• Fixed torque throughout the entire voltage range.
• Integral spring return returns motor to normal position
when power is interrupted.
• Integral junction box provides NEMA 3 weather
protection.
• Motor and circuitry operate from 24 Vac. Models
available with factory installed transformer, or a field
added internal transformer.
• Quick-connect terminals are standard—screw terminal
adapter is available.
• Adapter bracket for matching shaft height of older
motors is available.
• Motors have field adjustable stroke (90° to 160°).
• Die-cast aluminum housing.
• Motors are designed for either normally open or
APPLICATION
The Series 41 and Series 81 Modutrol IV Motors are
2-position (line- and low- voltage control, respectively)
spring-return motors. They are used to operate dampers or
valves in applications where it is necessary or desirable to
have the controlled element return to the starting position in
the event of power failure or interruption.
normally closed valves and dampers.
• All models have auxiliary switch cams.
• Integral auxiliary switches are available factory
mounted, or can be field added.
• Motors can operate valve linkages from the power end
or auxiliary end shafts for normally closed or normally
open valve applications.
• All models have dual shafts (slotted and tapped on
both ends).
• Nominal timing standard of 30 seconds (90° stroke),
and 60 seconds (160° stroke). Other timings available.

INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect all power supplies before installation.
Motors with auxiliary switches can have more than one
disconnect.
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.
Location
Allow enough clearance for installing accessories and motor
servicing when selecting a location (see Fig. 2). If located
outdoors, use liquid-tight conduit connectors with the junction
box to provide NEMA 3 weather protection. If mounted
outdoors in a position other than upright, install a 4074ERU
Weatherproofing Kit and liquid-tight connectors to provide
NEMA 3 protection.
Motor Damage Hazard.
Deteriorating vapors and acid fumes can damage
metal parts.
Install motor in areas free of acid fumes and other
deteriorating vapors.
In excessive salt environments, mounting base and screws
should be zinc or cadmium plated, not stainless steel or
brass. Use the 220738A Adapter Bracket for mounting on
these surfaces.
