DESCRIPTION
5.2.1. CONNECTOR J1
The connector J1 is used for the quick connection of MINIDEC,
DECODER, RP RECEIVER boards (Figs. 25,26,27).
Accessory boards are to be inserted with their component
sides facing the inside of the 746MPS electronic control unit.
Always disconnect the power supply before inserting or
removing accessory boards.

5 = Common/Negative of accessor y power supply (-)
2 =
OPEN control device (N.O.)
Any control device (pushbutton, detector,..) which,
on closing the contact, relays an open and/or close
impulse to the gate.
To install more than one Open control device, con-
nect the N.O. contacts in parallel.
3 =
STOP control device (N.C.)
Any control device (e.g. pushbutton) w hich, on
opening a contact, stops the movement of the gate.
To install more than one Stop control device, con-
nect the N.C. contacts in series.
Ü
If no Stop control devices are to be connected,
place a jumper across the input and the common
terminal (ter minal 1 or 5).
4 =
FSW closure safety device (N.C.)
Any control device (photocells, safety edges, mag-
netic loops) with an N.C. contact which reverses the
movement of the gate w hen an obstacle is de-
tected within the protected area during the clos-
ing movement. If a closure safety device is tripped
when the gate is open or during a pause time, they
will prevent gate closure. These devices do not in-
ter vene during gate opening movements.
To install more than one safety device, connect the
N.C. contacts in series.
Ü
If no closure safety devices are to be installed,
place a jumper across this input and the common
terminal (ter minal 1or 5).
6 =
24Vdc accessories power supply positive (+)
The maximum load of the accessories is 360mA.
To calculate power draw, refer to the instructions for
the individual accessories.

5.2.3. CONNECTORS J3-J4 (limit switch)
J3 = Connection of limit switch for left-hand closure
J4 = Connection of limit switch for right-hand closure
Refer to Figs. 28-29 for quick connection of the inductive limit
switch sensor for the corresponding gate closure direction.
