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 feedback, the unit must be set for either Celsius or Fahrenheit
(par.20-12
Reference/Feedback Unit , par.21-10 Ext. 1 Ref./Feedback Unit , par.21-30 Ext. 2 Ref./
Feedback Unit
or par.21-50 Ext. 3 Ref./Feedback Unit ).
