Applications

The ProAct™ digital control system is an electric powered governor system designed to

provide precise electronic control and limiting for gas and diesel engines.

ProAct I is designed for direct coupling to the butterfly valve shaft on small gas engines or for

diesel engines which require less than 1.4 Nm (1.0 lb-ft) of torque to move the rack.

ProAct II is designed for control of most diesel engines and larger carbureted gas engines.

• 75° rotary output allows direct coupling to butterfly, eliminating linkage

• All-electric actuator requires no drive or hydraulic supply

• Programmable digital electronics permit tailoring control to various applications

• Actuators are extremely fast, electronically positioned in both directions

• Alternate dynamics for dualfuel applications or co-gen/standby

• 3 speed-activated switches

• Start fuel limit and maximum fuel limit for derating

• Manifold pressure fuel limiting

• Two-slope torque limiting
