40 Installation Guidelines for Spark-Ignited Stationary Emergency Generators
5. Press MANUAL on the control panel keypad. The engine should crank and start immediately.
6. Allow the engine to warm up for a few minutes.
7. Move the Main Circuit Breaker switch on the generator control panel up to the ON (Closed) position. Loads are
now powered by the standby generator.
8. Turn ON the circuit breaker/electrical loads powered by the generator.
9. Connect a calibrated AC voltmeter and a frequency meter across terminal lugs E1, E2, and E3 (if three phase).
Voltage should be approximately unit rated voltage.
10. Let the generator run at full rated load for 20-30 minutes. Listen for unusual noises, vibration or other indications
of abnormal operation. Check for oil leaks, evidence of overheating, etc.
11. When testing under load is complete, turn OFF electrical loads.
12. Move the Main Circuit Breaker switch on the generator control panel down to the OFF (Open) position.
13. Allow the engine to run at no-load for 2-5 minutes.
14. Press OFF on the control panel keypad to shut the engine down.
6.12.5— Check Automatic Operation
To check the system for proper automatic operation, proceed as follows:
1. Verify that the generator is OFF. A red LED above OFF on the control panel keypad illuminates to confirm that
the system is in the OFF mode.
2. Install front cover over the transfer switch.
3. Turn ON the utility power supply to the transfer switch, using the means provided (such as a utility main line cir-
cuit breaker).
NOTE: Transfer Switch will transfer back to utility position.
4. Move the Main Circuit Breaker switch on the generator control panel up to the ON (Closed) position.
5. Press AUTO on the control panel keypad. The system is now ready for automatic operation.
6. Turn OFF the utility power supply to the transfer switch.
With the generator ready for automatic operation, the engine will crank and start when the utility source power is turned
OFF after a 10 second delay (factory default setting). After starting, the transfer switch connects load circuits to the
standby side. Let the system operate through its entire automatic sequence of operation.
With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer
switch. The system transfers back to the utility position and then runs through the cool down cycle and shuts down.
6.13 — Installation Summary
1. Ensure that the installation has been properly performed as outlined by the manufacturer and that it meets all
applicable laws and codes.
2. Test and confirm proper operation of the system as outlined in the appropriate installation and owner’s manuals.
3. Educate the customer on the proper operation, maintenance and service call procedures.
IMPORTANT! If the customer ever finds it necessary to turn the generator off during prolonged utility outages
to conserve fuel or perform maintenance, alert them to these important steps:
To turn the generator OFF (while running in AUTO and online):
1. Turn OFF (or open) the main Utility disconnect.
2. Move the Main Circuit Breaker switch on the generator control panel down to the OFF (Open) position.
3. Press OFF on the control panel keypad. A red LED illuminates to confirm that the system is in the OFF mode.
To turn the generator back ON:
1. Press AUTO on the control panel keypad. Allow the unit to start and warm up for a few minutes.
2. Move the Main Circuit Breaker switch on the generator control panel up to the ON (Closed) position.
The system is now operating in the automatic mode. The main utility disconnect can be turned ON (Closed), but to shut
the unit off, this complete process must be repeated.
