12. Cycle switching commands
If a load with a high switching frequency – in the seconds range –
is switched ON and OFF, it must be ensured that adverse effects on
the quality of lighting units (flicker) and faults in radio and television
reception are avoieded
You determine the times for cyclical switching commands.
Symbols:
= cycle duration
(2...99 sec. or 1...99 min.)
= ON switching duration (1...99 sec. or 1...99 min.)
A cycle switching command consists of
• Start time
• Cycle duration (ON switching du pause)
• ON switching duration
If you assign no End time to a cycle switching command, it operates
continuously.
In practice, an End time will in most cases be a standard OFF
switching command.
However, an End time must be a standard EIB switching command
if its application is to be switched ON at the end of the cycle.
1st Example:
Start time
Monday 09.00
Cycle duration
60 minutes
ON switching duration
10 minutes
End time
Friday 19.00
2nd Example:
Start time
Monday
to
Friday 09.00
Cycle duration
60 minutes
ON switching duration
10 minutes
End time
Monday
to
Friday 19.00
