5.3.4 Warning threshold setting menu
As mentioned in the introduction the amplifier offers three settable warning
thresholds. Each one is compared with the level of one of the machine’s operating
parameters. The results of the comparison are available on the telemetry connector,
on the contacts of the optional external telemetry card and may be read on the
display as “O” (open, i.e. false result) or “C” (closed, i.e. real result).
Two of the settable thresholds (
P
o
w
e
r
G
oo
d
) refer to the emitted power level
whereas the reflected power quantity (
R
e
fl
ected
War
ning
) is checked for the third
one.
The limit voltages of the quantities monitored by the warning thresholds for are
the follows:
•
Forward Power
5000 W
(mod.
PJ5000U-K
)
•
Forward Power
3500 W
(mod.
PJ3500M-C
)
•
Reflected Power 350/500 W
Proceed as follows to change the values of the warning thresholds:
•
Select the line to be changed (with the UP and DOWN keys)
• Press the ENTER key
• Change the threshold value (UP and DOWN keys)
• Press ENTER to confirm
The figure below shows a configuration example of this menu.
In this example the alarm thresholds are as follows:
•

)
•
