Use
●For 2-way and 3-way Powermite 599 MT Series, 599-02000 - 599-02079
●Typical application in chilled ceiling, VAV, unit ventilators, fan coil unit and other terminal
unit applications
●Max.10 units of SSC161.05DU, SSC161S.35DU are able to operate in parallel, provided
the controller output suffices.
●For 3-position actuator, SSC131.39U, 24 actuators can run in parallel.
NOTICE
●SSC131.39U floating fail-safe actuators cannot be run in parallel with legacy SSC81.5U
actuators.
●For parallel operation of floating fail-safe SSC actuators all actuators in parallel must be
the same part number.
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.
3-position control signal (for SSC131.39U only)
●Voltage at Y1:
Stem extends
Normally open valve
closes, normally closed
valve opens
●Voltage at Y2:
Stem retracts
Normally open valve
opens, normally closed
valve closes
●No voltage at Y1 or Y2:
Actuator maintains its current position
●Voltage applied to both Y1
and Y2 (not recommended):
When no power is supplied, the
SSC131.39U actuator fails with
the stem fully retracted.
Stem moves to Y2

DC 0...10 V control signal
●The valve opens / closes in proportion to the
control signal at Y.
●At DC 0 V, actuator stem is retracted, the normally
closed valve is fully closed and the normally open
valve is fully open.
●When no power is supplied, the SSC161.05U
actuator maintains its current position and the
SSC161.35U actuator fails with the stem fully
retracted.
●This actuator provides a DC 0…10 V position
feedback signal proportional to the stroke of the
actuator stem.

Notes
Engineering
The actuators must be electrically connected in accordance with local regulations (see
"Connection diagrams [▶14]”).
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 [▶10]").
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 connection nut manually.
●See "Mounting instruction" for graphical instructions.
Orientation
Commissioning
When commissioning, check both 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!

Siemens
A6V12681517_enUS_a
Smart Infrastructure
02/09/2023
Self-calibration
When operating voltage is applied, the actuators self-calibrate (fully retracted ➙fully
extended ➙setpoint).
CAUTION
Never intervene manually during self-calibration.
NOTICE
●Correct calibration is only possible with valve stroke > 0.05 inch (1.2 mm). Valve stroke
< 0.05 inch (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 open.
Electrical fail-safe function (for SSC161.35U, SSC131.39U only)
When first connected to power, or after a power failure, the capacitor which stores energy for
the fail-safe function will be charged. This process takes up to 180 seconds. While the
capacitor is being charged, the actuator cannot respond to any control signals.
In the event of a power failure of more than 5 seconds, the actuator will return to its fail-safe
position within 30 seconds.
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 control signal from the controller.

3. Adjust the position of the actuator stem by rotating Allen wrench (b) illustrated below
clockwise or counter-clockwise.
–The actuator stem moves down if you rotate clockwise; it moves up if you rotate
counter-clockwise. The manually set position is retained.
4. To release the actuator from manual operation mode, press and hold down button (a)
illustrated below again for at least three seconds.
–The actuator runs a self-calibration automatically. Control signal sent from the
controller takes effect.
5. Close the cover.
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 control signal are
applied, manual operation can be done without pressing button (a).
Cabling operation
1. Unscrew cover screw
2. Remove cover
3. Remove terminal block and connect or disconnect wire terminals.
4. Re-install the terminal block
5. Install the cover
6. Screw in the cover screw
Maintenance
The actuators require no maintenance.

WARNING
Operating voltage must be switched off during any maintenance!
NOTICE
When carrying out service work on the plant, note the following:
●Switch off operating voltage.
●If necessary, disconnect electrical connections from the terminals.
●The actuator must be commissioned only with a correctly mounted valve in place!
Repair
The actuators cannot be repaired; the complete unit must be replaced.
Disposal
The device is considered an electronic device for disposal and may not
be disposed of as domestic waste.
●Dispose of the device through channels provided for this purpose.
●Comply with all local and currently applicable laws and regulations.
