Description

Features

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.

• Modulating accuracy of 250 repositions through 90°

• Two limit switches, plus up to four internal auxiliary switches

• Fully closed “economy position” switch

• Drive shaft and cam drum disengagement clutches

• Auto/manual switch, manual control forward/reverse toggle switch

• UL, CSA approved 24 and 110 Vac versions

• CE approved 220 Vac versions

• Field reversible clockwise (cw) or counterclockwise (ccw) operation

• Various torque ratings and running times available

• Selection of field exchangeable single-ended and dual-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 ignition and low fire. In dual fuel applications, additional switches can be used to create separate high fire, low fire and ignition 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 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.

Installation and Operation Instructions

SQM5… actuators are sometimes shipped without the shaft installed. To install the selected shaft:

1. Loosen the two screws on the actuator cover corners. See Figure 2.

2. Lift the screws and raise the cover. See Figure 3.

7. Line up the “shaft key” with the key slot on the “gear end” of the actuator and slide the shaft until the “insert end” is completely through the brass bushing.

8. Place the second washer onto the “insert end” of the shaft. Using spreading pliers, install the “C” clip.

Rotational Direction Verification

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.

To field reverse the direction of rotation, see Service Guide, “Reversing Rotational Direction”.

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

See Figure 6.

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.

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.

SQM5… Reversing Actuators Technical Instructions Document No. 155-517P25 July 9, 2007

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

See Figure 6. Position Indicating Dial

Adjustment

Wiring

Electrical Connection

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.

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.

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.

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

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.

Siemens Building Technologies, Inc. Page 9

Technical Instructions SQM5… Reversing Actuators Document No. 155-517P25 July 9, 2007

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.

Manual Operation

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.
