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

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.

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.

Figure 13. Switch cam and Trim

Potentiometer Setting.

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 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.

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

Master/Slave Operation

Split Ranging

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.

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.

Service Guide

Reversing Rotational Direction

The AGA56.1A97 circuit board provides no output signals. Install an ASZ… potentiometer to obtain an actuator position output signal.

WARNING:

Disconnect the power supply to the actuator before performing any service functions.

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.
