West Mountain Radio Operating Manual
Cold Start
The PWRguard PLUS will automatically reset from a
cold start condition.
GREEN LED –
Output ON
When the source voltage is between 11.0 and 15.0
Volts (nominally 13.8 volts), the large green LED will
light showing that the output is ON. The small LED,
being off, indicates the PWRguard PLUS is in Manual
Reset Mode.
RED LED –
Hi-Fault
The RED LED (Hi-Fault) will light whenever the input
voltage exceeds 15.0V. The GREEN LED will go OFF
and there will be NO output voltage. In the
Manual Reset Mode when the input voltage returns
to less than 15.0V, the RED LED will flash indicating
a return to safe voltage condition. The PWRguard
PLUS can then be manually Reset, thereby
repowering the load and lighting the GREEN
LED.
YELLOW LED
– Low-Fault
The YELLOW LED (low-fault) will light whenever the
input voltage drops below 11.0V. This LED will also
light briefly if there are momentary dips below
11.0V. This feature assures correct operation during
turn-on surge currents and during SSB or CW
transmission when powered from a battery supply.
The voltage may drop each time the power
requirement peaks. If the voltage continues to be
below 11.0V for more than 5 seconds, the Yellow
LED will light continuously. This state will continue
if the voltage is continuously below 11.0V and the
battery is nearing its drained state. The GREEN LED
will go OFF thereby turning the output OFF. The
PWRguard PLUS will remain OFF. When the input
voltage returns to 13.0V, the YELLOW LED will begin
to flash indicating the supply voltage has recovered.
The PWRguard PLUS can then be Manually Reset,
thereby, relighting the GREEN LED and re-powering
the load.
Manual to
Auto Reset
To restore auto mode, hold the reset button down
again for 5 seconds. The small green LED will light.
