If two pairs of photocells are used which could interfere with each
other, activate the synchronisation mechanism as described in the
photocell instructions.

7.3.3 - Electric lock

The factory setting of the "phototest" output is with the "Phototest"
function enabled.
Alternatively, the output can be programmed on the OVO control unit
to control an electric lock. On start-up of each opening manoeuvre,
the output is activated for 2 seconds; in this way an electric lock de-
vice can be connected. The output is not activated during the closing
manoeuvre and therefore the electric lock must have a provision for
mechanical reactivation.
The output cannot control the electric lock directly (only loads of
24Vac – 2W). The output must be interfaced with a relay, as shown
in fig. 44.

Special functions

7.4.1 - "Always open" function

The "Always open" function is a control unit feature which enables
the user to control an opening manoeuvre when the "Step-by-step"
command lasts longer than 3 seconds. This is useful for connecting
a timer contact to the "Step-by-step" input in order to keep the door
open for a certain length of time, for example.
This feature is valid whatever the "Step-by-step" input programming
may be (see the "Step-by-step" properties in table 12).

Connection of other devices

If the user needs to power external devices, it is possible to tap pow-
er as shown in fig. 45. The power supply voltage is 24Vac -30% ÷
+50% with a maximum available current of 100mA.
