GENERAL FUNCTIONS
L4
RESTORING MANOEUVRE
WITH DEAD MAN FUNCTION
MINIMUM:
n
MAXIMUM:
y
This function, if enabled,
L4
=
Y
allows the gate to be opened or closed if one of the safety devices (photocells or stop) breaks down,
allowing passage until the fault is repaired. This mode requires the installation of a START device (normally open contact) on terminal block
9 or terminal block 10 and the setting of its management parameter (
e1
or
e2
) to one of the following functions:
go
start,
op
open or
cL
close. If the conditions described above are met and a safety device (stop, external or internal photocell) has been active for more than
5 seconds, then it is possible to operate the gate in opening/closing mode using this procedure:
1. Activate the START device
2. Deactivate the START device
The flashing lights turn on (only if configured on terminals 20 + e 21 - (
L0
) via function
L0
=
02
or
L0
=
03
).
3. Activate the START device within 2.5 seconds of the flashing light coming on. The control unit shows the countdown from 2.5 to 0 sec-
onds on the display.
4. The gate will perform the required operation (opening/closing) as long as the START device is kept active. When the START device is
deactivated, the control unit blocks the movement of the gate.
L5
WORKING CYCLES LIMIT - MAINTENANCE
REQUEST
MINIMUM:
n
MAXIMUM:
5.9
Parameter
L5
allows the number of working cycles before maintenance to be set. When the gate has performed
L5
operation, the time
for flashing will be set to 5 seconds. This function can be useful for alerting the end user to the need for system maintenance. The parameter
L5
can be set in these ranges:
n
= disabled
- from
0.1
to
0.9
from 1 to 9 working cycles
- from
1.1
to
1.9
from 10 to 90 working cycles
- from
2.1
to
2.9
from 100 to 900 working cycles
- from
3.1
to
3.9
from 1000 to 9000 working cycles
- from
4.1
to
4.9
from 10000 to 90000 working cycles
- from
5.1
to
5.9
from 100 000 to 900 000 working cycles
Pressing any key on the control unit sets the counter to 0 and this function will only be activated again after
L5
cycles.
L6
WORKING CYCLES COUNTER
MINIMUM:
0.1
MAXIMUM:
6.9
Parameter
L6
cannot be changed or deleted and represents the number of working cycles of the automatic gate. Once the parameter
L6
has been selected (see the MENU NAVIGATION page) the most significant decimal number of the counter is shown in the format
POSITION, VALUE. By pressing the (
-
) KEY the display switches off.
Once the (
-
) KEY is released the scanning of the counter begins displaying its
decimal position (value to the left of the dot) and its value (to the right of the dot).
EXAMPLE:
if a gate has performed 6258 operations, once
L6
has been selected the display shows:
3.6
by pressing the (
-
) KEY the display switches
off. By releasing the (
-
) KEY the display will show in sequence:
multiplier:
*1000
*100
*10
*1
position:
3
2
1
0
3.6
2.2
1.5
0.8
value:
6
2
5
8
= 1000*6 + 100*2 + 10*5 + 1*8
The display changes screen to the next position approximately every 3 seconds, switching off briefly before showing the new number.
How to read the display:
the first digit indicates the exponent of the
power of 10, the second its multiplier.
For example:
3.3 indicates 103 x 3 = 3,000
2.9 indicates 103 x 9 = 900
5.1 indicates 105 x 1 = 100,000
