3.4.2 TRANSFER BACK TO UTILITY POWER SOURCE
When utility power has been restored, transfer back to that source
and shut down the generator. This can be accomplished as fol-
lows:
1. Set the generator’s main circuit breaker to its OFF (or OPEN)
position.
2. Let the engine run for a minute or two at no-load to stabilize
the internal temperatures.
3. Set the generator’s AUTO/OFF/MANUAL switch to its OFF (or
OPEN) position. The engine should shut down.
4. Check that utility power supply to the transfer switch is turned
OFF.
 Do not attempt to activate the transfer switch
manually until all power voltage supplies to
the switch have been positively turned off.
Failure to turn off all power voltage supplies
may result in extremely hazardous and pos-
sibly fatal electrical shock.
5. Use the manual transfer handle inside the transfer switch to
move the main contacts back to their UTILITY position, i.e.,
loads connected to the utility power source (Figure 3.2).
6. Turn ON the utility power supply to the transfer switch using
the means provided.
7. Set the system to automatic operation as outlined in Automatic
Transfer Operation section.
3.5 SIDE COMPARTMENT
(FIGURES 3.3 & 3.4)
Local codes may require this compartment to be locked. A hasp is
provided so the owner can secure the compartment with their own
padlock. Check local codes in the area.
3.5.1 MAIN CIRCUIT BREAKER
This is a 2-pole breaker rated according to the Specifications sec-
tion.

3.5.2 EXTERIOR READY LIGHTS
• Green LED ‘Ready’ light is on when utility is present and switch
is in AUTO indicating the generator is ready and when the gen-
erator is running.
• Red LED ‘Alarm’ light is on when the generator is OFF or a fault
is detected. (See the Protections Systems section.)
• Yellow LED ‘Maintenance’ light (See the Protections Systems
section.)

3.6.1 ALARMS
Highest Priority (Latching) Displayed on the control panel and the
external red LED. They must be cleared before the alarm message
goes away. The alarm log records each occurrence (see Appendix
- "Menu System").
Low Oil Pressure (Shutdown Alarm)
A five (5) second delay on start-up and seven (7) second delay
once the engine is running.
This switch (Figure 3.5) has normally closed contacts that are
held open by engine oil pressure during operation. Should the oil
pressure drop below the five (5) PSI range, switch contacts close
and the engine shuts down. The unit should not be restarted until
oil level is verified.
High Engine Temperature (Shutdown Alarm – Auto Reset)
A 10 second delay on start-up and one (1) second delay before
shutdown. Auto reset when the condition clears and restart the
engine if a valid start signal is still present.
This switch’s contacts (Figure 3.5) close if the temperature should
exceed approximately 144° C (293° F), initiating an engine shut-
down. Once the oil temperature drops to a safe level the switch’s
contacts open again.
