Indication Of Fault Conditions - Ham radio HF2013DX-A Instruction Manual

INDICATION OF FAULT CONDITIONS

The HF2013DX-A has the following indicationson the front LCD panel:
G2
HV
IA
FAULT
OPR
STBY
WAIT
TEMP
G1MAX
Should a fault condition appear during the tuning or operation of the amplifier the
safetycircuits of HF2013DX-A will react. The amplifier will be turned to STBYmode. After
approx. 5seconds the control circuits will switch the amplifier back to OPR. If the fault repeat 3
times, the control circuits will turn the amplifier to STBY. You must toggle the
switch to reset this fault condition. After the reaction of safety circuits the FAULTLCD will be lit
up for approx. 5 to 10 secdepending on the nature of the fault.
