DESCRIPTION

5.2.1. CONNECTOR J1

The connector J1 is used for the quick connection of
MINIDEC,DECODER, RP RECEIVER boards (Figs. 21,22,23).
Accessory boards are to be inserted with their component
sides facing the inside of the 844MPSR electronic control unit.
Always disconnect the power supply before inserting or
removing accessory boards.

5.2.2. TERMINAL BLOCK J2 (low voltage)

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.
If no Stop control devices are to be connected,
place a jumper across the input and the common
terminal (terminal 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 interrupts

the movement of the gate when an obstacle is de-
tected within the protected area.
The task of the closure safety device is to safeguard
the area occupied by the gate during the closing
movement.
The inter vention of safety devices during gate clo-
sure causes the direction of gate movement to be
reversed. These devices do not inter vene dur ing
gate opening movements. If a closure safety device
is tripped when the gate is open or during a pause
time, they will prevent gate closure.
To install more than one safety device, connect the
N.C. contacts in series.
If no closure safety devices are to be installed, place
a jumper across this input and the common ter mi-
nal (terminal 1 or 5).

8 = 24V

~ accessories power supply

The maximum load of the accessories is 500 mA.
To calculate power draw, refer to the instructions for
the individual accessories.
If the jumper LK1 is broken, the 24V~ accessories
power supply is no longer available (Fig.28).

7 =

24Vdc

accessories power supply positive (+)

The maximum load of the accessories is 500 mA.
To calculate power draw, refer to the instructions for
the individual accessories.

9 =

Electric lock output (12 Vac)

F o r o p e ra t i o n o f t h e e l e c t r i c l o ck , re fe r t o t h e
dipswitch settings. If two electric locks are installed,
they must be connected in series.

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. 24-25 for quick connection of the inductive limit
switch sensor for the corresponding gate closure direction.
