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.
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
(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 ).

26-02 Terminal X42/5 Mode
Option: 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
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

3.24.3 26-1* Analog Input X42/1
Parameters for configuring the scaling and limits for analog input, terminal X42/1.
26-10 Terminal X42/1 Low Voltage
Range: Function:
0.07 V* [Application dependant] Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value set in par. 26-14
Term. X42/1 Low Ref./Feedb. Value .
26-11 Terminal X42/1 High Voltage
Range: Function:
10.00 V* [Application dependant] Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par. 26-15
Term. X42/1 High Ref./Feedb. Value .
26-14 Term. X42/1 Low Ref./Feedb. Value
Range: Function:
0.000 N/A* [-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the low voltage value set in
par. 26-10
Terminal X42/1 Low Voltage .
