Error diagnosis

7.3 Error diagnosis
When an error occurs, a 5-digit error code is shown on the display "STATUS.NUMBER" (e. g. C0010). The
LED on the RESET pushbutton lights up.
A 4-digit error number appears on the display of the Teaching Box. The first character of the error
number is not shown. For example the display shows "0010" for "C0010" and plain text.
A list of the messages that have previously occurred can be called up in the monitor menu of the
"ERROR LOG" of the Teaching Box. The error must first be reset for this.
The error numbers, the errors causes and the countermeasures are listed in the operating and pro-
gramming instructions. If an error can not be remedied by the countermeasures listed then please
contact your sales partner.
