RE-SETTING PROCEDURE
1. Shut down the machine drive.
2. Apply air pressure to the Torque Limiter.
3. Rotate Drive Flange Assembly by hand or in "jog"
mode until the balls are engaged in the detents.
INTERFACE DESIGN
The Torque Limiter interface consists of opposing balls and
detents that are not equally spaced and engage in one rota-
tional position. This feature provides exact timing or registry
of machine components connected on the drive and driven
side of the Torque Limiter. If an overload occurs, the torque
limiter interfaces separate to completely disconnect drive
components from driven components.
4. Restart the machine drive.
NOTE
Machine must come to a complete stop before
Torque Limiter can be reengaged. Torque Limiter
may run in excess of 200 o F [93°C] as measured
on the Air Chamber until Rotary Seal has worn in.
