Installation

 

Cover Removal 

Use a Phillips screwdriver to loosen the two screws 
on the actuator cover corners. See Figure 1. 

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

Figure 2. 

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 

Actuator Mounting 

SQM5… actuators can be mounted in any 
orientation. Optional base mounting brackets are 
available. 
 
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 

SQM5…actuators are factory-wired with Switch I 
(maximum), Switch II (fully closed/economy position) 
and Switch III (minimum/low-fire). The individual 
switch cams I, II, and III are factory set to 90

°

, 0

°

 

and 10

°

, respectively. See Figures 3 and 4.

NOTE: 

The single switch cam pointers are used 

 

together with the black scales when 

 

configured for ccw operation. 

 

The double switch cam pointers are used 
together with the red scales when 
configured for 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. 

 

 

 

SQM5x.xxxRxA actuators without 
potentiometer must be adjusted only 
between 0° and 160°.  

 
 

If a potentiometer is installed, the 
adjustable range of the switches depends 
on the range of the potentiometer. 
 

 SQM5x.xxxRxA

3

 actuators have a 90° 

potentiometer and the switches must be 
adjusted between 0° and 90°. 

 
 SQM5x.xxxRxA

4

 actuators have a 135° 

potentiometer and the switches must be 
adjusted between 0° and 135°. 

Shaft Adjustment 

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 

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 3). 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. 
 

Position Indicating Dial Adjustment 

The actual position of the SQM5… actuator is 
indicated by the gray actuator position indicating 
pointer (see Figure 3). 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. 

 

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-inch NPSM  
conduit connectors. The use of flexible 14 gauge or 
smaller stranded wire is recommended. 

NOTE:

  SQM5… Actuators require a single-source, 

single-phase power supply.

Commissioning 

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 powered 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: 

 

Actuator damage will result if power is supplied 
to terminals A and Z simultaneously.

the cover end into the groove at the gear end of the 
actuator (See Figure 6).

 

2.  Press the cover into place and then press the 

screws inward and tighten (See Figure 7).
