Example Program for ALPHA Series

1. Lighting Control in Passages and Stairs

 

 

In this example the lighting in passages and stairs is controlled by switches and the Time Switch function block. The lights are automatically switched ON in the evening using Time Switch and automatically switched OFF using Delay Timer when they were left on unintentionally.

Contents of Control:

  1. Operating any switch (S1, S2, S3) switches the lights ON or OFF.
    For example, the lights can be switched ON by S1 and then switched OFF by S3. Operating the same switch twice performs the same operation.
  2. Automatic switch OFF function (six minutes)
    If the "continuous" switch is set to OFF, the lights are automatically turned OFF six minutes after they were turned ON by S1 to S3. Otherwise, the lights are turned OFF, if any switch S1 to S3 is operated within six minutes.
  3. Invalidity of automatic switch OFF function
    If the "continuous" switch S4 is set to ON, automatic switch OFF as explained in 2) is deactivated. The lights are switched OFF only by operating the switches S1 to S3.
  4. Automatic switch ON function
    The lights are switched ON from 18:00 to 22:00 daily. During this period operation by S1 to S3 is deactivated.
