Description:
The FlexxPump 125 is properly connected to an external controller via the electrical
interface and connected to the power supply.
The Pulse-Control-Mode PUL is activated on the FlexxPump 125 and PUL is display-
ed on the LCD.
There is an error E2 ... E4 at the FlexxPump 125.
The FlexxPump 125 sends a permanent output signal (low level) to PIN 4, which indi-
cates an error to the external controller (PLC). This output signal must be permanently
and continuously present for >3 seconds.
The control signal 14 seconds with a signal length of 14 (13.9 ... 14.1) seconds high
level can be sent from the external control (PLC) to the FlexxPump 125. The control
signal is sent to the FlexxPump 125 by the external control (PLC).
At the end of the control signal, the integrated microelectronics of the FlexxPump 125
will automatically check itself:
+If this internal check is successful, the output signal at the FlexxPump 125 chan-
ges from a low level to a high level; error E2 or E3 is thus acknowledged and the
FlexxPump 125 is ready for operation again. CLR is briey displayed in the LCD,
then PUL again.
- If this internal check is not successful, the FlexxPump 125 continues to send a low
level output signal. The error (E4) is still present. The error is still displayed in the
LCD, the red LED continues to ash permanently. For further measures in this case:
Chap. 8.3.5.
A possible next control signal can be sent from the external controller (PLC) at the
earliest >3 seconds after the end of the error-free and successful motor run. In the
meantime, the FlexxPump 125 does not process any control signals.
Regardless of the principle of remote acknowledgement of an error, it is essential to
identify and eliminate the cause when an error message is present.
