Switch Adjustment,
continued
NOTE: SQM5x.xxxxxAx actuators may be adjusted between 0° and 160°.
SQM5x.xxxxxx3 actuators have a 90° potentiometer and the switches must be
adjusted only between 0 and 90°. SQM5x.xxxxxx4 actuators 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 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.
Cam Drum Adjustment
See
Figure 6
.
The cam drum must be manually aligned by pressing and holding the black cam drum
release button. The cam drum must be rotated until the “0” mark on the cam drum
position scale (left scale on the cam drum) is aligned with the gray actuator position
indicating pointer.
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
To avoid electro-magnetic interference, the SQM5… actuators must be grounded.
The ground terminal is located to the right of the auto/manual switch.
Wiring connections
NOTE: SQM5… actuators require a single source, single phase power supply.
Wiring connections vary depending on which AGA56…. circuit board is installed.
AGA56.1… circuit boards.
See Figures 7 and 8
.
1. Connect line voltage to terminal L. Terminal L must be powered to enable manual
operation.
2. Connect neutral to the double terminal block with the two gray motor wires, located
on the left side of the gray switch housing.
3. Connect line voltage to terminal A to drive the actuator in the opening direction.
4. Connect line voltage to terminal Z to drive the actuator in the closing direction.
