Name Description Raising condition Falling condition
Pset status
Pset selected
bits (0..7)
Echoes the binary "Pset select bit 0 to 7" input if the
corresponding Pset exists, echoes 0 if the Pset does not exist
or there is no Pset selected.
New Pset selected New Pset selected
Tightening
running (old
cycle declared)
This indicates that the fastening operation has actually started:
the tool is running and the torque is over the Pset start torque
threshold.
The signal switches off as soon as the fastening operation is
finished (all reports sent).
Torque reach the cycle
start threshold.
The fastening
operation is finished
(all reports sent)
Tightening
finished
Indicates that a Pset report is available. Result generation. New start (tool trigger
or external start) or
reset input
Tightening OK Indicates that the fastening operation (for a specific Tightening
Unit) ends correctly and that all controlled and monitored
tightening parameters are within tolerances.
Result generation. New start (tool trigger
or external start) or
reset input
Tightening NOK Indicates that the fastening operation (for a specific Tightening
Unit) has failed.
Result generation. New start (tool trigger
or external start) or
reset input
Spindle OK Indicates that the fastening operation (for a specific tool) ends
correctly and that all controlled and monitored tightening
parameters are within tolerances.
Result generation. New start (tool trigger
or external start) or
reset input
Spindle NOK Indicates that the fastening operation (for a specific tool has
failed.
Result generation. New start (tool trigger
or external start) or
reset input
Angle low Indicates a low angle reject.
The angle must meet or exceed this value for a correct Pset.
When the angle stays below this value, it becomes a "Low
angle reject" and this output is turned on.
Stays on until a new fastening operation starts.
Result generation. New start (tool trigger
or external start) or
reset input
Angle OK Indicates a correct angle.
The angle is inside the limits declared in the step.
Result generation. New start (tool trigger
or external start) or
reset input
Angle high Indicates a high angle reject.
The angle must stay below this value to be a correct Pset.
When the angle meets or exceeds this value, it becomes a
"High angle reject". The tool will stop when this limit is reached
and this output is turned on.
Stays on until a new fastening operation starts.
Result generation. New start (tool trigger
or external start) or
reset input
Torque low Indicates the peak torque low reject.
If the torque stays below the "Peak torque low limit" and
results in a “Reject” Pset. This can happen when a Pset is
prematurely finished, a thread strips out or when the Pset is
automatically finished due to other error conditions, such as
a High angle fault or when a Pset Time Monitor expires and
causes the Pset to be terminated.
Stays on until a new fastening operation starts.
Result generation. New start (tool trigger
or external start) or
reset input
Torque OK Indicates a correct torque.
Torque is in inside the limits declared in the step.
Result generation. New start (tool trigger
or external start) or
reset input
Torque high Indicates the peak torque high reject.
When the torque meets or exceeds this value, this output is
turned on and the results is NOK. If a Peak Torque High error
persists, it may be advisable to slow down the tool speed
or replace the tool with one of lesser capacity. A second
variable that can cause Peak Torque High errors is a badly
chattering joint. Chatter is the squawking noise you hear
on some fasteners at the end of the fastening operation.
Chatter is induced by slip-stick and actually causes the
fastener to momentarily stop rotating, then crack loose and
re-start turning. This condition can cause a Peak Torque High
condition. A potential solution for this is to view Psets, General
Tab, and set the frequency response slide bar to Better
Noise Immunity, Chattering Joint). This causes the software
to average many torque readings together to minimize the
possibility of using a single high frequency torque value that
could trigger a peak torque high fault.
Stays on as long as a new fastening operation starts.
Result generation. New start (tool trigger
or external start) or
reset input
