Honeywell Series 41, Series 81 Data Sheet

Series 41 and 81

Modutrol IV™ Motors

PRODUCT DATA

FEATURES

APPLICATION

•Replaces M445, M845 and M865 motors.

•Models rated for 60 lb.-in. torque.

•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 normally closed valves and dampers.

•All models have auxiliary switch cams.

The Series 41 and Series 81 Modutrol IV Motors are 2-position (lineand lowvoltage 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.

•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.

CAUTION

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.

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.

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.

CAUTION

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.
