9.1.3 Electric lock
The PHOTOTEST output is by default enabled for the PHOTOTEST
function, but can be programmed for controlling an electric lock
(see the “Setting the PHOTOTEST operation” chapter on page
20).
At the start of the opening movement, the output is activated for
2 seconds, while during the closing manoeuvre it is not activated,
therefore the electric lock must reset mechanically.
The output cannot control the electric lock directly, but only loads
of 24 V c 3 W.
The output must be interfaced with a relay, as shown in the gure.

2. pull the cover (B) slightly outwards and turn it downwards
