Servicing Modular Tension Brake Friction
Surfaces Magnet Inspection
Each magnet is supplied with visual wear
indicators. When the magnet is worn to these
indicators, pad replacement is required. (Figure
16)
If the magnet is supplied with an electronic wear
indicator, a signal will be sent to the control to
indicate replacement is required.
Both the visual and electronic wear indicators
are preset to indicate replacement at 85 percent
wear out, allowing 15 percent more life for
planned maintenance.
A used armature should not be resurfaced
nor turned over to be used on the other side.

Rebuild Procedure
Note: When disconnecting and reconnecting
leads to the magnet, the input power must be
shut off to the control system.
Removal of the Armatures
If required, remove the armature assembly from
the shaft.
Remove the brackets and magnet carriers to
gain access to the armature(s). Remove the
armature face(s) with the armature in place, if
possible. If machine framework or components
prevent face(s) removal, the entire armature
assembly may have to be separated from the
brake hub and removed from the machine to
access the face(s).
