The optional external switch must be connected between Terminals H and L. A pressure switch may also be used as a method of en
-
abling. When enabled, IDLE has an independent Gain adjustment.

The Auxiliary (Aux) input, Terminal M, accepts signals from
auto synchronizers, load sharing units, and other GAC acces-
sories. Auxiliary Input Polarity (AUXP) set for InC: Increases
Speed w/ Increased Voltage or dEC: Decreases Speed w/ In-
creased Voltage. Aux input is nominally 5.0 V +/-

Turning the Light Force Governor, (LFG) feature ON (default is OFF) scales the governor’s proportional response (GAIN) for the best
resolution when controlling small actuators, like the T1 ATB, ALR/ALN, 100/103/104 series and normally closed Cummins EFC actua-
tors. Turn the LFG feature ON for use with these low current actuators.
The letters LFG display in place of the Primary Parameter Units when adjusting GAIN and STABILITY to indicate the feature is ON.
The LFG Feature can only be turned ON or OFF when the engine is not running.
Turning the Lead Circuit (LEAD) ON (default is ON) enables the governor to be more responsive and typically increases the range of
GAIN adjustment. Turn Lead Circuit ON when there is slow or moderate hunting at higher GAIN settings.
Turning the Speed Anticipation feature (
SanT)
ON (default is OFF) reduces RPM recovery time during high load transients, it requires
both no load (NLCU) and full load current (FLCU) values to be entered correctly.

SSWS is the SPEED SWITCH setting, RPM range is 250 to 4000 RPM. Default setting is 2000 RPM.
SSWP sets the output polarity at either nO (normally open) or nC (normally closed). Default is set at nO.
SSWL sets the speed switch LATCH. With the Latch ON and the speed switch setting exceeded (based on SSWP) the output state is
latched until power is cycled. With the Latch setting OFF, the output state of the terminal automatically resets at 0 RPM. Default is ON.
