Minimum m

for start cleaning [m

]
This sets the amount of water (in cubic metres) that must have passed
through the quartz tubes since the last time that the quartz tubes were
cleaned, in order for the cleaning process to start.
If the amount of water is lower than the value set here, then the alarm
message 'Quantity disinfected too low' will be generated and the unit
will be paused.
If a manual start is performed, then the unit will not check whether
this minimum amount of water has passed through the quartz tubes.
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.
A pH alarm is only generated during the acid circulation phase. The
system will wait until the 'pH alarm delay' has elapsed before
generating the alarm.
If an alarm is generated, the unit will be paused.
Maximum pH zone
If the 'Measured pH' rises above the 'pH setpoint' plus the value set
here, then the alarm message 'Control pH too high' will be generated.
A pH alarm is only generated during the acid circulation phase. The
system will wait until the 'pH alarm delay' has elapsed before
generating the alarm.
If an alarm is generated, the unit will be paused.
Minimum flow [l/min]
If the flow rate drops below the value set here, then the alarm
message 'Flow too low’ will be generated. The unit will also be paused.
To disable minimum flow monitoring, set this value to 0.
Maximum flow [l/min]
If the flow rate rises above the value set here, then the alarm
message 'Flow too high' will be generated. The unit will also be
paused.
To disable maximum flow monitoring, set this value to 0.
