17.4 Potentiometer for servomotor SQN 3..., Type ASZ...
Single potentiometer as wire or conductive model. The potentiometer ASZ... is used for electrical impulse
transmission of the position of the actuator axes.
The potentiometer ASZ 12... is attached to the drive axis of the actuator SQN 3... and used to transmit the
position as well as provide position feedback (position setting).
NOTICE:
Single potentiometer as wire model ASZ 12.703: 1000
, current carrying capacity 100mA.
Single potentiometer as conductive model ASZ 12.803: 1000
, current carrying capacity 0.1mA.
Also available as double potentiometer type ASZ 22...
CAUTION!
Comply with max. current capacity 100

17.5 Retrofitting the servomotor for potentiometer operation
The servomotor SQN 3... can be retrofitted with potentiometer ASZ...
Remove the cover after unscrewing the slot screw in the centre of the cover.
Remove the control panel.
Insert potentiometer into the shaft of the switching roller. Adjust and later fix the the adjustable bearing
bush with its slot screw.
Note the values for the starting torque of 4 nm +- 0,1 Nm.
See Fig. 17-4 "Potentiometer schematics"
pos. 2 and Fig. 16-5 "Layout for refitting with potentiometer ASZ...on SQN 7..." pos.1.
Fix the potentiometer to the servomotor housing with a slotted screw (9.5mm length).
Set the new control panel and then the switching roller to 90°. Attach the scale dial in such a way that
the value 90° is set opposite to the marking arrow on the servomotor housing.
The display dial will then be visible through the slot when replacing and fixing the lid.
Set the potentiometer in the following position:
Position 0° of servomotor = 0 W; position 90° of servomotor = 1000 W
