5.2.2 Setting the level detection device
Adjust the level detection device to the water level in the container to ensure the optimum opera-
tion of the filter system. A 10 mm open jaw spanner is required for this adjustment.
How to proceed:

R
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 pumps and check the water level.
– Ensure that the water level reaches the height of the maximum mark on the inside wall of
the container, at least above the Min. mark.
– Adjust the water level in the pond if necessary.
3. Switch off the mains voltage (ensure that the control system is isolated).
4. Loosen both screws of the level detection device so that it can be easily moved.
5. Fit the container cover.
6. Switch on the control system and filter pumps and start a cleaning cycle.
7. Isolate the control system and remove the container cover.
8. Move the level detection device until the marking on the housing coincides with the water
level.
9. Tighten the two screws of the level detection device.
10. Replace the container cover and switch on the control system.
T I P
• Perform the setting quickly following the cleaning cycle. The screen elements contin-
ually trap dirt particles. This causes the water level to drop in the container.
• Subsequently start a new cleaning cycle and check the setting. Check the setting if
necessary.
• Check the setting again when the desired water quality has been reached.
5.2.3 Setting the filter pump status detection
T I P
Setting is only necessary in the following circumstances:
• The installation height of the filter container differs from the system-specific require-
ments.
• The admissible frictional resistances in the supply lines differ considerably from those
specified.
The filter pump status detection signals via the system message
Er88
if the filter pumps are op-
erating correctly.
• If the filter pumps are switched on and running without malfunctions, the water level in the
drum filter drops and the float is suspended freely.
•
If the flow volume drops (e. g. malfunction on a filter pump), the water level rises and the
system message
Er88
is triggered.
– 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 neccessary to
ensure that the status detection sends the correct signal. In addition, the losses in the supply
lines due to the filter pumps must be at least 3.5 mbar (3.5 cm).
• The status detection can be deactivated if necessary. (→ Setting the filter pump status de-
