MODULATING DAMPER ACTUATOR
STCZ-43
DATASHEET
ELECTROMAGNETIC DAMPER ACTUATOR STCZ-43
WITH ROTARY MOVEMENT FOR MODULATING CONTROL
The damper actuator is designed to operate dampers or mixing
sections inside air handling units or general dampers in
ventilation and air conditioning systems.
The damper actuator is controlled by an external 0...10 VDC
signal and equipped with an internal overload protection mean-
ing that energi consumption in end positions will be reduced.
INTERNAL OVERVIEW
POTENTIOMETERS
There are two potentiometers. These are not used and should
be left in end positions.
- O shall be in 0-position
- S shall be in 10-position.
DISCLAIMER
If DIP-switch 1 or positions of potentiometers are altered we
don't guarantee correct functionality of the control system.

ROTATION
With DIP-switch 2 it's possible to reverse rotation. Change it
and you will get reversed operation of the damper according to
input signal.
COMMISSIONING
Check that the actuator is properly wired. Depending of installa-
tion the actuator is connected directly to control equipment or to
a Modbus module, STCZ-70.
Disposal
The devices are considered electronics
devices for disposal in term of European
Directive 2012/19/EU and may not be
disposed of as domestic waste.
• Dispose of the device via the channels provided for
this purpose.
• Comply with all local and currently applicable laws
and regulations.

Siemens2- and 3-port valves with flanged connections, PN 16 CE1N4403en
Building Technologies 2014-03-27
Engineering notes
Preferably mount the valves at the return, as the temperature is lower there and
the strain on the stem sealing gland is lower.
Mount a dirt filter or dirt trap before the valve to ensure proper functioning, and a
long service life of the valve. Remove dirt, welding beads, etc. from the valves and
pipes.
Cavitation can be avoided by limiting the pressure differential across the valve
depending on the medium temperature and prepressure.
Mounting notes
Indoors Outdoors
Mounting positions apply to both 2- and 3-port valves.
Commissioning notes
The valve may be put into operation only if actuator and valve are correctly
assembled.
Ensure that actuator stem and valve stem are rigidly connected in all positions.

Maintenance notes
The valves are maintenance-free.
When servicing valves or actuators:
· Deactivate the pump and turn off the power supply
· Close the shutoff valves
· Fully reduce the pressure in the piping system and allow pipes to completely
cool down
If necessary, disconnect the electrical wires.
Due to the different types of material used, the valve must be disassembled prior to
disposal. Special handling of certain valve components may be required by law or
may be sensible from an ecological point of view.
Local and currently valid legislation must be observed.
