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, or
• real power set point value.
If one of the both functions is assigned to an available 0/4 to 20 mA input T{x} (see Parameter 34 and
Parameter 91), the corresponding 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 an engineering unit may be assigned to the input.
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 243
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 .............. No display or monitoring is performed, and the subsequent parame-
ters of this function are not displayed.
NOTE
If the unit is equipped with a second interface (Y1-Y5), this parameter can only be configured via
LeoPC1.
Parameter 244
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.
