Setting the filter pump status detection
N O T E
Setting is only necessary in the following circumstances:
► The installation height of the filter container differs from the system-specific requirements.
(→ Installation and connection)
► The admissible frictional resistances in the supply lines differ considerably from those
specified.(→ Technical data)
The filter pump status detection signals via the system message Er88 if the filter pump is operating
correctly. The system message Er88 is not triggered unless the status detection is activated for 10 minutes
continuously. This prevents brief fluctuations in the water level from triggering the system message Er88.
Check the setting according to the water level in the filter container and correct it if necessary to ensure
that the status detection signals correctly. In addition, the losses in the supply line due to the filter pump
must be at least 3.5 mbar (3.5 cm).
► The status detection can be deactivated if necessary. (→ E7: Pump status detection)
How to proceed:
S
1. Remove the container cover.
– The filter drum is stopped for safety reasons if the filter cover is lifted and Er11 is indicated in the
display of the control system.
2. Switch off the filter pump.
3. Switch off the mains voltage (ensure that the control system is isolated).
4. Measure the distance between the top edge of the container and the level of the water and determine
the necessary position of the holder according to the table.
5. If the determined position differs from the current position, correct it as required
– Undo and remove both screws of the holder. Push the holder into the correct position and fasten
with both screws.
6. Fit the container cover.
7. Switch on the control system and filter pumps and check the function of the status detection.
The status detection is correctly set when the float sinks with the filter pump switched on and the system
message Er88 is only triggered 10 minutes after the filter pump is switched off.
