Kohler Comprehensive Guide to the ADC 2100 Controller Manual

6.4ADC 2100 Continuous Power Mode Jumper

A jumper on connector P7 on the back of the controller causes the controller to remain powered at all times. Controllers are shipped from the factory with the jumper connected. Disconnecting the jumper causes the controller to automatically power down 48 hours after the generator set shuts down. See the wiring diagram and schematic drawing in the operation manual.

Note: Be advised that the ADC consumes 250 mA when the master switch is in the AUTO position with the jumper connected. If you do not plan to use your generator set for a long period of time, Kohler recommends moving the master switch to the OFF/RESET position (0 mA draw). Remote communications require an active (powered-up) controller.

Note: For most applications, it is not necessary to disconnect the continuous power mode jumper.

Procedure to disconnect the continuous power mode jumper (optional).

1.Prevent the generator set from starting.

a.Move the generator set master switch to the OFF/RESET position.

b.Disconnect power to the battery charger, if equipped.

c.Disconnect the generator set engine starting battery, negative (--) lead first.

2.Remove the controller from the generator set.

a.Disconnect the engine wiring harness connector P1 plug (35-pin) from the controller. Disconnect the J15 and J16 connectors. See Figure 6-3.

b.Remove the controller from the generator set housing in order to access the back of the controller.

3.Remove the controller’s back cover to access the jumper.

a.Note the labels on the three leads connected to the generator set master switch for reconnection later. Disconnect the leads at the pink connectors. See Figure 6-3.

b.Remove the cover screws and remove the controller’s back cover. See Figure 6-3.

4.Locate the P7 connector near the top of the controller. See Figure 6-3. Remove the jumper from pins 1 and 2 of the P7 connector. If the P7 connector has three pins, connect the jumper across pins 2 and 3 for storage.

5.Replace the controller’s back cover and secure the cover screws.

6.Reconnect the three pink connectors to the generator set master switch.

7.Reconnect the J15 and J16 connectors.

8.Reconnect the engine wiring harness connector P1 plug (35-pin) to the controller.

9.Reinstall the controller in the generator set.

10.Reconnect the generator set engine starting battery, negative (--) lead last.

11.Reconnect power to the battery charger, if equipped.

12.Place the generator set master switch in the AUTO position.
