• When the gate is completely closed the controlled external devices (
CTRL
30 Vdc) do not receive power in order to increase the autonomy of the bat-
tery.
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 command
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 blackouts).
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 program-
mer 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 person-
nel. 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 50000 manoeuvre guarantee, read the
following notes carefully.
The motor does not normally require particular maintenance; in any case
the
24 month or 50000 manoeuvre guarantee is only valid if the following
controls have been observed and eventual maintenance 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 cor-
rectly 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 repositioning
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 com-
mands 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 program-
mer 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 position 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 commands 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.
