the terminal). When open: Switch or terminal
contact faulty
2.
The total of the flow capacities of the dosing lines
is higher than the filling performance of the
GRANUDOS. Increase the chlorine dosing
performance setting at the GRANUDOS

Level max. ALARM:
Buffer tank Level max. alarm
The upper control switch
L-max. that stops the filling
has not been triggered.
The GRANUDOS switches
