West Mountain Radio
Operating Manual
Installation
1. Install the PWRguard PLUS between the power source and the
loads to be protected.
NOTE: The unit comes fitted with Powerpole® connectors for ease
of installation into your power system.
Input (power source) connects on the left side of the case.
Output (load) connects on the right side of the case.
Make sure that you only connect the RED lead to POSITIVE, and the
BLACK lead to NEGATIVE.
2. Install the unit in a cool dry location. The case may be fastened
down using the mounting holes on the flanges.
3. The external sense terminal is located within the unit. Remove the
case and locate the small terminal-block on the left hand side. The
terminal nearest the edge of the board pr5VDC through a
330 ohm resistor and the right terminal is the sense input.
The piezo buzzer alarm can be disabled by removing the jumper
from the terminal post marked “Buzzer”.
4. When the power supply is switched on, the PWRguard Plus unit will
become operational and the AUTO RESET and ON LEDs will
both glow green. If the AUTO RESET LED does not turn on, hold
the reset button down for 5 seconds until it does. If the YELLOW
LED (Low fault) comes on instead of the ON LED, it means that your
power supply or battery voltage is too low. PWRguard Plus requires
at least 13 (+/- 0.1) volts to become operational when turned on. If
supply voltage range is between 11-13V, you will need to manually
turn on by pushing reset.
This setup integrates PWRguard Plus into a UPS. The PWRGuard
Plus input is connected to the output of the Super PWRgate. The
PWRguard Plus output is connected to the input of the RIGrunner.
This setup will protect the battery from deep discharge after an AC
power loss, and all devices that are plugged into the RIGrunner from
under and over voltage. After AC power is restored, the battery will
be recharged through the Super PWRgate and PWRguard Plus will
reset the system.
