Parameter

- Operating modes

The operating mode in which this block operates is specified 

in the application software for each block (movement blocks 
1 - 5). The following operating modes are available:
– Normal operation
– Master mode
– Slave mode
– Monitoring mode
Depending on the operating mode different parameters and 

communication objects will be displayed. Each operating 

mode can operate brightness-dependently or non-
brightness-dependently. 

Normal operation

In this operating mode the movement detector does not have 

any external trigger objects (master trigger object, trigger 
object). Telegrams cannot be sent cyclically and this means 

a master-slave system cannot be set up. In the default 

setting, the movement detector transmits an ON telegram at 
the start of movement and transmits an OFF telegram when 

the movement time (staircase timer) has expired.

|

Note:

Use the "Normal operation" setting when the 
movement detector is working for itself alone. In 

other words, one movement detector is used for each 

room and it switches one light or one light panel.

Master mode

With master mode all of the possible parameters and 

communication objects of the movement detector are 

available. A master-slave system can be set up with the aid 
of the master trigger object or the trigger object.  In the 

default setting, the movement detector transmits an ON 

telegram at the start of movement and transmits an OFF 
telegram when the movement time (staircase timer) has 

expired.

Slave mode

In slave mode the default setting is that ON telegrams are 
sent cyclically when a movement is detected. These 

telegrams are intended for the master trigger object or for the 

trigger object of the master.

Monitoring mode

In monitoring mode the default setting is that ON telegrams 

are sent cyclically when a movement is detected. At the end 

of the movement time (cycle time with movement) OFF 
telegrams are transmitted cyclically.

|

Note:

Use the "Monitoring mode" setting when the 

movementmovement detector is being used for room 
monitoring and telegrams are to be sent cyclically on 

the bus.
