Chaser light
Task definition
Say that you want to use the easyE4 to switch on four lamps in sequence and then
switch them off accordingly.
Starting from the first lamp all the way to the fourth lamp, and then vice versa from the
fourth lamp all the way to the first lamp, and so on. The system can be switched on and
off with main switch S1.
The selector switch S2 defines whether the chaser light is to be activated permanently
or only at the set times (daily from 6 PM to 10 PM).
Three different speeds can be set for the chaser light:
l
Switch S3 > Fast chaser light speed (0.30 sec.)
l
Switch S4 > Medium chaser light speed (0.60 sec)
l
Switches S3 and S4 simultaneously > Slow chaser light speed (1 sec)
