"0" Device operates without any errors
"1" Malfunction
Object: "Error code": 1 Byte (EIS14)
(only Universal Dim Actuator Module UD/M 1.300.1)
This object provides more detailed information about the cause of an error.
The object value is sent in the event of a change.
Bit0: Error during load detection
Bit1: (not used)
Bit2: (not used)
Bit3: No-load operation or low load
Bit4: Short circuit or overload
Bit5: Overvoltage in load circuit (overvoltage pulse)
Bit6: Excess temperature in device
Bit7: Critical temperature rise in device
Object: "Light sensor value": 1 Byte (EIS6)
(only Light Controller Module LR/M 1.6.1)
This object sends the brightness value that is measured by the light sensor.
Objects: "Call preset 1/2" and "Call preset 3/4": 1 Bit (EIS1)
Retrieves a stored brightness value. The object values "0" or "1" retrieve the
brightness values "Brightness 1" or "Brightness 2" and "Brightness 3" or
"Brightness 4".
For "Brightness 1" or "Brightness 3", it is also possible to specify that the
state is restored before retrieving "Brightness 2" or "Brightness 4" or the
stored brightness value is reset to the parameterised value (advisable, if
brightness 2 or brightness 4 can be stored).
Objects: "Set preset 1/2" and "Set preset 3/4": 1 Bit (EIS1)
Stores the brightness value that is currently issued as a new preset value.
The object values "0" or "1" store preset1 or preset2 (and preset3 or
preset4).
Object: "Set setpoint value": 1 Bit (EIS1)
If the device receives the value "1" via this object, the current actual value of
the light sensor is transferred to the object value "Setpoint value" and sent
on the bus. The control function thus sets the current brightness value as a
new setpoint value.
Object: "Setpoint value": 1 Byte (EIS6)
The setpoint value of the lighting control can be read out via this object and
directly assigned.
Object: "Slave brightness value": 1 Byte (EIS6)
This object is visible if the parameter "Light controller operates as 'master' of
other dimmers" = "yes". It sends the current brightness value of the controller
on the bus so that further devices ("Slaves") can be set to the same value.
Object: "Control active/inactive": 1 Bit (EIS1)
After an activation/deactivation of the lighting control, this objects sends its
new status on the bus ("1" = control active, "0" = control inactive).
By writing to this object, the lighting control can be deactivated ("1") and
activated ("0"). When the control is deactivated, the brightness value initially
remains unchanged.
