4) Emergency manoeuvre
If the electronic programmer no longer responds to commands due to a
malfunction you may use the
EMRG
or
EMRG2
inputs to move gate leaf
1 manually. The
EMRG
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
EMRG
: 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 program-
mer will lose the position of the gate leaf (
on the display) and therefore
when normal operation is restored it will carry out an automatic 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 com-
mand 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
”,”
0
” 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
”,”
0
” only give a potential free contact; this means that the
courtesy light will have to be powered by an external circuit and the contact
used as a simple switch.
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 999506
.
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.
• 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 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
2 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 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
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 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
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 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. 2)
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 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 depends on
a number of factors and can last from 8 to a maximum of 12 hours. If
you use the motors during this period the charge time will increase.
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 appears
on the display. Give a movement command and measure the overall voltage
for both batteries. The reading should be about
22 Vdc
.
To use the
24 month
or
00000
manoeuvre guarantee, read the
following notes carefully.
The motor does not normally require particular maintenance; in any case
the
24 month
or
00000
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.
