Fault LED indicator blink, LCD displaying ‗Current Err‘
Probable Cause: Charging current in three phases is unbalanced.
Solution: Disconnect solar modules and restart the eTracer-BND; if the fault still exists,
please contact the supplier to make maintenance.

Fault LED indicator blink, LCD displaying ‗Over Volt‘
Probable Cause: solar modular output is too high.
Solution: Check solar component parameters matching; the controller will disconnect
the input if the voltage is over 150V and will Recovery below 145V.

Fault LED indicator blink, LCD displaying ‗Over Temp‘
Probable Cause: Heat sinks operational temperature is quite high to 85 º C or above.
Solution: The controller will automatically stop working. When the temperature is
below 75 º C, the controller will resume to work.

Cannot connect to the controller via RS-485 or RS-232
Probable Cause: RS-485 serial baud rate setting error or serial-USB adapter incorrect
configuration.
Solution: Check serial baud rate is set to 115200bps or not and choose the right COM
port; If using a serial-USB adapter, verify that the adapter software is installed and a
serial COM port has been mapped.
5.3 Maintenance
The following inspections and maintenance tasks are recommended at least two times
per year for best controller performance.

Check that the controller is securely mounted in a clean and dry environment.

Check that the air flow and ventilation around the controller is not blocked. Clear all
dirt or fragments on the heat sink.

Check all the naked wires to make sure insulation is not damaged for serious
solarization, frictional wear, dryness, insects or rats etc. Maintain or replace the wires if
necessary.

Tighten all the terminals. Inspect for loose, broken, or burnt wire connections.
