Charger Control Modes
There are 3 automatic charge modes plus one manual ON-OFF to switch on and off the charger to give the
optimal charging current to the auxiliary battery.
Automatic Ignition Control Mode
It synchronizes ON/OFF of the DC-DC charger with the car’s ignition.
This mode requires connection to the car’s Ignition Signal
Terminal 15
see wiring diagram (page 10)
electrical circuit which gives out a positive DC Voltage from the car’s electrical wiring when the ignition is
turned on. The ignition control will set to ON once the
Ignition Pin 7
is applied with 9-32V voltage. The
charging operation stops when Ignition is off & engine stops running.
This mode is recommended for all alternator types including Europe 6, 6+plus with start/ stop energy saving.
Manual Control
You can wire a contact switch with one end to the
Ignition Pin 7
and the other to
Vout for Ignition Pin 8
.
Shorting both pins will turn on the charger, disconnect will turn off the charger.(page 9)
Vibration Sensor Control Mode
The built in vibration sensor with special software control turns on the charging when trains of vibrations are
detected. Installation is simple and quick and without touching the car’s electrical system for the sensor to
work.
Enable build-in vibration sensor
The built-in vibration sensor is enabled by connecting the
T+ pin 1
to
Vout for Ignition pin 8
.
Initially the charger output is off when the vibration sensor is in standby mode. Continuous vibrations with
over 8 minute duration triggers it into the active mode . The output will be switched ON for about 100
seconds continuously. Any further vibration during the 100 seconds active mode, will extend the output ON
for another 100 seconds. The output will be switched OFF if no more vibration within 100 seconds of last
vibration.
Over- riding Ignition Feed by Vibration Sensor
Built-in vibration sensor when enabled dominates the control of output and over- rides all other Modes
including the Ignition Feed. That is only vibration can make the charger start charging with output ON.
To disable the Vibration Sensor:
Take out the connection between the
T+ pin 1
from
Vout for Ignition
pin 8
.
CAUTION:
DO NOT USE VIBRATION SENSOR CONTROL WHEN CAR IS ON FERRY, TRAIN OR
OTHER TRANSPORT PLATFORMS WITH REGULAR VIBRATIONS & SHOCKS.
REMARK
Once the Vibration Sensor Mode is disabled, the charger will return to the last selected mode.
If you are not sure about your last selected mode, you can set the charger to your desired mode.
