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, Generator and loads can be energized in a safe manner.
2.
3. Verify the status of the following indicator lights on the TSC 9 HMI faceplate:
- Utility Source Green light is “ON”
- Load on Utility Green light is “ON”
4. Run the generator manually and confirm generator supply voltage
.
5. Verify the status of the following indicator lights on the TSC 9 HMI faceplate:
- Generator Source Red Light is “ON”
6. Using appropriate personal protective equipment (PPE) and insulated tools/meters, remove the transfer switch front cover
while energized.
7. Verify at the transfer switch (while energized), the utility and generator supply voltage, phasing and phase rotation is correct.
8. Manually stop generator and place the generator controls in the "AUTOMATIC" position.
9. To confirm automatic starting and load transferring of the generator, perform the following steps:
a) To test, press and hold the “T” pushbutton on the TSC 9 controller faceplate for 2 seconds until light above
pushbutton comes ON. The generator will start and transfer on load per Automatic Sequence.
b) To determine correct operation, observe the following on the TSC 9 faceplate:
- Gen Start Red light is “ON”
- Gen Source Red light is “ON”
- Load on Gen Red light is “ON
10. To stop the generator and transfer load back to the utility supply, press and hold the “T” pushbutton for 2 seconds until light
above pushbutton goes OFF. The load will re-transfer back to the utility power as per Automatic Sequence.
11. Perform a utility power outage test by opening the upstream utility feeder breaker. The TSC 9 controller Utility supply light will
turn off; the generator set will start after the 3-second engine start delay has expired, the generator should start and transfer
on load as per Automatic Sequence.
12. 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.
