Type A: Switch type with source light indicator signal
The valve opening and closing operation is realized through the switch circuit, and a set of active position signals indicating the valve is fully open and fully closed is output.
Wiring instructions:
1. Terminal 1 is connected to the neutral line of the power supply;
2. When the power phase line and terminal 2 are connected, it is "on" and runs until the stroke switch OLS acts;
3. When the power phase wire is connected to terminal 3, it is "off" operation, until the travel switch CLS acts;
4. When the power phase line and terminal 2 are connected, it is "open". When the operation is in place, the "full open signal" indicator light connected to terminal 4 is on;
5. When the power phase wire is connected to terminal 3, it is "off". When the operation is in place, the "full off signal" indicator light connected to terminal 5 is on.
