    English 1 SAFETY This device complies with current applicable safety standards. The installation, use, and maintenance, of this unit require a skilled and trained staff. Please carefully read this entire document before mounting and starting-up the actuator. 2 PACKAGING, STORAGE AND MAINTENANCE 2.1 Packaging &...

  • Page 5: Mechanical Set-Up

    English 3 MECHANICAL SET-UP After assembly on the valve or the damper, the actuator can operate in any position. However: • It is not recommended to install the actuator with its  cover facing downwards. • The cable glands must not be oriented upwards (loss of water tightness).

  • Page 6: Configuring Position Indicator For Counterclockwise Closing

    English 3.2 Configuring position indicator for counterclockwise closing As a standard, AQL actuators are configured to close clockwise. If the actuator must close counterclockwise, you can change the orientation of the position indicator cap. Standard indicator orientation Reverse indicator orientation for for clockwise closing counterclockwise closing How to change cap orientation...

  • Page 7: Adapting The Actuator To Your Valve Input

    English 3.3 Adapting the actuator to your valve input  Both the actuator and the valve must be in the same position, either fully open or fully closed. 3.3.1 Adapters The actuator is supplied with a set of adapters to ensure the output fits your valve shaft.

  • Page 8: Fastening The Actuator On The Flange

    English 3.3.2 Flange spacer (OPTION) If the valve input rod is too long and does not allow you to mount the actuator on the valve flange, you can mount a spacer under the actuator. This spacer is assembled on the flange of the AQL as shown below. 3.4 Fastening the actuator on the flange Once the actuator is coupled with the valve, you need to fasten it on the valve flange.

  • Page 9: Electrical Connection And Tests

    English 4 ELECTRICAL CONNECTION AND TESTS To perform the electrical wiring, please refer to the wiring diagram stuck inside the actuator cover and follow the numbering of the terminals. Make sure not to wire an AC supply on terminals A, B, C or a DC supply on terminals 1, 2, 3, this would damage the board.

  • Page 10: Installation Of The Fast Connector (Option)

    English 4.2 Installation of the Fast Connector (OPTION) Bernard Controls provide a fast connector option for AQL actuators. With this option, the male fast connection socket should be connected to the actuator terminals inside the actuator. Sealing must be done using the provided M20 cable gland.

This operation must be carried out by a qualified electrician. proportional transmitter board allows you to get a feedback of the current position...
  • Page 12 English The yellow LED starts blinking. When the actuator reaches the CLOSED position, press on SW1 to validate this position as the CLOSED position. The yellow LED remains ON. Check that the position transmission operates correctly by measuring the current intensity between terminals 32 & 33. ...

  • Page 13: Calibration Of Positioner Board (Option)

    English 5.2 Calibration of positioner board (OPTION) Make sure that the board is connected to the power supply during the calibration process. This operation must be carried out by a qualified electrician. The proportional analog command allows you to drive valve intermediate positions.
  • Page 14 English 5.2.2 How to set the positioner board The potentiometer has mechanical stops, be careful not to  turn the actuator too much on one side. Check that the screw of the pinion on the potentiometer is not too loose. Press for 5 seconds on the SW1 push button located on the board.
  • Page 15 English How to set closing direction and fail position You can use the SW2 dip switches to set the closing direction (dip switch C) and the fail position (dip switches A & B) in case of signal loss. This setting must be done with the power off. Closing Fail direction...

  • Page 17 English How to adjust a single cam Make sure that the cam operates the lever in the right  direction (as shown by the arrow in the figure below), otherwise the switch could be damaged. At the desired position of the actuator output: 1) Turn the setting screw of corresponding with a screwdriver.

  • Page 18: Resuming Calibration Of Travel Limits

    English 6.3 Resuming calibration of travel limits Travel limit settings are done with cams only. The actuator stops on the open or closed position when the travel limit switch is tripped. Remove the cover and, after the power supply is connected, proceed to the following test.
  • Page 19 English How to test factory settings (with positioner) Using the manual override, drive the actuator in the clockwise direction to the end position. According to the situation: • If the end position cam trips the switch at the same time as the valve is closed, you do not need to resume the settings.
