  • Page 18: Inverter Fault Tracing

    Inverter Fault Tracing Conveniently, the fault coding and trip logic are similar in all Honeywell NX inverters. This table thus applies to both NXS and NXL HVAC. Fault Fault Possible Cause Correcting measures Code Overcurrent Frequency converter has detected too Check loading.
  • Page 19 Fault Fault Possible Cause Correcting measures Code Motor under load Motor underload protection has tripped. FAN: check that belt is not broken. PUMP: check that pump is not dry. EEPROM Parameter save fault: Contact the technical support. checksum fault - Faulty operation. - Component failure.
