CANstart™

CANstart™ modules provide automatic or manual start/stop control, panel gauge driving, fault indication and auxiliary shutdown protection for ECU-controlled, CANbus SAE J1939 compatible engines.

These compact controllers can be used with pumps, generators and other engine-driven applications. Operator control is through a 4 position keyswitch, and the key is removable only in the Stop/Reset (O) position. Six LEDs and icons indicate engine/ECU status and faults. Two of these LEDs, with associated inputs, indicate auxiliary fault shutdown and charge alternator fail/excitation.

CANstart™ is front-of-panel mounted through a standard square cut-out, and secured at the rear with quick-fit clips. Epoxy-resin case encapsulation gives superior vibration/shock resistance and environmental protection
