6. ELECTRICAL SYSTEM
ATTENTION: Before attempting any work on the board
(connections, maintenance), always turn off power.
The specifications of the electrical system are included in the
chapter “Warnings for the installer”. Always separate power
cables from control cables.
To prevent any electric noise whatever, use separate sheaths.
The 540 operator is supplied with the 200BT equipment on board.
The 541 operator is supplied with an on-board inter-connection
board.
6.1 CONNECTIONS OF 200BT ELECTRONIC EQUIPMENT
Lay the raceways as shown in fig. 3 and make the 200BT operator
external connections as shown in fig. 15.
To assign OPEN and CLOSE commands to inputs IN1 and IN2,
refer to paragraph 5.2.1.
Do not modify the operator internal connections.
If you wish to use the 541 operator (with on-board inter-
connection board) and the 200BT remote equipment, take the
230Vac power supply only to the equipment and connect the
terminals of the latter to those of the inter-connection board,
observing correct wire matching.
The 200BT equipment operates in “dead-man” mode: the
opening and closing command must be manually maintained
through the entire manoeuvre.
The command generators - consistently and univocally identified
- must be installed in a position enabling the manoeuvring person
to have direct visual control of the door and surrounding area.
6.2 CONNECTIONS OF 578D ELECTRONIC EQUIPMENT
Lay the raceways according to the instructions in figure 4.
Make the connections between the 578D equipment and the
inter-connection board mounted on the operator, observing
the diagram in fig.16.
A STOP push-button, if any, must be located in series with respect
to the connection between the STOP input of 578D and the
SAFETY of the 541 INTERFACE.
For wiring and programming the 578D, consult the instructions for
the equipment.

5.6 ADJUSTMENT OF LIMIT-SWITCH UNIT
Fully close the door.
Remove the square under the ring-nuts stop spring.
Keep the spring lifted up (see figure 14) and turn the ring-nut of
the closing limit-switch until the latter is activated. Turn the other
ring-nut until it is near the first one and re-position the stop spring
on the ring-nuts.
Move the door by hand to open position until the mechanical
buffers are slightly compressed.
Lift up the spring, turn the ring-nut of the opening limit-switch
until the latter is activated and re-position the spring.
Check if the operator activation makes it possible to reach the
required positions. If not, correct the position of the ring-nuts.
If using the 578D equipment, you can correct the closing stop
point also by varying the post-travel limit deceleration
parameter.
