Dose flow deviation [%]
This sets the percentage by which the ‘Measured total flow’
may drop below the 'Calculated dose flow'. If the 'Measured
total flow' drops any lower, then the alarm message 'Dose
flow too low' will be generated.
Here you enter the percentage by which the 'Measured total
flow' may rise above the 'Calculated dose flow'. If the
'Measured total flow' rises any higher, then the alarm
message 'Dose flow too high' will be generated.
This alarm will be generated once the time set for 'Delay
dose flow alarm' has elapsed.

Minimum EC zone [mS/cm]
If the 'Measured EC' drops below the 'EC setpoint' by the
value in mS/cm set here, then the alarm message 'Control
EC too low’ will be generated.
This alarm will be generated once the time set for 'Delay EC
alarm' has elapsed.
Maximum EC zone [mS/cm]
If the 'Measured EC' rises above the 'EC setpoint' by the
value in mS/cm set here, then the alarm message 'Control
EC too high' will be generated.
This alarm will be generated once the time set for 'Delay EC
alarm' has elapsed.
Minimum pH zone
If the 'Measured pH' drops below the 'pH setpoint' minus the
value set here, then the alarm message 'Control pH too low’
will be generated.
This pH alarm is only generated during the disinfection
phase.
See also: "Cleaning quartz tubes / Safeguards" on page85.
The system will wait until the 'pH alarm delay' has elapsed
before generating the alarm.
