4.4 ERROR HANDLING
The meter can detect errors in either the test or the measurement modes. When in the measurement
mode, a blinking vertical bar will appear in the top left corner of the display indicating an error has
been detected. If the error reporting function is enabled, error messages will be displayed as separate
menu pages. The rst line of the error menu page indicates the total number of errors and the second
line displays the error message. Measurement mode error messages are listed below.
Error Message
(display second line)
Type Description Corrective Action
Required
NO SIGNAL No signal from the vortex
sensor
No fl ow. Also check for any other errors dur-
ing power-on diagnostics. If there is a sensor
problem, contact ONICON.
LOW FREQ. Vortex frequency is too low Check for fl ow rate lower than specifi ed mini-
mum. Contact ONICON.
HIGH FREQ. Vortex frequency is too high Check for fl ow rate higher than specifi ed maxi-
mum. Contact ONICON.
LOW FLOW Flow rate lower than speci-
fi ed range
Converter will continue to display actual fl ow
rate. However, accuracy of measurement may
suffer.
HIGH FLOW Actual fl ow rate higher than
specifi ed range
Corrective action depends on application pro-
cess. If the fl ow rate exceeds the maximum
value it may damage the sensor physically.
INV. CONFIG. Confi guration data in non-
volatile memory is not valid
Contact ONICON.
ISO FAIL Checked
during
power-
on only
Sensor isolation has failed Contact ONICON.
AMP FAIL Pre-amplifi er section has
failed
Contact ONICON.
PIEZO FAIL Piezo wires broken Contact ONICON.
CHECK INST Flow signal quality is bad Check: 1) Flow rate, if OK; 2) Check for
excessive pipe vibration and upstream fl ow
disturbances; 3) Contact ONICON.
LOW SIGNAL Vortex signal amplitude too
low
Check: 1) Flow rate, if OK; 2) Contact ONI-
CON.
HIGH SIGNAL Vortex sensor signal
amplitude too high
This occurs in cases of high density medium.
Check 1) Flow rate, if OK 2) Contact ONI-
CON.
LOW.TEMP.PHY. Operating temperature is
lower than the physical limit
Take corrective action depending on the pro-
cess.
HIGH.TEMP.PHY. Operating temperature is
higher than the physical limit
Take corrective action immediately. This will
cause damage to the shedder bar as well as
to the electronics.
T.SENS.SHORT Temperature sensor/wires
short circuit
Indicates a fault in the temperature sensor.
Contact ONICON.
T.SENS.OPEN Temperature sensor open
circuit
