Description:
• If an error occurs in the FlexxPump 125, the FlexxPump 125 sends a low-level signal at
PIN 4 to the controller. This signal must be available uninterruptedly for at least 4 s before
the error message can be acknowledged.
• The 24-V signal 10sec (9.9 s ... 10.1 s) can then be sent to the FlexxPump 125.
• After the signal drops to 0 V, the error is cleared, the LCD shows CLr.
If an error occurred during execution of a control signal, this process is continued after the
error has been cleared.
