3. Apply a 100% signal to the actuator with the resistor in place and calibrate the analog input to 100% through the
configuration software or by sending a value of 1 to register 40005.
4. Apply a 0% signal to the actuator with the resistor in place and calibrate the analog input to 0% through the
configuration software or by sending a value of 1 to register 40004.
The result of not following these installation instructions could result in permanent damage to the analog input
circuitry. This damage can result in the inability of the controller to see the c ontrol signal, resulting in the actuator
moving the valve plug to the loss of signal position.
This configuration works by providing the 420mA signal a path to follow through the resistor whether primary power
to the actuator is on or off, which prevents the voltage on the analog input terminals from rising high enough to
damage the circuitry.
Note
Do not configure the actuator to 4-20 mA with the external resistor in place, as improper operation will result.
WARNING
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Process Management should
not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
