instructions to adjust the generator set. The
automatic transfer switch will only function with
the rated system voltage and frequency
specified on the nameplate.
4. Use a phase rotation meter to check the phase
rotation at the source terminals. Rewire the
transfer switch source terminals to obtain the
correct phase sequence if necessary.
Note: The default setting for the phase rotation on
the controller is ABC. If the application uses
a phase rotation of BAC, use the Source
Setup screen to change the phase rotation
setting on the controller.
5. If the source is a generator set, stop the generator
set by moving the master switch to the
OFF/RESET position.
6. Repeat steps 2 through 5 for Source E.
7. Close and lock the transfer switch enclosure door.
8. Move the generator set master switch to the AUTO
position.
Note: If the engine cooldown time delay setting is
not set to zero (default setting), the
generator set may start and run until the
Engine Cooldown Time Delay ends.
9. Perform the lamp test and then proceed to the
automatic operation test.
5.6 Lamp Test
Refer to the controller operation manual for instructions
to perform a lamp test. Ve rify that all controller LEDs or
lamps are operational.
5.7 Automatic Operation Test
Check the transfer switch’s automatic control system
immediately after the voltage check. Refer to the
controller Operation Manual for instructions to run the
automatic operation test.
Note: Close and lock the enclosure door before starting
the test procedure.
5.8 System Setup
Set the controller’s current time and date. See the
controller Operation Manual for instructions.
The transfer switch is factory-set with default settings for
time delays and other parameters. See the controller
Operation Manual for instructions to view and change
settings, if necessary.
Note: Use caution when changing transfer switch
settings. The source voltage and frequency
settings must match the values shown on the
transfer switch nameplate.
5.9 Exerciser Setup
Set the exerciser to start and run the generator set at
least once a week. See the controller Operation Manual
for instructions.
5.10 User Interface Cover
The gasket-sealed, hinged user interface cover
prevents unauthorized access to the transfer switch
controls and protects the user interface from harsh
environmental conditions. The cover is available as an
optional accessory for NEMA 1 enclosures. NEMA 3R
enclosures include the cover as standard equipment.
Use a customer-supplied padlock to lock the cover.
5.11 Startup Notification
Perform the system startup procedure explained on the
Startup Notification Form. The Startup Notification
Form covers all equipment in the power system.
Complete the Startup Notification Form and register the
