SERIES 90 MODUTROL IV™ MOTORS

63-2631

Fig. 8. Potentiometer location and stroke adjustment setup

for non-spring return Series 90 Motors

To set the stroke between 90° and 160° follow the procedure

below:

Turn the stroke potentiometer fully CW

, using a

1/8 in. straight-blade screwdriver to set 160° stroke.

Set the maximum position using an external 135 Ohm

potentiometer.

Turn the sensitivity potentiometer, so that the shaft

reaches the final position of selected stroke.

Turn the stroke potentiometer CCW

until the shaft

begins to move. Then turn potentiometer back slightly to

have the position correspond to the sensitivity potenti-

ometer.

Make sure the minimum position corresponds, as well.

Linearization Potentiometer

Series 90 motors use a linearization potentiometer. This

potentiometer should be adjusted only when Series 90 is used

with an interface module, which converts the control from

series 90 to series 70. If you use an interface module, set the

linearization potentiometer according to the switch on the
interface module. Turn the potentiometer fully CW

for

driving the motor CW, turn the potentiometer fully CCW

for driving the motor CCW. Table 6 summarizes the modules

and the positions of the linearization potentiometer.

Table 6. Position of Linearization Potentiometer

Adjustable timing for M9181D1024

The timing potentiometer (the second from the right, see
Fig. 8) sets the timing to 1minute, if turned fully CCW

, 2

minutes if turned to its middle point and 4 minutes if turned fully
CW .
