Figure 4-15 External Crossing Controller IO Assignment

To sync the lamps on the external controller:
•
Connect the flash sync output of the GCE to the flash sync I/O of the external
crossing controller as follows:
•
Connect the FLASH SYNC + output of the GCE chassis to the FLASH SYNC I/O on
the external crossing controller.
•
Connect the FLASH SYNC - output of the GCE to N of the external crossing
controller. (The power returns for the GCE and the external crossing controller do not
have to be connected.)
•
When used, connect MAINT CALL of the GCE with MAINT CALL of the external
crossing controller as described in paragraph 6.12.
SSCC IIIi Modules Rev D and later have an isolated flash sync output.
Where battery isolation must be maintained and SSCC IIIi Modules of
Rev C or earlier are used, contact Siemens Technical Support for
application information.
The Aux-1 Lmp Control output de-energizes whenever the lamps on
SSCC-1 flash, either due to activation, gate position, or SSCC health.
If the external controller fails, its gate output will de-energize, causing the
Aux-1 Xng Ctrl Hlth to de-energize and the internal crossing controllers to
activate.
