Questions answered in SEMEM manuals
What is the working voltage of the DFK controller?
The controller operates at 220 V, 50 Hz.
How can the valve opening display be set to 100%?
When the valve is fully open, adjust the potentiometer so the opening‑degree indicator shows 100%.
How do I switch between local and remote control modes?
Use the 现场/远控旋钮 to select the working mode; the local light turns on for local control and the remote light turns on for remote control.
From: SEMEM DFK-1G/-2G Electric Valve Controller User Manual
What do the indicator lights on the front panel mean?
The green valve‑open light flashes while opening and stays solid when fully open; the yellow valve‑close light behaves similarly for closing; the red accident light indicates overload or torque fault.
