2) Semiautomatic
Selected by deactivating automatic reclosing (dip "2" in position
"OFF"). Work cycle control using separate opening and closing
commands. When the door has reached the completely open
position the system will wait until it receives a closing command
either via an external control button or via radio control, before
completing the cycle. The indicator light remains lit until the clos-
ing manoeuvre has terminated.
3) Manual manoeuvring with released motor
Releasing the motors the door can be moved by hand; in this
stage the programmer does not control the position of the door
leaves and so when the next movement command is given (af-
ter the motors have been blocked again) automatic reposition-
ing (according to necessity) will take place due to the position-
ing error.
Attention! If a command is given while the motor is
released the symbol
4) Emergency manoeuvre
If the electronic programmer no longer responds to com-
mands due to a malfunction you may use the EMRG or
EMRG2 inputs to move the door manually. The EMRG or
EMRG2 inputs directly command the motor relays without
passing through the logic control.
The door will be moved at normal speed and the movement
direction will be as follows:
Command EMRG: close
Command EMRG2: open
Attention! During the emergency manoeuvre all safety
devices are disabled and there is no door positioning
control: release the commands 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 door (
and therefore when normal operation is restored it will carry out
an automatic repositioning manoeuvre (see page 24).
BATTERY POWEREd OPERATION (OPTIONAL)
This device allows devices connected to the electronic control
unit to work during blackouts.
• 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 flowing around the lower half of the dis-
play will appear. When the battery is almost completely flat the
symbol will appear and the programmer will be blocked.
• When the door is completely closed 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 post 13 (pages 8,9) 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 post 13 on pages 8,9 (power is always
routed there during blackouts).
will appear on the display.
on the display)
• 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 batteries are completely flat (during black-
outs) the programmer will lose the position of the
door and therefore when power returns (after the first
command given) it will carry out the repositioning pro-
cedure (see page 24). 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.
Signal LEds (pages 8, 9)
L2: lit when the battery is not properly connected during black-
outs.
L3: lit when the current supplied by the battery charger is greater
than the battery maintenance level (about 50 mA).
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 decicated
binding posts (7, 8) 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 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
With the door in the completely closed position and the display
switched off:
Check that LED "L3" (battery charging) is off;
Switch off the power at the mains and make sure that the
symbol appears on the display. Give a movement command
and measure the overall voltage for both batteries. The reading
should be about 22 Vdc.
