Controls and Indicators, Starting Generator Set

2.3.1Controls and Indicators

Figure 2-2 describes the controls and indicators located on the ADC 2100. The LED display indicates generator set status as shown in Figure 2-2.

With the factory-installed continuous power mode jumper in place, the LED display is activated when the generator set master switch is moved to the RUN or AUTO position and remains active until the master switch is moved to the OFF/RESET position or power to the controller is removed. If the continuous power mode jumper has been disconnected, the LED display is activated by a start or RUN command and turns off 48 hours after generator set shutdown. See Section 2.5.

The buttons on the controller keypad are used only for system configuration and adjustment. The system configuration is factory-set and should not require changes under normal operating conditions. Contact an authorized distributor/dealer or service technician if adjustments are required.

2.3.2Starting Generator Set

The following procedures describe the actions required to start the generator set.

The controller attempts to start the generator set three times (three crank cycles, 15 seconds crank and 15 seconds off). If the generator set does not start in three attempts, the system shuts down on an overcrank fault.

Local Starting

Move the generator set master switch to the RUN position to immediately start the generator set.

Auto (Automatic) Starting

Move the generator set master switch to the AUTO position to allow startup by an automatic transfer switch (ATS) or remote start/stop switch, if equipped.

2.3.3Stopping Generator Set

The following procedures describe the actions required to stop the generator set.

Local Stopping

1.Run the generator set at no load for at least 2 minutes to ensure adequate engine cooldown.

2.Move the generator set master switch to the OFF/RESET position. The engine stops.

Automatic Stopping

With the generator set master switch in the AUTO position and an (ATS) or other automatic device connected to controller leads 3 and 4:

1.The ATS or other device disconnects the load from the generator set.

2.If the ATS is equipped with an engine cooldown time delay, the generator set continues to run for a preset engine cooldown time.

Note: There is no engine cooldown time delay on the ADC controller.

3.The ATS or other device opens the connection between controller leads 3 and 4. The generator set shuts down.
