•
A bus voltage failure will not terminate an active manual control even if the “Manual control in case
of bus voltage failure = disabled” parameter has been set. It will be disabled only after ending manual
control.
•
Other parameters and communication objects of the manual control are visible only with the
configuration: "Manual control during bus mode = enabled". For this reason the disable function, the
status message and the disabling of the bus mode can only be configured with the above parameter
setting in place.
Setting the behaviour for the beginning and for the end of manual control
The manual control features a temporary and permanent manual control mode. These modes cause
different behaviours, especially at the end of the control mode. Basically, it should be noted that the
bus, i.e. control of the DALI groups by direct control (switching / dimming / brightness value / scene /
central) or by the disable or forced-position functions is always disabled in case of an active manual
control mode. This is to say that the manual control mode has the highest priority.
Behaviour at the beginning of the manual control:
There is no difference in the behaviour between temporary or permanent manual control at the
beginning of the manual control. When activating the manual control, the brightness states of the DALI
groups do not change. Blinking during disable function: The blinking of the disable function will be
discontinued at the beginning of the manual control. The brightness remains set to the blinking state
adjusted last ("ON" or "OFF"). The switching status is indicated by “ON”.
Manual control can override active forced-control positions or disable functions. These functions are
reactivated after the manual control mode has been deactivated unless they have been cancelled in
the meantime.
Behaviour at the end of the manual control mode:
The behaviour at the end of manual control differs between the temporary and permanent manual
control.
The temporary manual control mode is shut off automatically when the last group has been addressed
and when the select key is pressed once more. When the temporary manual control mode is shut
off, the Gateway returns to 'normal' bus mode and does not change the brightness states selected by
manual control. If, however, a forced-control position or a disable function has been activated via the
bus prior to or during manual control, the actuator re-executes these higher-priority functions for the
relevant groups.
The permanent manual control mode is shut off, when the select key is pressed for more than 5 s.
Depending on the ETS parameterization of the Gateway, the groups will be set to the state last
adjusted in the manual control mode or set to the state internally tracked (direct operation, forced-
control position, disable lock) when the permanent manual control is shut off. The "Behaviour at the
end of permanent manual control during bus mode" parameter defines the corresponding reaction.
Set the "Behaviour at the end of permanent manual control during bus mode" parameter to "No
change".
All telegrams received during an active permanent manual control for direct operation (switching,
dimming, brightness value, central, scenes) will be discarded. After the end of the permanent manual
control, the current state of all brightness states remains unchanged. If, however, a forced-control
position or a disable function has been activated via the bus prior to or during manual control, the
Gateway re-executes these higher-priority functions for the relevant groups.
