Figure 3: standard call pushbutton/indicator wiring
Figure 4: call pushbutton wiring for group operation
Figure 4 shows possible call pushbutton wiring in a group (an example on
the figure is for duplex) when each lift has its own serial line with PKN10.
Call and display operation is correct in all modes, including when one of
lifts doesn’t work or is switched off.
Pushbutton backlight (E-type parameter F17) can be active on one PKN10
only, so landing button backlight should be switched off on all other lifts
in the group with the parameter F22.
