Check the emergency stop switch and fault code
The reset method of the emergency stop of the food delivery elevator needs to be handled in steps according to the fault type and the cause of the emergency stop. The core is to perform targeted operations by checking the status of the emergency stop switch and the fault code. The specific process is as follows:
Check the status of the emergency stop switch
If the elevator displays an emergency stop fault, it is necessary to check whether the emergency stop switch of each floor is in the same direction (the correct state is "0" on the top and "1" on the bottom).
If it is found that the direction of the emergency stop switch on a certain floor is inconsistent, it needs to be adjusted to be consistent with other floors to ensure that all emergency stop switches are closed normally.
Handle according to the fault code
Display EY: Check whether the key of the elevator call panel on the first floor is in the open state. Turning on the key can restore to normal.
Display E1: Check whether the signal line connected to the elevator call panel is in poor contact or detached, and reconnect the signal line.
Display E2/E3: The upper and lower limit switch positions need to be adjusted. For example, if E2 prompts the upper limit switch protection, the upper limit switch should be recalibrated after the elevator moves downward manually; E3 needs to adjust the lower limit switch after moving upward.
Safety measures and professional support
Before resetting, it is necessary to confirm that the cause of the fault has been eliminated, such as checking for hidden dangers such as short circuits and safety clamps.
If you cannot solve it yourself, you need to contact professional maintenance personnel to avoid secondary faults or safety hazards caused by misoperation.
Summary: The core of emergency stop reset of food delivery elevators is to check the status of the emergency stop switch and the fault code indication, and solve the problem through targeted adjustment or calibration. If the electrical system or mechanical components are damaged (such as motor burnout, safety clamp action, etc.), it needs to be repaired by professionals.
