Q1
The diagram shows the circuit for an input with an associated output.
This switch offers the following:
S When the switch is pressed: The light is switched on and goes off
again after the set time of 6 minutes (T=06:00m) has elapsed (off-delay)
S When the switch is pressed twice: The light is switched on perma-
nently (the latching relay is set via the impulse relay).
S When the switch is pressed for 2 seconds: The light is switched off
(on-delay switches the light off; both the permanent light and the normal
light; this branch of the circuit is therefore used twice)
You can enter these circuits several times for the remaining inputs and out-
puts. Instead of using 4 automatic stairway lighting systems or 4 impulse
relays, you thus use only a single LOGO! module. However, you can also
use the free inputs and outputs for completely different functions.
