Abstract:

Abstract: MT5500 truck uses dynamic braking mode to realize deceleration. A programmable controller PLC system is installed on the MT5500 truck, when the PLC system monitors the abnormal closure of contactor, the system forces other contact closure to play shunt protection role, which can make the brake contactor operation of MT5500 trucks more perfect and reasonable.
