red, one yellow, and fivegreen) should all flash “ON” for approximately one second, and then go “OFF” in the normal self-test se-quence. After the self-test, normal operating conditions will cause some of the green LEDs to flash. Ifany of the red LEDs remain “ON” after the self-test sequence, or if a yellow LED continues to blink, thenthe board has not been installed properly, or the board is defective (see Table 2-3 for LED error code ex-planations). After the yellow LED blinks the error code, it will stay off about five seconds before repeat-ing the sequence.

The green LEDs indicate the operational status; GS1 = DH RECV; GS2 = DH XMIT; GS3 = HOSTRECV; GS4 = HOST XMIT; GS5 = DH B ACTIVITY.

I/O Unit Interface (2000126-001)

The I/O Unit Interface (IOUI) (Figure 2-47) interfaces the Data Hiway with the I/O unit thus allowing otherequipment on the hiway to communicate with the boards in the I/O unit. The IOUI must be strapped for loopand unit numbers. It is normally installed in Slot 1 of the I/O unit.

Figure 2-40. The I/O Unit Interface (2000126-001)

Options Available

• Loop and unit strapping to select the desired loop and unit numbers.


1. Set the loop and unit straps, if not already set correctly for your system (factory set at Loop 1, Unit 21).Refer to ‘How to Select a System Address” (page 2) for further information. The loop number is set inthe DIP switch labeled U33 (at grid location 8C), and the unit number is set in the DIP switch labeledU35 (9G). The strapping method is shown in Figure 2-47, and is a binary entry of the number selected(the switches are not positioned one above the other as shown). The DIP switches are outlined in Figure2-47.

I/O Unit Interface (2000126-001) (Continued)

5. Set the equipment power switch to the “ON” position. The IOUI will perform a self-test sequence onpower-up, which may be reactivated by pressing the push-button “RST” switch, S1 (at grid location10G). The four LEDs (10D) (one red, one yellow, and two green) should all flash “ON” for approximatelyone second, and then go “OFF” in the normal self-test sequence. After the self-test, normal operatingconditions will cause the green LEDs (D7 and D8) to flash. If the red LED does not remain on after 30seconds, the board is operational and the installation is complete.

If the red LED (D10) does remain “ON” then the board has failed the test. When the red LED is “ON” theyellow LED (D9) blinks the error code. The number of blinks is the error number. After the yellow LEDblinks the code, it will stay off about five seconds before repeating the sequence.

After determining the error number, refer to Table 2-4 for the type of error and corrective action to betaken.

10. Set the equipment power switch to the “ON” position. If no red LED remains on after 30 seconds, theboard is operational and the installation is complete. The following paragraphs explain LED codes andfailure modes.

The PI will perform a self-test sequence on power-up, which may be reactivated by pressing the push-button “RST” switch, SW1 (at grid location 10E). The eight center LEDs (two red, one yellow, and fivegreen) should all flash “ON” for approximately one second, and then go “OFF” in the normal self-test se-quence. After the self-test, normal operating conditions will cause some of the green LEDs to flash. Ifany of the red LEDs remain “ON” after the self-test sequence, or if a yellow LED continues to blink, thenthe board has not been installed properly, or the board is defective (see Table 2-7 for LED error code ex-planations). After the yellow LED blinks the error code, it will stay off about five seconds before repeat-ing the sequence.

HOST Computer Interface (2000171-001)

The HOST Computer Interface-Hiway (HCI-H) Figure 2-64 is a two board set consisting of a HCI-H InterfaceBoard (2000130-003), Figure 2-65, and a HCI-H Memory Add-On Board (2000170-002), Figure2-66, plus an interconnecting cable (1682002-400). The HCI-H may be installed in either an analyzer or anI/O Unit. The two boards should be installed in adjacent board slots, with the memory add-on board to theleft.

It must be strapped for unit number. Since the HCI-H is an independent device on the Data Hiway, its unitnumber will be different from the device in which it is installed. The Data Hiway and the HOST computer se-rial line are connected to the field terminals for the slots containing the two boards.

HOST Computer Interface Hiway (2000171-001) (Continued)

Figure 2-67 illustrates a simple but typical multidrop HOST Computer Network. A HOST Computer, an Ad-vance Data Hiway and an Other System are each connected to the multidrop serial line through interfaces.The HOST initiates all communication. It requests Device Number 1 (in this example) to communicate withthe Advance Data Hiway and Device Number 2 to communicate with the Other System. Device Number 1must have been strapped at the HCI-H Memory Add-On Board.

Typical communications are as follows:

The HOST may request either analyzer status (is a contact open) or analyzer data (component concentra-tion).The HOST may send either status (Run, Hold, Calibrate, etc.) or data (engineering units high).The HOST may perform system tests.

The HCI-H data is formatted for analyzers with either a maximum of 9 streams and 9 components or amaximum of 8 streams and 8 components. Consider the term “formatted” analyzer to mean the data spacecontaining, for example, 9 streams and 9 components, and the term “actual” analyzer to mean an AdvanceAnalyzer on the Advance Data Hiway. If “actual” analyzer number 10 has 6 streams and 12 components perstream (exceeding 9 components), the HCI-H would store data under “formatted” analyzer numbers, for ex-ample, 10 and 11. The HOST programmers must be aware of this when communicating with equipment onthe Data Hiway.

Figure 2-67. Typical Multidrop HOST Computer Network

72


Options Available

• Loop and unit strapping to select the desired loop and unit number (see pages 2 and 3). The loop num-ber is defined to be 1 by the software for boards with PROM revision level below 4.3. For boards withPROM level 4.3 or higher set loop to actual number.

• Baud rate strapping to select the baud rate. Baud rates of 110 to 9600 are available.

• The HCI-H Interface Board is a multipurpose board and serial output of either RS-232C, 20 ma currentloop or logic level signals are available. When the HCI-H Interface Board is used as a part of the HCI-Hset, RS-232C must be strapped.

• Device number strapping to identify the HCI-H on the multi-drop serial line. Device numbers from 1 to255 are available.

• Jumper selection of the number of streams and components on “formatted” analyzers as seen by theHOST computer. Selection of either 9 streams and 9 components or 8 streams and 8 components isavailable.

• The serial data format is software set for 8 bits, odd parity, 1 start bit, 1 top bit.


1. Set the loop and unit straps on the HCI-H Interface Board, if not already set correctly for your system(factory set at Unit 30; for boards below PROM 4.3 Rev. the loop must be set to 1). Refer to “How toSelect an Address for Hiway Devices” (page 3) for further information. The unit number is set in the DIPswitch labeled U26 (at grid location 7B). The strapping method is shown in Figure 2-68, and is a binaryentry of the number selected. See Figure 2-64 for the unit number DIP switch location.

Figure 2-68. Loop & Unit Strapping for the HCI-H Interface Board

73


2. Set the HCI-H Interface Board DIP switch U10 (4B) if not already set correctly for your system (factoryset at 9600 baud). See Figure 2-64 for the DIP switch locations. Figure 2-69 illustrates the method ofsetting each of the available baud rates. The baud rate must be set to match the HOST computer sys-tem requirements.

• For boards with PROM level below 4.3 U10 and U27 must be set to same value.

• For boards with PROM level at or above 4.3 loop (U27) can be set to actual loop value.

Figure 2-69. Baud Rate Strapping for the HCI-H Interface Board

3. For all boards U43 DIP switches must be set for proper operation; reference Figure 2-68.

4. Check to be sure that the RS-232C output has been selected on the HCI-H Interface Board with the pro-gramming plug, refer to Figure 2-65. The plug should be inserted in socket U2 (2F), labeled SP2 RS-232, for RS-232C output. The plug is symmetrical, and may be installed two ways. For normal opera-tion, install pin 1 of the plug to match pin 1 of the socket. When power is applied, the red “TST” LED willbe “ON” if installed incorrectly (in the test mode). Strapping for current or logic level is not allowed.

5. Set the device number with the DIP switch labeled U15 (3D) on the HCI-H Memory Add-On Board. Referto Figure 2-65 for the switch location.

The device number identifies the HCI-H to the HOST computer on the multi-drop serial line. The softwareprotocol implemented on the HCI-H requires that the HOST “address” (with the device number) the HCI-H each time the HOST wishes to communicate. The device number can be any number from 1 to 255.The particular device number to which the HCI-H will respond is set by these straps. The device numberchosen is specified by the HOST application programmers. The factory setting is 1.

The strapping method is shown in Figure 2-70. The device number is strapped as a binary entry of thenumber selected.

74


Figure 2-70. Device Number Strapping for the HCI-H Memory Add-On Board

6. Select the maximum number of streams and components with the jumper labeled JP1 (1D) on the HCI-H Memory Add-On Board. Refer to Figure 2-65 for the jumper location.

If your HOST computer is configured for 9 streams per analyzer and 9 components per stream (the fac-tory setting), check to insure that no shorting jumper is installed at JP1.

If you have a HOST computer configuration that requires 8 streams per analyzer and 8 components perstream, this may be selected by soldering a shorting jumper wire across the two plated through holes inthe printed circuit board at JP1.

7. Connect one end of the ribbon cable (the end with the 28 pin DIP plug) to the RAM socket labeled U28(8G) of the HCI-H Interface Board (located in Figure 2-64). Connect the other end of the ribbon cable tothe socket labeled J1 (10F) of the HCI-H Memory Add-On Board.


9. Select the board slots for the two HCI-H boards (refer to pages 4 and 5). Install the HCI-H Interfaceboard in the right most of the two selected slots and the HCI-H Memory Add-On Board in the left mostslot. Push the boards securely into the connectors.

10. Install the field wiring for the HCI-H board set as shown in the wiring diagrams of Figures 2-71 and2-72.

75


Refer to Figure 2-71 when connecting to a multidrop serial line.Refer to Figure 2-72 when connecting directly to the HOST Computer.

Wire size 22 AWG, or larger, unshielded may be used to interconnect the HCI-H Interface Board andthe Memory Add-On Board field terminals.

The serial line should be wired with wire size 22 AWG, or larger shielded twisted pairs.

The Data Hiway wiring is described in step 10 below.

Figure 2-71. HCI-H Field Terminal Wiring Diagram for a Multidrop Serial Line

76


Figure 2-72. HCI-H Field Terminal Wiring Diagram for Direct HOST Connection

77


10. The data hiway field wiring depends on where the HCI-H is installed.

If the HCI-H board set is in the analyzer, interconnect the HCI-H Interface Board field terminals with theAnalyzer Termination Board (ATB) terminals as shown in Figure 2-73. Note: The proper ATB terminalsare on terminal strip T5 on the right edge of the ATB board, NOT terminal strip T4 on the top edge of theboard. Unshielded wire size 22 AWG or larger may be used inside the analyzer. Route these wiresaway from nearby power wires.

Figure 2-73. HCI-H Data Hiway Wiring to ATB

If the HCI-H board set is in the I/O unit, interconnect the HCI-H Interface Board field terminals with the I/OUnit Interface Board (IOUI) terminals as shown in Figure 2-74 (the IOUI is normally in slot 1). Recommendedwiring is Belden 9182 cable (186002-001) or equivalent. Wire one cable for each channel. Ground the shieldat one end only (grounding to the IOUI is recommended in the I/O unit). Refer to Appendix A for Data Hiwayinstallation and termination instructions.

Figure 2-74. HCI-H Data Hiway Wiring to IOUI

78


11. Set the equipment power switch to the “ON” position. If no red LED remains “ON” after 30 seconds, theboard is operational and the installation is complete. The next paragraph explains the LED codes andfailure modes.

The HCI-H will perform a self-test sequence on power-up, which may be reactivated by pressing thepush-button “RST” switch, SW1 (at grid location 10E). The eight center LEDs (two red, one yellow, andfive green) should all flash “ON” for approximately one second and then go “OFF” in the normal self-testsequence. After the self-test, normal operating conditions will cause some of the green LEDs to flash. Ifany of the red LEDs remain “ON” after the self-test sequence, or if a yellow LED continues to blink, thenthe board has not been installed properly, or the board is defective (see Table 2-8 for LED error code ex-planations). After the yellow LED blinks the error code, it will stay off about five seconds before repeat-ing the sequence.

The green LEDs indicate the operational status; GS1 = DH RECV, GS2 = DH XMIT; GS3 = HOSTRECV; GS4 = HOST XMIT, GS5 = HOST ALIVE.

Low Volume Filament Detector Circuit Wiring


2. Power to Detector Amplifier Board

The power requirement for the Detector Amplifier Board is ±15 volts at 0.090 amps maximum.

Three ga. Wires are used to bring +15V, -15V, and GND from the screw terminals on the left side of theAnalyzer Masterboard to the respective terminals on the Detector Amplifier Board (Figure 2-99). Theselines should be twisted together, run down the left back corner and across the bottom of the ElectronicsEnclosure.

3. Signal wires

A shielded pair cable should be used to route the output signal (V+, V-) from the Detector AmplifierBoard to the Analyzer Termination Board (R+, S+). The shield should be connected to ground on theATB by use of the mounting screw near the -10 terminal (Figure 2-99).

In addition, two 680 ohm resistors are connected from +10 volt on the ATB to R- and S- on the ATB.These resistors disable the constant temperature op amps on the ACB thermistor detector circuit, andallow it to function as a differential input circuit.

4. Filament connections

The red/white pair and orange/black pair of wires from the detector seal should be connected to the R-/R+ and S-/S+ terminals (respectively) on the Detector Amplifier Board.

Note: The ITC signal wires connect directly to the ATB in the same manner as when using the tradi-tional thermistor detector.

Appendix A. OPTICHROM ADVANCE Data Hiway Termination Box

Description

The Data Hiway contains two communication channels A and B, for improved reliability. When both chan-nels are operable, they share the communication load. If one channel, or part of one channel is inoperable,the other channel automatically takes over the communications load.

Data Hiway Limits

A Data Hiway is limited to 31 device connections (plus one NIU connection). Up to 8 Data Hiways may beconnected together with NIU (for a maximum of 248 devices).

The total length of a Data Hiway is limited to 5000 feet. This means the total capable in the longest channel(if they are different) plus the sum of the lengths of any branches, NOT the distance between the furthermostdevices.

If more than 300 feet of Data Hiway is required, the hiway may need to be terminated, see step 3 of the in-stallation procedure.


Step Procedure

1. Set the equipment power switches for all devices to be connected to the Data Hiway to “OFF”.

2. * Install the dual Data Hiway cable to each of the devices to be on the hiway. The cables must beAlpha 516689 (Siemens Applied Automation, Inc. Part No. 1686002-002) or equivalent, nominal 8.5pF per foot. Refer to the installation manual of each device for proper connection to that device.Ground the shield of each cable at one end only.

Run the cables in accordance with the pertinent electrical codes and regulations.

To significantly simplify the installation, use a daisy chain configure; see Figure A-1. Other configu-rations can be used but the installation locations for termination resistors must be determined in thefield experimentally and Hiway performance will be degraded.

* Two Data Hiway single pair cables (one each for Channel A and B) (Belden 9182 – Siemens AppliedAutomation, Inc. Part No. 1686002-001 or exact equivalent) may also be used with the box, butcolors will not match those on the silkscreen and Channel A and Channel B will have redundantcolors.

Step Procedure

3. Termination of Data Hiway connections is necessary in most configurations due to half wave lengthreflections and hiway load.

Both channels should be terminated (as shown in Figure A-1) with a series 330 ohm quarter wattresistor (Siemens Applied Automation, Inc. Part No. R65210) and a 0.002 microfarad 1000 volt ce-ramic disc capacitor (C08450) or suitable substitutes.

Figures A-1 and A-2 illustrate which devices require termination. Termination is required only on thedevices indicated by a box containing a T.

As shown in Figure A-2, only the two ends need to be terminated if the Data Hiway is daisy chainedand contains no branches greater than 300 feet long.

4. Perform Data Hiway Post Installation Test; see page 112.

5. Set the equipment power switch for each device to “ON”. Each device will perform a self-test onstart-up. Information on the self-test and corrective action on failure may be found in the appropriatedevice installation manual or the System Maintenance Manual (2000530-001).

How to Test the Data Hiway

Post Installation Test

The following test procedure tests the Channel A and Channel B Data Hiway cable connections. These testprocedures insures that the signal lines are correctly installed.

Referenced testing points are CH A and CH B positive (+) and negative (-) and shield ground termination’s.

Test Equipment

The following test equipment is required to test continuity of installed Data Hiway Channel A and Channel Bsignal lines:

• 9 Vdc battery, with connector lead and clips• Digital Volt Ohm Meter (DVM) or equivalent• 10K ohm resistor, with leads and clips

Measuring Signal Line Continuity

Data Hiway Channel A and Channel B + and - signal line continuity can be checked by performing the fol-lowing procedures. Devices can be operating on the Data Hiway when making continuity checks. Performthe check for each device connected to the Data Hiway.

Do not skip testing any devices connected to the Data Hiway. Check at the incoming termination’s on theI/O Chassis, the Termination Boards in the Analyzer Electronics Enclosures, LINC units and any other DataHiway devices. Typical problems are reverse polarity, poor contacts on wiring terminals, opens, shorts andcross channel wiring. Every point in the Data Hiway wiring should be carefully checked to ensure correctwiring.

Step Procedure

1. Connect the positive lead of the 9-volt battery through the 10K ohm resistor to Channel A (+) termi-nal and connect the negative lead of the battery to the Channel A (-) terminal at any connectionpoint on the Data Hiway.

2. Using DVM measure for 9.0 Vdc across Channel A (+) and Channel A (-).

3. Repeat steps 1 and 2 for Channel B.

Measuring Shield Continuity

Data Hiway shield continuity can be checked by performing the following procedures:

Ground Data Hiway cable shields at only one end of each segment. This practice reduces ground loopnoise.

Step Procedure

1. With Data Hiway communicating with connected Nodes, temporarily disconnect Channel A shieldlead from ground.

2. Connect 10K ohm resistor to disconnected shield and connect battery positive (+) lead to resistor.Resistor should be in series with the battery. Connect battery negative (-) lead to unit ground.

3. Connect DVM positive (+) lead to channel A and connect shield and negative (-) to unit ground.Measured voltage potential should be 9 Vdc.

4. If 9 Vdc is not measure, the channel A shield line is grounded at another point, correct problem.

5. Reconnect channel A shield lead.

6. Repeat steps 1 through 5 for Channel B.

7. Repeat steps 1 through 6 for each shield ground point on the Data Hiway cable.
