4 Learning mode
G R
- Press the OPEN and CLOSE buttons and apply the operating voltage to the card while keeping these but-
tons depressed.
- The 2 LEDs will light up. Release these buttons and the 2 LEDs will extinguish. The card is now in the
R
learning mode.
- Press the CLOSE button to put the valve in its closed position. The red LED will light up.
R
- Store this selected closed position by pushing MEM + CLOSE, the red LED will light up 3 times as a
confirmation of acknowledgement.
G
- 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 3 times as a
confirmation of acknowledgement.
G
- 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.
G
- 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.
G R
- 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
