Abstract
This disclosure concerns a medical device designed for delivering a medical fluid or designed for controlling delivery of a medical fluid, and to a method of operating such a medical device. The medical device comprises a user interface associated with an electronic circuit connected to a first port and to a second port of a controller. The electronic circuit enables the controller to detect actuation of the user interface. The controller is configured to execute the following sequence of steps: first step: configure the first port as an output port and to apply a first signal to the first port; second step: to acquire a second signal from the second port; and third step: to determine on the basis of the second signal if a short circuit has occurred and to generate a short circuit alert signal if applicable.
