6.4 – INSTALLING AND CONNECTING
PHOTOCELL MODELS MP
The pair of photocells is made up of one photocell that transmits (named
TX) and one that receives (named RX). TX and RX are marked by a label
inside the cover. The photocells are installed on each side of the point of
transit and are connected to the control unit via the flashing light by
means of the BUS cable.
The photocells are safety devices that enable the detection of obstacles
when the latter cross the trajectory of the two photocells. The system can
be equipped with up to 6 pairs of photocells for safety and a pair of pho-
tocells used to command an Opening manoeuvre only (to install addition-
al photocells, refer to section "Selecting operating modes of photocell
pairs").
