3.24.1 26-0* Analog I/O Mode
Parameter group for setting up the analog I/O configu-
ration. The option is equipped with 3 analog inputs. These
analog inputs can be freely allocated to either voltage (0V
- +10V), Pt 1000 or Ni 1000 temperature sensor input.
26-00 Terminal X42/1 Mode
Option: Function:
Terminal X42/1 can be programmed as an
analog input accepting a voltage or input
from either Pt1000 (1000
Ω
at 0
°
C) or Ni 1000
(1000
Ω
at 0
°
C) temperature sensors. Select
the desired mode.
Pt 1000 , [2] and Ni 1000 [4] if operating in
Celsius - Pt 1000 [3] and Ni 1000 [5] if
operating in Fahrenheit.
Notice: If the input is not in use, it must be
set for Voltage!
If set for temperature and used as feed back,
the unit must be set for either Celsius or
Fahrenheit (
20-12 Reference/Feedback Unit ,
21-10 Ext. 1 Ref./Feedback Unit , 21-30 Ext. 2
Ref./Feedback Unit or 21-50 Ext. 3 Ref./Feedback
Unit ).

26-01 Terminal X42/3 Mode
Option: Function:
Terminal X42/3 can be programmed as an
analog input accepting a voltage or input
from either Pt 1000 or Ni 1000 temperature
sensors. Select the desired mode.
Pt 1000, [2] and Ni 1000, [4] if operating in
Celsius - Pt 1000, [3] and Ni 1000, [5] if
operating in Fahrenheit.
