Description of operation

When voltage is applied to the cable, the control unit to be activated is moved to any desired position

by means of the carrier stem.

Direction of rotation for 3-point control (viewing the spindle of the ball valve from the actuator):

• The stem turns in the anti-clockwise direction, with the voltage on the brown cable, and the through

passage of the ball valve is opened.

• The stem turns in the clockwise direction, with the voltage on the black cable, and the through pas

sage of the ball valve is closed.

With 3-point control, the direction of rotation is changed by swapping the connections.

Direction of rotation for 2-point control (viewing the spindle of the ball valve from the actuator):

There is always voltage on the black cable.

• The stem turns in the anti-clockwise direction, with the voltage on the brown cable, and the ball

valve is opened.

• The stem turns in the clockwise direction, with no voltage on the brown cable, and the ball valve is

closed.

In the end positions (limit stop in actuator), or in the case of an overload, the magnetic coupling is

activated. The positioning signal is switched off by the electronic cut-out after 3 minutes or 60 sec

onds (F100).

The manual adjustment is performed by releasing the gear unit (slide switch beside the connection

cable) and simultaneously turning it with the lever. The actuator position can be determined by look

ing at the lever or the indicator knob on the top part of the actuator

Intended use

This product is only suitable for the purpose intended by the manufacturer, as described in the “De

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

Condensate, dripping water, etc. must be prevented from entering the actuator along the carrier stem.

Hanging position (fitting upside down) is not admissible.

The actuator/ball valve is mounted by inserting and turning the bayonet ring until the limit stop without

any additional adjustment. No tools are required. The coupling of the spindle of the ball valve with the

carrier stem is performed automatically, either by moving the manual adjuster to an angle of rotation

of 100% or connecting the voltage to terminals MM/N and 01. For dismantling, the bayonet ring is

simply opened and the actuator removed. The device is delivered ex works in the middle position.

The concept of a synchronous motor with magnetic coupling is performed by electrically connecting

multiple rotary actuators of type AKM in parallel (only with accessory 0372459 10 . ).

If a potentiometer is required, the accessory of the AVM 105. 115 can be used – the direction of oper

ation on the type plate is inverted. The maximum accessory equipment for an actuator is 1 auxiliary

change-over contact or 1 potentiometer.

The auxiliary change-over contact accessory is screwed onto the top cover of the actuator. To be able

to make the mechanical connection, you first have to remove the indicator knob. A new indicator can

be seen on the cover of the accessory.

Note! The housing must not be opened.
