PowerGuard Automatic Controller

PowerGuard Automatic Control monitors engine speed through a gear tooth sensor mounted to the 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 switch.
