Installation
5.1 PERMISSIVE CHANNEL PROGRAMMING
The SSM-LE Series
Program Card contains a group of soldered wire jumper holes to set
the permissive or compatible channel configuration. This programming is determined by the
intersection layout and phase assignments. The card is initially supplied with 66 empty wire
jumper hole pairs. This initial programming sets all channels to conflict with all other
channels. To program a compatible channel pair, solder a wire jumper into the appropriate
location for that channel pair as marked on the Program Card.
Make sure that any jumper
leads do not make contact with any other jumper lead on the card or the monitor
chassis when the Programming Card is inserted into the unit.
Example: If channel 2 Green and Yellow is
PERMISSIVE
with channel 6 Green and Yellow,
solder a jumper wire into the jumper pair labeled "2-6".
If the Program Card is absent or not seated properly in the edge connector, the SSM-LE
Series
will enter the fault mode, transfer the OUTPUT relay contacts to the Fault position,
and display the PROGRAM CARD status screen. The SSM-LE Series
will remain in the
fault mode until the Program Card is correctly seated and the SSM-LE Series
is reset by
the RESET button or the EXTERNAL RESET input.
5.2 MINIMUM FLASH TIME PROGRAMMING
It is recommended that the Minimum Flash Time be programmed on the SSM-LE Series
to
facilitate an orderly start-up sequence of the Cabinet Assembly upon application or
restoration of AC LINE power. The Minimum Flash Time should be long enough to ensure
all cabinet components are initialized and ready before the SSM-LE Series
transfers the
OUTPUT relay and places the intersection into signal operation.
Programming of the front panel Minimum Flash DIP switches is in a binary encoded format:
MinFlash 8
MinFlash 4
MinFlash 2

5.3 SSM SWITCH PROGRAMMING
The SSM switches on the SSM-LE series Signal Monitor are labeled "1" to "12" ("6")
corresponding to channels 1 through 12 (6), respectively. Positioning a switch in the ON
position (to the right) enables a channel for Dual Indication
AND
Clearance Monitoring.
