Scaleable analog input 0/4 to 20 mA (analog input [T1] - [T3])
NOTE
The scalable analog inputs 0/4 to 20 mA can be configured alternatively for the following functions:
• Mains interchange (import/export) real power actual value (Parameter 24)
• Real p
ower set point value (Parameter 78)
If one of the both functions is assigned to an av
ailable 0/4 to 20 mA input T{x} (refer to Parameter 24
a
nd Parameter 78), that analog input T{x} must be c
onfigured to OFF. The analog input can no longer
be used as an alarm input.
Priority of the analog input functions
The following priority is valid if more than one function has been assigned to a analog input:
• Highest priority: Mains interchange (import/export) real power actual value measurement
• Middle priority: Real power set point value
• Lowest priority: Measuring input as common analog value
0/4 to 20 mA sensors may be measured here. A description and the engineering unit may be assigned to the in-
put. The analog input is displayed with its description. Two limit levels can be monitored. The first limit level in-
itiates a class F1 alarm, the second limit level initiates a class F3 alarm.
Parameter 215
Analog input x
scalable ON
[x = 1 to 3]
0/4 to 20 mA input; enable/disable ON/OFF
ON ................ The value of this input appears in the display and monitoring is
enabled. The subsequent parameters of this function are displayed.
OFF .............. The value of this input does not appear in the display and monitoring
is disabled. The subsequent parameters of this function are not dis-
played.
NOTE
If the unit is equipped with a second communication interface (Option SB03 and Option SC10), this
parameter can only be configured via LeoPC1.
Parameter 216
Name and unit
----------------
0/4 to 20 mA input; 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 measuring
values. Characters may divide the placeholders (i.e. a comma). The measured val-
ues subsequently appear wherever the zeros are placed.
