3.3 Cabinet Theory of Operation The main AC power enters the ASTC-6 Cabinet through position 12 on field terminal block FT2, located on the field termination section of the rack assembly. The AC– and equipment ground inputs are terminated on their respective busses. The AC+ input is wired to the Main and Equipment circuit breakers located in the Power Distribution Assembly.

The ASTC-6 Cabinet has three modes of operation: NORMAL, FLASH and OFF. The mode of operation selected depends on the settings of two switches on the Rack assembly in the Cabinet. The ON/OFF switch, when placed in the OFF position, causes the cabinet to be in the OFF mode, no matter what condition the other switch is in. The AUTO/FLASH switch, in the AUTO position allows normal operation. When placed in the FLASH position, the cabinet transfers to a flash mode. A third switch, the door switch, operates in conjunction with the Model 2010ASP-NYC Conflict Monitor. If the Conflict Monitor is removed and the Cabinet door is closed, the Cabinet will switch to the FLASH mode.



3.3.1 Normal Mode

In the normal mode, the traffic lights are controlled by the loadswitches, which in turn are under the control of the Bus Interface Unit via SDLC communication with the ASTC Controller’s program control.

The 120 VAC is distributed as follows: The current flows through the Main circuit breaker (MCB), through the closed contacts of mercury contactor MC1, through the two signal bus circuit breaker (CB-A and CB-B), through the loadswitches (L1 – L6) in the output section of the Rack Assembly, and out the terminal blocks (FT1 and FT2) to the traffic lights. If the Molex jumper block is selected for Red Flash, the current to the red light circuits flows through the closed contacts of the normally open Flash Transfer Relay (closed due to the application of 120 VAC to the coils of the relay) before going to the field terminals. The mercury contactor is normally open and closes when its coil is energized. The coil is energized when the cabinet is in the normal mode of operation and will de-energize when any of the switches are in the Flash, Off or closed position or when the monitor unit detects a malfunction.



3.3.2 FLASH Mode

In FLASH mode, the loadswitches are bypassed, and certain red or yellow lights, depending on the jumper block selected, are connected to the flasher unit. This flasher unit alternately illuminates and extinguishes the signal lights at a rate of 50 to 60 flashes per minute.

In FLASH operation, 120 VAC is removed from the coil of the mercury contactor. The mercury contactor’s contact then open, removing the 120 volts from the loadswitches, and thus the light. At the same time, the voltage applied to the coil of the flash transfer relay is removed causing the relay to de-energize. This results in the closed contacts of the heavy-duty flash relay closing, completing the current path from the flasher unit through the rack assembly. The heavy-duty flash transfer relays now switch the pulsating current from the flasher unit directly to the red lights, bypassing the loadswitches. If the cabinet is configured for yellow flashing, then the yellow lights are connected to the flasher.

The intersection will also transfer to FLASH mode if the Conflict Monitor detects a malfunction. These include the following basic monitor functions:

• Conflicting green or yellow indications

• Absence of +24 VDC to the monitor unit

• Absence of a watchdog timing pulse

NOTE: Refer to the 2010ASP-NYC Conflict Monitor Manual for a full list of monitor functions that force a transfer to FLASH mode.



3.3.3 OFF Mode

In the OFF mode, all traffic lights are completely de-energized.

In this mode, 120 VAC is applied to the Flash Transfer Relay, which prevents the flasher from connecting to the red light circuits. Also, with the Signal switch in the OFF position, current is prevented from passing through the coil of mercury contactor MC1, thus removing power from the loadswitches. As a result, all traffic lights remain dark.



3.4 Manhattan Operation The ASTC controller operating in the ASTC-6 cabinet supports the Manhattan Communica-tions Protocols for communication with New York City’s Vehicular Traffic Control System (VTCS). The interconnect uses a Remote Communications Unit (RCU) operating with a revised RCU firmware. All functionality of previous versions of the RCU is now incorporated into the ASTC Controller firmware. The sole function of the revised RCU is to convert RF signals to serial data for processing by the ASTC controller.

A Manhattan deployment requires the following equipment:

• Remote Communication Unit (with revised firmware)

• RCU power plug

• RCU communication harness connecting to ASTC controller

• VIDT

• (2) RCU coaxial cable (transmit and receive)



3.5 DCI Operation The Outer Boroughs employ a traffic system that uses a ±100 VDC pulsing method for communication between the VTCS and existing traffic intersection controllers. To allow the ASTC controller to operate within this system, a DC Interconnect (DCI) Module is used. The DCI module provides an interface between the existing New York City VTCS and the ASTC Controller. The purpose of the DCI is to convert the ±100 VDC pulses to the logic levels required to interface with the ASTC controller via the cabinet’s BIU.

The equipment required for a DCI Deployment is as follows:

• DCI Module

• Demarcation termination block

• Telephone cable wiring



3.6 Manual Operation The ASTC-6 cabinet provides a Manual Mode of operation that allows an operator to control the ASTC controller by means of a hand-operated switch. This will allow the operator to manually control the progression of the controller through its programmed intervals.

This is done using Manual Police Cord that has a pushbutton switch on one end and a Phono Plug on the other. Upon the insertion of the phono plug into the cabinet’s Manual Control Jack, the Manual Control Enable signal is applied to the controller. This causes the ASTC controller to stop timing in all intervals except the vehicle change and clearance intervals. When the pushbutton is pressed, the controller steps to the next clearance interval. Normal operation resumes upon the removal of the phono plug.

ASTC-6 Cabinet - Technical Manual Cabinet Description


4. Cabinet Description The ASTC cabinet consists of three basic assemblies: Header Panel Assembly, Power Distribution Assembly, and Rack Assembly (see drawing in Section 8.1).

Cabinet Description ASTC-6 Cabinet - Technical Manual


4.1 Header Panel Assembly Each ASTC cabinet is equipped with a header panel assembly located at the top of the cabinet. The assembly contains a thermostatically controlled fan, a thermal alarm sensor with an indicator, and a controller power outlet receptacle. This assembly is connected to the cabinet via the PDA#3 harness, which mates with the PDA#3 connector on the Power Distribution Assembly.

The electric fan has an air moving capacity of 100 cfm. The fan vents air out between the top of the cabinet and the cabinet front door. The front door is provided with louvered vents and a removable air filter. The fan is thermostatically controlled and manually adjustable to operate at any temperature between 90° - 150° F (33° - 65° C) with a differential of not more than 43° F (6° C) between automatic turn on and turn off. The fan unit power is provided by the equipment circuit breaker located in the power distribution assembly. A ¼-amp fuse protects the cabinet fan circuit.

Also provided on this assembly is a fixed temperature sensor used to provide for a Thermal Alarm closure contact. This sensor will provide an alarm signal to the Bus Interface Unit when the cabinet’s internal temperature reaches 150° ± 5° F (65° C). A visual indicator of the thermal alarm condition is also provided.

A controller duplex receptacle outlet is provided to supply Filter AC+ for use by the controller. A 10A fuse in the PDA protects this receptacle.

Two switches are wired to this assembly and are mounted on the top right corner of the door opening. The Conflict Monitor Interlock prevents the cabinet from operating without a Conflict Monitor installed when the door is closed. The door Alarm switch provides the controller with an active input to indicate that the cabinet door is open.



4.2 Power Distribution Assembly The Power Distribution Assembly (PDA) functions as the entry point for AC power to the cabinet and contains main and secondary circuit breakers, cabinet transient and voltage surge protection, clean power filtering, and a +24 VDC power supply. The major components of the PDA includes the following:

• (1) One-pole, 30 A 120 VAC Main Circuit Breaker

• (1) One-pole 15 A 120 VAC Equipment Circuit Breaker

• (2) One-pole 15 A 120 VAC Signal Bus Circuit Breaker w/ Auxiliary Switch

• (1) Duplex NEMA 5-15R Ground Fault Interrupt Equipment Receptacle

• (5) Fuses o DC Power Supply AC Fuse (1A) o DC Power Supply Output Fuse (2A) o Flasher Unit Power (15A) o Controller Unit (10A o 12 VAC (1/4 A)

• (1) DC Power Supply Indicator (AC+, +24VDC)

• (1) DC Power Supply Test Points (+24VDC, Lgc Gnd)

• (1) 12 VAC LED Indicator

• (1) 60 Amperes Mercury Contactor, 120 VAC

• (1) Surge Arrestor

The PDA is of a modular design and can be removed for troubleshooting purposes. The PDA mounts to the lower right section of the cabinet rack assembly and is fastened using two ¼-turn wing-nut fasteners. It has a side cover that may be opened during operation, but caution must be used since high voltage AC power is present inside the assembly. If any question exists regarding safety, it is best to remove power from the cabinet before opening the panel.

Interconnections to the rack assembly are made via connectors PDA1, PDA2, and PDA3 with the following pin assignment (see Table 1):



Pin PDA1 Function PDA2 Function PDA3 Function 1 Signal CBA CM Fail (Door Sw) AC+ (Filtered) 2 CM Fail (Fr PDA) AC- (Filtered) 3 CM Fail (To PDA) Chs Gnd 4 CM Interlock Equipment CB 5 Signal CBB Cabinet Alarm 6 12 VAC 7 Chs Gnd 8 AC– AC– 9 Flasher AC+ AC+ 10 11 Signal CBA MC Coil Door Switch (Intlk) 12 Lgc Gnd Door Switch (Intlk) 13 +24 VDC Door Mon/Therm Sensor 14 Lgc Gnd 15 Signal CBB +24 VDC

Table 1. PDA Pin Assignments

As its name implies, the PDA distributes power within the cabinet. Input power enters on the quick connect connector and feeds a 30 A Main Circuit Breaker (MCB). The main circuit breaker controls power to the controller receptacles, flasher fuse, +24 VDC power supply, and the mercury contactor (MC). The MC is a normally open switch rated at 60 A.

The PDA uses a cabinet Surge Arrestor to protect the cabinet from catastrophic electrical surges and high frequency noise. In addition, the Arrestor employs a Series Hybrid Inductor circuit, which provides additional filtering. The Arrestor has the following ratings:

• Peak Current......... 30,000 A (@ 8 x 20μs waveform)

• Clamp Voltage ...... 250V @ 30kA

• Response Time..... <5 ns

• Surge Life ............. 25 occurrences @ 10 kA (8 x 20 μs)

• Filtering ................. Line and Neutral to Ground

The mercury contactor provides power to two 15 A circuit breakers. These signal circuit breakers are wired to the Rack Assembly and feed the loadswitches as follows:

• CBA -- Loadswitch 1, 2, 5

• CBB -- Loadswitch 3, 4, 6



These two single-pole circuit breakers are equipped with an auxiliary switch feature and have a medium trip-delay characteristic. The normally closed contacts of the auxiliary circuit are connected in series with the cabinet flash system so that any tripped breaker shall cause the cabinet to transfer to the flash mode. The breaker’s auxiliary switch circuit shall be closed when the breaker is in the on position.

An Equipment Circuit Breaker (ECB) rated for 15 A with a short trip delay characteristics provides power to the GFI equipment receptacle and the cabinet fan. The GFI equipment receptacle with a ground fault circuit interrupter as defined in the National Electrical Code is provided on the front panel. Circuit interruption will occur on 6 mA of ground fault current and will not occur with less than 4 mA of ground fault current.

The Flasher fuse is rated at 15 A and feeds the Flasher units in the rack assembly to provide two alternating signal drives rated at a maximum of 15 A each.

A +24 VDC power supply is included in the PDA. The power supply module provides the +24 VDC needed for the operation of most of the cabinet control components. The unit is of a ferro-resonant design having no active components and conforms to the following requirements:

• Line regulation: 2 percent from 90 to 135 VAC at 60 Hz, plus an additional 1.6 percent for each additional one percent frequency change.

• Load Regulation: 5 percent from 0.5 A to 2.0 A with a maximum temperature rise of 86° F (30° C) above ambient.

• Design Voltage: +24 ± 0.5 VDC at full load.

• Full Load Current: 1.75 A

• Ripple Noise: 2 VPP and 500 mVRMS at full load

• Line Voltage: 90 to 135 VAC

• Minimum Voltage: +23 VDC

Power is derived from the filter portion of the cabinet arrestor and is applied through F1 (1A) to the primary side of the transformer. AC tuning capacitor (6 µF 660 VAC) is self-regulating and prevents variations in input voltage from affecting the output level of the power supply. The transformer drives a high capacity diode bridge rectifier along with one large 23,000 µF, 50 VDC filter capacitor, providing low ripple voltage at full-load (1.75 A) current. A parallel 1KΩ 1 W load resistor prevents any residual charge on the filter cap in the event of an open circuit operation after the power is removed. Fuse F2 (2A slo blo) protects against accidental overloading. Test points for the +24 VDC and DC ground are available on the PDA front panel.

Also provided in the PDA is an unregulated 12 VAC power supply. The 12 VAC is provided for use by the BIU for isolation of Pedestrian and Preempt inputs. Power is applied through F5 (1/4 A) to the primary side of the 12VAC transformer. The developed 12 VAC is protected from overloading by a 1/4 A resettable fuse. An LED indicator for the presence of this voltage is provided on the front panel. This LED is wired in series with a Zener diode which prevents the LED from illuminating when the voltage is below 7 VAC.



4.3 Rack Assembly The Rack Assembly combines the input, output, and field output panel into a single self-standing rack unit. This houses the Detector Cards, Load Switches, Flashers, FTRs, Conflict Monitor, Cabinet Address Card, Bus Interface Unit, DC Interconnect Module (if used), and maintenance switches. For ease of maintenance, the rack assembly is removable. The rack assembly utilizes a Printed Circuit Board Motherboard to reduce the number of cabinet wiring. All necessary connectors to mate with standard traffic equipment is mounted and interconnected on the motherboard. The rack assembly is provided with marker strips to identify the items in the file. The marker strips can be easily and legibly written on using a pencil or ballpoint pen. They are located immediately below the item they are to identify.

To aid in the discussion the rack assembly is broken into three sections: Input, Output and Monitoring section.



4.3.1 Input Section

The Input Section of the ASTC Rack Assembly supports a Cabinet Address Card, Bus Interface Unit, a combination of two & four channel devices, and a DC interconnect module. The types of input devices that can be inserted into the Input Files are two & four channel detectors (loop or magnetic), AC & DC isolators, and preemption modules. The input devices provide the BIU with information such as vehicle presence, AC & DC isolation, and DC interconnect signals.



Position assignments for the cabinet equipment are shown in Table 2:

Table 2. Cabinet Equipment Position Assignments

A Cabinet Address Card is provided in slot #1 and mates to a 22-pin dual readout edge connector whose numbered side is connected to the respective lettered side. This connector is offset vertically up by 0.1” from center to prevent the insertion of anything other than a Cabinet Address Card. The Cabinet Address Card is held firmly in the socket by a thumbscrew to prevent inadvertent removal. This module provides a means to hardcode a unique cabinet address to the cabinet.

The second slot connector mates with a Bus Interface Unit. This connector is a DIN 64-pin connector. This slot is hardcode to allow the BIU to operate as address #3. The BIU is responsible for generating all discrete Input/Output signal utilized in the cabinet. It provides interface and control between the ASTC controller and cabinet via SDLC communication. The signal assignment of the BIU when used in this slot is shown in Table 3:

Table 3. BIU Signal Assignment

Slot #3 to Slot #5 is a 22-pin dual-readout edge connector whose numbered side is connected to the respective lettered side. These slots are wired to accommodate both two- and four-channel devices. All appropriate signals are connected to these connectors to operate both DC and AC components.

Pins F and W on each connector connect to the proper BIU inputs on the motherboard. Output emitters, Pins H and X, are connected to logic ground. Pins D, E, J and K for each connector are hardwired to their appropriate field terminals FT3 and FT4.

Slot #6 is a 22-pin dual-readout edge connector whose numbered side is connected to the respective lettered side. This slot will accommodate a two-channel device or a DCI module.



4.3.2 Output Section

The Output section is capable of housing six Model 200 loadswitches, a Model 204 flasher unit, two Model 430 heavy duty relays (flash transfer relays), and four flash programming plugs. Together these components provides output load switching to traffic intersection signals.

Model 200 loadswitch DC trigger inputs and +24 volt DC is available on the backplane motherboard. These connector sockets are wired for the necessary power, inputs and outputs signals required to switch 120 VAC on and off to the intersection signal heads. Located on at the field terminal blocks for AC+, pedestrian and preempt commons, and loadswitch outputs.

The red and yellow signal circuits of the loadswitches are available on a Molex type receptacle which mates with a Molex type plug to allow flash programming. A plug connector, with programming jumpers, is furnished for each circuit to allow red and yellow flash programming. Plug pins are crimped and soldered.

Refer to the Output file interconnect schematic in this section during this discussion. The operation of the output section may be described as follows: AC+ supply for the loadswitches enters on the PDA#1 Harness from the PDA. Pin 1 provides power for Loadswitch #1. Pin 5 provides power to Loadswitch 4, and Loadswitch 6. Pin 11 provides power to Loadswitch 2 and Loadswitch 5. Pin 15 provides power to Loadswitch 3. Each of these power inputs are attached to circuit breakers in the Power Distribution Assembly. Each breaker independently provides 15 Amps of service power. Power for the Flasher Unit is available on Pin 9. The Flasher Unit outputs go to the flash transfer relays.

When the BIU issues a logic ground true loadswitch drive signal, the signal is routed to the individual loadswitch input. For example, loadswitch 1 Red receives a logic ground signal at Pin 6. Since the +24 VDC is supplied to Pin 9, current will flow in the loadswitch input circuit - specifically, the light emitting diode of an optical isolator. This turns on the output device causing current to flow from Pin 3 of the loadswitch to Pin 13 of the flash program block receptacle. Jumpers on the mating block then route the red signal through the flash transfer relay, and route the yellow signal directly to the field terminal. In the case of red flash programming, the program block ties Pin 13 to Pin 7 which connects to the normally open contact of FTR1, Pin 7. Therefore, the signal is routed through the relay common Pin 5, back through the program block to FT1 Position 1. In the de-energized state of FTR1 (flash mode), FT1-1B would connect through the program block and to the flasher output. Since the yellow signal is not required to flash in this instance, the program block routes this loadswitch signal directly to the output terminal block FT1. Note that the yellow and green signals are dark during flash operation due to the loss of AC+ on pin 1 of the loadswitch. The green signal does not flash; therefore, loadswitch 1 green connects directly to the output terminal block FT1 Position 3, bypassing the program block.

If yellow flash is required, the red flash program block is removed from its receptacle and interchanged with the yellow flash program block. In this configuration the red signal circuit is routed directly to its field terminal block, and the yellow signal is routed through the flash transfer relay contact to the output field terminal block.

A third type of program block is available for PED operation. Since flash operation is not required for PED phases, this program block routes loadswitch outputs directly to the field terminal blocks.



Note: The output section has 6 loadswitch positions. However, the rack assembly is designed with two Flash Transfer Relay and four programming block connectors. Subsequently, only the first four loadswitch may be programmed as described above.



4.3.3 Monitor Section

A Model 2010ASP monitor unit is connected to the motherboard through a rigidly supported printed circuit board edge connector. The connector has two rows of 28/56 independent double readout bifurcated contacts on 0.156 inch centers. All signals necessary for monitor operation are brought to this connector via PCB traces on the motherboard backplane.

It is possible to remove the monitor unit without causing the intersection to go into flash operation, but only while the cabinet door is open. The cabinet contains a conspicuous warning against operation with the monitor unit removed.

Power is connected to Pin FF (AC+) and Pin 21 (AC-) of the signal monitor edge connector. Additional signals brought into the monitor are those wired to monitor the appropriate field outputs. These are the yellow and green indications as well as PED Walk for purposes of conflict monitoring. The Conflict Monitor monitors the loadswitches as shown in Table 4:

Loadswitch CMU Channel

LS1 Ch. 1

LS2 Ch. 2

LS3 Ch. 3

LS4 Ch. 4

LS5 (W1) R,G Ch. 13R,G

LS6 (W2) R,G Ch. 14R,G

LS5 Yel * Ch. 13Y or Ch.15Y

LS6 Yel * Ch. 14Y or Ch.16Y

*Jumper programmable.

Table 4. CMU Channels Monitored

Two configuration jumpers are provided for the Yellow circuit on Loadswitch 5 and 6. Configuration jumper #1 allows for loadswitch 5 Yellow to be monitored on channel 13 yellow or channel 15 yellow. Configuration jumper #2 allows for loadswitch 6 Yellow to be monitored on channel 14 yellow or channel 16 yellow.

Additional signals such as WDT (Watch Dog Timer signal), +24 VDC monitor, DC stop timing output, DC ground, and external reset are signals that are involved with signal monitor activity.

A 20-conductor cable for monitoring the red outputs of all signal loadswitches is provided and attached to the rack assembly. The cable is routed from the front of the rack assembly and plugged into the connector provided on the front of the conflict monitor.

A mechanical jumper is provided to facilitate normal operation when a loadswitch position is unused. The mechanical jumper needs to be inserted into the unused loadswitch connector to short pins one and three. This will provide an AC+ signal to that channel’s red input to prevent the conflict monitor from registering a Red-Fail condition when that position is unused.



Red monitor disable control is provided on backplane motherboard. This relay is designated the red monitor (RM) control relay. The normally closed contacts provide 115 VAC to the red monitor select line on the monitor cable. When a logic ground signal is applied from pin B4 of the BIU connector, the RM relay energizes and opens the contacts removing the 115 VAC from the Red enable pin 20 of the red monitor cable. The relay power is derived from the cabinet +24 VDC cabinet supply.

A flash sense relay is mounted on the front of the rack assembly. The purpose of the flash sense relay is to determine the status of the current mode of operation with which the cabinet is in. The relay will be de-energized when the cabinet is in flash and thereby switch logic ground to the flash sense pin B24 of the BIU connector.



4.4 Miscellaneous Equipment



4.4.1 Cabinet Address Card

A Cabinet Address Card (CAC) is used to assign a unique 16-bit address to each cabinet. The CAC module is a plug-in type circuit board with an edge card type connector on one end and a panel and extractor handle on the other end. The board dimensions are 4.5” high by 6.9” deep with a panel dimension of 4.5” high by 2.24” wide. This module contains a matrix of 20 diodes that can be configured to create a four digit Hexadecimal cabinet address. In addition, the front panel holds the test switches for the Stop Time and Min Recall functions. The card is fastened to the rack in order to prevent the card from being casually removed.

The CAC is configured by removing diodes in relation to Table 5. The transmission of the cabinet address utilizes an odd parity communication technique, therefore a parity bit must also be accounted for. Table 5 shows Hexadecimal to Binary conversion using odd parity:



Hex Binary Parity Bit Needed? Result

0 0000 Y 10000

1 0001 N 00001

2 0010 N 00010

3 0011 Y 10011

4 0100 N 00100

5 0101 Y 10101

6 0110 Y 10110

7 0111 N 00111

8 1000 N 01000

9 1001 Y 11001

A 1010 Y 11010

B 1011 N 01011

C 1100 Y 11100

D 1101 N 01101

E 1110 N 01110

F 1111 Y 11111

Table 5. Hex to Binary Conversion Using Odd Parity

Odd parity requires that a 4-bit binary number have an odd number of 1s. If a binary number has an even number of 1s (or none at all), a parity bit is added before the MSB to make the number of 1s be odd.

The binary numbers are decoded this way: PB/MSB/b/b/LSB, where PB=parity bit, M=MSB of the 4-bit number, b=less significant bit, and L=LSB of the 4-bit number. A parity bit is only added if the number of binary 1s in a 4-bit number is even (or zero).

For example, 0, represented in binary as 0000, has no 1s (see Table 5). Therefore a parity bit is added. One, represented in binary as 0001, has an odd number of 1s, so no parity bit is needed. The same is true for 2. However, 3, represented in binary as 0011, has an even number of 1s, so a parity bit is added to make an odd number of 1s, hence 10011.



The formats for the different addressing schemes for New York City are as follows:

For Manhattan Coaxial Cable connected controllers: 00.x.CCCCC.AAAAAAAA

00 indicates that this controller is connected to the Manhattan Cable RF System. x is unused for this group CCCCC – is the Manhattan channel number (1-32) AAAAAAAA – forms a unique 8 bit address (1-240)

*Note that the channel number and address create a unique cabinet number (7680 possible).

For Outer Boroughs (100 VDC Interconnect) connected controllers: 01.LLLLLL.LLLLLLLL

01 indicates that this is an outer boroughs cabinet connected via DC control. As a result, it will expect the HOL, ADV, FADV, RESYN signals to be computed from the signals at the BIU inputs and will drive the BIU functions to transmit the CHECK and MSG functions. L…L forms a unique 14-bit cabinet address (16,384) which is used for database validation purposes. This type of communications connection does not support data exchange.

For NTCIP connected controllers: 1.PP.AAAAAAA.NNNNNN

1 indicates that this cabinet will use its serial data Port to communicate with the central computer using the NTCIP protocol. The NTCIP protocol conforms to NEMA TS2-1998, Section 3.3.6 for Actuated Type 1 (A1N Level 2) and Pretimed Type 1 (P1N Level 2) controllers. PP bits are used to identify the type of communications to be supported. This allows for a maximum of 4 configurations with 8192 controllers using each configuration. For TOPICS IV ‘00’ denotes 9600 bits-per-second serial communications. The other three settings (‘01’, ‘10’, ‘11’) are yet to be determined. A..A is concatenated with the NTCIP address to form a unique cabinet address for this communications configuration (8192) N…N bits are used for the NTCIP 6 bit (short) address as required in NEMA TS3.3-1996 Section 3.3.3.1 Figure 3-3.



4.4.2 Port-1 Harness

The ASTC cabinet is provided with a communication harness to interconnect the controller’s Port 1 signals to the BIU and to the transient protection/expansion assembly. Each harness provides a twisted pair for the TX Data, TX Clock, RX Data, and RX Clock Signals. The harness’s connector is a 15-pin D subminiature type and has spring latches to ensure proper mating. The pin assignments are shown in Table 6.

4.4.3 P20 Red Monitor Cable

The P20 Red Monitor Cable is a 20-position ribbon cable with two Insulation Displacement Connectors on each ends for mating with a 2010ASP-NYC front panel connector. The cable routes the Field wire Red signals to the associated Conflict Monitor channel’s red signal inputs. In addition to the Red Signal inputs, there is a Red Enable input that activates the plus features of the monitor (refer to 2010ASP-NYC Manual). Table 7 shows the Red Interface cable pin assignments:

2. Place the ASTC Controller onto the top shelf of the rack assembly. Plug the controller power cord into the controller receptacle in the header assembly. Connect the SDLC communication cable to the Controller’s Port 1 connector. The SDLC cable needs to be properly connected to the ASTC Controller, the Bus Interface Unit, and the Termination Protection Board. Ensure the connector clips on the communication cable properly latch on to the locking blocks.

3. Signal light connections are made to terminal blocks FT1 and FT2. Refer to the cabinet print provided with and located in the cabinet for terminal block position assignments.

4, The Detector input connections are made directly to terminal blocks FT3 and FT4. In addition to the vehicle loop detector connections, ensure any necessary pedestrian inputs or preempt inputs are connected to the appropriate positions.

Note: The AC– buss bar can be used as the reference for the pedestrian and preempt inputs.

5. Disconnect the Red Interface cable from the Model 2010ASP Conflict Monitor and remove the unit from the rack assembly. Program the appropriate dipswitch settings (refer to 2010ASP/2010ASP-NYC Conflict Monitor Technical Manual MN078135 for dipswitch settings details). Reinsert the Conflict Monitor. Remove the programming card from the Conflict Monitor and program the conflicts to be ignored by removing the appropriate diodes as marked. Solder the jumpers for those channels where yellow light monitoring is to be inhibited. Reinsert the programming card into the Conflict Monitor.

6. Connect the communication system: a. If using the Manhattan RCU (MRCU), install it by placing it onto the top shelf next to

the ASTC Controller as shown in Section 8.3. Connect power cable (part number H80033) from P1 to the Cabinet Controller Receptacle on the cabinet header assembly. Attach two RCU Coax Cables (part number 2-00455-01) to the VIDT mounted on the front lower left of the ASTC Cabinet. Attach an RCU Communica-tion Adapter and Cable (part number H80034.01) from the RCU RS-232 port to Port 2 on the ASTC Controller. Turn RCU ON switch on.

b. If using the Outer Boroughs DCI module, install it into the right-most slot of the top rack, above the loadswitches and below the ASTC Controller as shown in Section 8.3. Connect jumper wires between Field Input Terminal Block pins FT4-1 (Tip) and FT4-2 (Ring) to the appropriate Tip and Ring connectors on the Cabinet Demarca-tion Terminal Block.

7. The ASTC Rack Assembly provides four flash programming jumper plugs for selecting Red or Yellow flash. Insert the red or yellow Molex plugs, depending on the type of flashing desired.



8. Turn on all circuit breakers. For normal three-color operation, check that the Signal AUTO/FLASH switch is in the AUTO position and that the Signal ON/OFF switch is in the ON position.

Cabinet Maintenance ASTC-6 Cabinet - Technical Manual


6.1 Preventive Maintenance The ASTC Cabinets are designed to require minimum maintenance; however, certain simple steps should be taken to insure proper operation, such as periodically checking the air filter and replacing it if necessary and checking wiring, terminals, and connectors for signs of breakage and wear and repairing or replacing if necessary. Housekeeping steps such as vacuuming dust and cleaning the interior of the cabinet are valuable steps in maintaining good air circulation.

It is recommended that the ASTC cabinet be checked at 6 months after installation and at least annually thereafter. After the initial check, a regular interval for preventive maintenance may be established based on the condition. Some locations may need attention more often than others depending on the environment in which they were installed.

The following maintenance procedures should be performed on a regular basis:

• Replace air filters.

• Check operation of fan assembly for proper operation to ensure adequate ventilation.

• Lubricate lock and three point locking mechanism.

• Check all wiring connections for tightness, corrosion, damaged insulation, etc.

• Check all equipment connections for corrosion, contamination, and damage, making sure they are properly seated.

• Check all mounting hardware for proper tightness.

• Check the integrity of all PDA harness connections and equipment ground bars.

• Vacuum dust and clean cabinet interior

Systematic evaluation of the 2010ASP-NYC Monitor Unit is necessary in determining safe system operation. The monitor may be removed and fully tested, then reinstalled and observed for proper channel operation.
