Emerson SERIES 600T Manuel D’Utilisation

Faults. Table 17 - Troubleshooting describes actions that may alleviate the condition or provide 

valuable information for technical support.

Faults that initiate an AUTOSHUTDOWN include: MISER, RUNOUT, PWR SPLY VOLT (at high 

speed), and will require Service level and higher to reset.

GROUND FAULT

Ground fault current out of range.

X

HW BUS OV

HW overvoltage. (hardware protection)

X

X PHASE OC

AC phase overcurrent. x = A, B, C.

X

IGBT OVRTEMP

IGBT overtemperature. 

X

VACUUM FAULT

Drag power exceeds 125W. 

X

RUNOUT FAULT

Runout higher than 2.9mil.

X

MISER FAULT

Miser voltage is higher than 5V.

X

BEARING

Magnetic bearing fault.

X

AUX POWER LOW

Auxiliary power supply voltage is low when the 

system is in Off mode. Configurable fault.

X

INTER PRCR COMM

Communication error with secondary DSP. System 

reboots.

X

PWR SPLY VOLT

Power supply voltage is lower than 19V. (Speed 

dependent; auto shutdown at high speed)

X

X

UNDEF PDP INT

Undefined PDP interrupt.

X

CURRENT OFFSET

AC motor current sensor error.

X

SW OV

DC bus voltage is higher than the threshold, which is 

service-configurable.

X

CHECKSUM

Calculated checksum does not match the stored 

checksum.

S

CONTACTOR TIME OUT

Bus voltage/current is not stable while trying to close 

or open contactor.

X

CONTACTOR CLOSE FAIL

Contactor failed to close on startup.

X

FAN OPEN

Fan open circuit or disconnected.

X

FAN SHORT

Fan short circuit.

X

PUMP OPEN

Pump open circuit or disconnected.

X

PUMP SHORT

Pump short circuit.

X

HW OVERSPEED

Hardware detected overspeed.

X

PRECHARGE PROTECTION Stop PWM when large voltage differential exists 

between internal and external bus.

X

BUS CURRENT OFFSET

DC current sensor error.

X

S - Indicates a Certified Service Provider will be required to reset system.

NOTE 
If a fault recurs after being cleared by the operator, and the condition persists, contact your
