Monitor Torque
Window
Provides a torque window during the rundown phase of the fastening cycle into which
achieved torque must pass through. This window looks back from the Snug Torque of
the step over the angle interval defined. If achieved torque is outside the window the
fastening cycle is ended with the Shutoff Code of [T]. YES enables this monitor, NO
disables this monitor.
Upper Torque Defines the high torque limit for the window.
Lower Torque Defines the low torque limit for the window.
Upper Angle Defines the low angle limit for the window referenced from when the
Snug Torque value.
Lower Angle Defines the high angle limit for the window referenced from when the
Snug Torque value.
Monitor Torque
Rate
Provides Torque Rate Monitoring during the step between a Rate Threshold to final torque
of the step. AVERAGE will provide the average torque rate during the step. INSTANT will
provide the instantaneous rate at the step target. Only available during Torque Control
strategies. NO disables this monitoring. The shutoff code is RATE.
Rate Threshold Defines the torque at which this monitoring begins
High Rate
The maximum peak rate for an acceptable fastening cycle. If the
actual rate exceeds this limit the fastening cycle will be flagged as
NOK and the RED LED on the front panel and tool illuminates.
Low Rate
The minimum peak rate for an acceptable fastening cycle. If the actual
rate does not achieve this limit the fastening cycle will be flagged as
NOK and the YELLOW LED on the front panel and tool illuminates.
Deviation Limit
Correlation coefficient for least square fit (straight line) of the torque
rate curve. A higher number correlates to a straighter line. If any
point exceeds the Deviation Limit the fastening cycle will be flagged
as NOK and the RED and YELLOW LEDs on the front panel and tool
illuminates.
