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
Interpretation: The [measurement source] chosen is not compatible
with the desired output [function].
Response: Choose another (compatible) measurement source and /
or function.
Interpretation: The [internal] board failed to respond to a discovery
message and has been taken offline momentarily.
Response: This error may be the result of a temporary computational
overload. Go to the Options screen and check the board status. Try
first to restart and if the error still persists, reset the flowmeter. If
after reset, all boards do not report as "OK", note the failing board
and call your distributor.
Interpretation: The current loop is either open circuit (not connected)
or possibly a short circuit resulting in internal components
overheating.
Response: Either turn the current loop off if it not required, or
connect it as needed. Ensure a suitable load is being placed on the
current loop and it is not driving into a direct short circuit. The alarm
can be cleared by pressing delete, but if the condition is not rectified,
it will return in approximately one minute.
Interpretation: This message is for information only. It is generated
when alarm conditions have been met for the current loop.
Response: Clear the alarm by deleting it and attend to the fault. De-
leting the alarm does not stop the error current being generated as
long as the fault remains.
Interpretation: This message is informative only. It is generated
when alarm conditions have been met for digital output [n].
Response: Clear the alarm by deleting it and attend to the fault.
Deleting the alarm does not stop the output generating the alarm as
long as the fault remains.
Interpretation: An attempt was made to define the error current
within the normal working range of the current loop. For example,
this error would be generated if the working range were 0 to
16mA and the error current was set to any value below 16mA. The
flowmeter will try to redefine a valid error current.
Response: Redefine the error current or change the working range if
the calculated value is not desirable.
Interpretation: The entire range of the current loop (0 to 24mA) has
been defined as valid, so an error current is not possible. In this case
the alarm function is disabled.
Response: If an error current is required, redefine the working
region to be a smaller range.
