Amplifier is too hot
Most of the safety circuits are preset for two levels of activation. The first level is a warning level.
In such a case a warning message appears on the display, but the power amplifier will stay in
normal operation. See the table above for warning and fault conditions.
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 only the last 20 messages are visible on the display.
This is an example from a previous attempt at
