Protection Function / Fixes
LED is Red, what do I do?
Protective Function
Potential Fixes
Over-Voltage Protection;
Under-Voltage Protection
1.
Use a multi-meter to check the voltage of the battery bank to
confirm whether the starter battery or house battery is above
specification (16V) or below the specification (8V)
2.
If above the voltage specification, disconnect all loads and
chargers from the battery and allow the battery to stabilize.
This may take a few hours.
3.
If below the voltage specification, you will need an external
charger to bring the battery voltage to the minimum set point
on the DCDC. The under-voltage protection may not be
showing an indicator light.
Reverse-Polarity Protection
1.
Use a multi-meter to also verify whether your poles are
reversed. Setting your multi-meter to DC Volts, probe the
positive line onto the positive battery terminal and probe the
negative line to the negative battery terminal. If the DC reading
is negative, your poles are reversed.
2.
Switch the poles to resume normal operation
High-Temperature
Protection
1.
If voltage checks out fine, then the installation area may be
too hot for the DCDC to operate.
2.
Turn off any loads from the DCDC and if you have a
temperature sensor, measure the temperature to make sure it
is not outside of working specification (50®C)
3.
Ventilate the installation area, or let the unit sit until it has
cooled down via temperature sensor or your touch.
4.
The high-temperature protection is automatic and will resume
normal operation upon detecting lower
temperatures/operational temperatures.
Short Circuit Error
If the troubleshooting steps or protection function steps are
ineffective at fixing the DCDC, then it may be experiencing an internal
short circuit error. The LED will be permanently on and cease to
function, by which it will need to be replaced.
