Current output 4 to 20 mA / voltage output 0 to 10 V
Failsafe mode The breakdown information displayed in the event of a breach of the measuring range
(over-range/under-range) can be configured in the
Analog output settings
parameters:
• Failure value for measured variable if the "0 V/2 mA exceeding limits" option is
selected:2 mA or 0 V
• Limit value for measured variable if the "Min/Max exceeding limits" option is
selected: 4 to 20 mA or 0 to 10 V
The breakdown information displayed in the event of a breach of the calibration range
(over-range/under-range) can be configured in the
Display filter parameter:
• Failure value for measured variable if the "Calibration range" option is selected:
2 mA or 0 V
• If the measuring device exceeds or drops below the temperature calibration range, a
failure value is also displayed for the concentration measured variable if it is active.
The breakdown information displayed if the process is not stationary (stationarity) can
be configured in the
Display filter parameter:
Failure value for the concentration measured variable if the "Enable stationarity"
option is selected : 2 mA or 0 V
The breakdown information to be displayed if the rate of change exceeds the limit
value can be configured in the
Change in [measured variable] parameter. If the
function is enabled:
Failure value for the
concentration measured variable: 2 mA or 0 V
In the event of interference influences (dispersion) above the limit value:
Failure value for the
concentration measured variable: 2 mA or 0 V
If there is not enough liquid or the sensor is defective:
Failure value for all measured variables: 2 mA or 0 V
Relay output
Failsafe mode If the temperature measurement range is exceeded or undershot:
For the
concentration measured variable: the current status is held.
If the temperature calibration range is exceeded or undershot:
For the
concentration measured variable: the current status is held.
The breakdown information to be displayed if the process is not stationary
(stationarity) can be configured in the
Display filter parameter. If the "Enable
stationarity" option is selected:
For the
concentration measured variable: the current status is held.
The breakdown information to be displayed if the rate of change exceeds the limit
value can be configured in the
Change in [measured variable] parameter. If the
function is enabled:
For the
concentration measured variable: the current status is held.
In the event of interference influences (dispersion) above the limit value:
For the
concentration measured variable: the current status is held.
If there is not enough fluid:
Measured value for all measured variables with the exception of temperature: 0 Switch
status as per the setting for the switching threshold or switch point ("Operating
Instructions" document, "Configuring the switch output" section).
If there is a sensor defect:
Measured value for all measured variables: 0 Switch status as per the setting for the
switching threshold or switch point ("Operating Instructions" document, "Configuring
the switch output" section).
Local display (transmitter with touch screen)
Color coding Color field signalizes measuring and device errors ("Operating Instructions" document,
"Diagnostics information on local display and in operating tool" section)
