Section 2 Operation

Description

Input from a customer-supplied switch that

closes when the fault is active. The generator

set shuts down 0.3 seconds after the fault is

detected and will not start when the fault is

active (input is grounded). This protection

becomes active 3 seconds after crank

disconnect.

Shutdown occurs if the engine coolant

temperature exceeds the maximum temperature

for more than 5 seconds. This protective

becomes active after the engine reaches the

crank disconnect speed.

Not used.

Shutdown occurs if a low oil pressure condition

exists for more than 5 seconds. This protective

becomes active 30 seconds after the engine

has reached crank disconnect speed

(30 second inhibit).

Shutdown occurs after 3 unsuccessful starting

attempts. The crank cycle is set for three

starting attempts of 15 seconds cranking and 15

seconds rest.

The generator set also shuts down if no engine

rotation is sensed during cranking. Shuts down

1 second after the fault is detected.

Shutdown occurs when the governed frequency

exceeds 110% of the system's frequency

setpoint for more than 5 seconds. This

protective becomes active 10 seconds after

engine start (10 second inhibit).

Shutdown occurs if the engine speed exceeds

115% of the normal running speed for more than

0.3 seconds.

Shutdown occurs if the voltage exceeds 120%

of the system nominal voltage for more than 2

seconds.

Shutdown occurs when the governed frequency

falls below 90% of the nominal system

frequency for more than 5 seconds or below 59

Hz for more than 60 seconds. This protective

becomes active 10 seconds after engine start.

(10 second inhibit).

Shutdown occurs if the voltage falls below 80%

of the nominal system voltage for more than 10

seconds.

Indicates a software or communication problem

within the ADC 2100

Check

Check the cause of the auxiliary fault.

Check for blocked air inlets and exhaust outlets.

—

Check for leaks in the lubrication system.

Check the oil level and add oil if the level is low.

Check the fuel supply, spark plug, and battery.

Check for loose connections.
