7.2 Haptic test
The haptic test checks how the switch in this window changes its state, that is,
the "feeling" on actuation. The characteristic values required to do this can be
entered in the haptic test dialog box via the PME Assistant or INDUSTRY-
monitor. Any combination or all the characteristic values listed can be tested.
The check is NOK as soon as one of the activated characteristic values is not
OK. The individual characteristic values are clearly shown in the graphic
below.
For the haptic test, the curve must enter and exit the window at the sides and
the window must always be square. It is not possible for the curve to enter or
exit the window at the top or bottom.
TIP:
To secure the process, additional process windows can be set up to evaluate
the process curve in real time and so assist machine protection. If the switch
is defective, limit force switch off is implemented with a reaction time of
approx. 2 ms.
Further information can be found in the online help of the PME Assistant
and the MP85A process controller interface description.
