2 Selection of the flow direction of the valve
2.1 Normal flow direction (by default)
- Press the OPEN button and apply the operating voltage to the card while keeping this button pressed.
- The green LED lights up. Release the OPEN button.
- Disconnect the card.
2.2 Inverse flow direction
- Press the CLOSE button and apply the operating voltage to the card while keeping this button pressed.
- The red LED lights up. Release the CLOSE button.
- Disconnect the card.
3 Selection of the type of input control signal
3.1 Voltage control signal 0-10V
- Press the MEM button and apply the operating voltage to the card while keeping this button pressed.
- The red LED will light up 3 times. Release this button.
- Disconnect the card.
3.2 Current control signal 0-20mA
- This configuration can be performed only in our factory
3.3 Current control signal 4-20mA (by default)
- Press the MEM and CLOSE buttons and apply the operating voltage to the card while keeping these
buttons pressed.
- The red LED will light up 3 times. Release these buttons.
- Disconnect the card.
4 Learning mode
- Press the OPEN and CLOSE buttons and apply the operating voltage to the card while keeping these
buttons pressed.
- The 2 LEDs will light up. Release these buttons and the 2 LEDs will extinguish. The card is now in the
learning mode.
- Press the CLOSE button to put the valve in its closed position. The red LED will light up.
- Store this selected closed position by pushing MEM + CLOSE, the red LED will light up 2 times as a
confirmation of acknowledgement.
- Press the OPEN button to put the valve in its open position. The green LED will light up.
- Store this selected open position by pushing MEM + OPEN, the green LED will light up 2 times as a
confirmation of acknowledgement.
- Now, the positions selected have been stored. Disconnect the card.
NORMAL OPERATING MODE
- Apply the operating voltage to the card. The green LED will light up 3 times.
- Under normal operating conditions, the green LED will light up when the drive motor opens the valve,
and the red LED will light up when the drive motor closes it.
- If both LEDs remain extinguished, it means that the drive motor has not been triggered.
- In the case of an over torque, the motor stops and the 2 LEDS lights then together to indicate the action of the
torque limiter. To re-start it, you must either reverse the sense of rotation, either switch the power off and on.
