Reset button
The reset button is located behind the service access window.
To remove this, place a coin in the intended slot and turn counterclockwise until the orange and blue markings in
the following image overlap. Tilt the coin to remove the cover.
To secure the service access window again, connect it to the X90 mobile system again and turn it clockwise with
a coin until the markings on the cover point to the markings on the housing.
The button must be pressed for less than 2 seconds to trigger a reset. This triggers a hardware reset on the CPU,
which means that:
•
All application programs are stopped.
•
All outputs are set to zero.
The controller then boots into service mode by default. The boot mode that follows after pressing the reset button
can be defined in Automation Studio.
•
Service mode (default)
