The current loop fail-safe jumpers are on the circuit board under the controller cover near the UI terminals. When a UI is defined in the system software as a 4 to 20 mA analog input and the UI’s current loop jumper is in the default disabled position, the 4 to 20 mA current loop circuit opens whenever power to the controller is interrupted or off. The following figure shows this setup

Figure 1. Current loop jumper positions

Setting the current loop jumper to the enabled position, as shown in Figure 1 connects an internal 100 ohm resistor across the UI terminals, which maintains the 4 to 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 to 20 mA analog inputs.

The following table identifies the current loop jumpers that are associated with each UI on the IOM5711 controller.
