Troubleshooting instructions
Always start troubleshooting with the following checklist if faults occur after commissioning
or during operation. The routine takes you directly to the cause of the problem and the
appropriate remedial measures.
Check the display
No display visible and no
output signals present.
1. Check the supply voltage
→
Terminals 1, 2
2. Check device fuse
85 to 260 V AC: 0.8 A slow-blow / 250 V
20 to 55 V AC and 16 to 62 V DC: 2 A slow-blow / 250 V
3. Measuring electronics defective
→
order spare parts
No display visible, but output
signals are present.
1. Check whether the ribbon-cable connector of the display module is
correctly plugged into the amplifier board
2. Display module defective
→
order spare parts
3. Measuring electronics defective
→
order spare parts
Display texts are in a foreign
language.
Switch off power supply. Press and hold down both the
P
keys and switch on
the measuring device. The display text will appear in English (default) and is
displayed at maximum contrast.
Measured value indicated, but
no signal at the current or
pulse output

Status signals on display (only HART 7)
The status signals provide information on the state and reliability of the device by
categorizing the cause of the diagnostic information (diagnostic event).
The status signals are categorized according to VDI/VDE 2650 and NAMUR Recommendation NE 107:
F = Failure, C = Function Check, S = Out of Specification, M= Maintenance Required
Category F (Failure)
A device error has occurred. The measured value is no longer valid.
Category C (Function check
The device is in service mode (e.g. during a simulation).
Category S (Out of specification
The device is operated:
• Outside its technical specification limits (e.g. outside the process temperature range)
• Outside of the configuration carried out by the user (e.g. maximum flow in parameter
20 mA value
)
Category M (Maintenance required
Maintenance is required. The measured value remains valid.

Error messages on display
Errors that occur during commissioning or measuring are displayed immediately. Error messages consist of a
variety of icons. The meanings of these icons are as follows (example):
– Type of error:
S
= System error,
P
= Process error
– Error message type:
$
= Fault message,
!
= Notice message
–
FLUID INHOM.
= Error designation (e.g. fluid is not homogeneous)
–
03:00:05
= Duration of error occurrence (in hours, minutes and seconds)
–
#702
= Error number
"
Caution!

Other error (without error message)
Some other error has occurred. Diagnosis and rectification
