TS 910 TRANSFER SWITCH
PM140 REV 2 14/01/23 42 Thomson Power Systems
LED OFF - Exercise Timer is not initiated and the 7, 14 or 28 day cycle
timer is not active.
To terminate the Generator Exercise Mode, the Exercise pushbutton must be
held on for 2 seconds until the LED light above the pushbutton starts flashing.
When the pushbutton is released, the LED light will go out and the system will
return to normal operation.
NOTE
When the Exercise Test is first enabled, do not cancel the test until the Genset
has started and has transferred on load for at least 60 seconds. If the Test is
cancelled before 60 seconds has expired, the fail to exerciser alarm will be
triggered and the Genset will not correctly exercise automatically in the future
until the alarm is reset.
18.9.3 REMOTE TEST
To activate a remote load test, a contact is to be remotely closed between
terminal #7 and terminal #8 on the Customer Interface Terminal Block. When the
contact closes, and generator start will be activated and once the generator
accelerates to nominal voltage and frequency levels, the load will automatically
transfer to the generator supply. When the remote contact is opened, the load
will re-transfer back to the utility supply following expiry of the Utility Return delay
timer. The Engine Cool down time sequence will be initiated when the test mode
is terminated.
NOTE
The load will automatically re-transfer to the utility supply should the generator
fail while on load.
18.10 TRANSFER FAIL FAULT RESET
To reset a Transfer Fail condition (i.e. When either the Load on Gen or Load on Utility
Lights are flashing and the ATS load is transferred to the alternate source), both
faceplate pushbuttons (i.e. TEST & EXERCISE) must be held on for 10 seconds until all
Lights on the faceplate start flashing. Once the alarm condition is reset, the load will
automatically retransfer back to the original source if within normal limits.
