not indicate an analysis result)
2. green:
the water quality is below the specified limit
3. red:
the limit has been exceeded - the relay REL

analysis active 1. yellow:
the LED lights continuously, thus indicating
that an analysis is in progress.

the LED will flash, signalling that the
analysis interval has expired - next
analysis start is delayed because input

simultaneously (see program switch S4
and S5 on page 34

the LED flashes rapidly, signalling that the
