5.1. CONNECTION TO ELECTRONIC CONTROL UNIT

Warning: Always turn off the electricity supply before
carrying out any work on the electronic control unit
(connections, programming, maintenance).
Warning: When terminal board J2 is disconnected, high
voltage remains on the outputs of the capacitor, motor and
transformer power supplies.

Observe points 10, 11, 12, 13 and 14 in the GENERAL SAFETY
INSTRUCTIONS.
As shown in Fig. 2, prepare the conduits and make the
electrical connections from the 826 MPS electronic control
unit to the chosen accessories.

5.2. DESCRIPTION OF TERMINAL BLOCK

5.2.1. OPEN (terminals 1-2)

This means any control device with a N.O. contact which
causes the gate to open when activated. In automatic
and semiautomatic logics it is active for both opening and
closure.

5.2.2. A/C (terminals 1-3)

This means any control device with a N.O. contact which
causes partial opening of the gate when activated in E1,
E2, A1, A2, S1 and S2 logics. In B and C logics it causes the
gate to close.

5.2.3. STOP (terminals 1-4)

This means a control device with a N.C. contact which
causes the gate status (opening-pause-closure) to be
interrupted until the next impulse is sent.

N.B.: If stop devices are not connected, jumper terminals 1-4.

5.2.4. SAFETY FX (terminals 5 - 6)

This means all devices (photocells, safety edges, magnetic
loops) with a N.C. contact which stop the movement of
the gate when an obstacle is present in the area protected
by the safety devices.

N.B.: If stop devices are not connected, jumper terminals 5-6.

5.2.5. + - LOW VOLTAGE POWER SUPPLY (terminals 6 - 7)

These are the 24 Vdc terminals to which the accessories
must be connected.
Proceed as shown in Table 3 in order not to exceed the
maximum permitted load.

5.2.6. LAMP (terminals 8 - 9 - 10)

These are the 24 Vac terminals to which the warning lamp
must be connected.
Warning lamp operation illustrated in Fig. 24 refers to
connection to terminals 8-9. Connecting the warning
lamp to terminals 8-10 gives inverse operation.

5.2.7. FAAC LAMP (terminals 11 - 12)

These are the 230 Vac terminals to which the flashing light
must be connected.

5.2.8. 230 V MAINS SUPPLY (terminals 13 - 14)

These are the terminals to which the 230 Vac electricity
supply must be connected.
Connect the earth cable to the post as shown in Fig. 23b.

5.2.9. BEHAVIOUR OF SAFETY DEVICES

The safety devices operate during closure only. In A1, E1
and S1 logics, interrupting the safety device contacts causes
the gate to stop closing and start opening immediately. In

18

ENGLISH

Fig. 23b

A2, E2 and S2 logics interrupting the safety device contacts
causes the gate to stop closing, then to start opening again
when the safety devices are released.

5.2.10. ELECTRONIC SAFETY DEVICE

(models 820 EMC - 860 EMC only)
The operator is equipped with a system which cuts in when
it senses a 20% reduction in pinion speed. The device inverts
the closing movement and inhibits opening movement.
When this safety device cuts in, LED S goes out for a few
seconds. Automatic re-closure is inhibited if the electronic
anti-crushing safety has cut in.

(3) If the impulse is sent after pre-flashing the timer recounts.
(4) For operation in C logic keep the pushbutton depressed.

Movement stops upon release.
(5) The A/C input controls closure.

5.5. PROGRAMMING LIMIT SWITCHES

IMPORTANT: CHECK THE LENGTH OF THE GATE. THE

OPERATOR HAS A LIMIT SWITCH SYSTEM WHICH ALLOWS
FOR AUTOMATION OF GATES WITH A MAXIMUM LENGTH OF
13 m FOR MODELS 820 (Z 20 PINION) AND 10 m FOR
MODELS 860 (Z 16 PINION).

FAILURE TO OBSERVE THESE RECOMMENDATIONS WILL
ADVERSELY AFFECT OPERATION OF THE ADL LIMIT SWITCH.

1) To facilitate installation, it is advisable to program the

control unit in E1 logic (semi-automatic) by positioning

the relative dipswitches as follows:

SW1 - SW2 - SW3 to ON.

It is also advisable to inhibit pre-flashing by positioning
dipswitch SW7 to OFF.

7) Without moving the gate carry out the following
operations on the 826 MPS control unit (Fig. 27) in the
stated order:

a) hold down FCA.
b) press the RESET button for about 1 second. The ADL

LED will light up for approximately one second to
confirm that the limit switch has been recognised.

c) release the FCA button.

2) Position dipswitch SW8 according to the direction in
which the gate closes (see Fig. 25) (Rack application).

IMPORTANT: In chain applications the dipswitch SW8 must
be positioned to ON for closure to left and OFF for closure
to right.

The positions of dipswitches SW4, SW5 and SW6 have no
effect.

3) Move the gate manually to its mid-travel position.

4) Switch on the electricity supply to the system and
check that the status of the LEDs is as follows:

LED ON LED OFF

ADL - FCA - FCC OPEN - A/C -

S (860) - STOP - FSW S (820)

IMPORTANT: MAKE SURE THAT THE GATE IS AT ITS MID­TRAVEL POSITION.

5) Remove the safety tab as illustrated in Fig. 26 and keep
it for future maintenance work.

6) Open the gate until it is just a few centimetres away
from the open position end stop.

Fig. 27

8) Wait for a few seconds, then slide the gate manually
until it is a few centimetres from the closed position end
stop.

9) Without moving the gate carry out the following
operations on the 826 MPS control unit (fig. 27) in the
stated order:
a) hold down FCC.
b) press the RESET button for about 1 second. The ADL

LED will light up for approximately one second to
confirm that the limit switch has been recognised.

c) release the FCC button.

10)Re-engage the operator by sliding the gate until the
release device engages.

11)Send an open impulse and check that the gate opens,
performs a brief deceleration, then stops at the
programmed open position limit switch.

12)Send another impulse and check that the gate closes.

13)To modify limit switch settings, repeat the sequence of
operations from point 3) to point 12).

IMPORTANT: If the LED starts flashing quickly (0.25 s) during
the limit switch setting operations, follow the instructions
given in the ALARM CONDITIONS section.

N.B.: Any interruption in the power supply will not affect
memorisation of the limit switch positions.

If during a manual operation the gate is moved beyond
the memorised limit switch positions, a series of open
impulses must be sent to move the gear motor to the zone
of normal operation.
