3.2.3 Description of objects
•
Objects 0, 30, 80, 110, "Switching ON/OFF"
A 1 on this object dims up to 100%,
and 0 dims to 0%
•
Objects 1, 31, 81, 111, "brighter/darker"
This object is actuated with 4-bit telegrams (DPT 3.007 Control Dimming).
This function can be used to dim the light up or down
in increments.
In the standard application, telegrams are sent with 64 increments.
IMPORTANT:
The response to 4-bit telegrams depends on the
“Switching On/Off with a 4-bit telegram” parameter.
See appendix: 4-bit telegrams (brighter/darker)
•
Objects 2, 32, 82, 112, "Dimming value"
This object can be used to select the desired dimmer setting directly.
Format: 1 byte percentage value EIS 2 dimming, value.
0 = 0%
255 = 100%
•
Objects 3, 33, 83, 113 „Soft switching“
A “1” on this object starts a soft switching cycle, i.e.:
The brightness is gradually increased, starting from the minimum brightness.
The dimming value remains constant for the programmed time and is then gradually reduced after this
time has elapsed.
Once the programmed minimum brightness has been reached, the dimming value is reset to 0%.
The cycle can be extended or prematurely terminated via telegrams
This sequence can also be controlled using a
time switch
if the "
Time between soft ON and soft OFF
"
parameter is set to "
Until soft OFF telegram
".
The dimming cycle is then started with a “1” and finished with a “0”.
See appendix: Use of the soft switch function
•
Object 4, 34, 84, 114 "Block"
Responses to setting and cancelling the block can be configured if the block function has been
activated (parameter page
Channel C1/C2 Configuration options
).
The block only applies when the object is received, i.e. with
Block with OFF telegram
the channel is
not blocked after restoration of the bus supply.
If the parameter
Behaviour when setting the block
=
no reaction
, a running soft-switch process will not
be interrupted.
