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.
02. Use the same screwdriver to open the slots required for routing the
electric cables (
fig. 39 ) from the various devices in the system.
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 .
