signal from an external crossing controller or the corresponding SSCC-(#) of an intercon-
nected adjacent crossing.
If the input is low SSCC-1 and SSCC-2 will activate, flash lamps, and drop gates.
NOTE
If no health output is available from the external equipment, Aux-(1) Xng
Ctrl Hlth still must be assigned to a physical input and strapped high.
4.11.5 Crossing Controller Gate Position Configuration Examples
Five examples are provided to show how to use the GP and GP Coupled status fields:
Example 1 – One Gate position input
Example 2 – Two gate position inputs
Example 3 – Single gate position input to each crossing controller
Example 4 – Single gate position input to each crossing controller with independent gate position
Example 5 – Crossing flashers only
4.11.5.1 Example 1 - Crossing Configured With One GP Input
In the SSCC Configuration window set
SSCC1+2 GP Coupled
to
Yes
. This will cause the
lamps on both crossing controllers to flash if the GP input goes low
In the SSCC 1 Configuration window set
SSCC-1 Number of GPs
to 1 (default)
In the SSCC 2 Configuration window set
SSCC-2 Number of GPs
to 0 (default)
4.11.5.2 Example 2 - Crossing Configured With Two GP Inputs
To configure the crossing to respond to two gate position (GP) inputs to the same crossing
controller (this allows both gates to have their GPs wired individually to two SSCC GP inputs):
Set
GP Coupled
of the
SSCC
window to
Yes.
This causes the lamps on both crossing controllers to flash if either GP input goes low.
Set the parameters for each crossing controller. The two GP inputs are automatically combined
internally, which allows the SEAR to independently monitor each gate position input.
Set the inputs to the crossing controllers.
The gate position wires are connected to IN 7.3 and IN 7.5 of SSCC-1.
