The output relay should be configured as a limit relay. Otherwise, an alarm will be raised when-
ever the output is activated.
The drawing below shows how the fuel pump is activated when the level reaches 20 % and stopped again
when the level has reached 80 %.

6.16.1 Fuel fill check
The fuel pump logic includes a fuel fill check function.
When the fuel pump is running, the fuel level must increase by at least the percentage value in menu 6557
fuel fill slope within the fuel fill check timer set in menu 6553. If the fuel level does not increase as the
slope defines within the adjusted delay time, then the fuel pump relay deactivates and a fuel fill alarm oc-
curs. The fuel fill alarm can be enabled/disabled in menu 6553.
