2.7 Product replacements
Replacement of SQX.. / SQL.. actuators by SAX.. / SAL.. actuators.
•When replacing actuators consider positioning force, torque and positioning
times.
Note
•Adjust in the controller the parameter "Running time" respectively "Positioning
time", to ensure stable control.
•The replacement of accessory items needs to be taken into consideration also.
In that case, compatibility is not necessarily ensured.

Note
2.7.3 Electrical accessories
•If an auxiliary switch is required, its switching point should be indicated on the
plant schematic.
Notes
•For media below 0 °C the stem heating element ASZ6.6 keeps the valve free
from freezing.
•For this case, do not insulate the actuator bracket 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 actuators must have one specific controller each, refer to "Connection
diagrams" (page 54).
SA..31.. and SA..81..
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 k.
SA..61..
2.9.2 Permissible cable lengths and wire cross-sectional
areas
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).

1% each (at DC 0…10 V)
SA..81..

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% above
the G0 wire).

2.10 Warranty
The engineering data specified in chapter "Equipment combinations" (page 10) are
only guaranteed in connection with the Siemens valves listed.
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.
