3.7. Analog inputs
3.7.1. Functional diagram of analog inputs
The Advanced Power Controller has 3 analog inputs whose main purpose is to control the power output. The input electri-
cal signal is processed to obtain a valid analog value for the control function.
The diagram shows the signal processing sequences.

The parameter sets the type of electrical signal expected on analog input A1 or A2 or A3. This signal is typically generated by a probe.
Options : 0 = Input disabled
1
= Voltage 0...10 V
2 = Voltage 0...5 V or potentiometer
3 = Current 0...20 mA
4 = Current 4...20 mA

The parameter sets the lower limit of the measurement scale used for analog input A1 or A2 or A3.
For examples of the use of the parameter, see paragraph “4.1. Setting parameters LS.A1/LS.A2/LS.A3 and HS.A1/HS.A2/HS.A3”.
