9.6 PROGRAM menu: CYCLE
In addition to programming switching times and pulses in the case of devices TR 611 top2, TR 622 top2
and TR 611 top2 RC you can programme cyclical repetitive switchings (CYCLE) very quickly and with a
reduced memory space requirement.
A CYCLE program is also comprised of 4 input steps:
Step 1: START CYCLE =
Start time of the cycle program
Step 2: PULSE DURATION =
Duration of the switch-on (Pulse), which is constantly
repeated after the pause has elapsed to the
end of the cycle program.
Step 3: PAUSE
= Pause duration (switch-off) between each pulse
Step 4: STOP CYCLE =
End of the cycle program
After programming these 4 parameters the cycle program operates in such a way that after the cycle
start the pulse times (ON switchings) and pause times (OFF switchings) are repeated as often as
possible until the end of the cycle program is reached.
Example:
In the figure shown the cycle start is at 11:00 am, the pulse duration lasts for 20 seconds, the pause
lasts for 29 minutes and 40 seconds and the cycle is stopped at 10:00 pm.
It is therefore switched on as from 11:00 am to 10:00 pm every half hour for 20 seconds.
Typical applications for CYCLE programs are toilet flushing cycles and ventilation control systems.
Example for programming a CYCLE:
With the C1 channel the time switch should switch on the ventilation of a workshop between
Monday 9:00 am and Friday 5:00 pm day and night, on the hour, for 10 minutes. At the weekend
ventilation is not required.
Programming via "normal" switching times would be very time-consuming:
Switching time 1: Monday
– Friday 9:00 am 
ON
Switching time 2: Monday
– Friday 9:10 am

OFF
Switching time 3: Monday
– Friday 10:00 am 
ON
Switching time 4: Monday
– Friday 10:10 am 
OFF
etc.
This switching task can be programmed much more easily and quickly than CYCLE.
