SERIES 61 AND SERIES 62 MODUTROL IV™ MOTORS
CAUTION
Careless Installation Hazard.
Use of excessive force while adjusting cams
damages the motor.
To avoid damaging motor end switches, set cams by
moving only the screwdriver top.
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Never turn the motor shaft by hand or with a wrench.
Forcibly turning the motor shaft damages the gear train
and stroke limit contacts.

Select and install a shunt resistors to obtain the appropriate
feedback characteristic for your application. See the
Specifications section for details on feedback resistance
without a shunt resistor.
• Linear feedback provides linear indication of shaft position
with no shunt resistor.
• Slaving a Series 90 Motor requires full-stroke feedback
resistance of 142 ohms. Select and attach the proper shunt
resistor across terminals Y and G (see Table 5 and Fig. 11).

Auxiliary Switches
Adjustable cams actuate the auxiliary switches. These cams
can be set to actuate the switches at any angle within the
motor stroke. Select switch differential of 1° or 10°.
Motors with factory-added auxiliary switches are shipped in the
closed position (fully counterclockwise, as viewed from the
power end). Auxiliary cam default actuates the switches 30°
from fully open with a 1° differential. With the motor in the
closed (fully counterclockwise) position, the auxiliary switch
breaks contacts R-B. See Fig. 9 (or the auxiliary switch
Installation Instructions) for auxiliary switch wiring.
NOTE: Series 2 Motors are shipped with auxiliary switch
cams that permit acceptance of 220736A,B Internal
Auxiliary Switch Kits. Refer to Form no. 63-2228 for
220736A,B Installation Instructions.
