b. Equipment Energization
DANGER
HAZARD OF ELECTRICAL SHOCK, EXPLOSION, OR ARC FLASH
•This equipment must be serviced only by qualified electrical personnel utilizing safe work practices and appropriate Personal
Protective Equipment (PPE).
•Many components of this equipment operate at line voltage. DO NOT TOUCH. Use only electrically isolated tools.
Failure to do so may cause personal injury or death
1. Confirm Utility source and loads can be energized in a safe manner.
2. Energize utility supply and confirm voltage is correct as configured and phase rotation at the utility and load is correct.
3. Energize the 24Vdc nominal control power and ensure the ATS controller powers up.
4. Verify the status of the following indicator lights on the ATS Controller:
- Utility Source Available indicator light is illuminated
- Load on Utility indicator light is illuminated
5. Confirm Generator source can be energized in a safe manner.
6. Open local main generator breaker and start the generator manually from the local control panel and confirm the generator set operates
correctly and the generator supply voltage matches the ATS voltage rating.
7. Stop the generator and close its main output circuit breaker
8. Re-start the generator manually and using appropriate personal protective equipment (PPE) and insulated tools/meters, open the transfer
switch door while energized and verify at the transfer switch mechanism, the generator supply voltage, phasing and phase rotation is correct
(i.e. matches the Utility supply). Once verified, re-close ATS enclosure door.
NOTE
On 3 Phase Systems, the ComAP ATS controller has Phase Rotation miss-match protection. For the ATS to successfully transfer
between sources, both the Utility and Generator Source Phase rotation must be matched. Phase rotation on both sources can be
either positive rotation (i.e. A-B-C) or negative rotation (C-B-A)
9. Verify the Generator Source Available indicator light is illuminated on the ATS Controller.
10. Manually stop generator and place the local generator control panel to the "AUTOMATIC" position.
11. To confirm automatic starting and load transferring of the generator, perform the following steps:
a) To test, change the operating mode of the ATS Controller to “TEST” Mode. The generator should start and transfer
on load per Automatic Sequence provided an on-load test is called for.
b) Verify the following ATS Controller indicator lights are activated:
-Generator Source Available indicator light is illuminated
-Load on generator indicator light is illuminated
12. To stop the generator and transfer load back to the utility supply, return the ATS Controller back to the AUTO mode. The load
will re-transfer back to the utility power as per Automatic Sequence.
13. Perform a utility power outage test by opening the upstream utility feeder breaker. The ATS controller will signal an abnormal
utility voltage condition and the generator set will start after the engine start delay has expired. Once started, the generator set
should start and transfer on load as per Automatic Sequence.
14. Return the transfer switch to utility power by re-closing the upstream utility breaker. The load should re-transfer back to the
utility supply as per Automatic Sequence.
