PT EL. BROKEN
# 314
The temperature sensor is defective and temperature
measurement is no longer possible.
The measuring device uses the value specified in the
ERROR TEMPERATURE function ä 149.
Replace the amplifier board.
Spare parts.

NO T-SENSOR
# 316
The temperature sensor has failed or no temperature
sensor is available. The measuring device uses the value
specified in the ERROR TEMPERATURE function
ä 149.
Contact your E+H service organization.
!
Note!
• If the measuring device is intentionally operated with a
Prowirl 72 DSC sensor (without a temperature sensor), this
message has to be changed from a fault message to a notice
message (ä 173, ASSIGN SYSTEM ERROR).
• This error message may indicate that the maximum flow
velocity permitted has been greatly exceeded.

CHECK T-SENSOR
# 317
The self-monitoring function of the measuring device
found an error in the DSC sensor which can affect
temperature measurement.
!
Note!
The mass flow is calculated with the value entered in the
ERROR TEMPERATURE function ä 149.
Contact your E+H service organization.

CHECK SENSOR
# 318
The self-monitoring function of the measuring device
found an error in the DSC sensor which can affect flow
and temperature measurement.
!
Note!
The mass flow is calculated with the value entered in the
ERROR TEMPERATURE function ä 149.
Contact your Endress+Hauser service organization.
!
Note!
The error status can be changed from fault message to notice
message in the ASSIGN SYSTEM ERROR function (ä 173).
Please note that while this means a measured value is output
again, the error still has to be eliminated.
S

RANGE CUR.OUT
# 351
Current output: the current flow is outside the set range. 1. Change full scale value entered.
2. Reduce flow.
S
!
RANGE FRQ. OUT
# 355
Frequency output: the current flow is outside the set
range.
1. Change full scale value entered.
2. Reduce flow.
S
!
RANGE PULSE
# 359
Pulse output: the pulse output frequency is outside the
set range.
1. Increase pulse value.
2. When entering the pulse width, select a value that can still be
processed by a connected totalizer (e.g. mechanical totalizer,
PLC, etc.). Determine pulse width:
– Method 1: enter the minimum time for which a pulse has
to be present at a connected totalizer in order to be
recorded.
– Method 2: enter the maximum (pulse) frequency as a half
"reciprocal value" for which a pulse has to be present at a
connected totalizer in order to be recorded.
Example:
The maximum input frequency of the connected counter
is 10 Hz. The pulse width to be entered is: 1 / (2·10 Hz)
= 50 ms.
3. Reduce flow.

RESONANCE DSC
# 379
The device is being operated in the resonance frequency.
"
Caution!
If the device is operated in the resonance frequency, this
can result in damage which can lead to complete device
failure.
Reduce flow.
S
$
FLUIDTEMP. MIN
# 381
The limit value for the minimum fluid temperature
permitted is undershot.
Increase the fluid temperature.
S
$
FLUIDTEMP. MAX
# 382
The limit value for the maximum fluid temperature
permitted is overshot.
Reduce the fluid temperature.
S
$
DSC SENS DEFCT
# 394
The DSC sensor is defective, measurement no longer
takes place.
Contact your Endress+Hauser service organization.
S
!
DSC SENS LIMIT
# 395
The DSC sensor is being operated near application limits,
device failure is probable soon.
If this message is permanently displayed, contact your
Endress+Hauser service organization.
