Code

Fault

Mode

Possible Cause

Solution

Low Voltage Shutdown

Mitsubishi Inverter 0930

ALL

Under voltage

Check power supply and 24Vac before and during operation

ALL

Check power supply wires

ALL

Check 24Vac transformer tap for correct power supply voltage

Carel Inverter 1860

ALL

Input power supply phase loss,

three-phase power supply

unbalance

Check the input power supply phases to the drive, reduce motor

power (speed).

ALL

Motor cable disconnected

Check the connections of the motor cable.

ALL

The drive has detected a

ground current too high

Check ground insulation of the motor and wires.

ALL

• It indicates a small earth fault

on the motor

• The current measurement

chain (sensors, op amps,

shunts, ..) is damaged

Check tightness/wiring of the inverter/compressor cables. If properly

wired, then permanent damage to the motor.

ALL

Excessive external load (e.g.

fans) connected to the DCbus

Check external loads conneted to the DCbus terminal; especially

when the external load starts.

ALL

Excessive external load (e.g.

fans) connected to the DCbus

Check external loads conneted to the DCbus terminal; especially

when the external load starts.

ALL

Incompatibility between

compressor uSafety

parameters that characterize

the inverter as a PEC and the

inverter size

Check that the compressor uSafety parameters are adequate. Check

the compressor-inverter combination. Inverter probably too small.

Low Leaving Air temp

ALL

Low EAT

Bring EAT into range

ALL

Check unit capacity

Run mode to check unit capacity

ALL

Bad thermistor

Check temp vs. resistance curve per calculator

ALL

Incorrect airflow

Check airflow and reduce if nessesary.

ALL

Improperly installed airflow

sensor

Check installation

High Leaving Air temp

ALL

High SAT

Bring SAT into range

ALL

Low airflow

Increase airflow

ALL

Bad thermistor

Check temp vs. resistance curve per calculator

ALL

Improperly installed airflow

sensor

Check installation

Low Subcooling

ALL

Low charge

Check unit capacity in mode check

ECM Blower Motor Fault

ALL

High level fault condition

See low level faults (81-86)

ECM Lost Rotor Fault

ALL

Check blower assembly

Blower wheel set screw loose

ALL

Check blower assembly

Blower wheel dragging

ALL

Check blower assembly

Blower wheel locked

ECM Current Trip Fault

ALL

Low input voltage

Check input voltage

ALL

Bad ECM

Replace motor

ECM temp Limit Fault

ALL

High ambient motor temp

Reduce cabinet temp

ALL

Dirty motor housing

Clean motor

ECM Locked Rotor Fault

ALL

Debris in blower assembly

Check blower and clean assembly

ALL

Blower wheel draging

Check blower assembly

ALL

Bad motor bearing

Replace motor

ECM Over Voltage Fault

ALL

High input voltage

Check input voltage

ALL

Bad ECM

If nothing is found from other solutions, replace motor
