Product Overview: 

Keystart 9620 and 9621 control modules provide manual start/stop and automatic fault protection for generators, pumps and other engine-driven applica-tions. Outputs allow control of engine fuel (energized to run),  starter motor and preheat. The Keystart also has an alarm output for remote or audible warning of faults.

Six LEDs and icons indicate engine status and faults. Four switch inputs (closing to negative on fault) enable automatic shutdown on engine low oil pressure, high coolant temperature and auxiliary faults. Model 9621 has a fully adjustable engine overspeed shut-down feature, configurable for either generator AC or magnetic pickup speed signals. Charge alternator excitation and a charge fail warning LED are standard. 

Electrical connection is by quick-connect, spring-clamp terminal blocks. A universal 7 to 30 VDC power supply permits operation with 12 or 24 VDC engine batteries, with standard engine crank-dip voltage protection.

Keystarts are mounted in the front through a standard cutout and secured at the rear with quick-fit clips. Epoxy resin case encapsulation gives superior vibration/shock resistance and environmental protection.
