3 Valves from other manufacturers To ensure trouble-free operation of third-party valves with the SSA actuator, the valves must satisfy the following requirements: F x y Threaded connections with coupling nut M30 x 15 ominal force 100 Dimension x (with valve fully closed) > 90 mm Dimension y (with valve fully open) 145 mm A M30 x15 AB Function / mechanical design When the actuator is driven by DC 0 10 V control voltage or by a 3-position signal, it produces a stroke which is transmitted to the valve stem The description of operation in this document applies to the valve versions which are fully open when deenergized (O) 3-position control signal SSA31 / SSA81 Voltage at 1: Stem retracts Valve opens Voltage at 2: Stem extends Valve closes o voltage at 1 and 2: Actuator maintains its current position DC 010 V control signal SSA61 Features and advantages The valve opens / closes in proportion to the control signal at At DC 0 V, the valve is fully closed (A AB) When power supply is removed, the actuator maintains its current position Locking-proof, maintenance-free gear train Reduced power consumption in the holding positions Load-dependent switch-off in the event of overload and in stroke limit positions Terminal block connectors for special cable lengths available (only for use with AC 24 V and AC / DC 24 V actuators) Connecting cables with AC 24 V and AC 230 V connectors cannot be mixed up 4893Z16 Accessories Adapter type AV for third-party valves Adapter types AV51 to AV61 are available for mounting the SSA actuators on thirdparty radiator valves as shown under «Type summary / accessories» Tamper-proof fitting AL Z x 1x a b a b tighten gently Building Technologies Electrical Actuators CE14893en HVAC Products /8

The permissible temperatures (refer to «Technical data») must be observed The connecting cable of the actuator may come into contact with the hot valve body, provided the temperature of the valve body does not exceed 80 C Actuator types SSA 311 and SSA811 have a built-in auxiliary switch The switch cannot be fitted in other actuators later The Mounting Instructions are enclosed in the product packaging Assembly is made with the coupling nut; no tools or adjustments are required The actuator must be fitted in position 1 (also refer to «Manual override»): Position the actuator and tighten the coupling nut manually Do not use any tools such as wrenches Avoid lateral pressure or (cable) tension on the mounted actuator! In the case of actuators without connecting cable (SSA/00), the separately ordered terminal block connector and connecting cable must be fitted Orientation Z01 Commissioning When commissioning, check the wiring and the functioning of the actuator and auxiliary switch, if fitted Actuator stem extends (from position 1 to 0): Valve closes Actuator stem retracts (from position 0 to 1): Valve opens 4/8 Building Technologies Electrical Actuators CE14893en HVAC Products

5 Self-calibration Caution During commissioning and every time power is applied to the SSA61, the actuator carries out a self-calibration (valve stroke 0 max setpoint) o manual interventions are permitted during calibration Correct calibration cannot be guaranteed if the SSA is operated without a valve The second calibration attempt is started automatically after a pause of 8 min After three calibration attempts, the valve stem remains extended Before fitting the actuator to the valve, power supply must be turned off and the valve stem brought to position 0 via manual control After the actuator is fitted and power supply switched on again, self-calibration will be repeated To ensure calibration can be performed, the valve used must have a minimum stroke of 15 mm If the valve s stroke is < 1,5 mm, the actuator/valve combination remains blocked after three calibration attempts (valve stem extended) When the Siemens VD, VE, VU, VPD and VPE radiator valves are combined with SSA61 actuators, the flow rate preadjustment must be set to 15 mm valve stroke If the valve travel is less than 15 mm, self-calibration is not possible and the valve with the acturator remains blocked The new Siemens valves VD, VE and VU have 15mm stroke at every preadjustment Operation ote A 3 mm hexagonal socket wrench can be used to move the actuator to any position between 0 and 1 However, if a control signal from the controller is present, then this takes priority in determining the position To retain the manually set position, unplug the connecting cable or switch off the operating voltage and the control signal Manual override 3 mm B A 1 3 mm mm 4893Z Z10 (, 1) A 4893Z08 B (, 2) Position indicator in position 1: Valve open Position indicator in position 0: Valve closed Maintenance Repair Disposal! The actuators are maintenance-free When carrying out service work on the plant, following must be noted: Turn power off (eg remove the plug) If necessary, disconnect electrical connections from the terminals The actuator must be commissioned only with a correctly mounted valve in place! SSA actuators cannot be repaired; the complete unit must be replaced The device must not be disposed of together with domestic waste This applies in particular to the PCB Legislation may demand special handling of certain components, or it may be sensible from an ecological point of view Current local legislation must be observed Warranty The technical data given for these applications is valid only when the actuators are used with the Siemens valves listed under «Equipment combinations» If the SSA actuators are used with other valves, then the user is responsible for ensuring correct functioning 5/8 Building Technologies Electrical Actuators CE14893en HVAC Products
