Field Communicator Setup & Diag > Detailed Setup > Transmitter/Switches (1-2-9)
Note
These menu items are only available on units that have the optional position transmitter / limit switch hardware installed.
If optional limit switches are being used, power must be applied to the switch circuits throughout the calibration routine. Failure to
power the switches may result in incorrect switch orientation.
Follow the prompts on the Field Communicator display to configure the following:
D Switch 1 Trip Point—Defines the threshold for the limit switch wired to terminals +41 and -42 in percent of calibrated
travel.
D Switch 1 Closed—Configures the action of the limit switch wired to terminals +41 and -42. Selecting ABOVE
configures the switch to be closed when the travel is above the trip point. Selecting BELOW configures the switch to
be closed when the travel is below the trip point. Selecting DISABLED removes the icons and status from the display.
D Switch 2 Trip Point—Defines the threshold for the limit switch wired to terminals +51 and -52 in percent of calibrated
travel.
D Switch 2 Closed—Configures the action of the limit switch wired to terminals +51 and -52. Selecting ABOVE travel is
above the trip point. Selecting BELOW configures the switch to be closed when the travel is below the trip point.
Selecting DISABLED removes the icons and status from the display.
Note
Switch #2 is only operational if power is applied to switch #1 also. Switch #2 cannot be used alone.
D Transmitter Action—This configures the relationship between the valve travel and the position transmitter output
signal. If you select CLOSED, the transmitter will send 4 mA when the valve is closed. If you select OPEN, the
transmitter will send 4 mA when the valve is open.
A switch is located on the options board to select the transmitter fail signal (high+ or low-). High+ will result in a
current output of > 22.5 mA upon transmitter failure. Low- will result in a current output of < 3.6 mA. Refer to
figure 2‐6 for location and switch selection.
