Page | 54
COURSE OF ACTION FOR ERRORS
Read the error messages on the circuit board. We have put together solution guidelines
for the individual error messages.
Operating states which may be indicated when power is being supplied to the RSC
controller. The switch on the transformer for the 230 V mains supply and the LED for
the 24 V must be illuminated for this purpose.
Caution! - emergency mode: The system can be moved manually in emergency mode;
i.e. the programmed end positions are ignored and it must be stopped manually, as the
system may otherwise be damaged.
END POSITIONS DO NOT STOP AT THE RIGHT POSITION
Error:
Cover does not stop at the correct end point when closing (‘ZU’); parts of the swimming
pool are not covered.
Troubleshooting:
The end position closed (‘ZU’) likely needs to be readjusted.
Caution! If you are using PVC roller shutters in particular, make sure that the rods are
lying flat on the water at the rear in the closed state. If this is not the case, the profiles
will quickly become deformed due to being exposed to the sun.
Error:
Cover does not stop at the correct end point when opening (‘AUF’);
parts of the cover remain on the surface of the water.
Troubleshooting:
The end position (closed ‘ZU’ and opened ‘AUF’) need to be readjusted.
Caution! If you are using PVC roller shutters in particular, make sure that the rods are
lying flat on the water at the rear in the closed state. If this is not the case, the profiles
will quickly become deformed due to being exposed to the sun.
