Intelligent valve electric device static loss and motion loss stage causes and processes

The loss phase is divided into static and motion. In the "local control" mode, the intelligent valve electric device can be operated; if the "loss phase" appears immediately, it is a static loss phase or the "loss phase" appears after 1 to 2 seconds, which is a motion loss phase.

Causes and processes of static loss phase

Cause 1: One phase of the three-phase power supply of the actuator is lost; Step 1: Check the voltage of the actuator terminal box and eliminate the loss phase. Cause 2: Volatility of the connecting rod in the actuator; Step 2: Reconnect the link in the actuator. Cause 3: The components on the power board of the actuator are damaged; Step 3: Replace the power board in the actuator.

Causes and processes of motion loss phase

Cause 1: Volatility of the connecting rod in the actuator; Step 1: Reconnect the connecting rod in the actuator. Cause 2: The AC contactor in the actuator is damaged; Step 2: Replace the AC contactor in the actuator. Cause 3: The motor in the actuator is damaged; Step 3: Replace the motor in the actuator. Cause 4: The components on the power board of the actuator are damaged; Step 4: Replace the power board in the actuator.
