200- -240-Volt Configurations
The 200--240-volt configuration does not use a jumper
lead. If the unit was originally wired for straight 100--120
volt, 3-wire, remove the jumper lead (see Figure 8-16 for
location). See Figure 8-19.

8.10 Fault Shutdown Tests
Verify the operation of the generator set overspeed,
overcrank, and low oil pressure shutdowns by
performing the following tests.

Operate the generator set only when
all guards and electrical enclosures
are in place.

Servicing the generator set when it is operating. Exposed
moving parts can cause severe injury or death. Keep
hands, feet, hair, clothing, and test leads away from the belts
and pulleys when the generator set is running. Replace
guards, screens, and covers before operating the generator
set.
Short circuits.
Hazardous voltage/current can cause
severe injury or death. Short circuits can cause bodily injury
and/or equipment damage.

repairs. Remove all jewelry before servicing the equipment.
8.10.1 Controller Fault Shutdown
Functions
Check the operation of the fault functions programmed in
the ADC 2100 by performing the following tests. If the
ADC 2100 does not operate as described, check the ADC
configuration settings; see Section 7.5.2. Also check the
ADC 2100 wiring and connections; see Section 10.
Overspeed Shutdown
The overspeed setting is programmed into the ADC
controller and is not adjustable. Verify that the following
controller configuration parameters are set correctly for
your unit. See Section 7.5.2 for the settings.
D
System voltage/frequency parameter (UU)
D
Unit configuration parameter (UC)
D
Engine type parameter (EC)
D
Engine data input type parameter (ED)
Open the generator set output circuit breaker before
beginning the test. (See Figure 8-14 for the circuit
breaker location.)
Connect a DVM to measure the output frequency. Start
the generator set and manually adjust the engine speed.
See Section 4.5.
Increase the engine speed to at least 115% of the rated
engine speed, 69 Hz on 60 Hz models or 58 Hz on 50 Hz
models. Verify that the generator set shuts down on an
overspeed fault (OS). If the overspeed shutdown does
not operate, the generator set should shut down on an
overfrequency fault (OF) after approximately 5 seconds.
