Winch Relay Pack - Description

DESCRIPTION




Figure 1 - RELAY PACK





Electrical operation of the control assembly consists of four heavy duty relays, a thermal-switch located on the motor armature brush holder and a Low Voltage Interrupt (LVI) located in the control assembly. The thermal-switch interrupts the power-in function and the LVI affects both the power-in and power-out functions and must be reset by allowing the charging circuit voltage to rise above 10 volts for more than 30 seconds. The thermal switch is reset only by allowing the winch motor to cool adequately (about 30 minutes). Relay number 1 and 3 control current flow through the field windings and relay number 2 and 4 supply current to the motor armature.
