(
CTRL 30 Vdc) do not receive power in order to increase the
autonomy of the battery. When a command is received however (via
radio or via cable) the programmer sends power to the controlled
external devices and checks their security status. It follows therefore
that the command will be carried out (security devices at rest) with
a one second delay to give time to restore the correct operation of
the devices.
If after this period a security device is found to be in alarm the com-
mand will not be carried out, power to the external devices will be
cut off and the programmer will return to stand-by.
Note! If you wish to use an external receiver it must be wired to the
binding posts 17-18 (fig. 3) otherwise a command sent via radio will
not be able to activate the gate.
• The self-sufficiency of the system when it is running on battery power
is dependent on the ambient conditions and on the load connected
at binding posts 17-18 (power is always routed there during black-
outs).
When the batteries are completely flat (during blackouts) the
programmer will lose the position of the gate and therefore
when power returns carry out the repositioning procedure
(see pag. 19). For this reason you should
avoid leaving the
electronic programmer without power for lengthy periods
(more than two days).
• You cannot enter the programming mode when running off battery
power.
• During blackouts the battery supplies power to both the logic and
the motor control parts of the programmer. For this reason during
battery powered operation the voltage supplied to the motor is less
than that normally applied and the motor will move more slowly.
Signal LEDs (fig. 3)
L2: lit when the battery is not properly connected during blackouts.
L4 lit when the current supplied by the battery charger is greater than
the battery maintenance level (about
50 mA).
If the batteries are damaged they could leak acid.
The batteries must only be installed/removed by qualified
personnel. Used batteries must not be thrown into domestic
rubbish bins and they must be disposed according to the
local standards and regulations in force.
battery check
Move the gate to the completely closed position and the display will
switch off. Check that LED "
L4" (battery charging) is off.
Switch off the power at the mains and make sure that the symbol
appears on the display. Give a movement command and measure
the overall voltage for both batteries. The reading should be about
22 Vdc.
To use the
24 month or 100000 manoeuvre guarantee,
read the following notes carefully.
The motor does not normally require particular maintenance; in any
case the
24 month or 100000 manoeuvre guarantee is only valid
if the following controls have been observed and eventual mainte-
nance has been carried out to the machine "sliding gate":
- correct lubrication (greasing) of the toothed rack;
- check the straightness of the toothed rack, make sure the teeth
fit correctly in the pinion throughout its entire length; in particular
the toothed rack must have a cross section of
20 x 20 mm (see
accessories on page 14);
- check the play of the toothed rack - pinion (
1-2 mm see fig. 6);
- check the battery charge level.
These checks must be written down as they are paramount in
validating the guarantee.
3) Manual manoeuvre with the motor released
Releasing the motor (see fig. 8) the gate can be moved by hand. The
electronic programmer will still monitor the position of the gate.
Attention! If a command is given while the motor is released
the symbol
will appear on the display. The reposition-
ing procedure will have to be carried out.
4) Emergency manoeuvre
If the electronic programmer no longer responds to commands due to
a malfunction you may use the
EMRG1 or EMRG2 inputs to move the
gate leaf manually. The
EMRG1 or EMRG2 inputs directly command
the motor relays without passing through the logic control.
Gate movement will be at reduced speed and the direction depends
on the installed position of the motor:
- left-hand installed motor
EMRG1 opens and EMRG2 closes;
- right-hand installed motor
EMRG1 closes and EMRG2 opens.
Attention! During the emergency manoeuvre all safety
devices are disabled and there is no gate positioning control:
release the commands before you are at the mechanical
travel buffer. Only use the emergency manoeuvre in cases
of extreme necessity.
After you have carried out an emergency manoeuvre the electronic pro-
grammer will lose the position of the gate leaf (
on the display) and
therefore when normal operation is restored it will carry out an automatic
repositioning manoeuvre (see pag. 19).
The management of the limited opening command "
TAL" is similar to
the "
TD" command.
• If the "open-close" mode is set for the "
TD" button (dip 1 "ON")
activating the "
TAL" button will start the limited opening stage (only
from the completely closed position) but while the gate is opening
pressing the button again will have no effect. Once the opening posi-
tion has been reached pressing the "
TAL" button will start closing
after which pressing "
TAL" again will have no effect.
• If the "open-block-close" mode is set for the "
TD" button (dip 1 "OFF")
activating the "
TAL" button will start the limited opening stage (only
from the completely closed position) pressing the button again will
block the gate; pressing the button a third time will start the closing
cycle. Pressing the "
TAL" button again will have no effect.
• If an opening command is received during limited opening; the limited
opening command will become a full opening command.
If the
FTCI photocell cuts in during the closing stage you will only
have partial movement in the opening direction.
•
Note: The limited opening command can also be given using the
second channel radio function.
The limited opening distance is set to half of the entire opening
distance.
This device allows the
SL424EbSS motor for sliding gates to work
during blackouts.
• To indicate that the programmer is working off battery power when the
gate is completely closed a hyphen flowing around the perimeter
of the display will appear.
If the battery is under charged a hyphen flowing around the lower
half of the display will appear. When the battery is almost completely
flat the symbol will appear on the display and the motor and com-
mands will be blocked.
• Normal operation can only be obtained when the power has been
restored. To operate using battery power again the batteries will
need time to recharge. The battery charge time with batteries in
good condition can take up to a maximum of
15 hours. If the time
required is greater you should consider replacing the batteries. You
are however advised to replace the batteries every three years.
• When the gate is completely closed the controlled external devices
