6.1. Error and Warning codes

This appendix gives a list of error and warning codes and possible solutions.
E1: Short circuit
Short circuit protection is activated in the event of a short circuit, an overload condition or excessive inrush current - such as when
attempting to directly power an inverter or inverter/charger.
1. Check for a potential short circuit condition.
2. Confirm that the load current draw does not exceed the BP current rating.
3. Use the BP to control the remote on/off switch on loads with high inrush currents, rather than directly powering/disconnecting
the DC supply.
4. Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the installation.
E2: Over temperature
Over temperature protection is activated in the event of excessive internal temperature.
1. Confirm that the load current draw does not exceed the BP current rating.
2. Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the installation.
3. Do not install the BP unit in a location exposed to high temperature or radiant heat - relocate BP to a cooler position or
provide additional active cooling.
E3: Under voltage
Under voltage protection is activated in the event that the input voltage drops below the under voltage limit selected for 90
seconds.
1. Switch off/disconnect loads and recharge the battery.
2. Check charging system and battery for proper operation.
E4: Over voltage
Over voltage protection is activated in the event that the input voltage exceeds 16V (for 12V systems) or 32V (for 24V systems).
1. Confirm the configuration of all charging devices in the system - particularly system voltage and charge voltage settings.
2. Check charging system for proper operation.
3. Confirm BP system voltage configuration is correct.
