Description:
The FlexxPump 250/400 DLS is properly connected to an external controller via the
electrical interface and connected to the power supply.
The FlexxPump 250/400 DLS has been successfully controlled by the external control
(PLC) immediately 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
FlexxPump 250/400 DLS 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 FlexxPump 250/400 DLS does not process control signals until all errors have
been eliminated.
