Checking Automatic Operation; Installation Summary; Shutting Generator Down While Under Load; Testing The Smart A/C Module - Generac Power Systems RTG24SHA1 Owner's Manual

• Verify that the gas pressure remains within
acceptable parameters (see the generator
Installation Guidelines manual).
• 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 test 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. Operating lever of
transfer switch should be in UP position.
9. Install front cover of enclosure.
10. 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.

Checking Automatic Operation

To check the system for proper automatic operation,
proceed as follows:
1. Verify generator is in OFF mode.
2. Set the generator main circuit breaker to ON.
3. On the generator panel, select AUTO. The system
is now ready for automatic operation.
4. Turn utility power supply to the transfer switch OFF
with the Utility Breaker.
With the generator ready for automatic operation, and the
utility source power turned off, the engine should crank
and start 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
warmup delay. Timer duration varies depending on
whether or not Cold Smart Start (if equipped) is enabled.
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.
Automatic Transfer Switch Owner's Manual

Installation Summary

1. Verify the installation has been properly performed
as outlined by the manufacturer and that it meets
all applicable laws and codes.
2. Verify 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.
Shutting Generator Down While
Under Load
IMPORTANT NOTE: To avoid equipment damage, follow
these steps, in order, when shutting the generator down
during utility outages. Shutdowns may be required during
outages to perform routine maintenance or to conserve fuel.
To turn the generator OFF (while running in AUTO
and online):
1. Turn main utility disconnect off.
2. Turn the generator MLCB (generator disconnect)
to OFF (open).
3. Run generator for approximately one minute to
allow proper cooling.
4. Turn the generator OFF.
To turn the generator back ON:
1. Place generator in AUTO mode. Start generator
and warm up for a few minutes.
2. Set MLCB (generator disconnect) to ON (closed).
The system now operates in automatic mode. Main utility
disconnect can be turned ON (closed). To shut the unit
off, repeat the entire process.

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.
