occur if procedures are not
followed as specified.

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

actuators have a 90°

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

SQM5x.xxxRxA

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

Set the AUTO/MAN switch in the MAN position.

Connect ground to the screw located below the
shaft release button.

Connect neutral to the double terminal block,
located on the left side of the gray switch housing.

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.

6. Use feedback potentiometer ASZ… for Position

Proportioning Control. This potentiometer is located
at the end of the cam drum.

For information on potentiometer installation, see

Technical Instructions

155-517P25.

Cover Installation

1. Lift the two screws on the cover corners and slide

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).
