Dimensions

Connection

| 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.

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 recommendedbetween 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 iskept 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 behavi r.

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 protectedwith 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 supplyfor 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.
