Installation Guide

Testing
1. Switch the generator’s main circuit breaker, located on control panel in the OFF position and also
put the ATS switch in the OFF position.
2. Make sure utility power is OFF and place all of the priority circuit breakers in the transfer switch
in the OFF position as well.
3. Locate the transfer of power switch inside the ATS; use included handle to move the main
contacts to the standby power, or generator position.
4. NEVER OPERATE THE TRANSFER SWITCH MANUALLY WHEN LOADS ARE CONNECTED!
5. Start engine by turning fuel and power switches in ON position. Allow fuel to ow for 15 to 20
seconds. Test and smell for gas leaks. Press “MAN” button rst then press start button
6. Allow the engine to warm up, and then switch the generator’s main breaker to the ON position.
The generator is now supplying electricity to the transfer switch but is not carrying any load.
7. Be sure that voltage and frequency from the generator is correct. If line-to-line voltage is not
approximately 120/240 volts, refer to the Owner’s Manual for the proper adjustments needed.
8. On all models, if line-to-neutral voltage is not 120 volts, check the neutral connection between
the generator and transfer switch.
9. When nished checking voltage, switch the generator’s main circuit breaker OFF and push the
OFF button to shut down the generator.
10. Make sure the 2-pole circuit breaker installed in the main distribution panel is in the OFF
position.
11. Use the transfer handle to move the main contacts in the transfer switch to (utility position).
Switch the 2-pole breaker ON in the distribution panel.
12. Now switch the generator’s main breaker ON, and put the mode switch on AUTO.
13. Shut OFF utility power and make sure the generator starts automatically.
14. If everything works correctly, switch the main breaker to ON position and make sure that power is
automatically transferred back to the utility and standby power shuts down automatically.
15. After engine has completed its cool down cycle and shut down, shut OFF utility power again.
16. When the generator is supplying power to the transfer switch, move the breakers in the switch to
the ON position, one at a time, until the generator has accepted the entire selected load.
IMPORTANT
17. With the generator carrying the entire priority load, recheck gas pressure to verify that it is at the
same level it was before the generator was started.
18. Even if the generator is running smoothly at this point, a drop-in gas pressure indicates that the
supply is barely adequate to supply the generator’s needs. Changes in the generator load, or
additional gas demand by other appliances may affect the generator’s overall performance. Verify
gas pressure and pipe size.
19. Switch the main breaker ON to restore utility power.
20. The generator will continue to run to allow the engine to cool down before shutting down.
21. Close the main breaker to restore utility power and allow the engine to cool its self down and shut
off automatically.
22. Operational tests are now complete. Refer to – Setting the Automatic Exercise Function to
complete the installation.
23. Testing is now complete.
24. Refer to SmartGen Controller Manual: Setting Automatic Exercise Function to complete
installation.
