Parameters
P255 mA Input Function
Assigns the mA input function for the input selected, inputs 1 to 2 (P250 - 01 to – 02)
entry:
0 = off
f
1 = PID setpoint
2 = PID process variable
P261 4 mA Input Trim
Trims the 4 mA input level for the input selected, inputs 1 to 2 (P250 - 01 to – 02).
The trim adjusts the input to agree with an external 4 mA source.
Follow the BW500 on line instructions to trim the input
P262 20 mA Input Trim
Trims the 20 mA input level for the input selected, inputs 1 to 2 (P250 - 01 to – 02).
The trim adjust the input to agree with an external 20 mA source.
Follow the BW500 on line instructions to trim the input
P270 Auxiliary Input Function
Selects the auxiliary input function for the input selected; inputs 1 to 5 (P270 - 01 to –
13).
