In addition, the entire status information of the device and the maximum indicators of the two
sen.sor values and the internal temperature are available.

(MODE_BLK)
Description
Corrosion
detec-tion
(CORROSION_
DETECTION)
AUTO - OOS
OFF: Corrosion detection off
ON
: Corrosion detection on
Note:
Only possible for RTD 4-wire connection and
thermocouples (TC).
Sensor drift
mon-itoring
(SENSOR_DRIFT_
MONITORING)
AUTO - OOS
Deviation between SV1 and SV2 as error (Failure) or
as need for mainte-nance (Maintenance):
OFF: Sensor deviation monitoring off
FAILURE: (sensor deviation > SENSOR_
DRIFT_LIMIT) => Failure
MAINTENANCE: (sensor deviation >
SENSOR_DRIFT_LIMIT) => Maintenance
Sensor drift mode
(SENSOR_DRIFT_
MODE)
AUTO - OOS
Select whether a status is generated if the value set in
the SENSOR_DRIFT_LIMIT parameter is undershot
(Undershooting) or over-shot (Overshooting).
Note:
If “Overshooting” is selected, the corresponding
status is generated if the limit value is overshot
(SENSOR_DRIFT_LIMIT). In the case of
“Under-shooting”, the status is output if the
limit value is undershot.
Sensor Drift alert
value (SENSOR_
DRIFT_ALERT_
VALUE)
AUTO - OOS
Limit value of the permitted deviation from 1 to
999.99.
System alarm
delay (SYSTEM_
ALARM_DELAY)
AUTO - OOS
Alarm hysteresis: Value as to the time a device status
(Failure or Mainte-nance) and measured value status
(Bad or Uncertain) is delayed until the status is
output. Can be configured between 0 and 10 seconds
Note:
This setting does not affect the display.
Ambient temp.
alarm (AMBIENT_
ALARM)
AUTO - OOS
Maintenance or Failure in the event of the operating
temperature of the transmitter being undershot or
overshot (< -40 °C (-40 °F) or > +85 °C (185 °F)):
Maintenance: Int. temperature overshoot/
undershoot results in mes-sage.
Failure: Int. temperature overshoot/undershoot
results in 'Failure' device status.
