OPERATION
Note! – In “Normal Operation” the hinge
cover is to remain tightly screwed closed. Under no
circumstance is it necessary for the operator to open
the enclosure.
Run Mode
The RUN mode is the normal operating mode of the analyzer and is entered upon power-up. When
the Run mode is entered the analyzer will determine what types of sensors are attached to each channel.
The supplied sensors have been calibrated at the factory. The display is continuously updated with the
current measurement values. Also, the analog output and the relays are updated according to the current
conditions and their programmed functions. In the event of an error or alarm condition the display will
indicate the problem in plain English text.
Sensor information for the Model 10 D.O. sensor is stored in non-volatile memory of the sensor.
Sensor information for the Model 15/15L TSS sensor is stored in non-volatile memory of the analyzer. If a
Model 15/15L is connected to the analyzer and the sensor information does not match the information
stored in the analyzer, the analyzer will display a configuration message. The configuration message for
the Model 15/15L TSS sensor is “**Zero sensor**”. These messages will appear whenever the sensor is
changed.
While in the RUN Mode, the time to next scheduled clean cycle can be viewed by pressing and
holding either arrow key. A clean cycle can be demanded by pressing the ENTER key while in the RUN
Mode, see the section on Demand Clean.
