ranslation of the original instructions
11.4.2 PHOTOCELL CONNECTION TO RELAYS AND SAFETY DEVICES WITH “N.C.” CONTACT
The E850 board is designed to connect to
closing safety devices
that trip only during gate closing movement, and are therefore
suitable for protecting the gate closing area form risk of impact.
If the connection of two or more safety devices is required (N.C. contacts), they must be placed in series, as
shown in figures 29, 30, and 31 under the wording “SAFE”.

11.4.3 BUS PHOTOCELL CONNECTION
BUS-technology photocells are connected to the E850 control unit ALL IN PARALLEL, as shown in Fig. 32 and Fig. 33 using a single
power supply/communication line.
BUS photocells and pulse generators do not require a matching polarity connection.
The board is designed to connect up to 8 pairs of BUS 2easy photocells.
The photocells are divided by quantity in the following groups:
Pairs of CLOSING photocells:
max 7
Pairs of photocells for OPEN pulse:
max 1
