Tensioner manufacturer safety write light: software safety light is on, it means that the software circuit is not faulty, look at the brake handle and the main handle are located in zero position, or, touch the winding switch, make the reverse switch reset, switch to 1 or 2 position respectively, press the fault release button. When the tensioner die safety circuit is reset, it can indicate the case that the winding switch is mistakenly operated or inhibited. After processing, the unwind can be returned to the 0th position and the chain tensioner operates normally. Also, when the driver stops the lubrication pump of the oil pressure type, there are cases when the operator touches the console and presses the stop button and the frequency converter is turned off. At this time, the frequency converter is in the discharge stage, and the software detects that there is no power drop at the point, only that the street light is safely turned off, so the fault release cannot restore the safety circuit. Even if the software waits until the street light, the frequency converter starts the inverter and restores the safety circuit after the electricity is turned off. Also, pressing the fault release button immediately after just starting the inverter will not restore the circuit. You can restore the safety circuit after the inverter is fully operational.
