Components
The PRO-S pressure governors consists of the following components:
Control Module
Pressure Transducer
Throttle Servomotor (Non-electronic engines only.)
High Idle Kit (Optional)
Cables
Control Module
The pressure governor control module is waterproof and has dimensions of 4.25
inches high by 4.25 inches wide by 3.5 inches deep (4.5 inches deep on non-electronic
and 24 VDC units). All controls and indicators are located on the front of the control
module. (Refer to Controls and Indicators.)
Pressure Transducer
The pressure transducer is mounted on the pump discharge manifold. It provides
an input signal to the control module that is proportional to the discharge pressure.
Throttle Servomotor (Non-Electronic Engines Only)
The throttle servomotor is installed on engines that do not have electronic engine
control systems. It provides the mechanical connection between the control module
and the engine throttle. The travel of the linear actuator arm is 1.85 inches.
High Idle Kit (Optional)
The High Idle Kit provides the components to install this option including a DPDT
switch, 2500 ohm potentiometer, an indicator light, two diodes, and a cable.
