V2 ELETTRONICA City1 Manual De Instrucciones página 43

WARNING: This function is active in case the ends of stroke have been fitted and enabled and if the START IN OPENING has
been disabled.
WARNING: any improper use of this function may jeopardize the gate safe use. V2 recommends what follows:
• Make use of this function only in case the door passage before the photocells is actually unavoidable.
• Set up the shadow zone limits as tight as possible, complying with the necessary margins to compensate any possible door speed
difference.
Photocell 2 Shadow Zone
In some installations it may occur that the gate door
passes before the photocells, so breaking their beam.
In this case, the gate cannot complete its closing cycle.
Through this function, photocells can be temporarily
disabled, so allowing the door passage. Only those
photocells which are connected to the Photocell type 2
input can be disabled, this function being therefore
activated in the closing phase only.
The door travel, during which photocells are not active,
is measured in seconds from the beginning of the door
1 closing and starting from the max. opening position.
Please comply with the following procedure to setup the
shadow zone limits:
• Completely open the gate with the disabled function,
then activate its closing and see after how many
seconds the photocell operates.
• Set up a slightly lower time into i.ShA menu and a
slightly higher time into F.ShA menu.
• During the time between i.ShA and F.ShA, photocells
(FOTO2) will not be active during the closing phase.
