Menu → Measurement → Reset.
Press theESC key, several times if necessary, to return to the default display.
Clear the LEDs on the front panel by pressing the LED key, so that they only show real events and states. In
this context, saved output relays are reset, too. Pressing the LED key also serves as a test for the LEDs on the
front panel because they should all light when the button is pressed. If the LEDs display states relevant by that
moment, these LEDs, of course, stay lit.
The green "RUN" LED must light up, whereas the red "ERROR" must not light up.
Close the protective switches. If test switches are available, then these must be in the operating position.
The device is now ready for operation.
