Presetting the behaviour of the staircase function after bus voltage return
The staircase function can optionally be started automatically after bus voltage return.
The staircase function must have been enabled on parameter page "Ax – Enabled functions (x = number of
output).
Set the parameter "Behaviour after bus or mains voltage return" on parameter page "Ax – General" to
"Activate staircase function".
The staircase lighting time of the staircase function is started immediately after bus voltage return.
For this setting it is indispensable that the staircase function has been programmed and enabled
beforehand. When the staircase function has not been enabled, this setting will produce no reaction after
return of the bus or mains voltage.
During an automatic start of the staircase function after return of the bus or mains voltage, an ON-delay –
even if parameterized in the staircase function – will not be started.
The device adopts the parameterized behaviour only if the last ETS programming of the application or of
the parameters occurred at least ca. 20 s ago. Otherwise (T
ETS
< 20 s), the "Behaviour after ETS
programming" will be adopted even after a return of bus voltage.
If only the mains voltage fails after an ETS download and is then switched on again, the actuator
executes the "Behaviour after bus or mains voltage return".
The parameterized behaviour will only be adopted, if no forced control is activated after a bus voltage
return.
A switching state set after bus or mains voltage return will be tracked in the feedback object as provided
for in the "Mode of operation" parameter.
