• The device must not be used outside the specified field of application, especially not
!
in aircraft or in any other airborne means of transport.
• Outdoor application: only possible in case that no (sea)water, snow, ice, insolation
or aggressive gases interfere directly with the actuator and that is ensured that the
ambient conditions remain at any time within the thresholds according to the data
sheet.
• Only authorised specialists may carry out installation. All applicable legal or
institutional installation regulations must be complied during installation.
• The device may only be opened at the manufacturer's site. It does not contain any
parts that can be replaced or repaired by the user.
• Cables must not be removed from the device.
• The rotary supports and coupling pieces available as accessories must always be
used if transverse forces are likely. In addition, the actuator must not be tightly bolted
to the application. It must remain movable via the rotary support (refer to «Assembly
notes»).
• If the actuator is exposed to severely contaminated ambient air, appropriate
precautions must be taken on the system side. Excessive deposits of dust, soot etc.
can prevent the gear rod from being extended and retracted correctly.
• If not installed horizontally, the gear disengagement pushbutton may only be
actuated when there is no pressure on the gear rod.
• To calculate the actuating force required for air dampers and slide valves, the
specifications supplied by the damper manufacturers concerning the cross section,
the design, the installation site and the ventilation conditions must be observed.
• If a rotary support and/or coupling piece is used, actuation force losses are to be
expected.
• The device contains electrical and electronic components and must not be disposed
of as household refuse. All locally valid regulations and requirements must be
observed.
The actuator is connected with a standard modulating signal of DC 0...10V and drives
to the position defined by the positioning signal. Measuring voltage U serves for the
electrical display of the damper position 0...100% and as slave control signal for other
actuators.
The factory settings cover the most common applications. Single parameters can be
modified with the Belimo Service Tools MFT-P or ZTH EU.
The actuator can be directly connected with the application using the enclosed screws.
The head of the gear rod is connected to the moving part of the ventilating application
individually on the mounting side or with the Z-KS2 coupling piece provided.
Manual override
Manual override with push-button possible (the gear is disengaged for as long as the
button is pressed or remains locked).
If a stroke limitation will be adjusted, the mechanical operating range on this side of
the gear rod can be used starting with an extension length of 20 mm and then can be
limited respectively in increments of 20 mm by means of mechanical end stops Z-AS2.
