PH3 POWERGUARD AUTOMATIC CONTROLLER FEATURES

PowerGuard Automatic Control monitors engine speed through a gear tooth sensor mounted to the transmission bell housing using an existing auxiliary port or by the drilling and tapping of a new port. The controller has a programmable trip point - when the programmed pre-set speed is exceeded, emergency engine shutdown will occur automatically.

Emergency shutdown can be activated at any time through a manual override button. All control and programming is completed using a membrane switch mounted in a vehicle's cab or on a control panel. An auxiliary input harness is available to expand systems to utilize external trip input signals or switches.

• Automatically activates and resets after programmable engine speed trip point is exceeded
• Manual override, programming and valve position feedback from cab / panel mounted membrane switch

By default, the time that system will remain activated after the trip is 30 seconds. A supplied light will illuminate when the valve is held closed to provide feedback to an operator that an engine may not yet be started.
