Connecting OVO to the mains
CAUTION!
- Never cut or remove the cable supplied with OVO.
- If not already available, a power socket for connecting OVO
to the mains must be made by qualified and experienced per-
sonnel in strict observance of current legislation, standards
and regulations.
OVO must be connected to the supply mains by a qualified
electrician.
To test OVO, just insert the plug into a power outlet, using an exten-
sion cord if necessary (fig. 28).

Preliminary checks
As soon as OVO is energised, you should check the following:
01. Check that the LED [U] is flashing normally with around 1 flash
per second (fig. 29).

3.7.1 - Recognition of the door opening and
closing positions
The control unit must be made to recognise the opening and closing
positions of the door. In this phase, the door stroke from the clos-
ing mechanical stop to the opening mechanical stop is detected. In
addition to position, the STOP input configuration is detected and
memorised in this phase as well as the existence or non-existence of
the PHOTO input "Phototest".
01. Ensure that the drive belt is correctly tensioned and that the two
mechanical stops are fully secured.
02. Engage the carriage.
03. Press the P2 and P3 keys and hold them down (fig. 30).
04. Release the keys when the manoeuvre starts (after approx. 3 s).
05. Wait for the control unit to complete the recognition stage: clos-
ing, opening and closing again of the door.
06. Push the P3 key to perform a complete opening manoeuvre.
07. Push the P3 key to close.
During these manoeuvres, the control unit memorises the force re-
quired for opening and closing.
If the L2 and L3 LEDs flash at the conclusion of the recognition pro-
cess, it means that an error has occurred; see section 8 ("Trouble-
shooting").
Important! - It is important that these manoeuvres are not interrupt-
ed, e.g. by a STOP command. If this occurs, the recognition process
described in point 01 must be repeated.
The recognition stage of the positions, and of the STOP and PHOTO
input configuration, can be repeated again at any time, even after the
installation (for example, if one of the mechanical stops is removed);
just repeat the procedure starting from step 01.
30
CAUTION! During the position search process, if the belt
is not sufficiently tensioned, it may slip on the pinion. If this
occurs, press the P2 key to interrupt recognition; tension the
belt by tightening the M8 nut (F) as shown in fig. 31, then re-
peat the recognition process from point 01.
31
Recognition of the door opening and closing positions is only
possible after the radio transmitter memorisation and deletion
time interval has elapsed (see section 3.7.5 "Radio receiver").
3.7.2 - Checking door movements
Once the opening and closing positions have been recognised, it is
advisable to carry out a number of manoeuvres in order to check the
door travels properly.
01. Press the P3 key to open the door. Check that the door opens
normally, without any variations in speed; the door must only slow
down and stop when it is close to the opening mechanical stop.
02. Press the P3 key to close the door. Check that the door closes
normally, without any variations in speed; the door must begin the
slow down when it is between 30 and 20 cm. from the closing me-
chanical stop, and then stop. A brief opening manoeuvre is then per-
formed to release belt tension.
03. During the manoeuvre, check that the flashing light (if any) flashes
at a speed of 0.5 seconds on and 0.5 seconds off.
04. Open and close the gate several times to make sure that there
are no points of excessive friction and that there are no defects in the
assembly or adjustments.
05. Check that the fastening of the gearmotor, the guide and the
mechanical stops are solid, stable and suitably resistant, even if the
