The UI current loop jumpers are located on the circuit board under the controller cover near the UI terminals. When a UI is defined in the system software as a 4-20 mA Analog Input, set the UI's current loop jumper to the Enabled position as in Figure 1.

Figure 1. Current loop jumper positions

Setting the current loop jumper to the Enabled position connects an internal 100 ohms resistor across the UI terminals, which maintains the 4–20 mA current loop circuit even when power to the controller is interrupted or off.

Important: Current loop jumpers must be in the Disabled (default) position for all UIs that are not set up to operate as 4–20 mA analog inputs.
Important: A current loop jumper must be in the Enabled position to maintain a closed 4-20 mA current loop.

The following table identifies the current loop switches associated with each UI on the controller.
