Description:
The FP4 D is properly connected to an external controller via the electrical interface
and connected to the power supply.
There is an error at the FP4 D.
The FP4 D sends a permanent output signal (low level) to PIN 4, which indicates an
error to the external controller (PLC). This output signal must be permanently and conti-
nuously present for >3 seconds.
The control signal 14 seconds with a signal length of 14 (13.9 ... 14.1) seconds high
level can be sent from the external control (PLC) to the FP4 D. The control signal is
sent to the FP4 D by the external control (PLC).
At the end of the control signal, the integrated microelectronics of the FP4 D will auto-
matically check itself:
+If this internal check is successful, the output signal at the FP4 D changes from a
low level to a high level; the error is thus acknowledged and the FP4 D is ready for
operation again.
- If this internal check is not successful, the FP4 D continues to send a low level out-
put signal. The error is still present. For further measures in this case: Chap. 8.3.4.
A possible next control signal can be sent from the external controller (PLC) at the
earliest >3 seconds after the end of the error-free and successful motor run. In the
meantime, the FP4 D does not process any control signals.
Regardless of the principle of remote acknowledgement of an error, it is essential to
identify and eliminate the cause when an error message is present.
