Actuator Duty Cycle

100%= 11 Bars

90-99% = 10 bars

...

10-19% = 2 bars

1-95% = 1 bar

0% = 0 bars

Engine Speed

Middle bar = set point

Top bar = Set point + 10 RPM

Bottom bar = set point - 10 RPM

FEATURES

TRIM or VARIABLE SPEED OPERATION

Trim Function - Performs finer adjustments (e.g. generator frequency) The

resistive input speed function is active when the VSPD (Variable Speed)

parameter is "OFF" (default value is OFF). 5K Ohm potentiometer typical.

Variable Speed Function - Operates over a larger RPM range. Variable

speed 0 - 2.5 volt input to terminal 'J' is active when VSPD (Variable Speed)

parameter is "ON".

4-20mA input requires an external 200 Ohm resistor across H & J

The optional external switch must be connected between

IMPORTANT

terminals "H" and "L". A pressure switch may also be used

as a method of enabling. When enabled, IDLE has an independent Gain

adjustment.

ACCESSORY INPUT

The Auxilary (Aux) input, terminal 'M', accepts signals from auto synchroniz-

ers, load sharing units, and other GAC accessories.
