When the underground mining locomotive start indicator is on, but the locomotive cannot work, we need to stop the electric locomotive immediately and carry out the next inspection work
Check whether there is voltage output at pin 1 of controller a socket. If yes, check the power contactor DC and related circuits.
If there is no voltage output at pin 1 of controller a socket, check whether pin 1 and 4 are connected and whether the control board is normal.
Check whether the reversing contactor is connected, whether the motor and corresponding lines are disconnected, and whether the carbon brush is excessively worn, and repair or replace it.
Check the voltage of 4 and 5 pins of B socket. If 5 pins have 15V, and 4 pins have no voltage (given output), the photoelectric setter is broken, repair or replace it; if 5 pins have no 12V output, the control board is broken and needs to be replaced.
The battery locomotive current sensor has no negative voltage, the ground wire is disconnected or the current sensor is damaged. Check whether the current sensor socket is in good contact, connect its circuit or replace the current sensor.
