Use

●For zone valves VVP.., VXP.., VMP..: compatible with SSB161.05UT

●Typically in chilled ceiling, VAV and fan coil unit applications

●Max.10 units of SSB161.05UT can operate in parallel, provided the controller output

suffices.

Technical design

When the actuator is driven by DC 0…10 V positioning signal, it produces a stroke, which is

transmitted to the valve stem.

DC 0…10 V positioning signal

●The valve opens / closes in proportion to the

positioning signal at Y.

●At DC 0 V, actuator stem is retracted, the normally

closed valve is fully closed.

●When there is no operating voltage, the actuator

maintains its current position.

Y = Positioning signal Y [V]

H = Percentage of calibrated valve stroke

Notes

Engineering

The actuators must be electrically connected in accordance with local regulations (see

"Connection diagrams [▶11]”).

CAUTION

National safety regulations

Failure to comply with national safety regulations may result in personal injury and property

damage.

●Observe national provisions and comply with the appropriate safety regulations.

Observe permissible temperatures (see "Technical data [▶9]").

Mounting

WARNING

●Do not use pipe wrenches, pliers or similar tools.

●Avoid lateral pressure or (cable) tension on the mounted actuator!

Valve and actuator are easy to assemble on site before commissioning:

●Remove protective cover from the valve body.

●Position the actuator and tighten the union nut manually.

●See "Mounting instruction" for graphical instructions.

Crimp ferrule on stripped wire of connecting cable.

●Observe all admissible temperatures (see "Technical data [▶9]").

●Do not twist the cable.

●Magnets can damage the actuator.

●Provide a means for isolation from the power supply, e.g., connecting a circuit breaker or

switch fuse upstream of the control unit.

CAUTION

National safety regulations

Failure to comply with national safety regulations may result in personal injury and property

damage.

●Observe national provisions and comply with the appropriate safety regulations.

CAUTION

Phase cut and pulse-duration-modulated (PDM) signals are not permitted.

Regulations and requirements to ensure the safety of people and property must be

observed at all times!

Commissioning

When commissioning, check wiring and functioning of the actuator.

●Actuator stem extends

Normally open valve closes, normally closed valve opens

●Actuator stem retracts

Normally open valve opens, normally closed valve closes

NOTICE

The actuator must be commissioned only with a correctly mounted valve in place!

Self-calibration

When operating voltage is applied, the actuator self-calibrates (fully retracted ➙fully

extended ➙setpoint).

CAUTION

Never intervene manually during self-calibration.

NOTICE

●Correct calibration is only possible with valve stroke > 1.2 mm. Valve stroke < 1.2 mm

results in calibration failure.

●If calibration fails, the actuator performs another calibration automatically after

10 seconds.

●After three failed calibration attempts, the actuator stem remains in the extended

position and the valves are closed. The state of the LED then changes to "stays red".

Manual operation

A 3-mm Allen wrench can be used to move the actuator to any position.

To move the actuator stem manually

1. Open the cover using a proper screwdriver.

2. Press and hold down button (a) illustrated below for at least three seconds.

–The actuator ignores any positioning signal from the controller.

3. Adjust the position of the actuator stem by rotating Allen wrench (b) illustrated below

clockwise or anti-clockwise.

–The actuator stem moves down if you rotate clockwise; it moves up if you rotate anti-

clockwise. The manually set position is retained.

4. To exit manual operation mode, press and hold down button (a) illustrated below again

for at least three seconds.

–The actuator runs a self-calibration automatically. Positioning signal sent from the

controller takes effect.

NOTICE

If operating voltage is applied to actuator, press button (a) before and after manually

adjusting the position of the actuator stem. If no operating voltage and positioning

signal are applied, manual operation can be done without pressing button (a).

Cabling operation

1. Unscrew cover screw

2. Remove cover

3. Connect or disconnect wire terminals

4. Install the cover

5. Screw in the cover screw

Maintenance

The actuators require no maintenance.
