Parameter 217
Analog input x
0-00mA
[x = 1 to 3]
0/4 to 20 mA input; measuring range 0 to 20 mA / 4 to 20mA
The measuring range 0 to 20 mA or 4 to 20 mA is selected via this parameter. If 4
to 20 mA is configured and a current of less than 2 mA is measured, the controller
assumes a wire break has occurred (see below).
Parameter 218
Value at
0% 0000
0/4 to 20 mA input; smallest input value -9,999 to 9,999
The user must assign a numeric value to the scaleable analog input that corresponds
to the smallest input value  Definition of the lower value (i.e. 0 % equals 0 kW,
0 V, etc.) at the minimum analog input value of 0 mA or 4 mA.
Parameter 219
Value at
100% 0000
0/4 to 20 mA input; largest input value -9,999 to 9,999
The user must assign a numeric value to the scaleable analog input that corresponds
to the largest input value  Definition of the upper value (i.e. 100 % equals
500 kW, 400 V, etc.) at the maximum analog input value of 20 mA.
Parameter 220
Limit warning
value -0000
0/4 to 20 mA input; limit value for class F1 alarm -9,999 to 9,999
If the measured value exceeds or falls below this configured threshold value (de-
pendent upon Parameter 223) for at least the delay time (Parameter 222), the fol-
lo
wing alarm class is initiated.
Issuing of F1 class alarm
Parameter 221
Limit shutdown
value -0000
0/4 to 20 mA input; limit value for class F3 alarm -9,999 to 9,999
If the measured value exceeds or falls below this configured threshold value (de-
pendent upon Parameter 223) for at least the delay time (Parameter 222), the fol-
lo
wing alarm class is initiated.
Issuing of F3 class alarm
Parameter 222
Delay
limit 1/2 000s
0/4 to 20 mA input; delay time for limit values of class F1 and F3 alarm 0 to 650 s
In order to initiate an alarm, the measured value must be over or under (dependent
upon Parameter 223) the configured threshold value (Parameter 220 or Para-
m
eter 221) without interruption for at least this time.
Parameter 223
Monitoring for
----------------
0/4 to 20 mA 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 220 or Parameter 221).
hig
h limit mon.: The measured value must exceed the threshold value.
low limit mon.: The measured value must fall below the threshold value.
