STEP 6
SYSTEM DEVICE CONNECTION
After installing all devices in the system – each in the position specified in
STEP 4 – connect each device to the control unit as follows.
CAUTION! – Incorrect connections can cause faults or hazards;
therefore ensure that the specified connections are strictly observed.
01. Use a screwdriver to loosen the screw on the control unit cover and
extract the cover (fig. 38), to access the terminals for electrical con-
nections of the control unit.
38
02. Use the same screwdriver to open the slots required for routing the
electric cables (fig. 39) from the various devices in the system.
39
03. Then connect the electric wires of the system devices to the control
unit using the terminal board with five terminals (fig. 39-a).

CAUTION – The section of electric cable connecting terminals 3
and 5 must only be removed if photocell installation is envis-
aged.

For correct connections, proceed as follows:
• To connect a pair of photocells with safety function
One or more pairs of photocells with a safety function must be installed on
the system. If several pairs of photocells are installed, these must be con-
nected in series, and the chain must be connected to terminals 3 and 5
on the control unit. The connect the power supply to terminals 2 and 3
(see example in fig. 40-a and fig. 40-b).
During the Closing manoeuvre, activation of these photocells causes
shutdown of the manoeuvre and immediate inversion of movement.

• To connect a NO type pushbutton used for manoeuvre control
An "NO" type pushbutton can be installed on the system, i.e. "normally
open" to control manoeuvres in "step-step" mode (for details on this
mode, see STEP 9). Connect this pushbutton to terminals 3 and 4 on the
control unit.
Note – If several pushbuttons are installed to control manoeuvres, con-
nect these in parallel as shown in the example in fig. 40-c and fig. 40-d.
