Example 1: If the pH value of channel 1 is so high that chlorine metering in channel 2 could become
dangerous, then the metering of channel 2 is stopped when the pH value of channel 1 is too high
and an alarm is triggered.
Example 2: The ORP value of channel 2 does not match the chlorine dioxide concentration of
channel 2 and vice versa. Metering of chlorine dioxide can stop in these cases.
