Siemens Building Technologies, Inc.

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

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.
