2.5 Adjusting the limit switches
The limit switch adjustment is carried out as follows:
1. Unscrew the upper fastening screw, Fig.18 Ref.1, and
remove the cap, Fig.18 Ref.2.
2. To adjust the closing limit switch FCC, turn the adjusting
screw clockwise (Fig.19 Ref. 1) to increase rod stroke
and counter-clockwise to reduce it.
3. To adjust the opening limit switch FCA, turn the adjust-
ing screw counter-clockwise (Fig. 20 Ref. 1) to increase
rod stroke and clockwise to reduce it.
4. Perform a couple of test cycles to check the correct posi-
tion of the limit switch. If the limit switch needs additional
adjustment, repeat the operation starting from Step 2.
5. As you manually move the gate the limit lights on
the control board turn off when they are triggered.
FCA - open limit; FCC - close limit
6. Reposition the cap (Fig. 18 Ref. 2) and tighten the fasten-
ing screw (Fig. 18 Ref. 1)

2.6 Time Learning with limit switches
NOTE: The time learning procedure explained in par. 10 of the
455D control board section of the manual is different for the
415 operator, due to the presence of the limit switches. Read
below for the specific instructions.
Learning with limit-switches can be done in two different ways:
SIMPLE LEARNING (without slow-down):
Check that the leaves are closed, enter "BASIC PROGRAM-
MING", select the TIME LEARNING function and press the +
push-button for 1 second: the display begins flashing and the
leaves begin to open.
The motors stop automatically when the opening limit-switches
are reached, but an OPEN A pulse must be given (by radio
control or key push-button) to end the cycle.
The display stops flashing: press push-button F to exit and save
the programming. The procedure is finished and the gate is
ready to operate.
COMPLETE LEARNING (with slow-down):
Check that the leaves are closed, enter "BASIC PROGRAM-
MING", select the TIME LEARNING function and press the +
push-button for more than 3 seconds: the display begins
flashing and leaf 1 begins the opening movement.
The leaves automatically decelerate when they reach the limit
switches, then the control board needs to receive a pulse on
the OPEN A input (by radio control or key push-button) when
the stop limits have been reached to turn off the motor.
When gate operator (1) reaches the open limit-switch, it starts
to slow down. When operator (1) reaches its positive stop an
open command must be given to shut the motor off.
• After the gate operator (1) has reached its positive stop and
has shut off, gate operator (2) will automatically start to open
• When gate operator (2) reaches the open limit-switch, it
starts to slow down. When operator (2) reaches its positive stop
an open command must be give to shut the motor off.
• After operator’s (2) motor shuts off it will automatically start to
close.
• When gate operator (2) reaches the closed limit-switch, it
starts to slow down. When operator (2) reaches its positive stop
an open command must be given to shut the motor off.
• When operator (2) reaches its positive stops and the motor
shuts off, gate operator (1) will start to close automatically.
• When gate operator (1) reaches the closed limit-switch, It
starts to slow down. When operator (1) reaches its positive stop
an open command must be give to shut the motor off.
The display will stops flashing. Press the “F” button one last time
to return to the status display and the gate is ready for normal
operation.
