Alarm – High
Input Power
Detected at
Amplifier Input
<0.8V
Alarm – RF input power exceeds
maximum power threshold level. To reset
the alarm, it is necessary to reduce RF
drive signal level and reapply RF input
power (The alarm will remain illuminated
after RF input power is removed)

Digital Output
<0.8V
Alarm – Low fan speed or locked rotor
detected. May require fan maintenance or
replacement if defective.

VSWR Detected
at Amplifier
Output
<0.8V
Alarm – > 3:1 VSWR at the amplifier
output was detected. Amplifier output is
shutdown. To reset the alarm, it is
necessary to remove the high VSWR from
the amplifier output and reapply RF input
power (the alarm LED will remain
illuminated after RF input power is
removed)
