Errors (Read Only)
The errors window will populate with messages which signify a problem with the
operation hardware inside the insertion turbine meter. Please contact ONICON
immediately if any error messages appear.
Alarms (Read Only)
When an alarm is present on this page, a message describing the problem will
appear, and the status indicator at the top of the page will say “ALARM” with an
orange background.
The following is a list of possible alarms, their causes, and what happens when
they’re present:
• Low Flow – The ow being measured by the turbine meter is outside the
2% of rate accuracy range of the meter (less than 0.4 ft/sec pipe velocity).
Low ow is a status alarm and the meter will continue to operate like
normal while it is present. If you believe more ow should be present,
remove and inspect the turbine for debris or damage. Or, if this is a
new installation, be sure the meter is installed at the correct depth and
orientation.
• Top Turbine Alarm –With the turbine rotation test enabled, the top turbine
is rotating at a speed outside the percent dierence allowed by the turbine
rotation test conguration. When this alarm is present, the relay output will
close if enabled to do so in the “Turbine Rotation Test” tab. Remove the
meter and inspect the top turbine for debris if this alarm is present.
• Bottom Turbine Alarm - With the turbine rotation test enabled, the bottom
turbine is rotating at a speed outside the percent dierence allowed by the
turbine rotation test conguration. When this alarm is present, the relay
output will close if enabled to do so in the “Turbine Rotation Test” tab.
Remove the meter and inspect the bottom turbine for debris if this alarm is
present.
• Turbine Average Alarm -With the turbine rotation test enabled, the average
turbine signal is measuring a speed outside the percent dierence allowed
by the turbine rotation test conguration. When this alarm is present, the
relay output will close if enabled to do so in the “Turbine Rotation Test” tab.
Contact ONICON if this alarm is present.
Warnings (Read Only)
Warnings will occur when the meter is operational, however, the output of the
meter is likely unreliable. Warnings will automatically clear once the cause of the
warning has been resolved.
• High Flow – This warning will appear when the ow rate being measured
by the meter has exceeded the full scale analog range programmed in the
“Flow Settings” tab. Increase the full-scale range or lower the ow to clear
this warning.
• Supply Voltage Low – The supply voltage to the meter is too low. The input
voltage should be 24±4 VAC or VDC.
