Testing the Brake
m WARNING
Qualified trained personnel are required
to perform this test. Any problems found
during this test must be corrected by
qualified personnel before the machine
is operated, or serious injury such as
amputation could result.
IMPORTANT
Excessive heat from frequent stops at short
intervals can damage the motor and brake.
Allow the brake to cool for at least two
minutes each time the motor is started or
stopped before continuing the test.
1. Start the machine (1). Use the Start-Up
Procedure in the operation section of the
machine instruction manual (2). Wait
10 seconds for the machine to reach full
operating speed.
2. Note the stop time (3) of moving
and rotating parts. See the machine
instruction manual or manual addendum
for stop time and a method to check for
rotating parts. For example, the machine
in the photo to the right has a feed belt
that can be checked for stop time. Other
machines have different parts to check.
Push the stop button and note the
stop time. A brake in good condition and
properly adjusted will stop mechanical
parts within the specified time.
3. If the stop time exceeds the specified
stop time, adjust or repair the brake (4).
See the following pages for information
on adjusting and repairing the brake.
