8.2 Analog inputs
Analog inputs can be activated as described in section 8.1.1 "Activate function".
With the analog inputs, the following settings are available:
Type, measuring range and readjustment.
8.2.1 Type
If the unit is °C, the type can be selected. If the unit is not °C, the type is always
0...10 V.
The following types are available:
 LG-Ni1000
 2xLG-Ni1000

8.2.2 Measuring range
Passive temperature signals from LG-Ni 1000 sensing elements have a measuring
range of 50…250 °C.
Passive temperature signals from 2x LG-Ni 1000 or T1 sensing elements have a
measuring range of 50...150 °C.
Passive temperature signals from Pt1000 sensing elements have a measuring
range of 50...+ 400 °C.
With active signals, the measuring range is definable. A lower and an upper
measured value must be entered.
