8. When using a Warner Electric tension control,
follow the connection diagram supplied with
the control.
If a Warner Electric TCS-210, -220, -310, or
320 control is used, add a 68 ohm resistor
across the sense circuit. Although the TCS
series controls are recommended, a MCS
control can be used with normal hook-up.
9. Your ATT brake is now ready for its static test.
Apply DC voltage to the coil through the
brake control. The armature should pull
against the friction material face.
10. Run the brake under its operating load.
11. Your ATT brake may not achieve its full torque
until after a short “break-in” period. To break
in the brake, cycle it on and off under full load
at operating speed a minimum of ten times in
quick succession.
Your ATT brake is now ready to run.
Wear Indication
Your ATT brake should be visually inspected on a
periodic basis to determine if the wearing surfaces
warrant replacement. The friction face and
armature should be replaced when the armature
reaches the wear indicator on the magnet shell. If
replacement is not made at this time, further use
will wear into the screw heads making removal and
replacement of the friction facing difficult.
The drawing below illustrates the area to be
inspected.
When the friction surfaces are worn to this point,
replace with the appropriate friction face
replacement kit. All of the components needed to
refurbish the wearing surfaces of your brake are
provided in the replacement kit.
