Safety requirements
All installation and wiring work on the 3-way valve may only be carried
out in a zero volt state.
The opening, connection and commissioning of the device may only be
carried out by competent personnel. While doing so, they must observe
all local safety requirements.
This device is state of the art and meets all necessary safety regulations. It may only be used
in accordance with the technical data, safety requirements and regulations listed below.
When using the device, also observe all statutory and safety regulations apposite to the
particular use.
►The device may only be installed in a dry interior room.
►It must be possible to isolate the 3-way valve from the mains using an omnipolar isolating
facility.
►Before starting installation or wiring work, the 3-way valve must be completely isolated
from the mains and protected against reconnection.
►Safe operation is no longer possible if the 3-way valve exhibits visual damage, no longer
functions or has been stored for lengthy periods under unsuitable conditions. If this is the
case, disable the 3-way valve and secure against unintentional use.
Maintenance
The device does not require any maintenance and cannot be adjusted.
The design characteristics of the device must not be changed during repairs. Spare parts
must correspond to the original spare parts and must be used in accordance with the build
version.
Function
The UDV 3-way valve is a ball valve suitable for temperatures up to 100 °C with T-bore and
3/4" connections. The valve position is indicated on the casing.
Internal spring terminals permit free wiring in place of a fixed connection cable.
The valve may be switched both with relay changeover contact (3-point control signal), or
with continuous phase and N/O relay (2-point control signal, virtual return spring).
Internal coding and random positioning of the motor allows free selection of the hydraulic
paths (left-right, straight-left and straight-right).
All materials in the hydraulic area are approved for use with drinking water. However, it is not
DVGW-certified as a unit.

Valve:drive unit connection
Depending on requirements, the valve body can be connected to the drive in 4 different
positions. To secure this connection, the locking plate must be inserted into the slot provided
in the upper casing section.
Examples:
Camshaft
When positioning the camshaft on the valve shaft, ensure that the marking on the valve
shaft coincides with the marking at the lower end of the camshaft:
The marking on the valve shaft indicates the position of the ball valve.

7
If the camshaft is positioned correctly, then the indicator on the camshaft disc coincides with
the position of the ball valve:
Use of locking plate as a lever
The valve shaft can be brought into the correct position with the help of the locking plate. If
pliers are used, they could damage the valve shaft.
Selecting the rotation angle (90° or 180°)
The factory setting for the ball valve rotation angle is 180°. This rotation angle is determined
by the fixed control cam located on the shaft. In its end positions, this control cam actuates a
limit switch, thereby switching off the drive motor.

If a switching angle of 90° is required, then a second control cam must be inserted into the
shaft. To do this, break the control cam (coloured grey in the drawings) out of the disc and
slide it into the groove provided for this purpose.
View of the correctly inserted 90° control cam
If the control cam has been broken out, but is no longer required, then it can be twisted by
180° and inserted into the groove, so that it can no longer actuate the limit switch:

Control cam valve position indicator
When the upper casing section is attached, the current position of the valve is indicated by
the camshaft disc. In the following example, the upper part of the "cross" is red, which
means that this branch is closed.
The position of the
spherical head is therefore:

10
Mounting the drive motor
To connect the drive motor to the camshaft, insert the drive shaft into the motor shaft. Then
secure the motor to the lower casing section with 2 fixing screws.
The motor is connected to the motor terminals at the factory. These connections must not be
interchanged.

Electrical connection
The valve may be switched both with relay changeover contact (3-point control signal) or with
continuous phase and N/O relay (2-point control signal, virtual return spring).
3-point control signal
In this case, one core is responsible for clockwise rotation and another for anti-clockwise
rotation. Consequently, 3 wires are required for switching the valve.
No earth connection is required, because the drive unit is safety insulated.

2-point control signal
A continuous voltage is required at the valve for operation with a 2-point control signal. This
causes the motor to be rotated clockwise into its end position.
The Y control phase uses an integrated relay to switch the rotational direction to anti-
clockwise and the motor rotates to its other end position. If this Y control phase is switched
off again, the motor rotates clockwise back to the other end position ("virtual return spring").
Normally, a wire jumper needs to be established from above across the neutral connection
and the second terminal.
No earth connection is required, because the drive unit is safety insulated.
An external voltage may also be used for switching, if it cannot be ensured that the Ycontrol
phase has the same phase angle (L1, L2, L3) as the continuous phase or originates from the
same electrical circuit:

This declaration certifies conformity with the listed directives, but does not guarantee any properties.
The safety instructions in the product documents supplied must be observed.

Guarantee conditions
Note: The following guarantee conditions do not limit the statutory right to a warranty, but
rather expand your consumer rights.
1. Technische Alternative RT GmbH provides a two-year guarantee from the date of purchase to
the end user for all devices and parts it sells. Defects must be reported immediately upon
detection and within the guarantee period. Technical support can supply the correct solution
for almost every known problem. In this respect, contacting us immediately will help to avoid
unnecessary expense and effort in troubleshooting.
2. The guarantee includes free repair (but not the cost of on-site fault finding, removal, refitting
and shipping) due to operational and material defects which impair the function. In the event
that a repair is uneconomical in the opinion of Technische Alternative for reasons of cost, the
goods will be replaced.
3. Excluded is damage resulting from the effects of a voltage surge or abnormal ambient
conditions. Likewise, no liability can be accepted if the device defect is due to: transport
damage for which we are not responsible, incorrect assembly and installation, incorrect use,
failure to observe the operating and installation instructions or incorrect maintenance.
4. The guarantee will become void if repairs or actions are carried out by people who are not
authorised to perform them or have not been so authorised by us, or if our devices are
operated with spare parts, auxiliary parts or accessories that are not considered to be original
parts.
5. Faulty parts must be returned to our factory with a copy of the proof of purchase and a precise
fault description. Processing is accelerated if an RMA number is requested via our homepage
www.ta.co.at.The defect must be clarified with our technical support beforehand.
6. Services provided under guarantee result neither in an extension of the guarantee period nor
in a commencement of a new guarantee period. The guarantee period for fitted parts ends
with the guarantee period of the whole device.
7. Further or other claims, especially those for compensation for damage other than to the device
itself, insofar as such liability is not required by statute, are excluded.
