Low salt detection

1 Water softening system
The PCB for the low salt indicator is attached with clips to the right
side of the water softening system (front side of appliance).
2 PCB with light barrier
1 Photodiode
2 Regeneration salt
The salt level is detected via a light barrier. If the regeneration salt
runs low, the line in the light barrier is freed and the electronics detect
"Add salt".
If the low salt indicator appears, there is still so much salt in the
appliance that some more regeneration processes may occur.
According to this principle it is not necessary to fill the salt dispenser
with water when switching on the appliance for the first time.
Filling with salt tablets is system-dependently not recognized.
