If you enabled the Trex unit to power a device, the Trex unit stops providing power when you close the Loop Diagnostics. If the Trex unit was powering a positioner, the application prompts you to select a current value for the positioner before the application closes. This allows you to move the positioner to a safe position. After the selected current value is reached, the Trex unit stops providing power.
