7.2.6 Time Sensor
The Time sensor is a function which generates an impuls at an
adjustable interval (e.g. every minute, every 5 minutes), thus setting
its Boolean output to "1" for a cycles and then back to "0".
The following settings are possible fo the Interval parameter:
• 1; 2; 5; 10; 15; 30 Seconds,
• 1; 2; 5; 10; 15; 30 Minutes,
• 1; 2; 6; 12; 24 Hours.
The output impulse is thereby always accomplished in synchronized
fashion with the time of day. If, for example, "6 hours" is set, then an
impulse will be generated at 6 AM, 12 AM, 6 PM and 12 PM.
If an impulse is required at particular times of the day, then you
should use a clock timer with a downstream impulse generator
instead of a time sensor (see Chap. 7.2.7).

7.2.7 Clock Timer
The Clock timer is a function which switches on its Boolean output at
a certain time during a month and then switches it off again at a
different point in time.
The switch-on time is set with the parameters Switch-on day and
Switch-on time
, while the switch-off time is set with the parameters
Switch-off day
and Switch-off time.
A weekday "Monday" to "Sunday" can be set. The setting "Daily" is
also possible. The "Daily" setting is only possible if both days are set
to "Daily". The Editor prevent erroneous inputs: If, for example, the
switch-on day is changed from "Monday" to "Daily", then the switch-
off day is automatically set to "Daily".
If switch-on time and switch-off time are identical, the the output will
be switched on for precisely this specified second.
If only one impulse is required, i.e. if the output in intended to be set
for exactly one cycle to "1" and then back to "0", then use a
downstream impulse generator (see Chap. 7.8.6).
