TROUBLESHOOTING
Bypass TEMP: (as seen on the TFT display)
The LA-1K is in
BYPASS
to protect itself from high temperatures. The
temperature will show in red when it exceeds 70°C. When the heatsink
temperature exceeds 100°C
BYPASS TEMP
will show on the display.
Solution:
Allow time for the heatsink to cool down below 70°C.
Operate (OPR) will automatically return. Verify that the side vents are
clear from obstructions.
High SWR or prolonged transmission in carrier modes may cause
elevated temperatures.
TX OVERDRIVE: (as seen on the TFT display)
This displays when the drive level exceeds approximately 60W.
Solution:
Reduce the drive level to prevent displaying this fault.
Vd: (as seen on the TFT display)
The LA-1K is in
BYPASS
to protect from loss of +50V, drain voltage supply.
The fault should clear in a few seconds. This can occur when operating
on 120V if the drain current (Id) exceeds 32A.
Solution:
Switch the supply voltage to 240VAC or if operating on 120VAC is desired,
reduce drive power.
