Description:
The FlexxPump 125 is properly connected to an external controller via the electrical
interface and connected to the power supply.
The FlexxPump 125 has been successfully controlled by the external control (PLC)
immediately before the occurrence of error E2 and has (attempted) to perform a
dispensing operation.
The Pulse-Control-Mode PUL is activated on the FlexxPump 125, E2 is displayed in
the LCD and the red LED lights up.
When the maximum permissible pressure is reached during or after a donation, the
FlexxPump 125 sends a permanent output signal as low level (0 V) to PIN 4 for exter-
nal control (PLC).
The error E2 (overload) must be acknowledged with the control signal 14 seconds
(chapter 8.2.3) after elimination of the cause(s).
The FlexxPump 125 does not process control signals until all errors have been
eliminated.
