6.5.4.4 Check torque in time window
Parameters:
TH
(Torque high),
TL
(Torque low),
Start time
,
Stop time
Function:
Start time and Stop time are both measured from the start of the step and define a time
window. All torque values within this window are 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.
This check requires that at least one sample is collected after the torque spike elimination
phase and that time Stop time is reached. 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.

Result var.:
"Ti Win Hi T" (time window high torque) and "Ti Win Lo T" (time window low torque).
Alarms:
Step torque high in time window (THTIWIN) and step torque low in time window (TLTIWIN).
Trace
:
TH and TL are shown in trace as horizontal lines from Start time to Stop time. The lines are
only shown when Torque vs. Time is selected and Check limits are enabled in the trace
