Table 6: General settings
Startup time
This time defines when the unit "boots up" after a restart (reset, reprogramming, bus voltage
recovery). This can be important if - example 1 - a bus reset is carried out. If there are many units on
a line, all units would start at the same time and load the bus. With a variable time, the units can thus
start differently.
Example 2:
If “Time/Date”, “
S
tatus for toggle” or “Day/Night” object are queried, it makes sense that
the units responsible for them start up first, this unit only a little later. This ensures that all values are
available and correct.
„In operation“
"In operation" is used to show on the bus that the unit is "alive". If activated, an ON telegram is sent
cyclically.
Value for Day/Night
:
Here the polarity for “Day/Night” is defined. Regardle
ss of this polarity, the device always starts in
“Day”
-mode after reprogramming.
Menu language
The set language refers to the "Programming mode" menu (accessible by simultaneously touching
the hidden sensor surfaces on the bottom right and left).
The
object " Button operation
" is permanently displayed. A "1" is sent via this object when any
button is pressed. If buttons are pressed at short intervals, the next telegram is sent at the earliest
after a fixed delay of 30 seconds.
