7.7 CHECKING
AUTOMATIC
OPERATION
To check the system for proper automatic operation, proceed as follows:
1. Ensure that the generator is OFF.
2. Install front cover of the transfer switch.
3. Turn ON the utility power supply to the transfer switch, using the means provided (such as a utility main line circuit breaker).
NOTE: Transfer Switch will transfer back to utility position.
4. Set the generator’s main circuit breaker to its ON (or CLOSED) position.
5. Push the generator’s AUTO button. 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 should crank and start when the utility source power is turned OFF after a 10 second
delay (factory default setting). After starting, the transfer switch should connect load circuits to the standby side after a fi ve (5) second delay. 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 following should
occur:
• After approximately 15 seconds, the switch should transfer loads back to the utility power source.
• Approximately one minute after re-transfer, the engine should shut down.
NOTE: 50Hz generators do not have the quiet test function.
7.8 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 confi rm proper operation of the system as outlined in the appropriate installation and owner’s manuals.
3. Educate the end-user on the proper operation, maintenance and service call procedures.
Important! If the end user ever finds it necessary to turn the generator off during prolonged utility outages to per-
form maintenance or conserve fuel, educate them on these simple, but important steps:
To turn the generator OFF (while running in AUTO and online):
1. Turn OFF (or OPEN) the main Utility disconnect.
2. Turn OFF (or OPEN) the Main Line Circuit Breaker (MLCB) on the generator.
3. Turn the generator OFF.
To turn the generator back ON:
1. Put the generator back into AUTO and allow to start and warm-up for a few minutes.
2. Turn ON (or CLOSE) the MLCB on the generator.
The system will now be operating in its automatic mode. The main utility disconnect can be turned ON (or CLOSED), but to shut the unit off, this
complete process must be repeated.
