If the IDLE speed setting was not adjusted as detailed in Section 9 Starting

(140)

Fuel Adjustment, then place the optional external selector switch in the IDLE

position.

The idle speed set point is increased by the clockwise rotation of the IDLE

adjustment control. When the engine is at idle speed, the speed control unit

applies droop to the governor system to ensure stable operation.

If not using the idle method, you can lower idle to the bare minimum (even if it's

not being used) for smoke reduction.

Switch 1(C1) controls the Lead Circuit. The normal position is ON.

Move the switch to the OFF position if there is fast instability in the

system.

fast erratic engine behavior between the engine and generator due to

a soft coupling.

acceSSorY InPut

The Auxiliary Terminal N accepts input signals from load sharing units,

auto synchronizers, and other governor system accessories, GAC ac-

cessories are directly connected to this terminal.

note

Terminal N is sensitive (145 Hz/V). Accessory connections

must be shielded.

When an accessory is connected to Terminal N, the speed will de-

crease and the speed adjustment must be reset.

If the auto synchronizer is used alone, not in conjunction with a load shar-

ing module, a 3 Ω resistor should be connected between Terminals N and

P. This is required to match the voltage levels between the speed control

unit and the synchronizer.

acceSSorY SuPPLY

The +10 volt regulated supply, Terminal P, can be utilized to provide power to GAC governor system accessories. Up to 20 mA of current can

be drawn from this supply. Ground reference is Terminal G.

A short circuit on this terminal can damage the speed control unit.

Do not connect Terminals N and P directly to each other.
