One or more PSU are in thermal derating so
that the RF output power is reduced.

PSU VOLTAGE DERATING
The RF section has been turned off so that the
fans can quickly cool the apparatus.
The apparatus works in a combined Tx.
High reflected power has been detected so
that the apparatus is adjusting the RF output
power according to an algorithm.
The PLL of the VCO is no longer locked to the
set frequency.
The exciter serial communication has stopped
working correctly.
The audio input level has remained lower than
the minimum set level for the set time.
The RF out power is rising up to 2/3 of the tar-
get after which a “−3dB” alarm has occurred.
Fan no.1 has stopped working properly.
Excessive modulation is occurring (too high
frequency deviation).
Fan no.2 has stopped working properly.
If the thermal probes installed are more than
one, it means the fault of one of these because
its read value is significantly different from the
expected one.
RF output power oscillation is detected and
the apparatus attempts the “Three Block Out”
recovery protection.
The malfunction has not disappeared during
the automatic protection time and the appara-
tus was stopped.
The user−defined environmental temperature
limits in “User Alarms Data” have been
exceeded.
The user−defined RF temperature limits in
“User Alarms Data” have been exceeded.
The user−defined PSU temperature limits in
“User Alarms Data” have been exceeded.
The user−defined RF current limits in “User
Alarms Data” have been exceeded.
The user−defined PSU current limits in “User
Alarms Data” have been exceeded.
The user−defined RF forward power limits in
“User Alarms Data” have been exceeded.
The user−defined RF reflected power limits in
“User Alarms Data” have been exceeded.
The RF output power measurement is not
reliable.
The apparatus works by drawing current from
the UPS.
Internal serial communication timeout. The
apparatus has stopped working.
A thermal probe is unreliable and its reading is
discarded.
VDS voltage too low. The amplifier section has
been stopped and will remain so until the
disappearance of the cause.
An overshoot of RF output power respect to
the target is occurred.
One or more PSU are in voltage derating.
