5.6.9 Acknowledgement of a class 3 system error via the PLC interface
(1)
Input, (2) Output
A class 3 system error occurs in the tightening controller, i. e. the tightening controller is no longer ready-
to-operate (Rdy = "low"). The system error is acknowledged when the
ResF signal changes from "low"
to "high", i.e. NF = “high”, and the controller is ready again ( Rdy = "high").
5.6.10 PLC behavior with a class 1 system error
A class1 system error occurs in the tightening controller, i.e. the tightening controller is no longer ready
for operation (
Rdy = "low"). As an error of this error class cannot be acknowledged via the PLC interface,
the tightening controller does not react to the ResF signal changing from "low" to "high" and the timeout
of 1 s elapses without the system error being acknowledged.
A class 1 error can only be acknowledged by switching the system off and on or by resetting the
controller.
