11. Your ATT brake or clutch is now ready for
its static test. Apply DC voltage to the coil
through the control. The armature should
pull against the friction material face with an
audible “click”.
12. Run the brake or clutch under its operating
load.
13. Your ATT brake or clutch may not achieve
its full torque until after a short “break-in”
period. To break in, cycle it on and off under
full load at operating speed a minimum of
ten times in quick succession.
Your ATT brake or clutch is now ready to run.
Note: Your application may require brake to be
cycled longer due to load and RPM.
