How do I set up the analogue input of the MM420 as a 4-20mA current loop?
Example using a 300Ohm resistor:
The following parameters need to be set to configure the analogue input scaling:
P0757 (Value X1) = (4mA x 300Ohm) = 1.2V
P0759 (Value X2) = (20mA x 300Ohm) = 6.0V
P0761 (Width of deadband) = 1.2V
The above example uses a 300Ohm resistor, so if a different resistor is being used, the corresponding values for P0757-P0761 must be calculated.
