PTC Input (Analog Input [T1] to [T4])
PTC 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 216
Analog input x
PTC ON
[x = 1 to 4]
PTC 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 217
Name and unit
----------------
PTC; description User defined text
The description of the analog input may be programmed using this parameter. A
maximum of four zeros may be used as placeholders for the numerical measured
values. Characters may divide the placeholders (i.e. a comma). The measured val-
ues subsequently appear wherever the zeros are placed. The measured values sub-
sequently appear wherever the zeros are placed.
Parameter 218
limit warning
value 000°C
PTC input; limit value for class F1 alarm 0 to 100 %
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 219
limit shutdown
value 000°C
PTC input; limit value for class F3 alarm 0 to 100 %
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 220
Delay
limit 1/2 000s
PTC 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 221
Monitoring for
----------------
PTC 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.
