Demand Start Adjust LED (5) (green) ON
Low Volts Adjust LED (5) (green) FLASHING
It is sometimes necessary to adjust the demand start sensitivity to overcome
what is called “Phantom Loads”. A phantom load is a load that tricks the
inverter into thinking it should be ON instead of in SLEEP mode.
To avoid total discharging of your battery the LD450-12 shuts down at a pre-
set low voltage. As all batteries are different, so too is the minimum voltage
they should be discharged to. The LD450-12 will leave the factory with a
setting of
11.0 volts
, change this setting if required.
The wiring of a house or a portable stereo system in standby are good
examples of a phantom load. These loads serve no purpose but yet can
increase battery drain by bringing the inverter ON. Hold the Mode button (7)
down until LED (5) comes ON, (approximately 1 second) indicating you are
ready to adjust this setting. The LD450-12 will leave the factory with a setting
of 4 watts. Now press the Mode button (7) until the desired value is sought.
LEDs (1) – (4) will return to Status after 20 seconds.
Hold the Mode button (7) down until LED (5) is FLASHING, (approximately
2 seconds) indicating you are ready to adjust this setting. Now press the Mode
button (7) until the desired value is sought. LEDs (1) – (4) will return to
Status after 20 seconds.
