MAIN ALARM ALARM DESCRIPTION
High Power Amplifier Communication Control Module cannot communicate with Power Amplifiers
High Power Amplifier Active Alarm Current alarm on one or more Power Amplifiers
Exciter Fail Control Module cannot communicate with Exciter
ALC Max Automatic Level Control set to maximum and not able to
drive the output power required
uC Communication Fail Web Server cannot communicate with microcontroller
Interlock Failure Interlock protection disabled
RF Mute RF Output muted by itself or by an external command
Over Power Output Power exceeded allowed limit
Reflected Power Reflected Power exceeded the minimum allowed!
Output Power Zero Output power not detected by Directional Coupler
Reduction Power by Reflected Power reduced to comply with reflected power limit
Reduction Power by High Power Amplifier Power reduced to comply with maximum power provided by
each power amplifier
Reduction Power by HPA High
Temperature When the HPA reaches 87 °C (188.6 °F), it reduces the
power by 3dB. Returns the rated power when the
temperature is restored to 80 °C (176 °F).
