SERIES 90 MODUTROL IV™ MOTORS

Table 5. Series 90 Modutrol Motor Timing and Torque Ratings.

				Rated Torque in lb-in. (N•m)b
Nominal Timinga in sec		Normal Running Torque			Breakaway Torquec
90°	160°	Spring Return	Non-Spring Return		Spring Return	Non-Spring Return
30	60	25 (2.8)	35	(4)	50 (5.7)	70 (8)
15d/30	30d/60	60 (6.8)	75	(8.5)	120 (13.6)	150 (17)
30	60	—	150 (17)		—	300 (34)
60	120	—	300 (34)		—	600 (68)

aTimings apply to all TRADELINE models. Some OEM models are available with non-standard timing/torque.

bThe torque rating for dual-ended shaft motors is the sum of the shaft torques (power-end torque plus auxiliary-end torque). c Breakaway torque is maximum torque available to overcome occasional large loads such as a seized damper or valve.

d Low timing is for M9184D1005 only.

NOTE: Some 150 lb-in. and 300 lb-in. torque adjustable stroke motors have timings that are twice that of their fixed stroke counterparts.

IMPORTANT

Never use a Modutrol Motor continuously at the Breakaway Torque rating.

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.

IMPORTANT

Always conduct a thorough checkout when installation is complete.

Location

Allow enough clearance for installing accessories and motor servicing when selecting a location (see Fig. 1). 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.

Mounting

CAUTION

Equipment Damage Hazard.

Can damage the motor beyond repair.

Always install motors with the crankshaft horizontal. Improper motor mounting can result in inadequate motor gear train lubrication.

Use the following guidelines for proper motor mounting:

•Always install motors with the crankshaft horizontal.

•Mounting flanges extending from motor housing base are drilled for 1/4 inch (6.4 mm) machine screws or bolts.

•Non-Spring Return Motors are shipped from the factory in the closed position (at the limit of counterclockwise rotation, as viewed from the power end of the motor).

•Spring Return Motors are shipped from the factory in their normal position:

—Normally closed models: shipped at limit of counterclockwise rotation, as viewed from the power end of the motor.

—Normally open models: shipped at limit of clockwise rotation, as viewed from the power end of the motor.

NOTE: Refer to Fig. 2 for graphical representation of full open and full closed.
