8.3.3 Error Under- or Overvoltage
Error Under- or Overvoltage indicates that the FP4 D power supply is not within the
specified parameters.
U
24V
0V

PIN 4
>3s
Description:
The FP4 D is properly connected to an external controller via the electrical interface
and connected to the power supply.
If the supply voltage is too low, the FP4 D sends a permanent output signal as low
level (0 V) to PIN 4 for external control (PLC).
Check the supply voltage and compare it with the parameters given in the FP4 D
technical data.
Error E3 (undervoltage) must be acknowledged with the control signal 14 seconds
(chapter 8.2.5) after elimination of the cause(s).
The FP4 D does not process control signals until all errors have been eliminated.
