6.3. LEARNING OF OPERATING TIMES
6. START-UP
6.1. LED CHECK
The board has a two-digit display. If out of the
"PROGRAMMING" mode, this display is used to indicate status
of inputs. Fig. 16 shows how the segments (we'll call these
LEDs from now on) of the display exactly correspond to the
inputs.
The table below shows the status of the LEDs in relation to to
the status of the inputs.
Note the following:
L
ED
LIGHTED
= closed contact
L
ED
OFF
= open contact
Check the state of the LEDs as per Table.
Operation of the status signalling LEDs
NB.:
The status of the LEDs while the gate is closed at rest are shown in bold.

OP_A Command activated Comando inattivo
OP_B Command activated Comando inattivo
STOP Command inactive Command activated
FSWCL Safety devices disengaged Safety devices engaged
FSWOP Safety devices disengaged Safety devices engaged
FCA1 (if used) Limit-switch free Limit-switch engaged
FCC1 (if used) Limit-switch free Limit-switch engaged
FCC2 (if used) Limit-switch free Limit-switch engaged
FCA2 (if used) Limit-switch free Limit-switch engaged
6.2. ROTATION DIRECTION AND FORCE CHECK
1) Program the functions of the 455 D control board according
to need, as shown in Chapter 5.
2) Cut power to the electronic control equipment.
3) Release the operators and manually move the gate to the
mid-point of the opening angle.
4) Re-lock the operators.
5) Restore power.
6) Send and opening command on the OPEN A input (fig.2)
and check if the gate leaves are being commanded to
open.
N.B.: If the first OPEN A pulse commands a closing, cut power
and change over the phases of the electric motor (brown
and black wires) on the 455 D terminal board.
7) Check power setting of the motors and, if necessary,
modify it (see Chapter 5.1).
N.B.:If using hydraulic operators, force should be programmed to
maximum level (50)
8) Stop leaf movement with a STOP command.
9) Release the operators, close the leaves and re-lock the
operators.
Opening/closing time is established by a learning procedure
which varies slightly according to whether you are using limit-
switches and/or Gatecoders.
6.3.1. LEARNING OF NORMAL TIMES
Normal learning (i.e. without limit-switches and Gatecoders)
can be done in two different ways:
- SIMPLE LEARNING (without deceleration):
Check if the leaves are closed, enter "
BASIC PROGRAMMING
",
select the TIME LEARNING function and press the + push-button
for 1 second: the display begins flashing and the leaves begin
the opening movement.
As soon as the leaves reach the opening contact point, give
an OPEN A pulse (with the key operated push-button or with
the radio control) to stop the movement: the leaves stop and
the display stops flashing.
Press push-button F to exit and save the programming.
The procedure has ended and the gate is ready to operate.
- COMPLETE LEARNING (with deceleration):
Check if the leaves are closed, enter "
BASIC PROGRAMMING
",
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 following functions can
be commanded by the OPEN A pulses (by key push-button or
radio control):
1° OPEN - Deceleration at opening of leaf 1
2° OPEN - Leaf 1 stops at opening and leaf 2 begins its
opening movement
3° OPEN - Deceleration at opening of leaf 2
4° OPEN - Leaf 2 stops at opening and immediately begins
its closing movement
5° OPEN - Deceleration at closing of leaf 2
6° OPEN - Leaf 2 stops at closing and leaf 1 begins its
closing movement
7° OPEN - Deceleration at closing of leaf 1
8° OPEN - Leaf 1 stops at closing
The display stops flashing: press push-button F to exit and save
the programming.
The procedure has finished and the gate is ready to operate.
Notes: •If you wish to eliminate deceleration in certain
stages, wait for the leaf to reach its stop-limit and
supply 2 consecutive Open pulses (by 1 second).
•If only one leaf is present, the entire sequence must
nevertheless be effected. When the leaf has finished
opening, supply 5 Open pulses until the leaf begins
to close, and then resume normal operation.
6.3.2. LEARNING WITH LIMIT-SWITCHES
Learning with limit-switches can be done in two different ways:
- SIMPLE LEARNING (without deceleration):
Check if the leaves are closed, enter "
BASIC PROGRAMMING
",
select the TIME LEARNING function and press the + push-button
for 1 second: the display begins flashing and the leaves begin
the opening movement.
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 has finished and the gate is ready to operate.
- COMPLETE LEARNING (with deceleration):
Check if the leaves are closed, enter "BASIC PROGRAMMING",
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.
WARNING:
during the learning procedure, the safety devices are disabled!
Therefore any transit must be avoided in the leaf movement
area when this operation is carried out.
Make sure the travel limit mechanical stops are present.
