13.1 - OPERATION DEFECTS
This paragraph shows some possible operation defects, along
with their cause and applicable remedy.
MAINS led does not switch on
It means that there is no voltage on PD20 control unit card.
1. Before acting on the control unit, disconnect through the
disconnecting switch on the power line and remove the
power supply terminal.
2. Be sure that there is no voltage break upstream the control
unit.
3. Check whether the fuse is burnt-out, if so replace it with
same value.
OVERLOAD led is on
It means that there is an overload on accessory power supply.
1. Remove the extractable part containing terminals M1 to M12.
OVERLOAD led will switch off.
2. Remove the overload cause.
3. Reinsert the terminal board extractable part and check that
this led is not on again.
Error 1
The following writing appears on display when you exit from
Err1
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 following writing appears on display
This indicates an error in the inverter board operation.
NOTE: If the motor has been heavily used, the motor driver may
have overheated. Let it cool and try again.
Error 3
When a Start command is given and the gate does not open and
the following writing appears on display
It means that the photocell test failed.
1. Be sure that no obstacle interrupted the photocell beam
when the Start command was given.
2. Be sure that photocells, as enabled by their relevant menus,
have been installed actually.
3. If you have photocells 2, be sure that Fot2 menu item is on
CF.CH.
4. Be sure that photocells are powered and working; when you
interrupt their beam, you should hear the relay tripping.
Error 4
When a Start command is given and the gate does not open (or
does a partial opening) and the following writing appears on
Err4
display
This means there is a problem with the limit switch.
Check the direction of the magnets, if they are backwards, they
should be removed and inverted.
If the magnets are installed correctly, it means that the limit
switch sensor is damaged or the cabling connecting the sensor
to the central control unit is broken/damaged.
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.
Err2
Err3
67
Error 5
Once given a start control, the gate does not open and the
Err5
display shows
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 6
During the manoeuvre the motor stops and the display shows
Err6
It means that there are communication problems with the
inverter board. If the problem persists, the control unit must be
sent to V2 SpA for repair.
Error 7
When given a start control the gate does not open and the
Err7
display shows
This indicates an error in the encoders' operation.
Encoder malfunction or broken connection.
Error 8
When executing a self-learning function, one of the following
conditions occurs:
1. the control is refused and the display shows
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 no).
2. The procedure stops and the displays shows
It means that a safety device has tripped.
Error 9
When you are trying to change the control unit setups and the
following writing appears on display
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 12
When a Start command is given and the gate does not open (or
does a partial opening) and the following writing appears on
Er I2
display
This means the motor overheating protection has tripped.
The system will start working again as soon as the motor has
cooled.
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.
