V2 SPA CITY4 Mode D'emploi page 38

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.
• 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 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 input
This menu allows enabling the input for photocells (see paragraph
"Installation").
no input disabled (ignored by the control unit).
No jumper with the common is required.
CF.CH input enabled even at standstill gate too: the opening
movement does not start if photocell is interrupted.
CH input enabled for the closing phase only
Warning: if you select this option, you must disable photocell
test.
Test of safety devices
In order to achieve a safer operation for the user, the unit performs a
safety devices operational test, before a normal working cycle.
If no operational faults are found, the gate starts moving. Otherwise, it
will stand still and the flashing light will stay onfor 5 sec. The whole test
cycle lasts less than one second.
no function not active
Foto test enabled only for photocells
CoSt test only enabled for the safety edges
(or for the additional photocells)
Ft.Co test enabled either for photocells or for safety edges
WARNING: The PHOTOCELL OPERATIONAL TEST should be working
in order to grant more safety during installation and programming.
WARNING: it is possible to test safety edges only if a control unit
specially provided for this function has been installed.
If using conductive rubbers do not activate the test, as the control unit
continuously check their functionality.
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 29), provided
that this function has been enabled in advance by setting
any time in the menus i.ShA and F.ShA (also 0.0").
