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.)
3.5.3 120 VAC GFCI OUTLET & 15 AMP BREAKER
(17 & 20 KW ONLY)
These models are equipped with an external, 15 amp, 120 volt,
GFCI convenience outlet that is located in a compartment on the
right side of generator (Figure 1.3).
When the generator is running, in the absence of utility power, this
outlet may also be used to power items outside your home such
as lights or power tools. This outlet may also be used when utility
power is present by running the generator in manual mode. This
outlet does not provide power if the generator is not running. This
outlet is protected by a 15 amp circuit breaker in the same com-
partment as the outlet. (Do not use when the generator is running
in exercise mode.)

PROTECTION SYSTEMS

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.
Over Crank (Shutdown Alarm)
This occurs if the engine has not started within the specified crank
cycle. (See "Cranking" section.)
The oil drain hose may be routed in the opposite direction as
shown in figure.
