Figure 5: Second Battery Protect in between a battery charger or MPPT solar charge controller and a
Li-ion battery
The second BP replaces a Cyrix-Li-charge relay (advantages: lower power consumption, alarm relay).
(not applicable if the charger has remote on-off contacts and can be controlled with an interface cable between the BMS and the charger)

Choose program for this application.
Caution: uncontrolled reverse current will flow through a Battery Protect if Vout > Vin. Therefore never use a Battery Protect for battery to
battery charging.
APPENDIX

Error Codes

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
����
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
