Functional description
Setting supplementary function of the staircase function – time preset via the bus
With the time preset via the bus, the configured staircase time can be multiplied by an
8-bit factor received via the bus, thus it can be adapted dynamically. With this setting, the factor
is derived from the object "staircase time factor". The possible factor value for setting the
staircase time is between 1…255.
The entire staircase time arises as a product from factor (object value) and the configured
staircase time as a basis as follows...
Staircase time = (staircase time object value) x (staircase time parameter)
Example:
Object value "staircase time factor" = 5; parameter "staircase value" = 10s.
-> set staircase time = 5 x 10s = 50 s
Alternatively, the staircase function parameter can define whether the receipt of a new factor
also starts the staircase time of the staircase function at the same time. In this case, the object
"Staircase function start/stop" is not necessary and the received factor value determines the
starting and stopping.
o Set "supplementary function for staircase function" to "time preset via the bus" and set the
parameter "staircase function activatable via 'staircase time' object ?" to "No".
The staircase time can be adapted dynamically by the object "staircase time factor". A
value "0" is interpreted as value "1". The staircase function is started and stopped
exclusively via the "staircase function start / stop" object.
o Set "supplementary function for staircase function" to "time preset via the bus" and set the
parameter "staircase function activatable via 'staircase time' object ?" to "Yes".
The staircase time can be adapted dynamically by the "staircase time factor" object. In
addition, the staircase function is started with the new staircase time (the "staircase
function start / stop" is not necessary) after receiving a new factor. A factor value "0" is
interpreted as an OFF telegram, whereby in this case, the configured reaction to an OFF
telegram is evaluated, too.
A larger staircase with several floors is an example as an application for the time preset via
the bus with automatic starting of the staircase time. On each floor there is a pushbutton
that transmits a factor value to the staircase function. The higher the floor, the greater the
factor value transmitted so that the lighting stays switched on longer if the passing through
the staircase needs more time. When a person enters a staircase and a pushbutton is
pressed, the staircase time is now adjusted dynamically to the staircase time and switches
on the lighting at the same time, too.
i Setting "Staircase function activatable via"Staircase time" object ?" = "Yes":
A factor > 0 received during a warning time triggers the staircase time independently of the
parameter "staircase time retriggerable ?" always afterwards.
i After a reset (bus voltage return or ETS programming) the "staircase time factor" object is
always initialised with "1". The staircase function is not started automatically solely as the
result of this, however.
i The two supplementary functions "time extension" and "time preset via the bus" can only
be configured alternatively.
Presetting behaviour of the staircase function after bus or mains voltage return
The staircase function can be started automatically after bus or mains voltage return.
The staircase function must be enabled.
o In the parameter node "Addressing -> Groups ... -> [x] Group" or "Addressing -> Single
devices ... -> [x] Electronic ballast", set the parameter "Behaviour after bus voltage return"
to "Start staircase function".
Immediately after bus or mains voltage return, the staircase time of the staircase function is
started.
