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.
3) Manual manoeuvring with released motors
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 (after the motors
have been blocked again) automatic repositioning (according to ne-
cessity) will take place due to the positioning error.
Attention! If a command is given while the motor is re-
leased the symbol
4) Emergency manoeuvre
If the electronic programmer no longer responds to commands
due to a malfunction you may use the EMRG1 or EMRG2 inputs
to move the door manually. The EMRG1 or EMRG2 inputs directly
command the motor relays without passing through the logic con-
trol. The door will be moved at normal speed and the movement
direction will be as follows:
Command EMRG1: close
Command EMRG2: open
The inputs EMRG1: and EMRG2: are disabled by default: To en-
able them you must cut both contacts "EM" (see page 23)
Attention! during the emergency manoeuvre all safety
devices are disabled and there is no door positioning con-
trol: 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 the propulsion unit to work during blackouts.
• An optional battery charger for NiMH 24V batteries that is managed by
a dedicated micro controller can be inserted into the connector "C3".
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 999370.
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
local standards and regulations in force.
will appear on the display.
on the display)
• To indicate that the programmer is working off battery power when the
door is completely closed a hyphen
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 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 bat-
tery.
When a command is received however (via radio or via cable) the pro-
grammer 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 21 (fig. 6, 7) 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 21 (power is always routed there during blackouts).
When the batteries are completely flat (during blackouts) the
programmer 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 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.
• During blackouts the battery supplies power to both the logic and the
motor control parts of the programmer.
Signal LEds
L1 On the main board (fig. 31)
• Lit when the battery is not properly connected during blackouts.
L2 On the optional battery charger card.
• 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 elec-
tronic 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 "L10" (battery charging) flashes once;
Switch off the power at the mains and make sure that the symbol
on the display. Give a movement command and measure the overall voltage
for both batteries. The reading should be about 24 Vdc.
MAINTENANCE
To use the 24 month or 100000 manoeuvre guarantee, read the
following notes carefully.
The motor does not normally require particular maintenance; in any case
the 24 month or 100000 manoeuvre guarantee is only valid if the following
controls have been observed and eventual maintenance has been carried
out to the machine "garage door":
