ÜAlways disconnect the electrical power supply before carrying
out any operations on the control unit (connections, programming,
maintenance).
Warning: On disconnecting connector J6, high voltages may be
present on the capacitor output.
Observe points 10, 11, 12, 13 and 14 in the GENERAL SAFETY

connections from the 844 MPS electronic control unit to the
chosen accessories.
Always route the power supply cables separately from the
control and safety cables (keyswitch, receiver, photocells,
etc.). Use separate conduits to avoid any interference.

5.2. 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 844MPS electronic control unit.
Always disconnect the power supply before inserting or
removing accessory boards.

5.2.2. TERMINAL BLOCK J2 (low voltage)
1& 5
=Common/Negative of accessory 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,
connect the N.O. contacts in parallel.
3 = STOP control device (N.C.)
Any control device (e.g. pushbutton) which, on
opening a contact, stops the movement of the gate.
T o install more than one Stop control de vice, connect
the N.C. contacts in series.
ÜIf 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,
magnetic loops) with an N.C. contact which
interrupts the movement of the gate when an
obstacle is detected 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 intervention of safety devices during gate
closure causes the direction of gate movement to
be reversed. These devices do not intervene during
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.
ÜIf no closure safety devices are to be installed,
place a jumper across this input and the commmon
terminal (terminal 1or5).

5.2.8. INDICATOR LEDS
5 LEDs on the board indicate the status of the terminal imputs:
LED
ON
= contact closed
LED
OFF
= contact open
To program the operation of the automation, set the dipswitches
as shown in the diagram above.
Ü Press the RESET button after all programming operations.
Operating logics
There are four operating logics available:
A1 = Automatic S1 = Safety
S2 = Safety Plus E = Semi-automatic
Operation of the different logics is described in tables 5-6-7-8.
Pause time
The pause time is amount of time the gate remains open before
it re-closes when an automatic control logic is selected.
Pause times include the pre-flashing time, if selected.
Warning light operation
Allows you to vary the flashing rate of the warning light during
gate closure.
Pre-flashing
It is possible to select 5 seconds pre-flashing of the flashing light
before any gate movement. This serves to warn any persons in
the vicinity that the gate is about to start moving.
