BATTERY POWERED OPERATION
• 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 immediately. 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 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
of the display will appear. When the battery is almost completely flat the symbol
will appear and the programmer will be blocked.
• 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 bat-
teries. 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. 2) 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 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 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.
Signal LEDs
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 program-
mer 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 or flashing;
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 batteries.
The reading should be about 24 Vdc.
MAINTENANCE
The motor does not normally require particular maintenance; in any case the 24 month
or 50.000 manoeuvre guarantee is only valid if the following controls have been observed
and eventual maintenance has been carried out to the machine "hinged gate":
- correct lubrication (greasing) of the moving parts.

System not programmed
You have to enter the programming mode to program the system
Out of position
When carrying out an installation you will have to enter programming
in order to program the gate travel distances.
During normal operation it indicates that the "repositioning" procedure
will take place when a (TA, TC, TAL or TD) is received (see page 17).
Block during encoder programming
This happens when an N.C. contact is activated (TB, FTCI, FTCS,
CSP) during encoder programming or repositioning. Once the pas-
sive state of the security devices has been reset the gate/door will
start moving again automatically. It also happens if a blackout occurs
during programming.
Safety device test error
Check the condition of the safety devices and make sure that
the alarm cuts in when an obstacle interferes with the beam (the
relative LED will switch off). In case of anomalies replace the
damaged safety device or bridge the contact and deactivate the
safety test (dip 7, 8).
Motor feed problems (M1, M2, M1 + M2).
This happens when the programmer sends a command to the motor but
nothing happens. Check the connections for each motor and the condition
of the fuses "F1" and "F2". Send another opening or closing command:
repositioning will be carried out (page 17); if the motor still doesn't work you
may have a mechanical or electronic problem.
Released motor (M1, M2)
This happens when there is a problem with the geared motor (drive shaft
disconnected from the gears).
Encoder error (ENC1, ENC2, ENC1 + ENC2)
If it occurs during normal motor operation it means that there is a problem
with one or more encoder signals. Check the relative connections and carry
out repositioning (page 15).
Current sensor error
When the gate is not moving this symbol means there is a problem with
the current sensor.
