MICRO/2000® AND DEOX/2000® MODULE
The menus are easy to use, displayed in plain text and are selected using
softkeys.
3.1.1 Overall function
Possible measured values:
• Free chlorine*, total chlorine*, potassium permanganate*, chlorine
dioxide* ozone* (MICRO/2000® 3-electrode cell)
• Total chlorine*, sulphur dioxide* (DEOX/2000® 3-electrode cells)
* These measurements are automatically temperature-compensated.
The graphic display shows the measured data, limit values and setpoints
as numeric values, diagrams or a trend line.
3.1.2 MICRO/2000® and DEOX/2000® flow block assembly
These flow block assemblies guarantee a stable measurement signal with:
• Robust sensors
• Constant flow rate with the aid of the flow control valve
• Hydrodynamic grit cleaning of the Depolox® 5, MICRO/2000®
and DEOX/2000® flow block electrodes
• Optimum flow around all sensors
3.2 Measurement Inputs
In principle, the following sensor measuring module types or retrofit kits
can be installed at the module slot. The sensor measuring modules are
only supported in applications 1 and 2:
DES - for MICRO/2000® analyser with PT1000
DES - for DEOX/2000® analyser with PT1000
When the device is switched on, the menus are initialized according to
the installed sensor module. If the sensor modules are changed at a later
date, the user menus are automatically initialized when the device is
switched on. If no sensor measuring module is installed when the unit
Version 1, the message "No measurement available" appears.
The sensor measuring module should be considered as the main
measurement, and control functions such as ratio control, single feedback
closed loop, and combi-control are supported depending on the Process
Control option. No controller output is available for application 1.
