CAUTION
  • Risk of Electric Shock:
  • Disconnect supply power to the expansion module before attempting to adjust the UI current loop jumpers. Failure to disconnect the supply power may result in electric shock.
ATTENTION
  • Mise En Garde: Risque de décharge électrique:
  • Débrancher l'alimentation de l'controller avant tout réglage du UI current loop jumpers. Le non-respect de cette précaution risque de provoquer une décharge électrique.

The UI current loop jumpers are on the circuit board under the expansion module cover near the UI terminals (Figure 1). 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 (Figure 1).

Figure 1. UI Current loop jumper positions

Setting the current loop jumper to the Enabled position, connects an internal 100 ohm resistor across the UI terminals, which maintains the 4-20 mA current loop circuit even when power to the expansion module 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 tables identify the current loop switches associated with each UI on the XPM09090 and XPM04060 models.
