6.6.1 Additional error messages in case of assembly mounting
With assembly mounting, each of the two devices basically show exactly the same
errors as with single mounting, e.g. in the event of a mains failure the error message
“UNDERVOLTAGE” is shown on both displays - possibly slightly diff erent in terms of time
- before the display fi nally goes out.
Furthermore, the following special features apply:
• CONNECTION ERROR: If the communication cable has not been correctly
connected, each controller will react like a single device. No error message is
displayed. A communication error can be recognised by the fact that the ON/OFF
AUTOMATIC LED does not fl ash on the secondary device.
When assembly mounting has been correctly confi gured, the ON/OFF AUTOMATIC
LED of the relevant MASTER must be illuminating permanently and the LED of the
respective SLAVE must be fl ashing
