Diagnostics and troubleshooting

12.1

Troubleshooting

General errors

Problem

Possible cause

Remedy

Device is not responding.

Supply voltage does not match that
specified on the nameplate.

Apply correct voltage.

Supply voltage has incorrect polarity.

Reverse polarity of supply voltage.

Connecting cables are not in contact with
the terminals.

Check the connection of the cables and
correct if necessary.

No display

Onsite display is set too bright or too dark. • Set the local display brighter by

simultaneously pressing

O

and

F

.

• Set the local display darker by

simultaneously pressing

S

and

F

.

Connector for local display is not properly
connected.

Ensure connector is properly connected.

Onsite display is defective.

Replace onsite display.

Output current < 3.6 mA

Signal line is not wired correctly.

Check wiring.

Electronics unit is defective.

Replace electronics.

HART communication is not
working.

Missing or incorrectly installed
communication resistor.

Install the communication resistor (250

W

)

correctly.

Commubox is not properly connected.

Connect Commubox correctly .

Commubox is not set to "HART".

Set Commubox selector switch to "HART".

Device measures incorrectly.

Configuration error

Check and correct parameter configuration
(see below).

12.2

Diagnostic events

12.2.1 Diagnostic message

Faults detected by the self-monitoring system of the measuring device are displayed as a diagnostic
message in alternation with the measured value display.

Status signals

62) lists the messages that can occur. The ALARM STATUS parameter shows the

message with the highest priority. The device has four different status information codes according
to NE107:

A0013956

"Failure"

A device error has occurred. The measured value is no longer valid.

A0013957

"Maintenance required"

Maintenance is required. The measured value is still valid.

A0013959

"Function check"

The device is in service mode (e.g. during a simulation).

A0013958

"Out of specification"

The device is being operated:
• Outside its technical specifications (e.g. during warmup or cleaning processes).
• Outside the parameter configuration undertaken by the user (e.g. level outside of configured

range)
