Control Applications
The ProAct II control requires 18–32 Vdc (24 Vdc nominal) uninterrupted power
supply, with 125 watts as the maximum power consumption at rated voltage.
ProAct I requires 8–32 Vdc (12 or 24 Vdc nominal) uninterrupted power supply
with 50 W as the maximum power consumption at rated voltage.
ProAct actuators are designed to directly link to the butterfly in the gas engine
carburetor. The control can be programmed to have variable gain to compensate
for the variable gain characteristics of carbureted gas engines.
Diesel engine applications can use the control programmed to accommodate
non-linear fuel controls or non-linear linkage arrangements.
Speed Control Accessories
Hand Held Programmer (Figure 4-1, part number 9907-205) is used to adjust
the ProAct control. It plugs into the serial port (J1 connector) of the control.
Generator Load Sensor (part number 9907-026) for load sharing or droop-
parallel generator applications. This will connect to the Aux input on the control.
SPM-A Synchronizer for synchronizing the generator phase to that of the power
bus. The synchronizer generates a close-generator-breaker signal to parallel the
generator with the power bus. Connect the synchronizer to the Aux input to bias
the speed setting.
Actuator Accessories
Electrical plug to match plug on the actuator:
1631-187 straight plug
1631-633 90° plug
Actuator Lever for linkage connection:

3952-043 2-inch, 2 holes
Flexible Couplings for direct connection of the actuator output to a carburetor's
butterfly-valve shaft (dimension “X” in Figure 1-1):
