Control Function Reversing Starter (REV)

Use this function in a feeder that requires a motor to start/stop in two direction of rotation (forwards/backwards).
• Relay output DO0 is used by the control function to start the motor in a forward direction.
• Relay output DO1 is used from the control function to start the motor in a reverse direction.
• Optionally DI0 can be used for contactor checkback supervision
• Optionally DI3 / DI4 can be used to start the motor and DI5 to stop the motor
• Optionally DO2 or DO3 can be used as fault output
The following diagram shows the UMC wired for REV operation. A signal lamp is connected to DO3 which serves as a fault output.
The main contactor is connected to DO0 and DO1. Two auxiliary contacts k1 and k2 are used for contactor checkback monitoring.
The motor can be started locally via DI3/DI4 and stopped via DI5. The remaining digital inputs can be freely used.
