8.3.2 Error Overload
The Error Overload signals a hydraulic overload during a dispensing process, i.e. the
maximum pressure is exceeded.

Description:
The FP4 D is properly connected to an external controller via the electrical interface
and connected to the power supply.
The FP4 D has been successfully controlled by the external control (PLC) immedi-
ately before the occurrence of error E2 and has (attempted) to perform a dispensing
operation.
When the maximum permissible pressure is reached during or after a donation, the
FP4 D sends a permanent output signal as low level (0 V) to PIN 4 for external control
(PLC).
The error E2 (overload) 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.
