Rev 08 13-04-2021
APPENDIX
Error/ Warning Codes
E0: Calibration failure
Internal malfunction – calibration data failure/missing
����
Contact dealer for support – Fault is not user correctable and SBP requires replacement
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 SBP current rating
3. Use the SBP 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
P2: Over temperature warning
Urgent intervention required to prevent load disconnection
Internal temperature close to the limit. Over temperature protection will be activated if temperature continues to rise
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 SBP 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 SBP unit in a location exposed to high temperature or radiant heat - relocate SBP to a cooler position or provide additional active cooling
P3: Under voltage warning
Urgent intervention required to prevent load disconnection
Under voltage protection will be activated in 90 seconds if no action is taken
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 64 V
����
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 SBP system voltage configuration is correct
E5: Configuration failure
Internal malfunction - configuration data failure/missing
����
To recover the SBP from this condition;
1. Reset the unit to factory defaults under - Settings > More options > Reset to defaults
2. Disconnect all power and wait 3 minutes before reconnecting
3. Reconfigure the unit as required
E6: Reference voltage failure
Internal malfunction - reference voltage failure/missing
����
Contact dealer for support - Fault is not user correctable and SBP requires replacement
E7: BMS lockout
BMS lockout protection is activated in the event the external BMS requests the SBP to consecutively disengage and then re-engage 3 times (typical behaviour during a shut down due to low cell
voltage)
Once E7 is activated the SBP will remain disengaged until input voltage exceeds 52 V
����
1. Check BMS error codes/log to identify the cause of shut-down and rectify issue
2. Switch off/disconnect loads and recharge the battery
3. Check wiring between BMS and SBP Remote terminal
4. Check BMS for proper operation
E8: Reverse current
Reverse current protection is activated in the event that reverse current flow is detected
CAUTION: SBP is designed to allow or prevent current flow from IN to OUT terminals ONLY. Reverse current flow is strictly forbidden and may permanently damage the SBP.
����
1. Check that the SBP installation orientation is correct - current flow must be from IN to OUT (refer to example wiring diagrams)
2. Confirm that no charging sources are inadvertently connected to the SBP OUT terminal/circuit
3. If the SBP is used to disconnect a charge source, confirm that no loads are inadvertently connected to the SBP IN terminal/circuit
