Description
Default
setup
P224
PVT min limit
This value is evaluated against the monitor interval peak value at the end of
the interval. If the torque value falls below this limit, an alarm is generated.
If P109 Monitor end time from is set to Cycle start, then range is from P115
Cycle complete value to P225 PVT max limit.
If P109 Monitor end time from is set to Rundown complete, then range is
from 0 to P225 PVT max limit.
P115 Cycle
complete
P225
PVT max limit
This parameter is monitored in real time during the monitor interval and if
exceeded, an alarm is generated.
P116
Rundown
complete
P230
PVT comp
When this option is set to “Yes” a prevailing torque PVT compensate is
(measured at the interval of 20 samples preceding start of P231 PVT comp
point) used as reference for the torque during the actual tightening cycle.
All torque values; i.e. P113 Final target, P111 First target and
P114 Final tq max are compensated (subtracted) from the
prevailing value. Also, the results are compensated.
No
P231
PVT comp point
The value can be set between 0 and 9999 degrees.
10 deg
P240
Tool tightening
direction
CW/CCW
Select tool rotation direction. “CW” for right hand threaded screws and
“CCW” for left hand threaded screws. To be able to start in the decided
direction, turn the tool direction ring to its correct position.
This parameter has no effect when running an Open end tool
(tube nut tool).
CW
P241
Soft stop
Yes/No
The PF will ramp down the torque when target is reached. The “Yes” option
is recommended.
Yes
P242
Alarm on rehit
Yes/No
If selected, Power Focus will detect rehits (event code E112 Rehit). The red
tool LED will be lit when a rehit is detected. The criteria for a rehit are a
short or a non-existent second stage in combination with a slow speed in the
first stage.
No
P243
Alarm on tq < target
Yes/No
Decides if the tightening should be approved if the final torque is lower than
the P113 Final target but above P112 Final torque min.
No
P244
Alarm on lost
trigger
Yes/No
Power Focus will detect if the tool trigger was released before the P113 Final
target was reached.
No
P245
DS torque tuning
factor
Only used if “DS con” is chosen as a P100 Control strategy. It compensates
for the error that DS measurement induces. The value can be set between 80
and 220 percent. For information how to adjust the DS torque-tuning factor,
see section DS con.
100%
P246
Alarm on end time
shutoff
Yes/No
If end time times out before P113 Final target was reached then an event code
will be displayed.
No
