M22 – ANALOG INPUTS (AINn, n=1...4)
P22.n.01 Input type
P22.n.02 Start scale value
P22.n.03 Multiplier
P22.n.04 End scale value
P22.n.05 Multiplier
P22.n.06 Description
P22.n.07 Unit of measure
Note: This menu is divided into 4 sections for the analog inputs AIN1...AIN4, available with the EXP1004 expansion modules.
P22.n.01 – Specifies the type of sensor connected to the analog input. The sensor should be connected to the appropriate terminal for the type selected. See
expansion module manual.
P22.n.02 – P22.n.03 – Define the value to display for a sensor signal at minimum, i.e. start scale range defined by the type (0mA, 4mA, 0V, -5V).
Note: These parameters are not used for a PT100 sensor type.
P22.n.04 – P22.n.05 – Define the value to display for a sensor signal at maximum, i.e. start scale range defined by the type (20mA, 10V, +5V).
Note: These parameters are not used for a type PT100 sensor.
P22.n.06 – Description of measurements associated with analog input. 16-character free text.
P22.n.07 – Unit of measure. 6-character free text. If the input is a type PT100 and the unit of measure is °F, the temperature will be displayed in degrees
Fahrenheit, otherwise it will be in degrees Celsius
Application example: The analog input AIN3 must read a 4...20mA signal from an electronic level sensor, that will be shown on the display with the descriprion
'Reserve fuel tank level', with a full scale of 1500 litres.
So, section 3 of this menu that is referred to AIN3 is programmed as follows:
P22.3.01 = 4...20mA
P22.3.02 = 0
P22.3.03 = x1
P22.3.04 = 1500
P22.3.05 = x1
P22.3.06 = Reserve tank level
P22.3.07 = Litres.
M23 – ANALOG OUTPUTS (AOUn, n=1...4)
P23.n.01 Output type
P23.n.02 Reference measurement
P23.n.03 Channel number x
P23.n.04 Start scale value
P23.n.05 Multiplier
P23.n.06 End scale value
P23.n.07 Multiplier
Note: This menu is divided into 4 sections for the analog outputs AOU1...AOU4 available when EXP1005 expansion module is used.
P23.n.01 – Specifies the type of output analog signal. The sensor should be connected to the appropriate terminal on the basis of the type selected. See
expansion module manual.
P23.n.02 – Measurement on which the analog output value depends.
P23.n.03 – The channel is defined when the reference measurement is an internal multichannel measurement (AINx for instance).
P23.n.04 – P23.n.05 – Define the measurement value that corresponds to start scale (minimum) range (0mA, 4mA, 0V, -5V).
P23.n.06 – P23.n.07 – Define the measurement value that corresponds to end scale (maximum) range (20mA, 10V, +5V).
Application example: The analog output AOU2 must emit a 0..20mA signal proportional to the total active power, from 0 to 500kW.
So, section 2 of this menu that is referred to AOU2 is programmed as follows.
P23.2.01 = 0...20mA
P23.2.02 = kW tot
P23.2.03 = 1 (not used)
P23.2.04 = 0
P23.2.05 = x1
P23.2.06 = 500
P23.2.07 = x1k.
