Malfunction of the condensate drain
Malfunctions or failure of the drain are indicated by
red LED, flashing at long intervals
red LED, flashing at short intervals
red LED, permanently only (ED3007 – ED3100)
If the condensate drain does not work properly, it is automatically cleaned. During
cleaning, the red LED flashes slowly, indicating that the program tries to remove
any dirt or clogging with compressed air. After successful cleaning, the drain is
emptied and is then automatically reset to normal operation.
If cleaning is not succcessful, the drain is switched to the emergency program,
which is indicated by the red LED flashing at short intervals (alarm).
If the red LED is permanently on, there is a system error. The condensate drain
is defective and must be replaced.
Note:
Too fast influx of condensate can result in an error message by the
magnetic level sensor due to inertia. To remedy this error, please
disconnect the drain from the voltage supply and re-initialise. The
alarm reset is not functional in this case.
