Messages Displayed for Equipment or Brake Monitor Problems

These messages tell you that something is wrong with the SmartPAC 2 resolver, input circuit,
or position sensor or with the way your press is running. Some fault messages indicate that
there is a problem related to the brake monitor. These messages may also indicate an internal
problem with SmartPAC 2 itself.
If you cannot correct the problem after reading the remedy, contact Wintriss Tech Support.
Whenever you need help, just remember that we have expert representatives available to help
you by phone. Never hesitate to call if you have trouble with SmartPAC 2.
After you have corrected the problem, press RESET. If the problem is corrected, you will be
able to run the press again. If not, you will get the same fault message.
"Loss of rotation detected"
Explanation: The resolver did not start rotating within the start time limit that is preset
in Initialization mode. Or the resolver could have stopped turning while
the press was running. SmartPAC 2 knows when the clutch/brake valve is
energized. If it sees that the valve is energized but the resolver is not
turning, this message appears. For an explanation, see "How the input
check circuit works" in Chapter 2.
One possible cause is that the resolver's drive belt may be loose or broken
so the resolver does not turn (or stops turning) even though the press
crankshaft is turning. Also you may have low air pressure to the clutch or
a bad clutch; so the crankshaft (and therefore the resolver) did not move
even though the clutch control valve has been activated. An internal
SmartPAC 2 problem could also have occurred, or the resolver could be
defective.
Remedy: Check the resolver and resolver drive. Check and repair the clutch. If these
solutions do not work, an internal problem may have occurred. Contact
Wintriss Tech Support.
