If a machine's engine is cranked (turned or wound over) and fails to start, the continued cranking of the engine results in excessive heat and load on the starting circuit. This results in damage or premature failure of batteries, starter motors and cabling. This decreases the life of the machine's starting circuits which in turn reduces machine availability and productivity.
The Muirhead® Overcrank Protection kit preserves the starting system by preventing crank when the engine is turned on and limiting the amount of times the engine may be cranked; then locking out the start circuit to allow for system components to cool down. This reduces the flattening of batteries and abuse of an engine's starting components – helping to extend the life of the system as a whole.
The Overcrank Protection system will provide a visual indication to the operator – alerting them when a starting circuit is isolated. An override switch may be incorporated to allow maintenance staff to carry out servicing tasks without the start circuit being inhibited.
Basic on-machine configuration of both the crank time and start interlock periods, or advanced programming are available through a PC using the Muirhead® Programmable Controller Utility (PCU) software package.
