• Periodic inspections should be performed. Failure to perform proper maintenance

can result in premature product failure and personal injury.

• All electrical work should be performed by qualified personnel and compliant with

local and national electrical codes.

• Read and follow all instructions carefully.
• Disconnect and lock-out power before installation and maintenance.

Working on or near energized equipment can result in severe injury or death.

• Do not operate equipment without guards in place. Exposed equipment can

result in severe injury or death.

1. GENERAL

Before assembly, the pressure plates, facings and center member (sprocket, sheave, plate, etc.) should be free of oil, grease, dirt

and rust. The center member should have a 125 micro-inch finish in the bore and a 63 micro-inch finish on the area where the friction

facings rub in order to obtain maximum rated capacity and optimum life from the Torque Limiter.

2. ASSEMBLY

Refer to the appropriate sketch (see below) and assemble on the torque limiter hub the following: (A) Friction facing (B) Bushing

(C) Center member (not shown) (D) Friction facing (E) Pressure plate (F) Spring(s) (G) Pilot plate (500A and 700A models only) (H)

Lockwasher (250A and 350A models only) (J) Adjusting nut.

4. TORQUE SETTING

(A) For the 250A and 350A models: To adjust the Torque

Limiter to carry the required torque, tighten the ad-

justing nut an appropriate amount.

Do not

completely

flatten the disk spring. Check setting per step 5.

3. RUNNING-IN

Torque Limiters should be run-in for the most consistent re-

sults. To run-in, adjust the Torque Limiter to 70-80% of the

maximum single spring capacity and slip the center member

approximately 60 RPM for approximately 4 minutes. (See steps

4 and 5 for setting and checking instructions.)
