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.
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

Function:
Terminal X42/5 can be programmed as an analog input accepting a voltage or input from either Pt
1000 (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
