2.7 Product replacements
Replacement of SQS../SSC.. actuators by SAS.. and SAT.. actuators.
·When replacing actuators consider positioning force.
·Adjust in the controller the parameter "Running time" (corresponds to positioning
time + idle stroke) and "Positioning time" if changed, to ensure stable control.
·The replacement of accessory items needs to be taken into consideration also.
In that case, compatibility is not necessarily ensured.

2.7.2 Electrical accessories
·If auxiliary switches are used, their switching points should be indicated on the
plant schematic.
·Do not insulate the yoke and housing of the actuator and the valve stem, as air
circulation must be ensured.
·Non-observance of the above may result in accidents and fires!
·Do not touch the hot parts without prior protective measures to avoid
burns!

2.9 Sizing
2.9.1 Parallel operation of actuators
3-position actuatorsmust have one specific controller each; refer to chapter
6.3 Connection diagrams (page 50).
Up to 10 actuators can drive in parallel on a controller output with a rating of 1 mA.
Modulating actuators have an input impedance of 100 kΩ.
2.9.2 Permissible cable length and wire cross-sectional area
Cable lengths and wire cross-sectional areas depend on the following criteria of the
actuators:
·Current draw
·Permissible voltage drop across the power supply lines
The control accuracy of the modulating actuators can be improved by using 4-wire
connections, thus ensuring that voltage drops on G0 will not distort the positioning
signal.
When determining the cable length and the wire cross-sectional area, adherence to
the permissible operating voltage tolerance at the actuator is of importance, in
addition to the permissible voltage drop across the operating voltage and signal
lines (see table below).
Product
no. Operating voltage Terminal Max. permissible voltage drop
SA..31.. AC 230 V N, Y1, Y2 2% each (total of 4%)
SA..61.. AC/DC 24 V G0, Y, U 1% each (at DC 0…10 V)
SA..81.. G, Y1, Y2 4% each (total of 8%)
The following criteria must be considered:
·With modulating control, the permissible positioning signal error must not exceed
1%, the reason being the voltage drop on the G0 wire.
·The voltage drop, caused by charging current peaks in the actuator’s DC circuit,
must not exceed 2 Vpp.
·If the G0 line is not correctly sized, load changes of the actuator due to changes
of the DC voltage drop might lead to self-oscillations.
·The operating voltage drop at AC/DC 24 V may be a maximum of 8% (4%
across the G0 wire).

sectional areas.

in W.

2.10 Warranty
The engineering data specified in chapter 2.5 Equipment combinations (page 10)
are only guaranteed in connection with the Siemens valves listed. Siemens rejects
any and all warranties in the event that third-party products are used.
When using the actuators in connection with valves of other manufacture, correct
functioning must be ensured by the user, and Siemens will assume no
responsibility.

3.1.3 Accessories
Before fitting the accessory items shown below, the following steps must be
performed:
1. Actuator is mechanically connected to a Siemens valve.
2. Observe compatibility and choice of combinations. Refer to 2.6 (page 11).
3. Disconnect actuator, auxiliary switch from power.
Attention if AC 230 V connected danger of life!
4. Only required with actuators without fail safe function: Using the manual
adjuster, drive the actuator’s stem to the fully retracted position and fix the
coupling. See “Manual operation” and “Fixing the position” (page 42).
5. To fit an auxiliary switch the housing cover must be removed and the M16
knock-out broken out.
