Ensor Menu - P H Input - Walchem WebMaster ONE Instruction Manual

Temperature Units
Click on the radio button to select units of measure of either Fahrenheit or Celsius.
Uncalibrated Temperature
Displays the temperature reading before correcting with calibration constants. This is helpful for
troubleshooting.
This menu will not appear if no temperature sensor is detected at power-up.
High Alarm
In the text box, type the maximum temperature that you would reasonably expect to see for the
sample. This is helpful to detect a faulty or poorly calibrated temperature sensor.
This menu will not appear if no temperature sensor is detected at power-up.
Low Alarm
In the text box, type the minimum temperature that you would reasonably expect to see for the
sample. This is helpful to detect a faulty or poorly calibrated temperature sensor.
This menu will not appear if no temperature sensor is detected at power-up.
Click on the "Submit" button to save the changes.
6.5 Sensor Menu - pH Input
Select the option or type in the values that you want for each of the sections on the page. When
you click on the "Submit" button at the bottom of the page, your changes will take effect. If you
move to another page without clicking "Submit" first, your changes will be lost!
Certain menu sections will only be visible if you have selected certain options in the start up menu.
Type of Sensor
Click the pull-down to select the type of sensor that you have installed. The rest of this section
assumes that you have selected pH.
Custom Name
You can rename the input by typing a custom name in the text box provided. This name will
appear as the link to the input page, on the System Summary report, as a choice for relay input
assignments, on data logs, and in alarm messages.
Backup Sensor Mode
The redundant sensor algorithm will allow the user to define a primary sensor to use for control
and a backup sensor. If the primary sensor goes invalid, the backup sensor will automatically take
over control, and the sensor error alarm will activate. If the sensors don't match each other within
user-defined limits but both are valid readings, control will stop and a Sensor Deviated alarm will
activate. If the backup sensor goes invalid while the primary sensor is OK, control continues but
the sensor error alarm will activate. If both sensors are invalid, control stops and the sensor error
alarms activate.
To select this sensor as the backup sensor, click the Enable radio button, then click on the Submit
button at the bottom of the page. The page will reload showing the status of the sensor as Backup,
and offer additional menus:
