Rolling shutter door repair manufacturer Shijingshan District, Shijingshan District, Beijing, electric rolling shutter door repair price. Due to the frequent entry and exit of vehicles at some gates and the frequent opening and closing of the gates, some problems have occurred recently. Here is a summary of some common faults we encountered during maintenance. The motor does not move or rotates slowly. The cause of this fault is usually the wiring. It is caused by the circuit breaker, the motor being burned out, the stop button not being reset, the limit switch acting under a large load, etc. Solution: Check the circuit and connect the replaced burned motor. Replace the button or press the limit switch slider several times to separate it from the micro switch contact, and adjust the micro switch position to check whether the mechanical part is jammed. If If there are any, remove the jam and clear the obstacles. The location and cause of the control failure failure. The electrical appliance (contactor) contacts are stuck.

The cause of the problem is that the ring chain blocks the cross groove pawl and does not break away. The ratchet chain press frame is stuck. Treatment method: Straighten out the ring chain, adjust the relative position of the pawl and the chain pressure frame, replace or lubricate the pin. The motor vibrates or makes a lot of noise.
