Glass Push Button II Lite [BE-GTLxxx.x1]
Button functions
The button settings specify whether the buttons are assigned to single or paired functions. The default
setting is vertical. It is possible to select two different models for the single button function.
not active: If the buttons are deactivated, they can not be configured further.
■
single-button function (1 function, top/bottom together): In this case, only button 1 appears as a
■
submenu for buttons 1/2. The setting made there automatically refers to button 2 as well.
single-button function (2 functions, top/bottom): Submenus appear for both buttons, which can be
■
configured independently of each other.
two-button function: This function represents a classic rocker switch. If either function is selected,
■
both buttons are assigned clear actions. If, for example, 'Switching' is selected, it is possible to specify
that one button sends an 'On' signal and the other consequently an 'Off' signal.
Slap/Cleaning function
When the Slap/Cleaning function is activated, an additional submenu is displayed in which this function
can be configured. The polarity, i.e. whether the "Slap function" or the "Cleaning function" should be
activated by a short or long button press, can also be set here.
The "Slap function", which is triggered by touching the button over its entire surface, allows intuitive
operation. This function can be used, for example, to switch on the light when entering the room without
the user having to search for the exact position of the single buttons. Here, a fast reaction time on keypress
is recommended to achieve a quick response.
The "Cleaning function"
surface is touched over the entire area for the appropriate time (e.g. long button, 0.4 seconds), the status
LEDs start to flash. The glass can be cleaned during this time. After a fixed time of 10 seconds, the LEDs
turn off and the button is in normal operation.
Note: "Entire surface of the buttons" means that at least three Sensor surfaces must be touched
simultaneously.
Reaction time on keypress
The reaction time is used to debounce the buttons. It can be selected as slow, medium or fast and defines
how long a button must be pressed to generate a function call.
Note: A fast reaction time is recommended for the Multitouch function.
Time for long keypress (Basic setting)
The "Time for long keypress" parameter can be used to assign a fixed time value to the button, from which
point it recognises a button press as long. This parameter is important for objects that have both, short and
long button press functions.
