TS 910 TRANSFER SWITCH
PM140 REV 0 12/02/09 39 Thomson Technology
LED FLASHING - Exercise Timer is initiated, the 30 minute run timer is
active and the generator is running on load.
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.
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.
18.11. LAMP TEST
To initiate a Lamp Test, both faceplate pushbuttons (i.e. TEST & EXERCISE) must be
held on longer than 5 seconds until all Lights on the faceplate illuminate in a flashing
mode.
