Fault
AMP#1
AMP#2
AMP#3
AMP#4
The corresponding amplifier module
does not operate, for example,
because its supply line fuse is blown,
or a fault in the module itself.
1KW amplifier is in the bypass mode
and cannot transmit
Service is required
RF IN OVERLOAD
Excessive drive power supplied to the
RF IN input.
1KW amplifier is in the bypass mode
and will not transmit until the
condition is corrected
When using the amplifier with a
driver other than RM125/RM125R,
check the maximum transmit power
of the driver unit.
When using the RM125/RM125R,
first check for proper connection of
the control cable between the
RM125/RM125R AMP-CONT
connector and the 1KW amplifier
EXCITER CONTROL connector. If
problem persists, service is required
(adjustment of operating conditions
using the MONITOR program)
PWR OUT LATCH
Technical problem related to the
harmonic filter.
1KW amplifier is in the bypass mode
and cannot transmit
Service is required
TEMP OVERHEAT
Excessive internal temperature.
1KW amplifier is in the bypass mode
and cannot transmit until it cools
Wait for the amplifier to cool.
Check that the air intake vents and
exhaust vents are free. If condition
recurs, power down the amplifier
and clean the dust filters (the filters
are reached after removing the
intake covers, which are fastened by
four screws each)
Warning
PWR OUT
REDUCED
Internal temperature is too high.
1KW amplifier transmits at reduced
(half) power as long as problem
persists
See TEMP OVERHEAT
HIGH VSWR
Excessive reflected power.
1KW amplifier is in the bypass mode
and will not transmit until the
condition is corrected
Check the antenna feed cable,
starting from the RF OUT
connector, and up to the antenna.
Also check that no damage is
evident to the cables and to the
antenna itself
