5.3.4 Alarm Menu (Alm)
This menu shows any alarm conditions occurring during machine operation. Alarm
thresholds are preset at the factory.
Menu 7
FWD
Counter of alarm conditions triggered by forward power.
RFL
Counter of alarm conditions triggered by reflected power.
INP
Counter of alarm conditions triggered by input power.
Reset Alm
Alarm counter reset.
Alarm conditions are numbered from 1 to 10 and reflect the following situations:
forward output power too high, reflected output power too high and input power
too high.
Alarm monitoring cycle is as follows: when an alarm condition is detected, alarm
counter increases by 1 unit, machine goes into lock-out state and the display
shows the cause for the stop. After 15 seconds, the machine attempts to re-start;
if a new alarm condition is detected, cycle is repeated over and over again up to
10 times maximum.
If machine re-starts successfully, all alarm counters are reset after 30 minutes’
regular operation. After 10 alarm conditions triggered by the same cause, the
machine goes into fault lock-out mode, a lock-out mode warning appears on the
display and the “FAULT/LOCK” LED turns on.
After the alarm condition has been rectified, the counter can be reset by highlighting
“Reset Alm” and holding down the
ENTER
key for some time.

though the user is browsing system menus) and the following messages
are displayed:
