4.3.3 CONTACTOR CYCLE COUNTER (CM 2000+ ONLY)
Purpose: This feature indicates the total number of off-to-on transitions a contactor has made
since the last time the CONTACTOR CYCLE COUNTER was reset. This serves as a method
to perform preventative maintenance on the contactor according to the manufacturer’s
specifications. This count value is written to the control module’s non-volatile memory once
every 24 hours or whenever the user resets any maintenance data.
Procedure: The CONTACTOR CYCLE COUNTER may be reset to zero using an external
upstream programming device. See the appropriate manual for the proper procedure.
IMPORTANT:
• Once the CONTACTOR CYCLE COUNTER reaches 999,999,999 it will stop counting.
• The CONTACTOR CYCLE COUNTER is only indicated if the SWITCH CONTROL MODE is set
to either DEADBAND or PROPORTIONAL AMBIENT CONTACTOR.
4.3.4 TIME IN USE
Purpose: The purpose of this feature is to indicate the total hours the control module has been
in use since its initial operation. It may be useful to log the amount of time a particular control
module has been in operation for the purposes of maintenance planning or reliability testing.
The value of this accumulator is written to the control module’s non-volatile memory once
every 24 hours or whenever the user resets any maintenance data.
Procedure: The IN USE hours accumulator can be reset to zero using an external upstream
programming device. See the appropriate manual for the proper procedure.
IMPORTANT: The IN USE hours accumulator value will roll over to zero when the upper limit of
the accumulator has been exceeded. This upper limit for the CM 2000+ is 999,999,999 hours
and the upper limit for the CM 2000 is 16,777,215 hours.
4.3.5 TIME SINCE LAST RESET
Purpose: This feature indicates the total hours the control module has been in use since
the last reset. For trouble-shooting purposes, it may be useful to log the amount of time a
particular control module has been in operation since the last time the control module’s power
was cycled.
Procedure: The TIME SINCE LAST RESET hours accumulator can only be reset by cycling the
control module’s power.
IMPORTANT: The TIME SINCE LAST RESET hours will roll over to zero when the upper limit of
65,535 hours has been exceeded.
