509 - R Col Dist Limit
The collapse distance
used in the most recent
weld was less than the
lower reject limit you set.
Discard the part. If you
encounter numerous or
successive alarms with
good parts, you might
change your reject
collapse distance limits.
510
+R Weld Force
Limit
The actual Weld Force
exceeded the plus Reject
Weld Force limit.
Discard the part if you
encounter numerous or
successive alarms with
good parts. Consider
changing your Weld Force
settings.
512 -R Freq Limit
The system Bandwidth
Limit (SBL) function has
determined the frequency
has dropped too much
and is now close to the
series resonant point.
Verify integrity of stack.
Review application.
513 +R Freq Limit
The system Bandwidth
Limit (SBL) function has
determined the frequency
has risen too much and is
now close to the series
resonant point.
Verify integrity of stack.
Review application.
514 +R PMC Band Limit
The Power Match Curve
function has detected
points above the
acceptable curve.
Run additional cycles to
determine if this is a trend
or an anomaly. Examine
process and adjust
accordingly.
515 -R PMC Band Limit
The Power Match Curve
function has detected
points below the
acceptable curve.
Run additional cycles to
determine if this is a trend
or an anomaly. Examine
process and adjust
accordingly.
551 - S Energy Limit
The energy used in the
most recent weld was
less than the lower
suspect limit you set.
Manually inspect the part
for a good weld. If you
encounter numerous or
successive alarms with
good parts, you might
change your suspect
energy limits.
