Fault Status:
When the elevator is stopped, all the signals can not be registered, were unable to run the express slow, the first suspect is a safety circuit failure. Should go to the room to observe the state of the control panel of the safety relay. If the safety relay is released state, should determine the safety circuit fault.
Malfunction Possible causes:
1. The input power supply phase sequence or phase error caused by the phase sequence relay.
2. Lift the load in the super long run or stall, causing thermal relay.
3. may cause the governor overspeed governor for switching.
4. The elevator hoisting or sink to the bottom causing limit switch.
5. Pit broken rope switch. Might be the governor rope or long jump.
6. safety gear. Should investigate the cause. The governor may be speeding action, the governor oil loss malfunction pit sheave oil loss, pit sheave foreign objects (such as a mouse, etc.) involved, and other security deed block gap is too small...
