Parameter 226
Delay
limit 1/2 000s
VDO input, temperature; delay for limit values of class F1 and F3 alarm 0 to 999 s
In order to initiate an alarm, the measured value must be over or under (dependent
upon
Parameter 227) the threshold value (Parameter 224 or Parameter 225) without
interruption for at least this time.
Parameter 227
Monitoring for
----------------
VDO input, temperature; 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 224 or Parameter 225).
high limit mon.: The measured value must exceed threshold value.
low limit mon.: The measured value must fall below the threshold value.
VDO Input 'Pressure' (Analog Input [T1 to T4])
VDO inputs for pressure may be measured here. The analog input is displayed with its description. Two thresh-
old levels can be monitored. The first level initiates a class F1 alarm, the second level initiates a class F3 alarm.
Parameter 228
Analog input x
VDO ON
[x = 1 to 4]
VDO input, pressure; 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 229
Name and unit
----------------
VDO input, pressure; 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 value will
always be displayed and transmitted via the interface in bar [× 0.1] or psi [× 0.1].
Parameter 230
Pressure in
bar
optional
VDO input, pressure; unit selection bar/psi
The unit of measurement for the analog input may be changed from "bar" to "psi".
The conversion factor is as follows: 1 psi = 14.5 bar.
bar................The measuring values are monitored and indicated in bar.
psi.................The measuring values are monitored and indicated in psi.
Measurement Unit [bar] (optional)
Parameter 231
Analog input x
VDO 0-00bar
[x = 1 to 4]
VDO input, pressure; measuring range 0 to 5 / 0 to 10 bar
The measuring range of the analog input can be selected.
0 to 5 bar......Measuring range 0 to 180 Ohm
0 to 10 bar....Measuring range 0 to 180 Ohm
Parameter 232
Limit warning
value 00.0bar
VDO input, pressure; limit value for class F1 alarm 0.0 to 10.0 bar
If the measured value exceeds or falls below this configured threshold value (de-
pendent upon
Parameter 238) for at least the delay time (Parameter 237), the fol-
lowing alarm class is initiated.
