V2 City4 Manual De Instrucciones página 36

• During the time between i.ShA and F.ShA, photocells will not be active during the closing phase.
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 ELETTRONICA 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 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.
The door travel, during which photocells are not active,
is measured in seconds from the beginning of the door
closing and starting from the max. opening position.
The shadow zone limits are automatically set during the
self-learning phase (see paragraph page 27), provided
that this function has been enabled in advance by
setting any time in the menus i.ShA and F.ShA (also
0.0"). If it is necessary to set the limits manually,
follow these instructions:
• 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.
Safety ribbon input
This menu allows the enabling of the safety ribbons and the setting of
their operation logic (see paragraph "Installation").
no Input disabled (ignored by the control unit).
No jumper with the common is required.
StAn input enabled for standard safety ribbons with n.c. contact
rESi input enabled for conductive rubber safety ribbons with
nominal resistance 8,2 kohm.
End of Stroke Inputs
City4 control unit allows connecting 2 mechanical ends of stroke
(normally closed contacts) which are activated by the door motion and
showing to the control unit that each door reached its position of
complete opening or closing.
no end of stroke inputs are disabled
StoP inputs enabled: the gate stops near the limit switches
rALL inputs enabled: the gate starts the slowdown phase (menu
t.rAL) near the limit switches.
