How does the staircase lighting react on bus voltage failure?
Reaction in the event of bus voltage failure is specified by the parameter
Reaction on bus voltage failure

parameter window
A: General.
How does the staircase lighting react on bus voltage recovery?
Reaction on bus voltage recovery is defined by two conditions.
A
By the communication object
Disable time function
. If staircase lighting is disabled after bus voltage
recovery, it can only be switched on or off via the communication object
Switch
.
B
By the parameterization of the communication object
Switch
. Whether the light is switched on or off
on bus voltage recovery depends on the settings of
Switch
.
Restart of staircase time after
end of permanent ON
Options:
no
yes
•
no
: The lighting switches off if
Permanent ON
is ended.
•
yes
: The lighting remains on and the staircase lighting time restarts.
The function of Permanent ON is controlled via the communication object value
Permanent ON
. If the
communication object receives a telegram with the value 1, the output is switched on regardless of the
value of the communication object
Switch
and remains switched on until the communication object
Permanent ON
has the value 0.
Please note
Permanent ON
only switches ON and “masks” the other functions. This means that the other functions,
e.g. Staircase lighting time or “Pumping up”, continue to run in the background but do not initiate any
action. After
Permanent ON
ends, the contact position which would result without the
permanent ON
function becomes active.
