4-2. Electric Operation
Perform the electric operation with the following procedure.
① Checking power supply voltage
Check that the power source voltage conforms with the design specification of an
actuator.
② Checking wiring connection
Check that control circuits of an actuator are correctly wired, according to the wiring
diagram indicated on an actuator housing and the color codes of wires
③ Turning on the power supply
Turn on an actuator to detect if anything abnormal might happen. If anything abnormal
such as smoke emission or failure of control circuit fuse happens, immediately turn off
the actuator, detect the cause and take an appropriate corrective measure to solve
the problem.
④ Electric operation
Turn on the power supply and confirm that valve opens. Similarly, turn off the power
supply in the fully open status and confirm that the valve closes.
⑤ Others
●
In case of motor overheating, smoke emission or fuse failure, turn off an actuator,
detect the cause of failure and apply an appropriate corrective measure to solve the
problem.
●
In the electric operation, the manual lever is released free and moves in the opening
direction; this is not malfunction.
