Breaker “ON”/”OFF” in radio remote

The control system allows the main circuit breaker on the miner to be turned on and off using the radio remote control console. This normally requires that a battery backup version of the power supply be installed on the machine.

To turn the breaker off:

 Press and hold the “SHIFT” and “C.B. OFF” keys together for two (2) seconds. After two (2) seconds, the breaker off solenoid will energize, turning off the machine circuit breaker.

To turn the breaker on:

It is essential that a battery backup version of the control system power supply be installed for this function to be available. Typically, a hydraulic valve provides the mechanical force for the breaker mechanism. To allow this valve to be operated after loss of power, a hydraulic accumulator is charged by the pump motor during normal “powered” operation of the machine. If the hydraulic accumulator is discharged, then it will not be possible for the breaker to be turned on from the remote.

 Press and hold the “SHIFT” and “C.B. ON” keys together for two (2) seconds. After two (2) seconds, the breaker on solenoid will energize, turning on the machine circuit breaker.

IMPORTANT! The backup accumulator must maintain a minimum pressure of 500 psi for 12 minutes after the pump has been de-energized.
