Details
The ProAct control system is designed to control the speed of engines in mechanical drive or generator set service. The electric powered ProAct actuator has 75° of rotation and is designed for direct drive of the butterfly valve on gas engines, and through linkage the racks on diesel engines.
Actuators are available in different sizes to fit specific control demands. In most cases, the ProAct II actuator will be used. The ProAct II provides 6.8 J (5.0 ft-lb) of work (transient) and 2.7 N·m (2.0 lb-ft) of torque. The ProAct I is extremely fast and provides 3.4 J (2.5 ft-lb) of work (transient) and 1.4 N·m (1.0 lb-ft) of torque at steady state. ProAct I controls may be operated on nominal 12 Vdc systems. ProAct II controls require nominal 24 Vdc supply.
Larger output ProAct III and ProAct IV controls are available. Information on these actuators is in manual 04127. The ProAct Digital Speed Control includes an input for a 4 to 20 mA remote speed reference setting, an internal speed reference for local control of speed, and an auxiliary voltage input for load-sensor connection in load-sharing applications.
A fuel limiting version is also available. The ProAct control system includes:
a ProAct Digital Speed Control
an external 18–32 Vdc (24 Vdc nominal) power source for Model II or a 10– 32 Vdc power source for Model I
a speed-sensing device (MPU)
a ProAct I or ProAct II actuator to position the fuel rack
a hand held terminal for adjusting control parameters
an optional load sensing device
The ProAct Digital Speed Control (Figure 1-2) consists of a single printed circuit board in a sheet metal chassis. Connections are via two terminal strips and a 9- pin J1 connector.
The control chassis has an aluminum shield to protect the circuits from electromagnetic interference (EMI) and electrostatic discharge (ESD).
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.
