When a fault condition occurs during the tuning or operation of the amplifier, the safety circuits
will
block transmitting
. The amplifier stays in
OPER
mode. After approx. 1 sec the control
circuits will automatically switch the amplifier back to the transmitting mode. If the problem
persists, the safety circuit will react again and the appropriate fault message will appear on the PA status
screen.
If the fault repeats 3 times during a 10 seconds interval, the safety circuits will turn the
amplifier to STBY mode. Cancelling a fault condition takes a short press of the STBY/OPER
button. The PA will stay in STBY mode.
NOTE:
All the warning and fault messages are stored in the onboard memory. You can display particular
warning messages and particular error messages. They are stored up to 20 at a time to the memory. You
can view them on the menu display. If the error memory is full, every new message will delete the
oldest one in the stack. It means that every only the last 20 messages are visible on the display.
This is an example from a previous attempt
at transmitting when the antenna was
disconnected from the PA .
Reflected power was higher than 277W and
a warning message “Reflected power too
high” appeared.
If you touch the “LAST EV” box on the PA
touch screen it will display the warning
details.
In the case of some hardware failure or if
your power amplifier is not working properly,
please contact the manufacturer or your
local dealer.
Never try to change or move any part inside the amplifier except the tube or fuses.
Substitution of parts may void intrinsic safety!
