Presetting the ON-delay for the staircase function
An ON-telegram to activate the staircase function can also be evaluated with a time delay. This ON-delay
can be activated separately for the staircase function and has no influence on the parameterizable time
delays for the "Switching" object.
The staircase function must have been enabled on parameter page "Ax – Enabled functions (x = number of
output).
Set the parameter "Activate ON-delay for staircase function ?" on parameter page "Ax – staircase
function" to "Yes".
The ON-delay for the staircase function is now enabled and the desired ON-delay time can be preset.
The ON-delay is started after reception of an ON-telegram to the "Staircase function start / stop" object.
A subsequent ON-telegram retriggers the time only if the parameter "ON-delay retriggerable?" has been
set to "Yes". The staircase time is activated and the output switched on only after the time delay has
elapsed.
An OFF telegram via the "Staircase function start / stop" object during the ON-delay ends the delay only if
the parameter "Reaction to OFF telegram" is set to "switching off". Otherwise the OFF telegram will be
ignored.
Presetting the pre-warning function of the staircase function
The pre-warning function complies with DIN 18015-2 and is designed to warn a person in the staircase that
the lights will go out shortly. As a pre-warning, the lamps connected to the output are switched off several
times for a short instant before the output is shut off definitely. The pre-warning time (T
pre-warn
), the duration
of the interruptions during the pre-warning (T
interrupt
) and the number of pre-warning interruptions can be
parameterized (cf. Fig. 17 - example). The pre-warning time is added to the staircase lighting time (T
ON.
).
The pre-warning time has an influence on the value of the feedback object so that the value "0" (non-
inverted transmission) is tracked in the feedback object only after the pre-warning time has elapsed.
