03. Press the P3 key to move the flashing LED to the "input LED" associated with the parameter to be modified.
04. Press and hold P2during steps 5 and 6.
05. Wait approx. 3s, after which the LED associated with the current level of the parameter to be modified will light up.
06. Press the P3 key to move the LED associated with the parameter value.
07. Release P2.
08. Wait 10s to exit the programming mode automatically after the maximum time interval.
Points 3 to 7 can be repeated during the same programming phase to modify other parameters.

Adding or removing devices
Devices can be added or removed at any time on an automation us-
ing OVO. In particular, various types of device can be connected to
the inputs STOP and PHOTO as indicated in sections 4.8.1 ("STOP
Input") and 4.8.2 ("Photocells"). Fig. 39 shows the wiring diagram for
connecting the various devices.

7.3.1 - STOP input
STOP is the input that stops movement immediately, followed by a
brief reverse of the manoeuvre. Devices with contact types Normally
Open (NO), Normally Closed (NC) or devices with a constant resist-
ance of 8.2.2KΩ (such as safety edges) can be connected to this
input.
The control unit recognises the type of device connected to the
STOP input during the recognition phase (see section 3.7.1 "Recog-
nition of the door opening and closing positions"); after this, a STOP
command is activated whenever the device detects any difference
from the recognised setting.
When set accordingly, more than one device (these can be different)
can be connected to the STOP input:
• An unlimited number of NO devices can be connected in parallel.
• An unlimited number of NC devices can be connected in series.
• Several devices with a constant resistance of 8.2 KΩ can be "cas-
cade" connected with a single terminating resistance of 8.2 KΩ
• It is possible to combine two NO and NC contacts, placing them
in parallel, taking care to place a resistance of 8.2 KΩ in series with
the NC contact (this also enables the combination of 3 devices: NO,
NC and 8.2 KΩ).
If the STOP input is used for connecting devices with safety func-
tions, only the devices with a constant resistance of 8.2 KΩ guaran-
tee safety category 3 against faults in accordance with the standard
EN 954-1.
7.3.2 - Photocells
Please note - The images in this section refer to the Viky 30 photo-
cell model.
The OVO control unit is equipped with a "Phototest" function which
increases the reliability of the safety devices, enabling it to be classi-
fied in category 2 in compliance with the standard EN 954-1 regard-
ing the combination of the control unit and safety photocells.
Each time a manoeuvre is started up, all safety devices are checked
and operation will only start if everything is in order. If, however, the
test fails (photocell "blinded" by the sun, cables shorted etc.), the
fault is identified and the manoeuvre disabled.
For the "phototest" function, a specific connection is required for the
photocell transmitters (see fig. 42 and 43). The control unit recog-
nises the connection in "phototest" mode during the self-learning
phase (see section 3.7.1 "Recognition of the door opening and clos-
ing positions").
• Connection without "Phototest" function (fig. 40 and 41)
Power the transmitters and receivers directly from the control unit
services output (terminals 3 - 6).

• Connection with "Phototest" function (fig. 42 and 43)
The receiver power comes directly from the services output (termi-
nals 3 - 6), while that of the transmitters is from the "Phototest" out-
put (terminals 8 – 6). The maximum admissible current on the "Pho-
totest" output is 100 mA.
