Setting Description
Record pause
(puse x2 =
delaytime This value indicates the intervals for recording the measured values in the log file. 1 value
corresponds to 2 seconds.
Max. limit
conductivity
[μS] This value indicates the conductivity limit; if this limit is exceeded a warning is generated.
Accuracy TOC
value This value indicates the number of decimal places used to display the TOC value.
Underpressure
limit [bar] This value is required for the pressure sensor option. It indicates the input pressure at the
which an error should be displayed.
Underpressure
restart [bar] This value is required for the pressure sensor option. It indicates the pressure at which the
measurement should be restarted after the vacuum is switched off.
The following parameters can be set in the Service 2 tab:
Setting Description
Use analog
output [ON /
OFF] The analog output can be switched on or off here.
4
Channels(analo
g output) If the system features the Interval option and 4 analog outputs, the analog outputs for TOC 2
and TOC 3 can be activated here for the additional connection.
0-20 mA
(analog output) If the system features the 0-20 mA option, this must be configured here. Otherwise incorrect
analog signals may result when scaling the TOC values. Information on the system features is
provided in the final test report.
Idle analog
output value
(only with 0-20
mA option) With the 0-20 mA option, the system can adopt any value if no measurement takes place.
The recommended value is 3.7 mA according to Namur NE43.
Hold the last
analog output
value If values are measured in interval mode, this option can be used to specify that the analog
output signals should always remain at the last measured value when the measuring inputs
change, even if no measurement is currently active.
The following parameters can be set in the Service 3 tab:
Setting Description
UV-Limit This value indicates the maximum period of time before a warning is generated if the
operating time of the UV lamp exceeds this limit.
Pump limit This value indicates the maximum period of time before a warning is generated if the
operating time of the pump hose exceeds this limit.
Valves This value indicates the number of valves the analyzer is fitted with. This value must be set
correctly here. Otherwise, malfunctions may occur when selecting the inputs in the
calibration and interval mode.
Universal digital
output If the analyzer is fitted with a universal digital output, this option can be used to configure
the system events that can cause the output to switch.
Fault - The output closes during measurement and opens during standby or in the event of
an error
Limit - The output changes if the limit value for TOC or conductivity is exceeded
Fault+limit - The output closes during measurement and opens during standby, in the event
of an error or if the TOC or conductivity limit value is exceeded.
Automatic
report At the end of the day (midnight), generates an automatic printout on the printer that is
installed in the system as a standard printer.
