COUPLER GP-QUICK 2063820 - Caterpillar

Requirements for the Control System
The engine control system requires a clean 24 VDC power supply that is capable of supplying 30 amperes of continuous power.The maximum allowable AC ripple voltage is 150 millivolts AC peak to peak. For the wiring, the maximum allowable voltage drop is 1 VDC from the power supply to the Electronic Control Module (ECM) in the engine mounted terminal box.Actuators on the engine draw current in all modes for the engine control. A auxiliary charging system is recommended in order to maintain battery power while the engine is not running. If an auxiliary charging system is not at the engine's site the battery power should be disconnected through the 35 Amp breaker in the junction box when the engine is not running. Separate the power supply for the engine control from the power supply for the starting motor. From the factory, the engine's power supply for the engine control is also the power supply for the starter.
