| Description Keystart 7210 and 9610 series controls provide manual start/stop and automatic fault protection for generators, pumps and other engine-driven applications. The units are available in two sizes: the 7210 series uses a DIN 72mm case (for 68 x 68mm panel cut-outs); 9610 series units have a DIN 96mm case (for 92 x 92 mm cut-outs). Operator control is by a 3 position keyswitch on the front facia - see overleaf for operation details. The key is common to all Keystarts and 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. The front facia has six LED and pictograms for indication of engine status and faults - details overleaf. Fault shutdown switch inputs (closed to negative on fault) are provided for engine low oil pressure, high engine temperature and auxiliary/plant fault. Models 7211 and 9611 have a fully adjustable engine overspeed shutdown, driven by generator AC or magnetic pickup. Charge alternator excitation and a charge fail warning LED are fitted as standard. Electrical connection is by spring-clamp terminal blocks at the rear. The Keystart has a universal 7 to 30VDC power supply, allowing operation with 12 or 24VDC engine batteries. Engine cranking brown-out protection is fitted as standard. Warranty A two year limited warranty on materials and workmanship is given with this product.
