Pt100 Input (Analog Input [T1] to [T4])
Pt100 inputs may be measured here. The analog input is displayed with its description. Two threshold limits can
be monitored. The first level initiates a class F1 alarm, the second level initiates a class F3 alarm.
Parameter 204
Temperature x
Pt100 ON
[x = 1 to 4]
Pt100 input; enable/disable ON/OFF
ON................The value of this input appears in the display, and monitoring is en-
abled. The subsequent parameters of this function are displayed.
OFF..............No display or monitoring is performed, and the subsequent parame-
ters of this function are not displayed.
Parameter 205
***name****
-----------000°C
Pt100 input; description User defined text
The description of the analog input may be programmed using this parameter. A
maximum of eleven characters may be used to describe the measured value. In the
event of an alarm, the description and the monitored value are displayed with an
exclamation mark before the temperature.
Parameter 206
limit
warning 000°C
Pt100 input; limit value for class F1 alarm 0 to 225 °C / 0 to 437 °F
If the measured value exceeds or falls below this configured threshold value (de-
pendent upon
Parameter 209) for at least the delay time (Parameter 208), the fol-
lowing alarm class is initiated.
Issuing of class F1 alarm
Parameter 207
limit
shutdown 000°C
Pt100 input; limit value for class F3 alarm 0 to 225 °C / 0 to 437 °F
If the measured value exceeds or falls below this configured threshold value (de-
pendent upon
Parameter 209) for at least the delay time (Parameter 208), the fol-
lowing alarm class is initiated.
Issuing of class F3 alarm
Parameter 208
Delay
limit 1/2 000s
Pt100 input; delay time for limit values of class F1 and F3 alarm 0 to 999 s
In order to initiate an alarm, the measured value (Parameter 206 or Parameter 207)
must be over or under the configured threshold value (dependent upon
Para-
meter 209) without interruption for at least this time.
Parameter 209
Monitoring for
----------------
Pt100 input; monitoring for ... high limit mon. / low limit mon.
A fault condition is recognized when the measured value has exceeded or fallen be-
low the threshold value (
Parameter 206 or Parameter 207).
high limit mon.: The measured value must exceed the threshold value.
low limit mon.: The measured value must fall below the threshold value.
NOTE
If temperature limit monitoring is not required, a threshold value, which is higher than the expected
temperature must be configured to the corresponding parameter (e.g. the ambient temperature is
100 °C).
