Battery Powered Operation; Maintenance - Cardin Elettronica SL-Serie Anleitung

5) Emergency manoeuvre
If the electronic programmer no longer responds to commands due to a malfunc-
tion 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 closes and EMRG2 opens;
- 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. 19).

bATTERY POWERED OPERATION

This device allows the SL1524 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
half of the display will appear. When the battery is almost completely flat the
symbol will appear and the programmer will be blocked.
• After 15 manoeuvres or when the battery power drops below the minimum
level the gate will remain completely open even if automatic reclosing has been
selected.
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
30 dc) 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 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 4-5
(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 depend-
ent on the ambient conditions and on the load connected at binding posts 4-5
(power is always routed there during blackouts).
When the batteries are completely flat (during blackouts) the program-
mer 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 opera-
tion the voltage supplied to the motor is less than that normally applied and the
motor will move more slowly.
• The current sensor is disabled when battery power falls below the minimum
level , but all other safety devices are still functional.

on the display) and therefore when
flowing around the lower
The wires connecting the battery to the charger card must never be
short-circuited, this would damage the battery, and in the worst of
cases could lead to burns (if metal parts are touching the skin when
the contact is made). Only connect them to the Faston (CN3) and
make sure you respect the polarity. 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

batteries. The reading should be about 22 Vdc.

MAINTENANCE

To use the 24 month or 50000 manoeuvre guarantee, read the fol-
lowing 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 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.
