ctuators for radiator valves with 2.5 mm nominal stroke 4 893 SS3... SS8... 8030 807 SS... without auxiliary switch SS... with auxiliary switch Electro-mechanical actuators for radiator valves. Nominal stroke range 2.5 to 5 mm utomatic stroke recognition 3-position or DC 0 0 V control signal C 24 V or C 230 V operating voltage Direct assembly with union nut (no tools required) Can be operated manually Optional auxiliary switch C 250 V / (0.5), with adjustable switching point 0...00 % Plug-in cable for supply voltage and control signal Parallel connection of multiple actuators possible With position indicator Use For use in heating systems in conjunction with radiator valves from Siemens or from other manufacturers. Functions The DC 0...0 V control signal or the 3-position control voltage generates a stroke in the actuator which is transmitted to the valve stem. SS3... / SS8... (3-position control) (DC 0...0 V control signal) Voltage at Y: Valve opens Voltage at Y2: Valve closes No voltage at Y and Y2: Valve remains in current position. The valve opens in proportion to the voltage at Y. t 0 V, the valve is closed. Type summary The basic types are supplied with a.5 metre cable, but actuators may also be ordered without a cable (type codes ending in.../00). long connecting cable (4.5 m, see ccessories ) can be ordered for these. The SS3... and SS8... actuators are also available with auxiliary switches. uxiliary switches ctuator types SS3... and SS8... have a built-in auxiliary switch. The switch cannot be fitted later.

3 mm Mechanical design Features: The actuator and valve are supplied separately. They are assembled with a union nut, requiring no tools or adjustments. In the case of actuators with auxiliary switches, the switch is connected to terminals and must be wired separately. Plastic housing Stall-proof gear unit, no maintenance required Plug-in connecting cable, length.5 m Non-interchangeable C 24 V and C 230 V sockets Manual adjustment with 3 mm llen key Reduced current consumption in stop positions Force-dependent switch-off in the event of overload, and in stroke end-positions. Up to 6 SS3 or SS8, or up to 0 SS6 actuators may be operated in parallel. 807 Engineering notes Note the admissible temperatures (see sections on Use and Technical data ). The connecting cable will not be damaged by contact with the valve body as long as the valve body temperature does not exceed 80 C. Mounting Orientation Mounting instructions are printed on the packaging. 8029 Permissible NOT permissible Commissioning When commissioning, check the wiring and the functioning of the actuator and auxiliary switch, if fitted. Spindle extended (movement from Mark 0 to ): Valve opens. Spindle retracted (movement from Mark to 0): Valve closes. Caution The calibrates itself (calibration stroke) during commissioning. Correct functioning cannot be guaranteed if the SS is operated without a valve. Operation The actuators can be driven manually to any position between 0 and with a 3 mm llen key. control signal from the controller, however, will take priority over any manual position. Note To hold the actuator in the manually set position, the connecting cable must be unplugged. 3 mm Manual adjustment with llen key B 809 8037 8036 0 0 3 mm B Position indicator at Mark 0 = CLOSED Position indicator at Mark = OPEN HVC Products 3/5
Maintenance When servicing the actuator note the following: Switch off the operating voltage. Where applicable, disconnect electrical connections from the terminals. The valve must be mounted in accordance with instructions before commissioning the actuator. Technical data Supply voltage SS3... SS8...
