Fault check and maintenance

●Mechanical fault check

1. After pulling the switch handle, drive the valve with the handwheel to check whether the hand-electric switch is sensitive and reliable.

2. Check the action and indication of the mechanical opening indicator.

3. If the handwheel does not move and the valve is blocked, the repair valve should be removed. If the valve can be driven by the handwheel, check the electrical part.

4. If the manual operation is normal, there is no interference, and the valve stem does not work, it is necessary to check whether the connection of the valve stem joint is reliable.

●Electrical fault check (check the external controller first, then check the electric device)

1. Check the main power supply and control power supply, relay, fuse and all indicators and switches are normal.

2. Check the motor and replace it if there is a problem.

3. If the micro switch fails, it can be solved by replacing the relevant original.

●Maintenance

It is recommended to perform two routine maintenance or regular maintenance every year.
