4400 Transmitter
October 2023
3. Install the mounting bracket on the actuator,
4. Attach the position transmitter to the mounting bracket using the four mounting bolts.
5. Check for clearance between the magnet assembly and the positioner feedback slot.
6. Once the instrument is mounted, perform the local interface calibration procedure, as described in the Calibrating
the LUI section.
7. Verify that the magnet assembly remains centered throughout the entire rotating range.
Electrical Connections
Position Transmitter or Discrete Switch
The position transmitter circuit derives its operating power from the control system input channel in the same manner
as a two-wire system.
The discrete switch is a solid state circuit (1 amp maximum) which opens and closes based on a user configurable trip
point. The trip point can be based on valve travel anywhere within the calibrated travel range. In order for the switch
output to function, the position transmitter must be powered. If power is lost, the switch will always go to the open
state. The output circuit, whether operating as a transmitter or switch, is galvanically isolated from the position
control loop circuit such that different ground references between the two circuits are allowed.
Follow the steps below to connect field wiring to the 4400 transmitter.
WARNING
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection, and
temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
To avoid personal injury resulting from electrical shock, do not exceed maximum input voltage specified on the product
nameplate. If the input voltage specified differs, do not exceed the lowest specified maximum input voltage.
Personal injury or property damage caused by fire or explosion may occur if electrical connections are attempted in a
potentially explosive atmosphere or in an area that has been classified as hazardous. Confirm that area classification and
atmosphere conditions permit the safe removal of the terminal box cover before proceeding.
