5 .8 Error indication at operation
The red error indication LED indicates the exceedance of operation limit values, faulty inputs or also
device errors.
The information, what reason has led to an error indication can be found in each of the two function
menus in the area extended functions of the menu point service.
Only the last detected error is displayed.
The error information in the service menu is not stored in the case of a voltage fail.
At every restart of the device the system is completely tested concerning the parameters and settings.
LED
error indication
in service menu description / remedy
red
yellow – flashing
no
Short circuit at the switch output, whose yellow switch condition LED is flashing.
Check the load at the respective switch output.
red
brch
The internal self-supervision has detected a wire break of the sensor element Pt100.
If the error cannot be removed after repeated restart of the device by short voltage interrupts,
there can be an irreversible device defect.
By using the redundancy function it can be switched to the second sensor.
red
Hur
The internal self-supervision has detected a short circuit of the sensor element Pt100.
If the error cannot be removed after repeated restart of the device by short voltage interrupts,
there can be an irreversible device defect.
By using the redundancy function it can be switched to the second sensor.
red
FLAS
An error in the internal nonvolatile data memory (flash) has been detected.
If the error cannot be removed after repeated restart of the device by short voltage interrupts,
there can be an irreversible device defect.
red – flashing
Nunt
The lower measuring range limit value has been underrun.
Check the system temperature of your plant.
This temperature may be lower than the measuring range zero value.
red – flashing
NuEb
The upper measuring range limit value has been exceeded.
Check the system temperature of your plant.
This temperature may be higher than the measuring range end value.
red – flashing
Aunt
The lower limit value of the current output (3,9mA) has been underrun.
Check the adjustment of the current output. The system temperature is lower than the
temperature concerning to the current output at 3,9mA.
red – flashing
AuEb
The upper limit value of the current output (21mA) has been exceeded.
Check the adjustment of the current output. The system temperature is higher than the
temperature concerning to the current output at 21mA.
red – flashing
S1oG
The switch back point rSP1 of the switch output 1 has been adjusted higher or equal to the
switch point SP_1.
Check the adjustment of the switch output 1
red – flashing
S2oG
The switch back point rSP2 of the switch output 2 has been adjusted higher or equal to the
switch point SP_2.
Check the adjustment of the switch output 2
red – flashing
S1oP
An error has been detected at switch output 1.
Detach the output load of the switch output 1. If the error cannot be removed after repeated
restart of the device by short voltage interrupts, there can be an irreversible device defect.
red – flashing
S2oP
An error has been detected at switch output 2.
Detach the output load of the switch output 2. If the error cannot be removed after repeated
restart of the device by short voltage interrupts, there can be an irreversible device defect.
red – flashing
rAN
An error in the internal working memory (RAM) has been detected.
If the error cannot be removed after repeated restart of the device by short voltage interrupts,
there can be an irreversible device defect.
red – flashing
drFt
The transgression of the set drift threshold value has been detected.
Increase the drift threshold value or the drift delay time.
Replace, if necessary, the temperature switch.
EEEE
Display while
operation
Wrong password entered – Acknowledgment by control key „Set“
Measuring range adjusted to ≤25% of the nominal range – Readjustment necessary
Maximum display value of 9999 has been exceeded – Readjustment necessary
-EEE
Display while
operation
Minimum display value of -999 has been underrun – Readjustment necessary
