Reversing Actuators

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 to 20 mA, 0 to 135 , 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 , 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 . 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.

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.

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.

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”.

Actuator Mounting

SQM5… actuators can be mounted in any orientation using the four 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.

Figure 6. Component Identification on the Cam Drum Side of the SQM5… Actuator.

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.

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.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. 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.

Cam Drum Adjustment

See Figure 6.

Position Indicating Dial

Adjustment

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.

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

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.
