8 Error And Warning
Messages
The PhoeniXL is equipped with a comprehensive self-diagnostic facilities.
If an error or warning condition is detected it is indicated via the LC display
to the operator.
An audio signal is generated when an error or warning occurs. The fre-
quency changes every 400 ms from 500 Hz to 1200 Hz and vice versa so
that the signal stands out well from ambient noises normally encountered.
Error and warning messages are logged and can also be displayed at a
later time through the menu information (Please refer to Chapter 6.7)
8.1 Hints
Warning MessagesWarnings will be indicated
when the PhoeniXL detects an abnormal condition or
when it wants to remind the operator of something (e.g. a request for
calibration or a service timer has expired).
The PhoeniXL will indicate a message on the LC display and will remain in
the Stand-by or the measurement mode.
Warning messages will remain on the LC display until the warning has
been acknowledged by pressing „OK“ (Key no. 8). After that the PhoeniXL
can be used again (possibly with some restrictions). As long as a warning
status exists the status line shows a warning triangle (5.4.3).
Error MessagesErrors are events which force the PhoeniXL to interrupt its measurement
operations. In this case the PhoeniXL closes all valves exept valve 2a
(Stand-by mode).
Error messages remain on the LC display until the message has been ack-
nowledged by pressing „Restart“ (key no. 8). After that, the PhoeniXL
restarts with a new run-up procedure. In some cases it may be helpful to
check some settings or measured values before the PhoeniXL restarts.
Therefore it is also possible to press „Menu“ (key no. 4 or Menu key) to
enter the PhoeniXL menu. After leaving the menu the same error message
will be displayed again.
Under extrem conditions (unknown software errors, excessively high elec-
tromagnetic interference levels) the built-in „watchdog“ circuit will prevent
uncontrolled operation of the PhoeniXL. This watchdog will cause the
PhoeniXL to restart. After having done so, the instrument will be running in
the Stand-by mode. No error message will be output.
