level are named Bolt var. 01 , Bolt var. 02 , etc. The first 40 variables of each type are marked with a T , to
indicate that these are scaled according to the torque unit selection in the reporters.
It is also possible to select Not reported , which mean that no value will be reported for the check.
Checks that run in a zone, i.e. have Operate on set to Zone , can not use the Specialized variable for
reporting, only the Step var and Bolt var are avaliable.
Note: It is only possible to use the same variable once in each step. For example, with two Peak Torque
checks on the same step with channel selection Torque 1, only one can use the specialized variable Peak
T1, the other one must use one of the general variables (or not reported). Setup problems will detect any
errors and generate warnings if needed.
6.5.4.2 Check peak torque
Parameters: TH (Torque high), TL (Torque low),
Set null position (Store peak position to Null position register) (only available for Gauging)
Set peak position (Store peak position to Peak position register) (only available for
Gauging)
Function: The peak torque from check start to check stop is checked to be between the high limit TH
and the low limit TL .
Both limits are optional. Leaving them blank disables the check but the result value is still
calculated and reported.
If the check operates on step it starts at step start. It ends when the step ends, including
overshoot time. If the check operates on zone the check starts when the selected zone
starts and ends when the zone ends.
If
Set null position or Set peak position is set the peak position, that is the angle where
the peak torque was found, is stored in the corresponding position register. It is possible to
return to this position later with the step
POS - Run to Position (only available for Gauging).
This check requires that at least one sample is collected after the torque spike elimination
phase. If not, and at least one limit is specified, the steps status is set to
Fatal and the error
bit of the respective limit is set.
