Configuration and calibration programming is entered with three hiddenkeys�keys not intended for end-user access. A hidden programming keyaccesses the set-up modes, and two hidden arrow keys select and enterdata within the set-up modes. The hidden keys also access the internal rawcounts value and the software release number. Figure 1 below shows thelocations of the hidden keys on the Model 615/XL.

The three hidden keys are touch-sensitive, as are all the keys on the Model615/XL. However, unlike other keys, the three hidden keys do not have keyfaces. These keys are hidden from end users because access to the set-upmodes is intended only for trained technicians who use this service manual.

Determining Axle Sizes

Determining a Configuration Code

To use the configuration code chart in Table 2 for determining an appropri-ate configuration code for your weighing system, you must first know thecalibration axle size of the Weigh Bar(s) or alternative weight transducer(s).Physical axle size (the measured diameter of a bar) and calibration axle size(the measurement marked on a bar) are not the same for some Weigh Bars.Read about the following combinations of physical axle sizes and calibrationaxle sizes, and follow the guideline that applies to your bar(s):

� If your weight transducer measures five-eighths inch (5/8") in diameter,but is marked with a calibration axle size of 2-1/4" D (Dual), use datashown in Table 2 for a five-eighths-inch (5/8") bar.

� If your weight transducer measures one inch (1") in diameter, but ismarked with a calibration axle size of 2-1/8", use data shown in Table 2for a one-inch (1") bar.

� For weight transducers which have a physical axle size of either five-eighths inch (5/8") or one inch (1"), but which are marked with acalibration axle size other than 2-1/4" D or 2-1/8" respectively, use datashown in Table 2 for Custom Sensitivity and Capacity x Increment.

� For all other weight transducers: Whether the physical axle size of thebar and the calibration axle size marked on the bar do or do not match,use data shown in Table 2 for the calibration axle size marked on thebar.

Table 1 is an example of a set of configuration choices for a Model 615/XLweighing system. Table 1 shows you how selections for the Model 615/XL�sconfigurable parameters would be represented by a configuration code of5121, according to the configuration code chart in Table 2. You can see thateach digit in the code represents a parameter, and the value of each digitrepresents a selection for that parameter as shown in Table 2.

Table 1A Sample Set of Configuration Choices

andIts Corresponding Configuration Code (5121)

Parameter Represented Selection Config.by Code

Axle size 2nd digit 2-1/8" 5Capacity X increment size 3rd digit 20k x 2 1Auto zero tracking 4th digit ±1.0 division 2Units of measure and Capture mode 5th digit Ib/On 1

Configuration code 5121 uses only the2nd, 3rd, 4th and 5th of five available digits.


The sample configuration code, shown in bold type in Table 1, may bewritten horizontally, with digit places numbered, as follows:

Sample configuration code: 5 1 2 2Digit place #s: 1 2 3 4 5

Remember, a four-digit configuration code uses digit places #2, #3, #4, and#5, but not #1. Digit place #1 is to be used only if the configuration code hasfive digits. Five digits are required only for bars with calibration axle sizes of3-1/8 inches and 4 inches and when custom sensitivity (with capacity xincrement) is appropriate (See Table 2).

Determining the Custom Sensitivity RatingThis procedure allows you to configure a sensitivity rating for a weighttransducer that is not referenced in Table 2. You may configure anothermanufacturer�s weight transducer for interface with the Model 615/XL.Before starting the keying procedure for configuring custom sensitivity, youmust verify three facts about the transducer(s) being used:

� Trade name of the transducer� Sensitivity rating of the transducer� Capacity x increment size of the transducer

Trade Name of the TransducerTo configure custom sensitivity for Weigh-Tronix Weigh Bars, see the nextsubsection, Sensitivity Rating of the Transducer.

To configure for transducers from manufacturers other than Weigh-Tronix,refer now to instructions located in the Programming Appendix. If you findthat custom configuration of sensitivity is required for your transducer(s),return to this section and proceed to the next topic.

Sensitivity Ratings of the Transducer1. Determine the sensitivity rating, that is, the mV/V output at full capacity,

for the weight transducer(s) you are using. You will probably find thisinformation stamped or printed on the transducer.

2. Call the factory at 1-800-458-7062 for help in determining the Model 615/XL sensitivity rating for your transducer(s). Because a number ofdifferent types of bars are used by various manufacturers of weighttransducers, it is impossible to provide generic instructions on determin-ing Model 615/XL sensitivity ratings for all the weight transducersavailable.

3. Write down your calculated sensitivity rating here us-ing the following format:

n. nnnnnnn = your sensitivity rating1 2345678 = digit places

You may key in a mV/V value of up to eight digits. Selection range forsensitivity is from 0.075 to 6.0 mV/V. Keep your notation handy for entryin steps 5, 6, 7, and 8 of the following keying procedure.

Capacity x Increment Size of the Transducer4. Refer to Table 5 and locate a capacity x increment size combination that

is appropriate for your Model 615/XL.

5. Look on the right end of Table 5, and identify the number of the row inwhich your selected capacity x increment size is located. Then writedown that row number here: __________________

You will need this row number in step 11 of Keying In the CustomSensitivity Rating.

This printed circuit card contains the

� Power Supply� Analog-To-Digital Circuitry� Microprocessor Circuitry� Display Circuitry.

This indicator, which is energized by 10 to 18 vdc in reference to a NEGA-TIVE GROUND utilizes one five amp fuse mounted on the bottom of thechassis for current protection. (Systems with a positive ground are modifiedby cutting jumpers from E11 to E12 and E9 to E10. Then install jumpersfrom E9 to E12 and E10 to E11.)

The circuit card receives power from the fuse at P2 and is protected againsthigh voltage transients with varistor RV1.

Input voltage is monitored by 16 volt zener diode VR2. If the voltage acrossVR2 exceeds 16 vdc, Q3 will turn �ON� holding the power circuitry in the�OFF� condition. In addition, if the input voltage drops below 10 volts DC,PA7 disables the power circuitry by outputting a low signal.

A �Power On� command is generated when the ON key is pressed. Thisturns Q5 on and provides a low signal to +8v regulator (u18) pin1 enableinput. When the power is turned off, the Q5 turns off, the Q4 turns on and ahigh signal disables (U18) the +8 regulator and turns it off.

Circuit Descriptions

Main Printed Circuit Card

Power Supply

To prevent the unit from turningoff below 10 volts, remove CR5and C36. When configured thisway, the unit will return to theGross mode if it loses power.


The -7.5 vdc supply voltage is established by U7, a voltage convertor. Thisdevice inverts the input voltage to a -7.5 vdc level.

The +5 vdc voltage is provided by U8, a 7805 regulator.

As soon as the +8 volt power supply voltage is present, Q2 turns on whichturns on the DS2 and DS3 LEDS

The analog-to-digital circuitry consists of two weight voltage amplifiers (U1and U2), a reference amplifier (U3), an analog switch (U4), switch controllogic gate (U14C), a dual slope integrator (U5), and a comparator (U6).

An 8 vdc excitation voltage is supplied to the weight sensors from P1 pins 1and 6. The millivolt signal received back from the weight sensors enters theanalog-to-digital circuitry at P1, pins 3 and 4.

This millivolt signal is amplified and filtered by U1 and U2 to establish theamplified weight voltage (0 to +9 vdc) at U2 pin 6. This weight voltage isthen provided to U4 pin 5. A logic low during the weight voltage interval atU4 pin 1 enables the amplified weight voltage to be received by the dualslope integrator (U5). Starting at zero volts, the integrator capacitor (C20)charges at ramp angle directly proportional to the amplified weight voltagebut of opposite polarity. As the amplified weight voltage increases, theintegrator output ramps more in the negative direction.

The voltage received from the sense lines enters the analog-to-digitalcircuitry at P1 pins 2 and 5. This sense voltage establishes a referencevoltage of -9 vdc at U3 pin 6. The reference voltage is applied to U4 pin 10.

After the integrator capacitor has been charged for a fixed period of time,the Weight Voltage Interval, U4 pin 1 goes high. U14 applies a logic low topin 14 of U4 which allows the reference voltage to be applied to the integra-tor. Since the reference voltage (-9 vdc) is of opposite polarity to the ampli-fied weight voltage, it causes the integrator output to ramp back toward zero.(This period of time is known as the Reference Voltage Interval.)

While the integrator output is ramping back to zero, the comparator (U6)signals the microprocessor to record this period of time in clock pulses. Themicroprocessor uses this number of pulses to calculate the amount ofweight on the scale.

When the integrator reaches zero, the comparator output goes low whichtriggers U14C to remove the logic low at U4 pin 14 completing one analog-to-digital cycle.

This analog-to-digital conversion repeats at a frequency of 30 hertz.

Analog to DigitalCircuitry


MicroprocessorCircuitry

The Microprocessor Circuitry consists of a Motorola MC68HC11A1 8-bitmicroprocessor IC (u11), a 74HC573 tristate latch (U12), a 27C128 EPROM(U13), and various other components.

The microprocessor features on chip memory 256 bytes of RAM, 512 bytesof EEPROM, along with a Computer Operating Properly (COP) watch dogsystem.

A 2 MHZ internal clock is contained in the microprocessor and is controlledby an external crystal (Y1). Output (ECLK) from this clock provides timingreference for the EPROM (U13), and input to voltage monitoring circuit U9.

The microprocessor communicates with Analog-to-Digital switch controllogic gate U14 through ports PA2 and PA6. Through U14, the timing refer-ence for the Reference Voltage Interval and Weight Voltage Interval areprovided.

The switches on the front panel receive a signal from ports PD2-PD5 on themicroprocessor and they are monitored for an electrical change by portsPE0PE3 on the microprocessor.

As signals are received by the microprocessor, it will send them to theEPROM (U13) on the address lines A0-A15. The signals will be translatedand held by U12. Once all translating is completed, the microprocessor willenable U12 to return the new information on data lines D0-D7 to the micro-processor. Then, the appropriate device will receive a signal from themicroprocessor.

The Computer Operating Properly (COP) watch dog system in the micropro-cessor detects errors introduced by electromagnetic interference. If an erroris detected, the microprocessor is reset and operation continues. When theindicator is powered up, the momentary displayed "hi" message, indicatesthe watch dog system is active.

If a "hi" message is displayed, the indicator will perform correctly, but will notbe guarded by the COP watch dog system. This may happen when a newmicroprocessor IC is installed. The COP watch dog system can be activatedby following this procedure:

� Turn the indicator OFF jumper P7-1 to P7-2 and P6-1 to P6-2� Turn the Model 615/XL ON for a few seconds� Turn the Model 615/XL OFF� Remove the jumpers


Display Circuitry The six digit liquid crystal display (DS1) features black segments against asilver transflective background.

Liquid crystal display driver U15 requires a +5 vdc power supply and twosignal inputs from the microprocessor to function: (1) a 33-bit serial datainput and (2) a microprocessor controlled input. When both of these condi-tions have been met, the display driver will energize the appropriate seg-ments on the display.

Additional circuitry required to provide either an RS-232 communicationsinterface or a remote display interface requires R49-57, C48-51, U16, U10,and P6 connector.

The RS-232 transmitter/receiver (U10) internally generates +10v and -10 vsupplies and meets all EIA RS-232C specifications. Through U10, themicroprocessor communicates with peripherals which will accept the follow-ing protocol: baud rate 1200, 1start bit, 8 data bits, no parity, and one stopbit. The RS-232 communications port supports X-on (HEX 11), X-off (HEX13_) handshake and responds to an inquire character (HEX 05) printrequest.

The invertor/buffer gates (U16) are used in the remote clock, remote data,remote zero, and remote print lines to provide isolation and assure properlogic; levels to and from the remote display.

P6 connector provides external access to power supply voltages, RS-232data lines, remote display drive lines, remote zero lines, and remote printlines.

After installing PC board assembly P/N 27643-0030 as shown in assemblysection, plug 3 pin cable assembly into P8. This enables user to haveremote zero capabilities within the Model 615/XL. Be sure to match dipswitch selections between receiver card and transmitter.

MODEL 615 / 615XL INDICATOR 12VDCXM710-L WIRELESS REMOTE INSTALLATION

39

The XM710-L hand-held transmitter provides the ability to remotely perform a zero/reset command and can be installedin MODEL 615 / 615XL or RD712 / 712XL. The XM710-L wireless remote system is similar to those used on garage dooropeners. For selectable security, the transmitter and receiver assembly boards have programmable security code switches.The eight position switch is used to determine the security code. These can be programmed to a different code, but theprogrammed code must match on both the transmitter and receiver.The unit is shipped from the factory with the following settings:

1, 3, 5, 7 = ON (closed)2, 4, 6, 8 = OFF (open)


Programming AppendixTo determine an appropriate configuration code for J-Star or Eaton trans-ducers, consult Table 9 for Eaton or Table 10 for J-Star.

The Eaton Configuration Code Chart (See Table 9) shows you how selec-tions listed below for five configurable parameters would be represented bya configuration code of 4121. Notice that each digit in the code represents aparameter, and the value of each digit represents a selection for that param-eter as shown in Table 9: Eaton Configuration Code Chart.
