Generac Power Systems RTSW100A3 Owner's Manual page 15

• Let the generator run under rated load for at least 30
minutes. With unit running, listen for unusual noises,
vibration, overheating, etc., that might indicate a
problem.
6. When checkout under load is complete, set main
circuit breaker of the generator to the OFF or
OPEN position.
7. Let the generator run at no-load for several
minutes. Then, shut down by selecting the OFF
mode.
8. Move the main switch contacts back to the utility
position.
NOTE: See "Manual Operation". Handle and operating
lever of transfer switch should be in down position.
9. Turn on the utility power supply to transfer switch,
using whatever means provided (such as a utility
main line circuit breaker). The utility power source
now powers the loads.
10. The system is now set for fully automatic operation.
Checking Automatic Operation
To check the system for proper automatic operation,
proceed as follows:
1. Verify generator is in OFF mode.
2. Verify switch is de-energized.
3. Install front cover of the transfer switch.
4. Turn the utility power supply to the transfer switch
ON, using the utility main line circuit breaker.
5. Set the generator main circuit breaker to ON.
6. On the generator panel, select AUTO. The system
is now ready for automatic operation.
7. Turn utility power supply to the transfer switch OFF.
With the generator ready for automatic operation, the
engine should crank and start when the utility source
power is turned OFF after a ten second delay (factory
default setting). After starting, the transfer switch should
connect load circuits to the standby side after a five (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.
With the generator in the AUTOMATIC mode, the system
is now set for fully automatic operation.

Shutting Generator Down While
Under Load
Important! To turn the generator off during utility outages
to perform maintenance, or conserve fuel, follow these
steps:
To turn the generator OFF (while running in AUTO and
online):
1. Turn the main utility disconnect OFF.
2. Turn the main line circuit breaker (MLCB) on the
generator to OFF (OPEN).
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. Set the MLCB on the generator to ON.
The system will now be operating in automatic mode.
The main utility disconnect can be turned ON (CLOSED).
If Utility returns, the transfer switch will return to utility
mode and the generator will cycle off after it times out.
Testing The Smart A/C Module
A Test pushbutton is provided on the bottom of the Smart
A/C Module to test the operation of the load shed
functions. The Test button will work when the ATS is in
the Utility or the Generator position.
1. Turn on the Utility supply to the ATS.
2. Verify managed loads are powered and all LEDs
illuminate on Smart A/C Module.
3. Press the TEST button on the Smart A/C Module.
4. Verify that all of the connected loads to be "shed"
become disabled.
5. After five (5) minutes verify A/C 1 is energized and
Status LED A/C 1 is ON.
6. After another 15 seconds, verify A/C 2 is energized
and Status LED A/C 2 is ON.
7. After another 15 seconds, verify Load A/C 3 is
energized and Status LED Load A/C 3 is ON.
8. After another 15 seconds, verify A/C 4 is energized
and Status LED A/C 4 is ON.
