If, at present, the fault status message from a non-listed bus user is the most severe
pending, it will

.
The fault LED will not be lit. Acknowledgement and reset with the fault button is not
possible and must be made locally on the respective device.
10.3 Acknowledgement of faults
When pressing the flashing fault button, all faults to be acknowledged will be acknowl-
edged. Only faults of devices from the device list will be acknowledged. Acknowledge-
ment can take place from any of the menus.
•
When a device list is full, acknowledgement of faults can take up to 1 minute
•
Faults of Synco™ devices not contained on the device list cannot be acknowledged
10.4 Resetting faults
Only faults of devices from the device list can be reset. In contrast to fault acknowl-
edgements, faults must be reset on an individual basis. A reset is made by pressing the
illuminated fault button.
To ensure that the fault and the reset command can be unambiguously assigned,
resetting of the current or the displayed fault can only take place on the following me-
nus:
•

•
On menu
