TP-6196 10/09 47Section 4 ADC 2100 and DC 2200 Controllers
A jumper across controller pins P7-1 and P7-2 maintains
power to the controller at all times. Controllers are
shipped with the jumper connected for continuous
power. See Figure 4-14.
Note: The controller is powered by the generator set
engine starting battery. The 8.5 and 12 RES
generator sets are equipped with factory-
installed battery chargers to prevent battery
discharge.
The P7 connector has either 2 or 3 pins. Disconnecting
the jumper or moving the jumper to pins P7-2 and P7-3
allows the controller to power down automatically
48 hours after the generator set shuts down if the
generator set master switch is in the AUTO position. A
remote start signal (from a transfer switch or a remote
start/stop switch connected to controller leads 3 and 4)
or moving the generator set master switch to the RUN
position turns the controller back on.
Use the following procedure to disconnect the jumper, if
desired.
1. Engine wiring harness connector plug (P1)
2. Continuous power mode jumper location (P7)
3. J15 connector
4. J16 connector
5. Generator set master switch
6. AUTO
7. VBAT
8. RUN

Procedure to disconnect the continuous power
mode jumper (optional).
Note: For most applications, it is not necessary to
disconnect the continuous power mode jumper.
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.
c. Disconnect the generator set engine starting
battery, negative (--) lead first.
2. Remove the controller from the generator set
housing.
a. Disconnect the engine wiring harness
connector P1 plug (35-pin) from the controller.
Disconnect the J15 and J16 connectors. See
Figure 4-14.
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 4-14.
b. Remove the cover screws and remove the
controller’s back cover. See Figure 4-14.
4. Locate the P7 connector near the top of the
controller. See Figure 4-14. 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 as shown in
Figure 4-14.
7. Reconnect the J15 and J16 connectors.
8. Reconnect the generator set engine starting
battery, negative (--) lead last.
9. Reconnect power to the battery charger.
10. Place the generator set master switch in the AUTO
position.
