Description  
SQM5... reversing actuators are used for the positioning of flow control valves, butterfly  
valves, dampers, or any application requiring rotary motion. The SQM5… actuators  
accommodate control input signals of 4 to 20 mA, 0 to 135 Ω, 0 to 10 Vdc, 0 to 20 mA,  
position proportional and floating control. The available output signals include  
4 to 20 mA, 0 to 135 Ω, 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 Ω. SQM5… actuators  
are available with up to six internal, easily adjustable switches.  
A selection of exchangeable circuit boards provide a variety of functions including  
auto/manual selector switch, manual forward/reverse toggle switch, zero and span  
adjustment, parallel or master/slave operation, split range control, input signal override,  
and selectable electronic linearization.  
The SQM5… is engineered for precision. It is particularly well suited for applications  
requiring a high degree of modulating accuracy and repeatability. Drive shaft play is  
limited to 0.3° with a modulating accuracy of 250 repositions through 90° of travel.  
The SQM5… actuator may be mounted in any position. A selection of mounting  
brackets and shafts provides installation flexibility and allows for the simple  
replacement of most competitive actuators.

SQM5… Reversing Actuators  
Actuator model numbers that end with “R” are factory configured for clockwise (cw),  
minimum to maximum rotation when facing the gear end of the actuator, or  
counterclockwise (ccw) rotation when facing the other end of the actuator. The gear end  
of the actuator is the side opposite of the visual position indicator.  
Rotational Direction  
Verification  
To field reverse the direction of rotation, see Service Guide, “Reversing Rotational  
Direction”.  
Actuator Mounting  
SQM5… actuators can be mounted in any orientation using the four 1/4"-20 UNC  
tapped holes located on the bottom corners of the actuator base. Optional base  
mounting brackets are available. See Table 2.  
SQM5… actuators can also be face mounted using self tapping screws in combination  
with the various holes on the face of the actuator gear end.

Switch Adjustment  
All SQM5…actuators are factory wired with Switch I (maximum), Switch II (fully closed  
“economy position”) and Switch III (minimum). The individual switch cams I, II, and III  
are factory set to 90°, 0° and 10° respectively.  
See Figure 6.  
NOTE: The single switch cam pointers are used together with the black scales when  
configured for counterclockwise (ccw) operation.  
The double switch cam pointers are used together with the red scales when  
configured for clockwise (cw) operation.  
The individual switch cams can be adjusted by hand or with the use of the tool  
attached to the outside of the hinged switch terminal protection lid.

Switch Adjustment,  
Continued  
NOTE: If a potentiometer is installed, the adjustable range of the switches depends  
on the range of the potentiometer.  
SQM5x.xxxxxAx actuators may be adjusted between 0° and 160°.  
SQM5x.xxxxxx3 actuators have a 90° potentiometer and the switches must be  
adjusted only between 0 and 90°.  
SQM5x.xxxxxx4 actuators have a 135° potentiometer and the switches must  
be adjusted only between 0 and 135°.  
Shaft Adjustment  
The actuator shaft can be disengaged by pressing the silver shaft release button. The  
button is located above the grounding screw, under the hinged terminal protection  
cover, and to the right of the auto/manual switch. After pressing the shaft release button  
in and slightly upward, the shaft can be manually rotated. After the shaft has been  
manually aligned to the closed position, re-engage the shaft by pushing the shaft  
release button downwards.  
See Figure 6.  
Once the shaft has been set, the cam drum must be manually aligned by pressing and  
holding the black cam drum release button (see Figure 6). Rotate the cam drum until  
the “0” mark on the actuator position scale (left scale on the cam drum) is aligned with  
the gray actuator position indicating pointer.  
Cam Drum Adjustment  
See Figure 6.  
Position Indicating Dial  
Adjustment  
The actual position of the SQM5… actuator is indicated by the gray actuator position  
indicating pointer (see Figure 6). The position is also displayed by the indicating dial  
through the housing’s window. Ensure that the actuator position indicating dial is  
aligned with the actuator position scale. If necessary, rotate the dial in the clockwise  
direction.  
CAUTION:  
Turning the dial in the counterclockwise direction may loosen the  
potentiometer locking screw.  
Wiring  
SQM5… actuators are equipped with two removable conduit connection plates located  
on the upper corner of the gear housing. Each plate is provided with two threaded  
connections for 1/2" NPSM conduit connectors. The use of flexible stranded wire is  
recommended.  
Electrical Connection  
Grounding  
CAUTION:  
To avoid electro-magnetic interference, the SQM5… actuators must be  
grounded.  
The ground terminal is located to the right of the auto/manual switch.  
Disconnect the circuit board wire marked 51 during high voltage testing.  
Reconnect it to the grounding terminal after the test.

SQM5… Reversing Actuators  
Wiring Connections  
NOTE: SQM5… actuators require a single source, single phase power supply.  
Wiring connections vary depending on which AGA56…. circuit board is installed.  
AGA56.1… circuit boards.  
Manual Operation  
See Figures 7 and 8.  
1. Set the AUTO/MAN switch in the MAN position.  
2. Connect ground to the screw located below the shaft release button.  
3. Connect neutral to the double terminal block, located on the left side of the gray  
switch housing.  
4. Only terminal "L" must be to enable manual operation. The actuator can now be  
driven to the maximum position (switch cam I) or the fully closed "economy  
position" (switch cam II) by using the toggle switch located to the left of the  
AUTO/MAN switch.  
Automatic Operation  
1. Set the AUTO/MAN switch in the AUTO position.  
2. Connect ground to the screw located below the shaft release button.  
3. Connect neutral to the double terminal block located on the left side of the gray  
switch housing.  
4. Connect line voltage to terminal A to drive the actuator in the opening direction.  
5. Connect line voltage to terminal Z to drive the actuator in the closing direction.  
CAUTION:  
Do not power terminals A and Z simultaneously. Actuator damage will occur.

Circuit Boards.  
1. Set the AUTO/MAN switch in the MAN position.  
2. Connect ground to the screw located below the shaft release button.  
3. Connect neutral to terminal N.  
See Figures 9 and 10.  
4. Only terminal "L" must be powered to enable manual operation. The actuator can  
now be driven to the maximum (high fire) position (switch cam I) or the fully closed  
"economy position" (switch cam II) by using the toggle switch located to the left of  
the AUTO/MAN switch.  
Automatic Operation  
1. Set the AUTO/MAN switch in the AUTO position.  
2. Connect ground to the screw located below the shaft release button.  
3. Connect neutral to terminal N.  
4. Connect line voltage at all times to terminal L to provide power to the electronic  
circuit board.  
5. Connect line voltage to terminal LR to provide power when modulating. Connect  
line voltage to Terminal LR only after removing power on terminals A and Z  
(otherwise actuator damage may result).  
6. Connect line voltage to terminal A to drive the actuator to the maximum (high fire  
purge) position.  
Once the maximum position is reached, terminal 11 (on switch I) will be energized  
to provide position feedback.  
7. Connect power to terminal ZL to drive the actuator to the minimum (low-fire)  
position. Once the minimum position is reached, terminal 23 (on switch III) will be  
energized to provide position feedback. Adjustment of switch III will determine the  
low-fire stop position. Switch III (low fire) must be set at a higher position than  
switch II (fully closed). Terminal ZL may be energized only after removing power  
from terminals A, Z, 13, and LR.  
8. Connect line voltage to terminal Z to drive the actuator to the fully closed/economy  
position (switch II).  
9. Connect the input control signal wires to the appropriate terminals. See Figure 9.  
CAUTION:  
Do not power terminals A and Z simultaneously. Actuator damage will  
occur.

Modulation Adjustment  
The blue trim potentiometers allow the adjustment of the minimum (zero) and  
maximum (span) positions.  
See Figures 10 and 12.  
The factory setting of the MIN trim potentiometer is rotated fully counter clockwise.  
The factory setting of the MAX trim potentiometer is rotated fully clockwise.  
Zero Adjustment  
Set the OPE/MAX/MIN slide switch to MIN. The blue MIN trim potentiometer can now  
be gently adjusted to the required minimum position. Return the OPE/MAX/MIN slide  
switch to OPE for operation.  
NOTE: Do not set switch cam I higher than:  
90° when using feedback potentiometers ASZxx.30  
135° when using feedback potentiometers ASZxx.33  
Span Adjustment  
Set the OPE/MAX/MIN slide switch to MAX. The blue MAX trim potentiometer can now  
be gently adjusted to the required maximum position. Return the OPE/MAX/MIN slide  
switch to OPE for operation.  
NOTE: The actual minimum and maximum  
modulating range is determined either  
by the setting of the MIN and MAX trim  
potentiometers or the setting of switch  
Example of limit switch I and III  
and trim potentiometer settings  
cam III (Minimum) and switch cam I  
(Maximum). The actuator can never  
modulate outside of the range set by  
switch cam I and III. If the MIN and MAX  
trim potentiometers are set outside the  
setting range of switch cams I and III,  
then the switch cam settings determine  
the modulating range. If a soft stop is  
desired, the modulating range can be  
defined by the trim potentiometers if the  
MIN and MAX trim potentiometers are  
set inside the setting range of switch  
cams I and III. See the example in  
Figure 13.

Features of  
SQM5x.xxxxxZx  
Actuators  
SQM5xx.xxxxxZx actuators contain the AGA56.9A… multi function circuit board. This  
circuit board provides the following features:  
Multiple Input Signals  
The AGA56.9A… circuit board accepts the following input signals:  
Line voltage  
Power to A drives the actuator open to the setting of switch cam I (Maximum).  
Power to ZL drives the actuator closed to the setting of switch cam III (Minimum).  
Power to Z drives the actuator closed to the setting of switch cam II (Economy).  
4 to 20 mA (Signal to Y3, common to M)  
0 to 135 Ω (Slide wire signal to Y0, potentiometer connected to M and U4)  
0 to 10 Vdc (Signal to Y1, common to M)  
0 to 20 mA (Signal to Y2, common to M)  
Multiple Output Signals  
The AGA56.9A… circuit board provides the following output signals:  
4 to 20 mA (Signal from U3, common to M)  
0 to 10Vdc (Signal from U1, common to M)  
0 to 20mA (Signal from U2, common to M)  
Double potentiometers ASZ22… provide additional output signals.

Electronic Linearization  
Function  
Butterfly valves have non-linear flow characteristics. Near the fully closed position, a  
small change in the valve’s position will produce a very large change in flow. Near the  
fully open position, a large position change will produce a relatively small change in flow.  
The linearization function is intended to minimize the initial steep flow curve  
characteristics of a typical butterfly valve. The linearization function is enabled when  
Jumper J1 is in position 1 (upper position). Consequently, the actuator will make smaller  
rotational movements when subjected to lower input signals and larger rotational  
movements when subjected to higher input signals.  
For example (based on a 90° modulating range), a change in input signal from 4 to 8 mA  
will cause a rotational movement of 11.25°. An equal change from 16 to 20 mA will cause  
a rotational movement of 45°. Thus, with the linearization function enabled, the change in  
flow is closely proportional to the change in input signal.  
The linearization function is disabled when Jumper J1 is in position 2 (lower position).  
When disabled, the rotational movement of the shaft is proportional to the input signal.  
Input Signal Override  
Parallel Operation  
Line voltage to terminal P will drive the actuator to a pre-set adjustable position,  
overriding all modulating input signals. Use the potentiometer marked POS to adjust the  
override position to any setting within the setting range of switch cams I and III.  
NOTE: The input signal override can also be used for the ignition position of burners if  
different from the low fire position.  
Set Jumper J2 in position 1 (upper position) to configure the actuator for parallel  
operation. Input signals Y0, Y1, Y2 or Y3 are directly shunted to output signals U1, U2  
and U3. All output signals are available regardless of which input signal is applied.  
Master/Slave Operation  
Split Ranging  
Set J2 in position 2 (lower position) to configure the actuator for master/slave operation.  
The output signals U1, U2 and U3 reflect actual shaft position.  
AGA56.9… circuit boards have a modulating signal shift feature which can be used for  
split ranging. If no signal is present on Y0, Y1, Y2 or Y3, the actuator will modulate  
through the 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, then the actuator will modulate through  
the full rotational range in response to a 4 to 12 mA signal applied at ZF. (Maximum  
signal can be easily achieved by bridging terminals U4 and Y0.) See Figure 16.  
NOTE: It is possible to configure the actuator for split range operation 12 to 4 mA and  
20 to 12 mA. Consult your authorized Siemens Building Technologies  
combustion products sales representative for details.

1. Disconnect the wires marked 21 and 12, and reverse.  
2. Adjust all switch cams to the desired settings (see Figure 6):  
For CCW rotation use the black cam drum scales and the single switch cam  
pointers.  
For CW rotation, use the red cam drum scales and the double switch cam pointers.  
NOTE: Press and hold the black cam drum release button to rotate the cam drum.  
This will give easy access to the switch cams and a better view of the cam  
drum scales.  
If no potentiometer ASZ… is installed, the reversing procedure is complete. If a  
potentiometer ASZ… is installed, complete Steps 3 through 9.

Potentiometer  
Removal  
9. Remove the white plastic actuator position-indicating dial by gently pulling while  
rotating in the clockwise direction. See Figure 6.  
10. Disconnect the blue, black and brown wire from the potentiometer terminal block. See  
Figure 17.  
11. Remove the silver potentiometer alignment screw.  
12. Loosen the black potentiometer cam attachment screw approximately one turn.  
13. Gently wedge a small screwdriver between the potentiometer and the gray plastic  
housing.  
14. Carefully twist the screwdriver until the potentiometer releases from the cam drum  
shaft. Remove the ASZ… potentiometer.  
Potentiometer  
Installation  
1. Install the new ASZ… potentiometer by gently sliding the bushing over the cam drum  
shaft.  
2. Align the potentiometer alignment screw hole with the hole in the gray plastic housing  
and install the potentiometer alignment screw. See Figures 17 and 17a.  
3. The actuator position indicating pointer, located near the actuator gear end of the cam  
drum, must point to the “0” mark on the actuator position scale. See Figure 6. The  
scale is located on the cam drum nearest to the actuator gear end. Press and hold  
the black cam drum release button while manually rotating the cam drum.  
4. If installing a potentiometer without gear, manually rotate the potentiometer pointer  
until the pointer is exactly in the “min” position. See Figure 17. Firmly tighten the  
black potentiometer cam attachment screw while manually holding the potentiometer  
pointer in alignment. Check the alignment again.  
5. If installing a gear model potentiometer, manually rotate the potentiometer gear until  
the white line next to the “0” or “1” mark on the potentiometer gear face is exactly in  
alignment with the potentiometer gear alignment pointer. See Figure 17a.  
For counterclockwise (ccw) operation the line beside the “1” mark must exactly align  
with potentiometer gear alignment pointer. For clockwise (cw) operation the line  
beside the “0” mark must exactly align with potentiometer gear alignment pointer.  
Firmly tighten the black potentiometer cam attachment screw while manually holding  
the potentiometer gear in alignment. Check the alignment again.  
6. Connect the bundled blue, black and brown potentiometer wires to the terminal block  
located on the ASZ… potentiometer board. See Potentiometer Installation and  
Figures 17 and 17a.  
7. Re-install the white actuator-indicating dial by gently pressing it onto the  
potentiometer cam attachment screw. Align scale position “0” on the actuator position  
indicating dial with the dial pointer by rotating the dial in the clockwise direction to  
avoid loosening the potentiometer gear attachment screw. See Figure 6.
