Description
Keystart 9620 series control modules provide manual start/stop and automatic fault protection for generators, pumps and other engine-driven applications.
Operator control is by a 3 position keyswitch, with the key removable only in the Stop/Reset (O) position. Outputs are provided for the control of engine fuel (energised to run), starter motor and preheat. The Keystart also has an alarm output for remote/audible warning of faults.
Indication of engine status and faults is by six LEDs and pictograms. Four switch inputs (closing to negative on fault) provide for automatic shutdown on engine low oil pressure, high coolant temperature and auxiliary faults. Model 9621 has a fully adjustable engine overspeed shutdown feature, configurable for either generator AC or magnetic pickup speed signals. Charge alternator excitation and a charge fail warning LED are fitted as standard.
Electrical connection is by quick-connect, spring-clamp terminal blocks. A universal 7 to 30VDC power supply allows operation with 12 or 24VDC engine batteries, with engine crank-dip voltage protection fitted as standard.
Keystarts are 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.
