scription of operation” section.

All related product regulations must also be adhered to. Changing or converting the product is not ad

missible.

Engineering and fitting notes

Do not use tools to fit the actuator to the valve. In the event of a power failure, the valve can be

opened by taking off the actuator. When connecting or changing the power cables, the mains power

must be switched off. The actuator may be fitted to the valve only when the actuator spindle is not

fully (100%) moved out. It is delivered ex works at 0% stroke.

Outdoor installation

We recommend protecting the devices from the weather if they are installed outside buildings.

Disposal

When disposing of the product, observe the currently applicable local laws.

Description of operation

Auto-calibration: During commissioning (with valve fitted), the spindle of the actuator moves com

pletely to the bottom (zero point). Then the spindle moves to the position that corresponds to the con

trol signal. Confirmation of the end position: When the actuator has been in its start or end position for

a lengthy period, every 2 hours the control signal is activated for around 60 seconds. This automati

cally recalibrates the actuator. The motor positions the valve and cuts out as soon as the stroke posi

tion matches the controller signal. The LED indicator lights up if power is applied and flashes as long

as the motor is running.

Direction of operation 1:

• As the positioning signal increases, the actuator spindle moves out and the VUL, VUT, VCL, VDL 2

way valves and the BUL 3-way valve (control passage) close. With the BXL 3-way valve, the control

passage opens.

Direction of operation 2:

• As the positioning signal increases, the actuator spindle moves in and the VUL, VUT, VCL, VDL 2

way valves and the BUL 3-way valve (control passage) open. With the BXL 3-way valve, the control

passage closes.

After the cap on the cover is removed, the following settings can be made using jumpers:

• Setting of the input signal. This can be set to either 0…10 V or 5.2…10 V or 0…4.8 V.

• Direction of operation 1 or 2 can be selected; the factory setting is direction of operation 2 (RA).

Put the cap back on after making the settings.
