Battery Powered Operation - Cardin Elettronica 200/BL3924ESB Instruction Manual

4) 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 gate leaf 1 manually. The
EMRG1 and 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 or right). The voltage at motor binding posts 1 and 2 has
the following polarity:
Command EMRG1: binding post 1 (+) binding post 2 (-)
Command EMRG2: binding post 1 (-) binding post 2 (+)
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. The electric lock (even if it
is enabled) is not active. Therefore if an electric lock is fitted it will have
to be activated manually.
After you have carried out an emergency manoeuvre the electronic programmer will
lose the position of the gate leaf (
operation is restored it will carry out a repositioning manoeuvre (see page 21).
LIMITED OPENING
This always effects gate 1; the limited opening space can be set (see display menu)
to 1/3, half, 2/3 or the entire opening distance for gate 1. The command can only
be carried out with both gates completely closed; if dip 1 is set to "OFF" and during
opening you activate the "TAL" command again gate leaf 1 will block and when it
receives the next command it will move in the closing direction. At this point the
command cannot be used again until complete closure.
COURTESY LIGHT /CH2 RADIO OUTPUT
Binding posts "9","10" are linked to a C-NO relay; this can be activated as follows.
• Jumper J5 in position 1: the contact is closed by a timer and works as a "courtesy
light"
• Jumper J5 in position 2: the contact works as a second radio channel.
Binding posts "9 ","10" only give a potential free contact; this means that the cour-
tesy light will have to be powered by an external circuit and the contact used as a
simple switch.

BATTERY POWERED OPERATION

This device allows the propulsion unit to work during blackouts.
• The programmer has a built in charger for NiMH 24V batteries that is managed
by a dedicated micro controller. The control chip adjusts the voltage according to
the condition of the batteries.
To avoid the risk of overheating only use batteries supplied by the
manufacturer SPN 999540.
If the batteries show signs of damage they must be replaced imme-
diately. 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 of according to the WEEE standards
and regulations in force.
• To indicate that the programmer is working off battery power when the door is
completely closed a hyphen flowing around the perimeter of the display will
appear.
If the battery is under charged a hyphen
display will appear. When the battery is almost completely flat the symbol
appear and the programmer will be blocked.
on the display) and therefore when normal
flowing around the lower half of the
• The unit returns to normal operation once the power supply brought back on line.
To use the batteries again they must first be allowed to recharge.
The battery charge time with batteries in good condition can take up to a maximum
of 12 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 door has stopped the controlled external devices (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 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
16-17 (fig. 12) otherwise a command sent via radio will not be able to activate the door.
• 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 16-17
(power is always routed there during blackouts).
When the batteries are completely flat (during blackouts) the program-
mer will lose the position of the door and therefore when power returns
(after the first command given) you will have to carry out the reposition-
ing procedure (see page 21). 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.
Signal LEDs (fig. 12)
L3: lit when the battery is not properly connected during blackouts.
L2: indicates the function mode as follows:
Off: missing batteries or the electronic programmer is running off battery power
(during a blackout). During the first 20 seconds of operation from the start up
of the electronic programmer the battery charger is blocked and will not supply
any function indications;
Brief flashing: voltage variation has been detected at the battery charger binding
posts (e.g. when the batteries are being connected or removed);
Single flashes: this repeats every 2 seconds indicating that the batteries are
being topped up to maintain their level;
Remains lit: the batteries are charging. The charge time can last from 5 to a
maximum of 12 hours.
Battery check
With the door in the completely closed position and the display switched off:
Check that LED "L2" (battery charging) is off;
Switch off the power at the mains and make sure that the symbol
display. Give a movement command and measure the overall voltage for both bat-
teries. The reading should be about 24 Vdc.
MAINTENANCE
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

- correct lubrication (greasing) of the moving parts.
