Communication objects
You can select the following communication objects:
Per input:
You can address two actuator groups with 1 or 8 bits
simultaneously.
Depending on the parameter settings, one of the follo-
wing will be transmitted via the switch/value object
whenever a key is pressed:
– an ON or OFF telegram
– 1 byte values (0 % - 100 % in levels)
– 1 byte values (0 - 255) infinitely
– two objects, (1 bit / 1 byte) in any combination
sent via the switch/value object.
Communication objects
You can select the following communication objects:
Per input:
You can use the dimming function for the following:
– dim brighter
and
darker via
one key
(single-surface
dimming)
– either dim brighter
or
darker. You need a second key
(second input) to dim in the other direction (dual-sur-
face dimming).
You can use the corresponding key (input) to switch
the light on or off (press key briefly) or dim it (press key
for a longer period, the parameters for the exact period
can be set). When switching takes place, an ON/OFF
telegram is sent via the switch object. When dimming,
dimming up or dimming down is carried out via the 4-
bit dimming object; the parameters for the dimming
steps can be set. In addition, you can also transmit the
corresponding dimming step cyclically for a period of
time which can be set as required.
Common parameters for single-surface and dual-
surface dimming
Additional parameters for single-surface dimming
You can dim brighter or darker and also switch on or off
using a single key.
The current switching or dimming direction is always
dependent on the previous action, i. e. if switched off,
pressing the key briefly will switch the light on and vice
versa, and if the light has been dimmed up, prolonged
activation of the key will dim the light down again. On
release after prolonged activation, a stop telegram will
be sent via the 4-bit dimming object, thus terminating
the dimming procedure in the dimming actuator.
An update or change to the switch/object value is pos-
sible via the bus when another sensor switches or
dims the actuator (e.g. via a two-way circuit or a central
command). To prevent the "wrong" switching/dimming
activity, you must load the status of the actuator into
the push-button interface. To do this, connect the
group address of the second sensor to the switch/dim-
ming object of the push-button interface.
A single command is sufficient to cycle through the
dimming range. This dimming procedure can be used
for most applications. The other possible dimming
steps (1/2 - 1/64 brighter or darker) dim brighter or dar-
ker by the selected step. For example, to dim from
min. to max. brightness, you would need to push the
key for a prolonged period four times in succession if
the level set is 1/4.
