5 Troubleshooting
T
he PHOENIX L300i is equipped with comprehensive self-diagnostic facilities. If an
error or warning condition is detected it is indicated via the LC display to the oper-
ator.
An audio signal is generated when an error or warning occurs. The frequency
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 3.11.)
5.1 Hints for Troubleshooting
Warnings will be indicated
- when the PHOENIX L300i 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 PHOENIX L300i will indicate a message on the LC display and will remain in
the standby 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 PHOENIX L300i can be
used again (possibly with some restrictions). As long as a warning status exists the
status line shows a warning triangle.
Errors are events which force the PHOENIX L300i to interrupt its measurement
operations. In this case the PHOENIX L300i closes all valves except valve 2a
(standby mode).
Error messages remain on the LC display until the message has been acknowl-
edged by pressing „Restart“ (key no. 8). After that, the PHOENIX L300i restarts
with a new run-up procedure. In some cases it may be helpful to check some set-
tings or measured values before the PHOENIX L300i restarts. Therefore it is also
possible to press „Menu“ (key no. 4 or Menu key) to enter the PHOENIX L300i
menu. After leaving the menu the same error message will be displayed again.
Under extreme conditions (unknown software errors, excessively high electromag-
netic interference levels) the built-in „watchdog“ circuit will prevent uncontrolled
operation of the PHOENIX L300i. This watchdog will cause the PHOENIX L300i to
restart. After having done so, the instrument will be running in the standby mode.
No error message will be output.
