Point Level Input Menu
(only appears if a digital input option card is installed, and a level switch radio button is selected in
the digital input section of the Start Up page)
Input
Displays which digital inputs are defined as level inputs.
Drum
Type in the text box the name of the container the level sensor to the left is measuring.
Status
Displays whether the drum is currently “Empty” or “Not Empty.” Possible status messages for
point level switches are; Normal, Low Alarm or Circuit Board Failure. See section 8.1 for a
complete description of error messages.
Drum Empty when Contact is
Click on the radio button that describes how your level switch operates. If the switch is closed
when the drum is empty, select “closed”. If the switch is open when the drum is empty, select
“open”.
Click on the “Submit” button to save the changes.
6.13 Corrosion Input Menu
(only appears if a 4-20 mA option card is installed, and a Corrosion radio button is selected in the
4-20 mA input section of the Start Up page)
Input
Displays which 4-20 mA inputs are defined as corrosion inputs.
Corrosion Rate
This displays the current rate of corrosion at the sensor.
Raw mA
This displays the mA output of the corrosion transmitter, before it is converted into a corrosion
rate. This is helpful for troubleshooting.
Status
This displays whether the current corrosion rate is “Normal” or in “High Alarm”. Possible status
messages are; Normal (everything is OK), Sensor Error (the sensor signal is not valid), Over
Range (between 20 and 21 mA), Under Range (between 3.9 and 4.0 mA), High Alarm or Circuit
Board Failure. See section 8.1 for a complete description of error messages.
4 mA =
Type in the text box the corrosion rate at which the corrosion transmitter will send an output signal
of 4 mA. Normally this will be zero mils per year.
20 mA =
Type in the text box the corrosion rate at which the corrosion transmitter will send an output signal
of 20 mA.
