8. Auxiliary input
Auxiliary terminal "N" receives signals from the load divider, automatic parallel feeder or other auxiliary
devices in the governor system. Connect auxiliary devices for the speed controller directly to this "N" ter-
minal. Use shielded wires when connecting wiring. When the automatic parallel feeder is used inde-
pendently from the load divider, a 3 m resistor must be used between terminals "N" and "P" in order to
adjust the voltage of the engine speed controller and parallel feeder.
The engine rpm drops when an auxiliary device is connected to terminal "N," so be sure to reset the con-
troller.
A jumper must be used between terminals "G" and "J" or the frequency must be adjusted when the engine
speed controller is operating at the maximum acceptable frequency.
When using this device, the acceptable frequency range of speed control is increased to over 7,000 Hz.
9. Auxiliary supply
Power can be supplied to auxiliary devices in the governor system at terminal "P" at an even voltage of
+10 V, with a maximum current of 20 mA.
Terminal "G" is the reference potential terminal for terminal "P." If terminal "G" is short-circuited, the
engine speed controller may be damaged.
10. Remote speed adjustment
A speed adjustment potentiometer is required in order to continuously adjust the engine speed remotely
over a certain speed range.
Refer to the following chart in order to select a potentiometer to suit the uses based on the required speed
range. If the required speed range is not in this chart, select a potentiometer for a range which is one level
higher.
In order to obtain the correct speed range, additional fixed resistors can be attached to both ends of the
potentiometer. Connect the potentiometer for setting the speed range according to the following wiring
connection diagram.
CAUTION
The generator set supplied by Doosan does not include a speed potentiometer for remote
control. The consumer must install one themselves if they desire remote control. In order to
obtain engine stability at a very low speed setting, a droop potentiometer can be used to
obtain a small amount of droop.
On the other hand, when the speed setting is at its highest, the actuator runs almost stably
regardless of the set droop value.
