Technical Manual
Glass Push Button II Lite [BE-GTLxxx.x1]
Startup time
This time defines when the unit boots up after a restart (reset, reprogramming, bus voltage recovery). This
can be important if 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.
"In operation"
This parameter is used to show on the bus that the device is "alive". If activated, an ON telegram is sent
cyclically.
Button operation
The communication object "Button operation – Output" is switched every time a button is pressed,
regardless of which button is pressed. This can be used, for example to switch "on" an orientation light.
Note: A time-out of 30 seconds is restarted after each button press. No new telegram is sent via this
communication object during the active time-out.
The following table shows the associated communication objects:
No. Name/Object function
71 Day/Night – Day = 1 / Night = 0
71 Day/Night – Night = 1 / Day = 0
72 Button operation – Output
77 In operation – Output
