Figure 81: EZ circuit diagram stairwell lighting
Meaning of the contacts and relays used:
• I1: ON/OFF pushbutton
• Q1: Output relay for light ON/OFF
• M1: Marker relay. This is used to block the “switch off
automatically after 6 minutes” function for continuous
lighting.
• T1 Cycle pulse for switching Q1 on and off, (
ü, single-pulse
with value 00.00 s)
• T2 Scan to determine how long the button was pressed. If
pressed longer than 5 s, continuous lighting is switched on
(
X, on-delayed, value 5 s).
• T3 switch off after a lighting time of 6 min. (
X, on-delayed,
value 6:00 min.).
• T4 Switch off after 4 hours continuous lighting (
X, on-
delayed, value 4:00 h).
If you are using an EZ with a time switch, you can define both
the stairwell lighting and the continuous lighting periods via
the time switch.
The EZ circuit diagram for the
functions described above looks
like this:
The enhanced EZ circuit diagram:
after four hours, the continuous
lighting is also switched off.
