TEST : (Full load test) A primary source failure is simulated and an engine
start signal will be initiated. When the secondary source is within
normal limits, the TSC 80 will initiate a transfer to the secondary
source. The system will remain in this state until the FTS4 is placed
in another position or the secondary supply fails. Upon a secondary
supply failure, if the primary supply is available, the TSC 80 will
initiate a transfer to the primary supply. The Engine Cooldown time
sequence will be initiated when the test mode is terminated.
3.2.4. REMOTE TEST
To activate a remote load test, a contact is to be remotely closed between terminal #44
and terminal #38. When the contact closes, and engine start will be activated and once
the engine 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 Cooldown 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.
3.3. TRANSFER FAIL FAULT RESET
To reset a Transfer Fail condition (i.e. When either the Load on Gen or Load on Utility
LEDs are flashing and the ATS load is transferred to the alternate source), both Lexan
faceplate pushbuttons (i.e. UTILITY POWER FAIL SIMULATE & GENERATOR
EXERCISE MODE) must be held on for approximately 5 seconds until all LEDs on the
Lexan start flashing and UTILITY POWER FAIL SIMULATE LED flashes in opposition.
Once the alarm condition is reset, the load will automatically retransfer back to the
original source if within normal limits.
3.4. LAMP TEST
To initiate a Lamp Test, both Lexan faceplate pushbuttons (i.e. UTILITY POWER FAIL
SIMULATE & GENERATOR EXERCISE MODE) must be held on longer than 5
seconds until all LEDs on the Lexan illuminate in a flashing mode.
