Error indication (short reference)
A detected error is indicated on the display by means of blocking or error messages. A distinction should be made between these two messages due to the fact that bloc- king can be of a temporary nature, however, error messages are fixed lockings. The control will try its utmost to prevent locking and will temporarily switch off the unit by blocking it. Hereunder is a list of some messages.
