(1) The A/C input enables partial opening.
(2) With pre-flashing selected movement starts after 5
seconds.
(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.

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 MID-
TRAVEL 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.

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.
