Reversing Actuators
Siemens Building Tec nologies, Inc.
Description SQM5... reversing actuators are used for t e positioning of flow control valves, butterfly
valves, dampers, or any application requiring rotary motion. T e SQM5… actuators
accommodate control input signals of 4 to 20 mA, 0 to 135 , 0 to 10 Vdc, 0 to 20 mA,
position proportional and floating control. T e available output signals include
4 to 20 mA, 0 to 135 , 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 . SQM5… actuators
are available wit up to six internal, easily adjustable switc es.
A selection of exc angeable circuit boards provide a variety of functions including
auto/manual selector switc , manual forward/reverse toggle switc , zero and span
adjustment, parallel or master/slave operation, split range control, input signal override,
and selectable electronic linearization.
T e SQM5… is engineered for precision. It is particularly well suited for applications
requiring a ig degree of modulating accuracy and repeatability.
T e SQM5… actuator may be mounted in any position. A selection of mounting
brackets and s afts provides installation flexibility and allows for t e simple replacement
of most competitive actuators.
Features  Two limit switc es, plus up to four internal auxiliary switc es
 Fully closed “economy position” switc
 Drive s aft and cam drum disengagement clutc es

Application SQM5… actuators are uniquely suited for bot industrial and commercial
applications. T e ig level of accuracy permits precise modulating control of
industrial process and process eating applications, often significantly en ancing
performance and product quality.
In commercial and industrial burner applications requiring ig turndown and
reliable ignition, t e auxiliary switc es can be applied to create separate positions
for burner ignition and low fire. In dual fuel applications, additional switc es can be
used to create separate ig fire, low fire and ignition positions for eac fuel. T e
economy position switc is used to drive t e actuator to t e full closed position
w en t e burner is off.
In all applications, commissioning is simplified. S aft and cam drum disengagement
clutc es allow for t e quick manual alignment of t e actuator s aft and switc
cams. T e forward/reverse toggle switc in combination wit t e auto/manual
selector switc provides direct manual control.

NOTE: T e actual minimum and maximum
modulating range is determined eit er
by t e setting of t e MIN and MAX trim
potentiometers or t e setting of switc

circuit board provides t e following features:
Multiple Input Signals T e AGA56.9A… circuit board accepts t e following input signals:
Line voltage
 Power to A drives t e actuator open to t e setting of switc cam I (Maximum).
 Power to ZL drives t e actuator closed to t e setting of switc cam III (Minimum).
 Power to Z drives t e actuator closed to t e setting of switc cam II (Economy).

Electronic Linearization
Function Butterfly valves ave non-linear flow c aracteristics. Near t e fully closed position, a small
c ange in t e valve’s position will produce a very large c ange in flow. Near t e fully open
position, a large position c ange will produce a relatively small c ange in flow.
T e linearization function is intended to minimize t e initial steep flow curve
c aracteristics of a typical butterfly valve. T e linearization function is enabled w en
Jumper J1 is in position 1 (upper position). Consequently, t e actuator will make smaller
rotational movements w en subjected to lower input signals and larger rotational
movements w en subjected to ig er input signals.
For example (based on a 90 modulating range), a c ange in input signal from 4 to 8 mA
will cause a rotational movement of 11.25. An equal c ange from 16 to 20 mA will cause
a rotational movement of 45. T us, wit t e linearization function enabled, t e c ange in
flow is closely proportional to t e c ange in input signal.
T e linearization function is disabled w en Jumper J1 is in position 2 (lower position).
W en disabled, t e rotational movement of t e s aft is proportional to t e input signal.
Input Signal Overri e Line voltage to terminal P will drive t e actuator to a pre-set adjustable position,
overriding all modulating input signals. Use t e potentiometer marked POS to adjust t e
override position to any setting wit in t e setting range of switc cams I and III.
NOTE: T e input
signal override can also be used for t e ignition position of burners if different
from t e low fire position.
Parallel Operation Set Jumper J2 in position 1 (upper position) to configure t e actuator for parallel
operation. Input signals Y0, Y1, Y2 or Y3 are directly s unted to output signals U1, U2
and U3. All output signals are available regardless of w ic input signal is applied.
Master/Slave Operation Set J2 in position 2 (lower position) to configure t e actuator for master/slave operation.
T e output signals U1, U2 and U3 reflect actual s aft position.
Split Ranging AGA56.9… circuit boards ave a modulating signal s ift feature w ic can be used for
split ranging. If no signal is present on Y0, Y1, Y2 or Y3, t e actuator will modulate
t roug t e full rotational range in response to a 12 to 20 mA signal applied at ZF. If a
maximum signal is present on Y0, Y1, Y2, or Y3, t en t e actuator will modulate t roug
t e full rotational range in response to a 4 to 12 mA signal applied at ZF. (Maximum
signal can be easily ac ieved by bridging terminals U4 and Y0.) See Figure 16.
NOTE: It is possible to configure t e actuator for split range operation 12 to 4 mA and
20 to 12 mA. Consult your aut orized Siemens Building Tec nologies
combustion products sales representative for details.
