If an error occurs, operating mode «A» and error display «E» light up alternately and an error code such as E 012 is displayed. The LED changes to
flashing red, the 4 most recent errors are stored and can be interrogated.

Briefly pressing the «Data» button shows the last of 4 errors on the display. Another short press switches to the error before that, and so on. When
the button is pressed for the 5th time, the device switches back to automatic mode. If you press the «Data» button for 4 seconds during the query,
all error messages are deleted. The figure shows memory slot 1 in which error 001, Interruption loop 1, has been stored (example).
