14 - OPERATION DEFECTS
This paragraph shows some possible operation defects, along
with their cause and applicable remedy.
Some anomalies are signalled using a message on the display,
others with flashing signs or the leds assembled on the control
unit.

DESCRIPTION
It means that there is no voltage on control
unit card.
It means that there is an overload on
accessory power supply.
When a Start command is given and the
blinker switches on immediately but the
gate is late in opening
When a Start command is given the gate
will be closed at slow speed until the closed
range limit and after resumes normal
operation
When a start command is given the gate
won't open.
It means that TRIAC test failed.
When a start command is given the gate
won't open.
It means that the photocell test failed.
When a Start command is given and the
gate does not open
SOLUTION
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.
1. Remove the extractable part containing terminals M1 -
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.
It means that the setup cycle count down expired and the
control unit shows that service is required
This condition can occur when the motor encoder must
be realigned.
This anomaly can occur due to power failure with
the gate open or due to other factors related to the
malfunctioning of the gate.
Before sending the control unit to V2 S.p.A. for repair, be
sure that motors have been properly connected.
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
CF.Ch
item is on
4. Be sure that photocells are powered and working:
interrupt the ray and check that the photocell segment
on the display changes position.
This anomaly can occur when in one of the following
conditions:
1. If a START command is sent with the motor released.
2. During the self-learning cycle if there are any problems
with the range limits.
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.
3. During normal operation. If the error persists send the
control unit to V2 S.p.A. for repair.
