Brake Monitor Brake Warning

When the stopping time is within 10 milliseconds of the stop time limit set in SmartPAC, the
"Brake Warning" LED on the front of SmartPAC illuminates. This means that the stopping
time of the press is getting extremely close to the safety limit set.
To clear this message, you need to power down and up both WPC and SmartPAC. Keep in
mind, though, that the message will keep reappearing as long as the stop time is within 10 ms
of the preset limit. In order to remedy the situation, the first thing to consider is that your
brake may be defective and/or wearing, and needs immediate attention from your
maintenance personnel. Or if that is not the problem, it could also mean that your stopping
time limit is not great enough to account for normal wear.
You should have your maintenance crew immediately investigate the condition of the brake to
ensure that it is not wearing and/or defective before you adjust the stop time limit.

Brake Monitor - Stop Time Exceeded*

DANGER
!
INCORRECT SAFETY DISTANCE DUE TO INCORRECT STOP TIME
• Perform a 90 ° Stop Test any time you change the stop time limit. (See "Performing the 90 °
Stop Test," page 346.)
• Recalculate the safety distance based on the new stop time limit and adjust or reinstall
safeguarding devices according to the new safety distance.
Failure to comply with these instructions will result in death or serious injury.
When the Stop Time Limit has been exceeded, a message appears on SmartPAC's LCD
display. This means that the actual stopping time of the press has completely exceeded
whatever limit was set at SmartPAC, and therefore the press can not be used until the brake
has been repaired. It indicates a potentially dangerous safety problem which must be
corrected immediately.
