Resetting the Application Memory

onn!! This procedure should only be carried out by qualified system integrators since the current
application will stop running and the controller will return to its factory application.
To reset the processor’s program memory (application programs) the controller has to be connected to the
power supply. Use the reset button accessed through the small opening located to the right of the PORT 3
connector. Preferably use a non-metallic object when pressing the reset button since a metallic object could
potentially short/damage the electronics next to the button if it slips of the button.
A recommendation is to use a wooden toothpick to access the reset button.
If the controller is not possible to reset in this way for some reason it should be powered down. Then keep
the reset button pressed in while reconnecting the power.
