!CAUTION

You require a 1 A pre-fuse to operate the electrical linear actuator.

!CAUTION

Peak loads of up to 10 A may occur when switching on the actuator. Ensure suitability of switching

components (e.g. controller connection) to ensure proper functioning and to avoid malfunctions and

damage.

NOTE

The actuation direction can be changed by switching the supply lines to terminals 2 and 3 on the

actuator.

MC15/230Product Description

Issue 2021-11-30

Valve Installation

■The pipeline system and the interior of the fitting must be free of foreign objects. In the event of

contaminated media, dirt collectors are to be inserted upstream of the valves with fine screens,

mesh width 0.25 mm.

■There must be no tension between the valve and the pipeline connection.

■To avoid eddy formations in the valve body, the valve should be installed in a straight section of

the pipe. A distance of 10 times the nominal diameter is recommended between the valve flange

and manifold or other similar parts.

■The installation location is to be selected so that the ambient temperature at the linear actuator is

kept between 0 °C and +50°C.

■When carrying out installation, the permissible maximum pressure difference p and the specified

direction of flow must be observed.

■The three-way valves are to be used as mixing valves. Observe the specified direction of flow.

■Once the valve is installed, make sure the ball in the valve seating can be moved easily by pushing

in the valve stem.

■For safety reasons, do not suspend the linear actuators from under the valve.

■Observe the direction of flow arrow on the valve body. Inverting the direction of flow impairs control

behavior.

Mounting and commissioning the linear actuator

WARNING

Contact with live parts of electrical domestic installation can cause death due to electric shock.

Mounting/removal may only be carried out when power is switched off.

CAUTION

Installation and commissioning work may only be carried out by qualified technicians.

If the valve is installed in the system, make sure that no differential pressure builds up in the valve

body before beginning work. If necessary, close the gate valve and turn off pumps. After the pipeline

has cooled off, the actuator can be installed.

Be sure to comply with VDE guidelines and local wiring regulations. The device is connected

according to the legally binding system circuit diagram.

!CAUTION

Do not operate the MC15/230 Small Actuator electrically without a valve.

►Place the linear actuator on the threaded connection of the valve and tighten hand-tight using the

union nut.

►Establish the electrical connection.

►When the power supply is switched on for the first time, an automatic initialization run takes place.

The actuator first travels to the upper end position and then to the lower end position. The valve

is then adapted.

The linear actuator does not respond to the control signal until the initialization run is complete.

►After mounting and commissioning work is complete, the automatic coupling must be protected

with the dust cover (see Fig. 8).

!CAUTION

After recommissioning or a manual adjustment, an initialization run must be triggered manually. This

is done by flipping the DIP switch before switching on the power supply (see Fig. 6).

Removing the linear actuator

CAUTION

Before beginning to remove the unit, make sure that no differential pressure builds up in the valve

body before beginning work. If necessary, close the gate valve and turn off pumps.

After the pipeline has cooled off, you can begin removing the linear actuator.

!CAUTION

Before beginning to remove the unit, put the actuator in the middle position.

►Move the linear actuator to the center position using a control signal.

►Disconnect the linear actuator from the mains power supply. Then disconnect all electrical

connections.

►Loosen the union nut.

►Turn the dust cover far enough so that you can press the safety button.

►Press the safety button on the automatic coupling all the way in and hold it (see Fig. 6).

►Remove the linear actuator from the valve.

Manual adjustment

!CAUTION

Manual adjustment may only be performed when the actuator is installed.

■The linear actuator must be disconnected from the mains power supply

for manual operation.

■A hexagon key (key socket 4 mm) can be used to move the actuator

into any position.

!CAUTION

If you manually adjust until the slip clutch responds, turn the hexagon key half a turn in the opposite

direction after the manually set stroke position has been reached.

NOTE

An initialization run must be performed after a manual adjustment, see Reinitialization section on p.10

Initialization and adjustment to the valve stroke

WARNING

Contact with live components of the building’s electrical system can cause death due to electric

shock.

The actuator must be disconnected from the power supply before you remove the terminal cover and

flip the switch.

Reinitialization

The valve stroke must be reinitialized whenever the unit is remounted

or adjusted manually.

►Disconnect the linear actuator from the power supply and remove

the terminal cover.

►Change the switch setting (1).

►Reattach the terminal cover and reconnect the power supply.

The linear actuator performs an initialization run.

NOTE

A valve stroke initialization is also performed when a valve end position is reached during normal

operation.
