Trouble Shooting Guide 22
D250S Dual
• Power LED is not lit.
Explanation: The target battery voltage must be above 9V.
• The Power LEDs are flashing rapidly or glowing faint.
Explanation: The charger has entered power save mode due to low voltage.
• The charger does not start charging.
Explanation: In order to start charging the supply voltage needs to be above
13.1V on the supply battery input or above 11.5V on the solar input. The
voltage on the target battery also needs to above 5V. The solar voltage also
needs to be higher than the alternator input voltage.
Test: Test Use a voltmeter to verify that the voltages are within the levels
specified above.
• The charger does not stop charging the target battery even though the
alternator or charger on the supply battery has been turned off
When charging of the supply battery is turned off the voltage will drop. The
output power of the charger is dependent on the input voltage. With lower
input voltage the output power is lower. Due to this it may take some time until
the charger stops. It will however not drain the supply battery, the charger will
turn off when the voltage has dropped below 12.8V. If there is power on the
solar panel, this will be used to charge the target battery.
• Is flashing.
Explanation: The charger has detected a problem. This LED is always flashing
with some other LEDs lit to tell what the problem is.
If only the power on lamp is lit then the temperature at the target battery is too
high. The charger will not charge the battery if the temperature is above 65 °C,
as soon as the temperature is lower, the charging will automatically restart.
If the alternator or solar LED or both are lit when the error led is flashing a
connection problem is detected with the target battery, check the connections.
