Connection
!CAUTION
Temporary 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 malfunc-
tions and damage.
NOTE
The actuation direction can be changed by switching the supply lines to terminals 2 and 3 on the
actuator or by setting DIP switch 3.

Q
Valve Installation
!CAUTION
The valve may only be installed by qualified technicians. In addition to the generally applicable instal-
lation guidelines, the following items are to be observed:
■The pipeline system and the fixture interior must be free of foreign objects. In the event of contam-
inated 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 actuator is kept
between 0 °C–+50°C.
■When carrying out installation, the permissible max. pressure difference p and the specified
direction of flow must be observed (see table in "Types" section, as well as the "Valve Principle").
■The three-way valves are to be used as mixing valves. Pay attention to the direction of flow (see
fig. "Valve Principle").
■Once the valve is installed, make sure the ball in the valve seating can be moved easily by pushing
in the valve stem.
■To install the actuator and remove the housing cover, approx. 170 mm of free space is required
above the actuator.
■Observe the direction arrow on the valve body. Inverting the direction of flow impairs control
behavior.

Q
Mounting and Commissioning the Actuator
!CAUTION
Do not electrically operate MD15-C, MD15-HR, MD15-DA Kleinstellantrieb without a valve.
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.

►Place the actuator on the threaded connection of the valve and tighten hand-tight using the union
nut.
►Establish the electrical connection.
►After the line power has been switched on, an automatic initialization run takes place. The
actuator first travels to the upper end position and then to the lower end position.
The actuator will not respond to the control signal until the initialization run is complete.

►Place the valve adapter onto the valve and tighten the hexagon socket screw
(see figure 5).
►Place the actuator on the threaded connection of the valve and tighten hand-tight using the union
nut (see figure 7).
►Establish the electrical connection.
►After the line power has been switched on, an automatic initialization run takes place. The
actuator first travels to the upper end position and then to the lower end position.
The actuator will not respond to the control signal until the initialization run is complete.
NOTE
When the unit is remounted, you must adapt the valves again by performing a reinitialization (see
page 14).
