5.3.7.1
WARNING FOLDBACK REFLECTED POWER
The unit is provided with a reflected power level proportional protection: in case the output
reflected power exceeds the foldback threshold value the unit enters in warning mode and the
output forward power is proportionally lowered to maintain the reflected power under the foldback
threshold level.
The folbadck threshold is indicated as percentage of nominal unit power. Standard factory
calibration is 15% of nominal power.
Fig. 5.37 – Foldback Reflected menu
To change the foldback threshold level, press the OK key to enter the program mode (blinking
arrow in second row on the right). Press UP or DOWN keys to select desired value. Press OK key
to confirm or ESC key to exit routine without saving.
MIN value: 0%
MAX value: 100%
STEP: ±1%

5.3.7.2
WARNING REFLECTED POWER
In this menu it is possible to set a threshold value for a reflected power warning in similar way to
the previous menu.
The presence of this warning does not alter in any way the output forward power unlike by the
foldback reflected warning.
The Warning Reflected threshold is indicated as percentage of nominal unit power.
