It supports 170–510 VAC for sensing input, selectable via DIP switch for 220V or 440V systems.
Use the DIP switch to select voltage range, then adjust the external voltage trim potentiometer (VR1, VR2) for ±5% adjustment.
It prevents damage from accidental detachment of sensing wires or incorrect voltage settings by gradually shutting down excitation voltage.
Check field polarity, ensure all terminals are connected, and if needed, perform field flashing by applying DC voltage to F+ and F− with a current-limiting resistor.
