Fault indication

Additional information

Internal Fault

TRM-Error

A TRM card error has occurred. The

instance number is displayed at the end

of the fault indication.

Internal Fault

COM-Error

A COM card error has occurred. The

instance number is displayed at the end

of the fault indication.

Internal Fault

PSM-Error

A PSM card error has occurred. The

instance number is displayed at the end

of the fault indication.

8.2.2

Warnings

The warning message associated with the fault is found in the internal event list in the
LHMI menu

Main menu/Diagnostics/Internal events

. The message includes the date,

time, description and signal state for the fault. The current status of the internal fault
signals can also be checked via the LHMI in

Main menu/Diagnostics/IED status/

General

When a fault appears, record the fault indication message and state it when ordering
service.

in some actions such as

reading the configuration file,

startup etc.

Warning

DNP3 Error

Error in DNP3 communication.

8.2.3

Additional indications

The additional indication messages do not activate internal fault or warning.

The messages are listed in the LHMI menu under the event list. The signal status data is
found under the IED status and in the internal event list.
