Activating and deactivating grid synchronisation
Cycle function
Only available in EXPERT mode
For cyclical switch commands the switching on time is set by logical "OR" of programs of all types. A fixed cycle of ON and OFF time then operates
within those limits. The cycle always starts with the ON time.
The cycle duration and the ON time within the cycle have the same length for all switching times. The cycle duration and the ON time can be set inde-
pendently in one-second increments. If the switching time is shorter than the cycle duration, the cycle will be shortened accordingly. The ON time will
remain unchanged. If the switching time is actually shorter than the ON time, the ON time will be shortened accordingly.

Only available in EXPERT mode. The synchronisa-
tion can only be activated when no antenna is con-
nected.
The default setting is PASSIVE. In order to improve
the long-term accuracy, it is advisable to activate
synchronisation if the time switch is
supplied from a on 50/60 Hz grid with frequency
adjustment.
