10.3 Warning & Status Messages
Warnings, errors and status messages appear on the second top line of the display. When there is more than one message to be
displayed then the display will cycle between them, unless an error is URGENT. Urgent may need user intervention and can only be
cleared by pressing 'delete' or the cause of the error being remedied. URGENT errors are marked as such in the interpretation.
Status messages may be hidden until normal and urgent errors are redressed. Normal errors, such as "Code is invalid", are auto-
matically removed after a period of time. All errors can be removed by pressing 'delete' but with most serious and urgent errors,
they may be generated again after a
minute or so.
Please check the Response associated with the given error and perform any required actions before contacting your GF sales
representative.
Flow rate errors & messages
No flow signal
Flow computation fault
Velocity Out of Range
Separation distance impossible
Heat Meter Errors & Messages
RTD Cold Sensor fault
RTD Hot Sensor fault
58
Interpretation: URGENT: The transducers cannot send or
receive signals.
Response: Firstly check that all cables are connected, trans-
ducers are on the pipe correctly with sufficient couplant on
the face.
This condition could also be due to a partially empty pipe,
aerated liquid, particulate content too high or when the con-
dition of the pipe being measured is poor.
Interpretation: URGENT: An internal error
occurred when computing flow.
Response: Restart the flowmeter. If the problem persists,
contact your GF sales representative.
Interpretation: The instantaneous flow velocity has, at least
temporarily, exceeded a specified maximum.
Response: This is an unusual condition. It is not fatal and
may occur sporadically. If it persists, check your installation.
Interpretation: The calculated sensor separation was less
than zero.
Response: Check all the site parameters and the sensor
chosen.
Interpretation: URGENT: The cold sensor probe is either not
connected or is faulty.
Response: Check the probe is connected. If you are running
a unit containing a heat-meter and the probe is not connect-
ed, you may simply delete the error and continue. This error
may be observed at start-up with no RTD probes connected.
In this case the error will be automatically deleted after 30
seconds.
Interpretation: URGENT: The hot sensor probe is either not
connected or is faulty.
Response: Check the probe is connected. If you are running a
unit containing a heat-meter and the probe is not connected,
you may simply delete the error and continue. This error may
be observed at start-up with no RTD probes connected. In
this case the error will be
automatically deleted after 30 seconds
