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/door.
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:
- for a left-hand installed motor EMRG1 closes and EMRG2 opens;
- for a right-hand installed motor EMRG1 opens and EMRG2 closes.
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 programmer
will lose the position of the gate leaf (
normal operation is restored it will carry out an automatic repositioning manoeuvre
(see pag. 17).
LIMITED OPENING (PEDESTRIAN ACCESS)
The management of the limited opening command "TAL" (or the second radio
channel) is similar to the "TD" command.
• If the "open-close" mode is set for the "TD" button (programming step 1;
number "1" fixed) activating the "TAL" button will start the limited opening
stage (only from the completely closed position) but while the gate is open-
ing 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 (programming
step 1; number "1" flashing) activating the "TAL" button will start the lim-
ited 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.
BATTERY POWERED OPERATION
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
display will appear.
If the battery is under charged a hyphen
of the display will appear. When the battery is almost completely flat the
symbol will appear and the programmer 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 (CTRL
30dc) 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
on the display) and therefore when
flowing around the perimeter of the
flowing around the lower half
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. 9) 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/door and there-
fore when power returns carry out the repositioning procedure
(see pag.17). 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. 9)
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
on the display. Give a movement command and measure the overall voltage
for both batteries. The reading should be about 22 Vdc.
MAINTENANCE
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 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 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 12);
- 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.
