Description:
The FlexxPump 250/400 DLS 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 FlexxPump 250/400 DLS 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
FlexxPump 250/400 DLS 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 FlexxPump 250/400 DLS does not process control signals until all errors have
been eliminated.
