A. C. MODULAR GENERATOR SYSTEM

Special Operating Instructions
Cold Weather Procedure:
It is strongly recommended that the generator PTO be engaged prior to leaving a heated
garage or fire station in cold weather. The system will generate enough heat to keep its
hydraulic fluid viscosity low enough for proper operation, in all but the most extremes of
low ambient air temperatures.
If the generator system is “started” when the hydraulic oil temperature is below 40
F, the
following message will be displayed on the Command & Control Center (Reference Figure
24):
Message advising the
oil is cold (less than
40
F)

Operating Modes when the system START button is activated (or when the system is in
“autostart”):
When the meter displays hydraulic oil temperatures below 20
F, the hydraulic
system will bypass the generator motor and the generator will not produce
power. This mode warms the hydraulic oil.
When the meter displays hydraulic oil temperatures between 20
and 40
F, the
generator rotor will turn at a reduced RPM and the generator will not produce
power. This warms the hydraulic oil to 40
F.
When the meter displays hydraulic oil temperatures that exceed 40
F, the
system will then commence full power generating operations.
