This is caused by low intermediate circuit DC voltage. This can be caused by a missing supply voltage phase from a blown fuse or faulty isolator or contactor or internal rectifier bridge fault or simply low mains voltage. POSSIBLE FIXES: Check mains supply and fuses. It occurs when the voltage output from the inverter drops below the recommended level, leading to system failures, reduced equipment performance, or even. . Got through the ADC error, and now I have “X Axis High Voltage is Low”. There is around 96Volts (from T2) coming into the capacitor assembly labeled “135 Volt Power Supply” which appears to feed the Axis control boards. When the string output voltage is lower than the minimum input voltage of the inverter, there is no display on the inverter screen. Check AC/DC switches: Ensure that both the AC and DC switches are in the “ON” position. Verify battery connections: Inspect the battery terminals for corrosion and ensure they. .
