5. Connection of extension units
Switching / dimming from several places with the "2-wire" extension unit
(8), the "3-wire" extension unit (9) or a mechanical pushbutton (10), see
fig. B.
Contrary to the "2-wire" extension unit, the N conductor in the "3-wire"
extension unit must be connected, too.
The "2-wire" extension unit, the "3-wire" extension unit and the
mechanical pushbuttons can be used together in combination with each
other.
"3-wire" extension unit used with the presence detector (art. no.
PMS360WW) or the automatic switch attachment (art. no. ..1180-1..,
..1280-1..): available functions see operating instructions of the
respective attachment
Functions available only if an automatic switch or a presence
detector attachment is used also on the main unit.
Extension unit "2-wire" :
with short-stroke key. Same functions as with the pushbutton contro
unit, adjustment of basic brightness not possible.
Mechanical pushbutton (make contact):
short depression : ON / OFF
long depression : dimming
Illuminated mechanical pushbuttons must have a separate N terminal.
A short depression in the off-state switches the load on with the memory
value. A long depression in the off-state increases first the brightness to
maximum, the lamp remains at maximum for about 1 second and is then
reduced to minimum brightness. The lamp remains at minimum for about
1 second and is then increased again to maximum brightness. The cycle
is continuously repeated. Storing of a desired brightness is not possible
with the mechanical pushbutton (make contact).
