INSTALLATION
The 2018KCL 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 2018KCL with the adapter
PCB, insert the Interconnecting cable plug into the Red Interface connector (P1) 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 P1
correspond to Red channel 1:16 inputs on the 2018KCL. Channel 17 and 18 Red inputs are
provided on the main connector (P6). Pin #20 of P1 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 (SF1,2)
The pins numbered 8 and 6 of Red Interface connector P1 are Special Function (SF) inputs
#1 and #2 respectively. These inputs require an AC+ input to disable the Red Failure
monitoring function during preemption. An active signal on
either
input will disable Red
Failure monitoring. The RED FAIL indicator will then flash once every two seconds to
indicate that Red Failure monitoring is disabled.
The Special Function #1 Invert option may be used to change the polarity of the Special
Function input #1 (see section 4.2.3.10). When the option is not selected, the Special
Function input #1 will be active when AC+ is present. AC+ present on
either
input will
disable Red Failure monitoring. An unused preemption input may be left OPEN (no
connection) if the option is not selected. When the Special Function #1 Invert option is
selected, the Special Function input #1 will be active when AC+ is NOT present. Lack of
AC+ on Special Function #1 input will then disable Red Failure monitoring.
