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.
Check for a potential short circuit condition.
Confirm that the load current draw does not exceed the BP current rating.
Use the BP to control the remote on/off switch on loads with high inrush currents, rather than directly powering/disconnecting the DC supply.
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.
Confirm that the load current draw does not exceed the BP current rating.
Check for loose/high resistance connections and ensure that appropriate gauge wiring is used in the installation.
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.
Switch off/disconnect loads and recharge the battery.
Check charging system and battery for proper operation.
E4: Over voltage
Over voltage protection is activated in the event that the input voltage exceeds 64V.
Confirm the configuration of all charging devices in the system - particularly system voltage and charge voltage settings.
Check charging system for proper operation.
Confirm BP system voltage configuration is correct.
