9.2 LED error messages
The 'EcoUp' diaphragm metering pump has a red alarm LED that either
flashes (in case of level warning) or lights up (in case of empty signal or a
fault).
If the alarm LED is lit, please first check your metering container to see if the fill
level is still above the empty detection level. If the alarm was not caused by an
empty signal from the container, there is a fault with the pump.

If the fault is still present after all checks have been completed, please send
the pump to the Customer Service team.
