4.3.9 Master-Slave-Operation
The following is a short description of the settings. For more details, there is a suggested solution on
our website
https://www.mdt.de/EN_Downloads_Solutions.html
under „Presence/Motion Detector“.
4.3.9.1 Light channels
In larger rooms, the use of a single motion detector is often not sufficient. To detect motion in every
corner of the room, several detectors must be used throughout the entire room. Here, however, a
detected motion should always lead to the same settings regardless of the corner of the room in
which the presence was detected. For this purpose, one detector is switched as master and any
number of others as slaves.
The settings for the master-slave control are made in the menu of the respective light channels.
The master is configured as desired as a fully or half-automatic unit.
A value of 3-5 minutes is recommended for the follow-up time.
Slaves are set as follows:
•
The brightness must be set to "
independent of brightness
".
•
Set the operating mode of the channel to "
fully automatic
".
•
The
follow-up time
should be significantly shorter than that of the master.
•
Object type for output
–
light to “
Switching
”
•
The output object transmits "
only ON
".
•
A value of
30 seconds
is recommended for the time "
sending cyclic ON
".
The "slaves" send their output object for "switch" to the "external motion (slave)" object of the
master.
4.3.9.2 HVAC / Alarm channel
The master-slave control can also be applied to the HVAC/Alarm channels. The settings for the
"slave" are the same as for the slaves for the lighting groups. However, the settings for the brightness
values are omitted for the HVAC/alarm channel. The observation windows are to be set according to
the individual requirements.
Attention
:
If the slave is in its follow-up time, it cyclically sends a "1" to the master. After the last "1"
has been sent to the master, the master's follow-up time elapses before the master switches off its
output. In this case, the follow-up time of the master and slave are added up.
