Note: this menu is divided into 8 sections for the analog inputs AIN1…AIN8, available in combination with the expansion modules EXP1004.
P19.n.01
- This specifies the sensor type connected to the analog input. According to the selected type, the sensor must be connected to the appropriate terminal.
See the input module manual.
P19.n.02 and P19.n.03
- These define the value to be viewed when the sensor signal is low, i.e. at the beginning of the range defined by the type (0mA, 4mA, 0V, -
5V etc). Note: these parameters are not used for PT100 type sensors.
P19.n.04 and P19.n.05
These define the value to be viewed when the sensor signal is maximum, i.e. at the full scale of the range defined by the type (20ma,10V,
+5V etc). These parameters are not used for PT100 type sensors.
P19.n.06
- Description of the measurement related to the analog input. Free text 16 characters.
P19.n.07
- Unit of measurement. Free text 6 characters. If the input is PT100 type and text of the unit of measurement is
°F
, the temperature will be displayed in
degrees Fahrenheit, otherwise it will be in degrees Celsius.
Example of application:The analog input AIN3 must reach a 4…20mA signal from an electronic level sensor which must be indicated on the display with the
message 'Tank reserve level’, and a full scale of 1500 litres.
Section 3 of this menu, referred to AIN3 will be programmed as follows.
P19.3.01 = 4…20mA
P19.3.02 = 0
(0 x 1 = 0 litres, scale start value corresponding to 4mA)
P19.3.03 = x1
P19.3.04 = 1500
(1500 x 1 = 1500 litres, full scale value corresponding to 20mA)
P19.3.05 = x1
P19.3.06 = 'Tank reserve level’
P19.3.07 = ‘litres’

Note: this menu is divided into 8 sections for the analog outputs AOU1…AOU8, available in combination with the expansion modules EXP1005.
P20.n.01
-
This specifies the analog output signal type. According to the selected type, the connection must be made on the appropriate terminal. See the analog
output module manual.
P20.n.02
- Measurement from which the anlogue output value depends.
P20.n.03
- Number of the source line SRCx to which the measurement selected in the previous parameter refers (if applicable).
P20.n.05
and
P20.n.06
- These define the value of the measurement which corresponds to an output value at the low end of the range (0mA, 4mA, 0V, -5V etc).
P20.n.07
and
P20.n.08
- These define the value of the measurement which corresponds to the top end of the range (20ma,10V, +5V etc).
Example of application: Analog output AOU2 must emit a 0..20mA signal proportional to the total active power of the SRC2 line, from 0 to 500 kW. Section 2 of this
menu, referred to AOU2 will be programmed as follows.
P20.2.01 = 0…20mA
P20.2.02 = kW tot
P20.2.03 = SRC2
P20.2.04 = 1 (not used)
P20.2.05 = 0
(0 x 1 = 0 W, start scale value)
P20.2.06 = x1
P20.2.07 = 500
(500 x 1 = 500 kW, full scale value)
P20.2.08 = x1k
