Dead Band
The dead band prevents the flow total from accumulating when the flowmeter transmitter output is
just slightly above 4 mA. For example, entering a dead band of 0.1 mA means that any transmitter
signal below 4.1 mA will be recorded as a flow rate of 0.
20 mA =
Type the flow rate at which the water meter will send a 20 mA signal into the text box. This will
generally be at the maximum rated flow rate of the meter.
Units
Type the units of measure for the flow rate into the text box.
Rate High-High Alarm Limit
Type in the text box the process value above which you a want a high-high alarm to occur.
Rate High Alarm Limit
Type in the text box the process value above which you a want a high alarm to occur.
Rate Low Alarm Limit
Type in the text box the process value below which you want a low alarm to occur.
Low-Low Alarm Limit
Type in the text box the process value below which you want a low-low alarm to occur.
Rate Alarm Dead Band
Type in the text box the dead band to be used for each alarm set point.
Damping
Damping is applied to the input by taking a running average of the readings of the input signal
over the time frame specified by the damping setting (0-60 seconds)
.
The averaged reading is
displayed and used for control. Type in the text box the desired time frame.
6.10 Generic (4-20 mA) Input Menu
(only appears if a 4-20 mA option card is installed, and a Generic pull-down is selected in the 4-20
mA input section of the Start Up page)
Input
Displays which 4-20 mA inputs have been selected as “Generic” in the 4-20 mA input section of
the Start Up page.
Name
Type in the text box a name to describe the device connected to that 4-20 mA input (for example
“Pressure”).
