13.1 - OPERATION DEFECTS

This paragraph shows some possible operation defects, along
with their cause and applicable remedy.

OVERLOAD led is on

It means that there is an overload on accessory power supply.

Remove the extractable part containing terminals

OVERLOAD led will switch off.

Remove the overload cause.

Reinsert the terminal board extractable part and check that
this led is not on again.

Too long pre-blinking

When a Start command is given and the blinker switches on
immediately but the gate is late in opening, it means that the
setup cycle count down expired and the control unit shows that
service is required.

Error 0

When a start command is given, the gate does not open and the
display shows the message

Err0

This means that the buffer batteries do not have sufficient power
to open the gate. It is necessary to wait for the return of mains
power, or to replace the drained batteries with new ones.

Error 1

The writing

Err1

appears on display when you exit from

programming:

It means that changed data could not be stored.
This kind of defect has no remedy and the control unit must be
sent to V2 S.p.A. for repair.

Error 2

When a Start command is given and the gate does not open and
the display shows

Err2

It means that MOSFET test failed.
Before sending the control unit to V2 S.p.A. for repair, be sure
that motors have been properly connected.

Error 3

When a Start command is given and the gate does not open and
the display shows

Err3

It means that the photocell test failed.

Be sure that no obstacle interrupted the photocell beam
when the Start command was given.

Be sure that photocells, as enabled by their relevant menus,
have been installed actually.

If you have external photocells, be sure that

Foto

menu item

is on

CF.CH

Be sure that photocells are powered and working; when you
interrupt their beam, you should hear the relay tripping.

Ensure the photocells are connected correctly, as shown in the
dedicated section 4.3

Error 4

When a Start command is given and the gate does not open (or
does a partial opening) and the display shows

Err4

It means that the end of stroke is damaged or that the wiring
that connects the sensor to the control unit is broken.
Change the end of stroke sensor or the broken wiring. If the
error persists send the control unit to V2 S.p.A. for repair.

Error 5

Once given a start control, the gate does not open and the
display shows

Err5

It means that the test of the safety edges failed.
Check that the menu of the test of safety edges (

CO.tE

) have

been set correctly.
Check that the safety edges enabled from the menu are
installed.

Error 7

When a Start command is given and the gate does not open (or
does a partial opening) and the display shows

Err7

This indicates an error in the encoders' operation.

There are two possible causes:

Once a START command is received: this means that the

encoders have not been initialized.
For the encoders to operate correctly, the self-learning
procedure must be performed.

A few seconds after movement begins: this means that the
encoder is NOT correctly operating. Encoder malfunction or
broken connection.

Error 8

When executing a self-learning function, one of the following
conditions occurs:

the control is refused and the display shows

Err8

It means that the setting of the control unit is not compatible
with the requested function.
In order to carry out self-learning, the Start inputs must be
enabled in standard mode (

Start

menu set to

StAn

) and the

ADI interface must be disabled (

i.Adi

menu set to

The procedure stops and the displays shows

Err8

It means that a safety device has tripped.

Error 9

When you are trying to change the control unit setups and the
the display shows

Err9

It means that programming was locked by means of the
programming lock key CL1+ (code 161213).
To change the settings it is necessary to insert in the connector
of the ADI interface the same key used to activate the
programming lock, and unlock the device

Error 10

When a start command is given, the gate does not open and the
display shows the message

Er10

This means that the ADI module function test failed.
