Light Management
Pushbutton control unit
Ref.-no.: 1240 STE
R3
Operation when the device is on:
Brief depression (less than 400 ms):
UPPER pushbutton or LOWER pushbutton or both: OFF.
Long depression (longer than 400 ms):
UPPER pushbutton: increasing the brightness up to maximum.
LOWER pushbutton: reducing the brightness down to minimum.
Both pushbutton faces (at least 3 seconds):
The current brightness level is stored in an NV memory and recalled
when the device is switched on again (brief press). Storage is confirmed
by cutting out the lamp for 1 second and by subsequent restarting with
the stored brightness value.
Storing a memory value
When an automatic-switch ‘Universal’ is used, a memory value can be
saved via an extension. The saving procedure is described at length in
the operating instructions of the attachment.
Adjustment of basic brightness
Important:
When using the multifunction pushbutton ‘Universal’ as a time
switch, the basic brightness is stored only in the pushbutton.
The basic brightness value is saved in a non-volatile memory. The
adjustment as such can only be made directly on the pushbutton control
unit itself. For storing, press the center of the button (not multifunction
pushbutton with radio-control receiver and multifunction pushbutton
‘Universal’) for at least 20 seconds when off. The lights are at first set to
maximum brightness. After ca. 20 seconds, the device switches to 50%
brightness to confirm that it is ready for programming. Now dim the lights
until the desired basic brightness is reached. Release the key. After ca.
20 seconds, the basic brightness is saved and the load switched off for
confirmation. If the basic brightness is to be stored during operation of the
pushbutton control unit with a presence detector, an automatic switch, a
multifunction pushbutton or a multifunction pushbutton with radio-control
receiver, proceed as follows:
Attention: Observe the safety warnings.
1. Disconnect the mains voltage.
2. Withdraw the presence detector, automatic switch,
multifunction pushbutton or multifunction pushbutton with
radio-control receiver from the insert.
3. Plug a pushbutton on the insert.
4. Switch on the mains supply.
5. Adjust the basic brightness (see above).
6. Disconnect the mains voltage.
7. Withdraw the pushbutton from the insert.
8. Plug the presence detector, automatic switch, multifunction
pushbutton or multifunction pushbutton with radio-control
receiver on the insert.
9. Switch on the mains voltage.
