Controller
Parameter
Setting
Maximal deviation from setpoint value (hysteresis)
+/- 5%
+/- 10%
+/- 15%
+/- 20%
This parameter determines the difference between current value and setpoint value that activates the controller.
This parameter only affects the control of the main lighting group.
Send dimming value every (controller speed)
1 second
2 seconds
3 seconds
5 seconds
10 seconds
20 seconds
This parameter determines the interval for sending the calculated control values.
Note: When an external measurement is used then setting the parameter to 1 second makes sense, assuming that the external value
is received within half of the time selected here. When the internal measurement is used this parameter should be set to a value that is
at
least double the value of the parameter setting of “Number of values for calculation of average”.
Timeout for automatic off [min]
(0 = no automatic off)
0
– 230,
3
If the actuating variable of the
controller in the “active” state has reached the configured minimum level and at the same time the
current
value of the measured brightness is higher than the brightness setpoint, then the controller changes into the state “standby”
and sends a switching
telegram with the value “Off”.
The period from reaching the condition described above to switching into the state “standby” is determined by the previous parameter
in the range 1-
255 minutes. If that parameter is set to “0” then the controller remains in the state “active” with the minimum control
values.
Additional hysteresis for restart when controller was
in standby
[LUX]
0
– 230,
100
When the controller is in the state “standby” and the current light level value drops below the setpoint value minus hysteresis minus
additional hysteresis then the controller automatically changes into the state “active”.
Note: If setpoint value minus hysteresis minus additional hysteresis is lower than 50 LUX, then 50 LUX is used as the limit for changing
back to the state “active”.
Start and finish constant light level control with
only dimming-value telegram
additional switching telegram at begin of control
additional switching telegram at stop of control
additional switching telegram at begin and stop
This parameter determines the type of telegrams sent by the constant light level controller on start and ending of the control activity
(switching into state “active” respectively leaving the “active” state).
Controller Output
Parameter
Setting
Max. step for dimming
1 (0,5%); 3 (1,1%); 4 (1,5%);
5 (2,0%)
; 6 (2,5%), 7 (2,7%);
10 (3,9%)
This parameter determines the maximum step of the control value to be used for dimming.
Note: The maximum step for dimming should be chosen such that a change of the dimming value does not change the illumination
more than the configured hysteresis of the set point.
First dim-value, when control starts
copy from parameter
query from actuator’s status
calculate start value
This parameter determines how the first dimming value (starting value) for the control is established.
query from actuator’s status
(default setting):
The current control value of the dimming actuator is interrogated via a status read request and the control loop is started with this
value.
This action takes into account that the dimming value could have been changed by a relative dimming command while the control
loop was inactive. The status read request does not work with all DALI Gateways.
calculate start value
:
Before the control starts the current actual value is measured. This value represents the mixed light (daylight and artificial light). Using
the calibration curve the measured value of the room brightness is then computed into the control value, which is used as a starting
value for the control.
copy from parameter
:
This parameter setting is used if the other two options do not apply.
