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 4-20 mA, 0-135 Ω, 0-10 Vdc, 0-20 mA, position
proportional and floating control. The available output signals include 4-20 mA,
0-135 Ω, 0-10 Vdc, 0-20 mA, and 0-1000 Ω. SQM5… actuators are available with up to
eight internal, easily accessible and adjustable auxiliary 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 to 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 provide installation flexibility and allow for the simple replacement of
most competitive actuators.
Features •Modulating accuracy of 250 repositions through 90°
•Two limit switches, plus up to six internal auxiliary switches
•Full closed “economy position” switch
•Drive shaft and cam drum disengagement clutches
•Auto/manual switch, manual control forward/reverse toggle switch
•UL, CSA and CE approved 24, 110 and 220 Vac versions
•Field reversible clockwise (cw) or counterclockwise (ccw) operation
•Various torque ratings and running times available
•Selection of field exchangeable one and two ended shafts
•Mounting brackets to replace competitive actuators

Application SQM5… actuators are uniquely suited for both industrial and commercial applications.
The high level of accuracy permits precise modulating control of industrial process and
process heating applications, often significantly enhancing performance and product
quality.
In commercial and industrial burner applications requiring high turndown and reliable
ignition, the auxiliary switches can be applied to create separate positions for burner
light off and low fire. In dual fuel applications, additional switches can be used to create
separate high fire, low fire and light off positions for each fuel. The “economy position”
switch is used to drive the actuator to the full closed position when the burner is off.
In all applications, commissioning is simplified. Shaft and switch cam drum
disengagement clutches allow for the quick manual alignment of the actuator shaft and
switch cams. The forward/reverse toggle switch in combination with the auto/manual
selector switch provides direct manual control.

8. Place the second washer onto the “insert end” of the shaft. Using spreading pliers,
install the “C” clip.
Rotational Direction
Verification
Most SQM5… actuators are factory configured for counterclockwise (ccw), minimum to
maximum rotation when facing the gear end of the actuator, or clockwise (cw) rotation
when facing the other end of the actuator. SQM5.xxxxxxxR model numbers, ending with
R are factory configured for clockwise (cw) operation. 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 - Product Numbers for Accessories. 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
See Figure 6.
All SQM5…actuators are factory wired with Switch I (maximum), Switch II (full closed
“economy position”) and Switch III (minimum). The individual switch cams I, II, and III
are factory set to 90°, 0°and 30°respectively.
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: SQM5x.xxxxxAx actuators may be adjusted between 0°and 160°.
SQM5x.xxxxxx3actuators have a 90°potentiometer and the switches must be
adjusted only between 0 and 90°. SQM5x.xxxxxx4actuators have a 135°
potentiometer and the switches must be adjusted only between 0 and 135°.
Shaft Adjustment
See Figure 6.
The actuator shaft can be disengaged by pressing the silver shaft release button located
to the right of the auto/manual switch. The shaft can be manually rotated when the
button is pressed. Once pressed, the button can be locked by pushing it slightly
upwards. After the shaft has been manually aligned, re-engage the shaft by pushing the
shaft release button downwards.
Cam Drum Adjustment
See Figure 6.
The cam drum must be manually aligned by pressing and holding the black cam drum
release button. The cam drum must be rotated until the “0” mark on the cam drum
position scale (left scale on the cam drum) is aligned with the gray actuator position
indicating pointer.
Wiring
Electrical Connection 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.
Grounding
To avoid electro-magnetic interference, the SQM5… actuators must be grounded.
The ground terminal is located to the right of the auto/manual switch.
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.
See Figures 7 and 8.1. Connect line voltage to terminal L. Terminal L must be powered to enable manual
operation.
2. Connect neutral to the double terminal block with the two gray motor wires, located
on the left side of the gray switch housing.
3. Connect line voltage to terminal A to drive the actuator in the opening direction.
4. Connect line voltage to terminal Z to drive the actuator in the closing direction.

4. For applications where terminals Z, ZL, A and 13 are not used, bridge terminal LR
and L. If any terminals Z, ZL, A or 13 are used, terminal LR must not be bridged with
terminal L. In addition, terminal LR must never be powered simultaneously with any
terminals Z, ZL, A or 13. However, terminal LR must be powered once Z, ZL, A and
13 are no longer powered and modulating operation is required (refer to application
guide for typical installation examples).
5. Connect the input control signal wires to the appropriate terminals.
