Scheda carica batteria
This device allows the propulsion unit to work during blackouts.
• The programmer has a built in charger for an
NiMH 24V
battery that is
managed by a dedicated micro controller. The control chip adjusts the
voltage according to the condition of the connected battery.
To avoid the risk of overheating only use the battery supplied
by the manufacturer (
SPN
999540
).
If the battery shows signs of damage it must be replaced
immediately.
The battery 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
local standards and regulations in force.
• The unit returns to normal operation once the power supply brought back
on line. To use the battery again it must first be allowed to recharge.
The battery charge time with a battery in good condition can take up
to a maximum of
16 hours
. If the time required is greater you should
consider replacing the battery. You are however advised to replace the
battery every three years.
• When the door has stopped, the controlled external devices (
CTRL 24
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 16-17 (fig. 1) 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 dependent on the ambient conditions and on the load connected at
binding posts 16-17 (power is always routed there during blackouts).
When the battery is completely flat (during blackouts) the pro-
grammer will lose the position of the door and therefore when
power returns (after the first command given) you will have to
carry out the repositioning procedure (see page 20). For this
reason you should avoid leaving the
electronic programmer
without power
for lengthy periods (more than two days).
• It is not possible to 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 applied
to the motor is inferior to the voltage supplied during normal operation
and the motor will therefore work slower and will not decelerate when
ªapproaching the travel limits.
Slot-in battery charger
The LED
L3
indicates the function mode as follows:
Off
: missing batteries or the electronic programmer is run-
ning off battery power (during a blackout). During the
first 10 seconds of operation from the start up of the
electronic programmer the battery charger is blocked.
After this period has elapsed it may either start self-
diagnostics (indicated by a lengthy flashing of the Led)
or it will start recharging (Led continuously lit);
Brief flashing:
voltage variation has been detected at the battery
charger binding posts (e.g. when the batteries are
being connected or removed);
Single flashing:
this repeats every 2 seconds indicating that the bat-
teries are being topped up to maintain their level;
Remains lit:
the batteries are charging. The charge time depends on
a number of factors and can last up to 16 hours. Using
the motor will increase the time needed for charging.
Battery check
With the gate in the completely closed position and the display switched off.
Check that LED "
L3
" (battery charging) is giving off
"one flash at a time"
.
Switch off the power at the mains and make sure that the display indicates
that it is working off battery power and that it is fully charged
. Give a
movement command and measure the overall voltage. The reading should
be at least
22 Vdc
.
