The Murphy 12v Rack Puller RP75 connects to the injection pump or air intake shut-off lever via a cable (chain optional). A coil spring, within the RP75, is reset manually and is held in place by an electromagnet. When the Swichgauge detects a malfunction, the electromagnetic circuit is interrupted through a magnetic switch releasing the coil spring thus pulling the cable/chain to actuate shutdown.
