2.2 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 4-20mA (GPS only)
Press the MEM and OPEN 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.
3.3 Current control signal 4-20mA (by default / except GPS)
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 run out. 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 ran out, 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.
