INSTALLATION
The Signal Monitor is a plug-in module for the Type 170/179 output file. When inserted into
the output file without the Red Interface cable assembly, it will operate as a standard 210
Signal Monitor.
4.1 ADAPTING RED MONITORING
A Red Interface Adapter PCB and an Interconnecting cable are used to adapt Red Signal
Monitoring to the controller cabinet assembly. The interconnecting cable is terminated at
each end with identically polarized 20 pin plugs. To connect the Signal Monitor with the
adapter PCB, insert the Interconnecting cable plug into the Red Interface connector (P8) until
the two ejector latches "snap" into place over the cable plugs.
4.1.1 RED FIELD INPUTS
The pins numbered 1,2,3,5,7, and 9 through 19 of the Red Interface connector P8 correspond
to Red channel inputs on the Signal Monitor.
All unused Red channel inputs must be
terminated to AC+.
Pin #20 of P8 is the Red Enable input and must be active to enable Red
Failure Monitoring, GYR-Dual Indication Monitoring, and Clearance Monitoring. The Red
Enable input is normally connected to the load switch AC+ buss in order to disable Red
Failure Monitoring, GYR-Dual Indication Monitoring, and Clearance Monitoring when the
intersection is in hardware flash.
4.1.2 SPECIAL FUNCTION PREEMPT INPUTS (SF1, SF2)
The pins numbered 8 and 6 of Red Interface connector P8 are Special Function (SF) inputs
#1 and #2 respectively.
NYCDOT
: These inputs do not provide the conventional Red Fail override, they only report
status to the CU via the serial protocol.
4.2 SSM SWITCH PROGRAMMING
The SSM dip switches (SW4, SW5) are located near the program card edge connector. The
switch positions are labeled CH1 to CH16 (CH18) on the PCB legend screen, corresponding
to channels 1 through 16 (18), respectively. To enable GYR-Dual Indication
and
Clearance
Monitoring on a channel, place the corresponding channel dip switch to the ON position.
Disabling Yellow input sensing on the program card will also disable GY-Dual Indication, YR-
Dual Indication and Clearance Monitoring for that channel regardless of the dip switch
position for that channel.
The corresponding channel SSM dip switch must be placed in
the OFF position when an unused Red field output terminal on the adapter PCB is
connected to AC+.
4.3 PROGRAM CARD PROGRAMMING
The diode Program Card provides the means to assign non-conflicting channels and to
disable sensing of Yellow input signals. The card is initially supplied with 120 (2018ECL has
153) diodes mounted on the card. This permits all channels to conflict with all other channels.
- WARNING -
THE P8 RED INTERFACE CABLE SHOULD ALWAYS BE UNPLUGGED BEFORE
REMOVING THE UNIT FROM THE CABINET TO PREVENT POTENTIAL
EXPOSURE TO ELECTRICAL SHOCK.
