4.1.3.17 Option: Setup Progr. Pulses
Timer Mode
This mode simulates a programmable day assigned timer. Three turn-off and turn-on times are programmable for
each output. If you want to program a switchtime, change the turn-on time "On" and the corresponding turn-off
time "Off". A turn-on time later than the turn-off time would cause a switch program running over midnight. For
example a program "On"10.45.00, "Off" 9.30.00 would cause an active ouput from 10.45 to 9.30 (the next day!). If
one or more of the three switching times are unused just enter the same time into the values "On" and "Off". In
this case the switch time does not affect the output.

Cyclic Pulse mode - generating of periodically repeated pulses
The value of "Time" determines the time between two consecutive pulses. This cycle time must be entered as
hours, minutes and seconds. The pulse train is synchronized at 0:00 o’clock local time, so the first pulse of a
day always occurs at midnight. A cycle time of 2 seconds for example, would cause pulses at 0:00:00, 0:00:02,
0:00:04 etc. Basically it is possible to enter any cycle time between 0 and 24 hours, however usually a cycle
times that cause a constant distance between all consecutive pulses make sense.
For example: a cycle time of 1 hour 45 minutes would cause a pulse every 6300 seconds (starting from 0
o’clock). The appearing distance between the last pulse of a day and the first pulse of the next day (0:00:00
o’clock) would be only 4500 sec. The value in entry field "Cycle" turns red, when entering a time that causes
this asymmetry.
DCF77 Marks
In "DCF77 Marks" mode the selected output simulates the telegram as transmitted by german time code trans-
mitter DCF77. The generated time code is related to the local time zone. If you want DCF simulation to
be disabled when the clock is in free running mode, you can enter the delay (given in minutes) for deactivat-
