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

Technical Instructions Document No. 155-517P25 Rev. 1, July, 2000 Installation and Operation Instructions SQM5… actuators are generally 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. EA0564R1 EA0568R1 Shaft Installation Figure 3. Figure 2. 3. Each shaft is supplied with two washers and a “C” clip. See Figure 4.

Technical Instructions Document No. 155-517P25 Rev. 1, July, 2000 Switch Adjustment, continued NOTE: Shaft Adjustment 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. See Figure 6.
