enclosed generator, and the number displayed corresponds to the maximum
power output of the generator in kilowatts (reference Figure 21).
The system controller is
configured to operate a generator
whose maximum output is this
number (in kW). The Er indicates the system
controller is configured to
operate an ER-series

d. If there are no active faults, pressing the Mode switch once more will return the
Command & Control Center to its normal mode. If there are active faults, they
will be displayed in succession, one each time you press the Mode switch.
See Diagnostics in the trouble shooting section for more information on faults.

Alarms, Shutdowns and Overrides provided by the Command and Control Center
The following is a list of diagnostic faults displayed by the Command and Control
Center that will cause an automatic shutdown of the system (see the Diagnostic
Faults section of this manual for a complete list of diagnostic faults.):
a. OIL HOT. If the system measures a hydraulic oil temperature that exceeds
175°F (79°C), the system will begin displaying an alarm. If the system
measures a hydraulic oil temperature that exceeds 180°F (82°C), the generator
will automatically shut down in 30 minutes unless the shutdown is overridden. If
the temperature of the hydraulic oil reaches 220°F (104°C), the system will
immediately shut down (above 220°F (104°C) the shutdown cannot be
overridden).
b.
OIL LO. If the system detects an insufficient level of hydraulic fluid in the
reservoir, it will begin displaying an alarm. The generator will automatically be
shut down in 30 minutes unless the shutdown is overridden, or the fault is
cleared by adding sufficient fluid.
c. Unb LOAD. If the system measures an electrical load imbalance between Line1
and Line 2 of more than 20% of the system’s total wattage rating, the generator
will automatically shut down in 30 minutes unless the shutdown is overridden.
See Step 7, of the “Installation Guide” for more information on balancing loads
applied to the generator.
