STOP CONTACTS OPEN

Whenever a shutdown occurs, the K1 relay de-energiz-
es and the contacts open on the Logic/Trigger Board.
If the K1 contacts open, and no fault is detected in the
serial communications link, then a Cycling shutdown
will occur.
The shutdown message displayed will be "LCSSS -
STOP CONTACTS OPEN".
Possible Problems
• Verify that the J1 connector is installed on the
Logic/Trigger Board, and that there is a wire in-
stalled between J1-11 and J1-12.
• Verify that TB1-1 and TB1-2 are properly wired.
JOHNSON CONTROLS
SECTION 5 – CYCLING SHUTDOWNS
• Verify the communication cable between the
OptiView Control Center and the Logic/Trigger
Board.
• Verify operation of the K1 relay. If the function
of K1 is not working properly, replace the Logic/
Trigger Board.
• If CR6 is blinking, but CR7 is not blinking, the
Logic/Trigger Board has failed. If both CR6 and
CR7 are blinking every two seconds, continue to
the next step.
• If problem is still not detected, then perform the
communication loop back test (ASSOCIATED
LITERATURE listed on page 3 for OptiView
Control Center Service).
