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 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 12 to 21.
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
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 for repair.
Error 2
When a Start command is given and the gate does not open and
the following writing appears on display:
It means that triac test failed.
Before sending the control unit to V2 for repair, be sure that
motors have been properly connected.
In case motor 2 is not connected, be sure that t.AP2 menu item
is on 0.0".
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
After few centimeters during the opening phase the gate stops
and the display shows:
It means that the limit switches in closing phase have not been
released. Make sure that the limit switches are correctly
connected and the gate, opening, let the limit switch open.
Error 5
Once given a start control, the gate does not open and the
display shows:
It means that the test of the safety edges failed. Make sure that
the control unit driving the safety edges is correctly connected
and properly working. Make sure that the safety edges enabled
by menu are actually installed.
Error 7
This indicates an error in the encoders' operation.
There are three possible causes:
1. With the encoders connected, even if they are not enabled,
for a few instants after movement of a gate panel. This means
that the connection to the encoder for that gate panel is
reversed. Exchange terminal 12 with 13, or 14 with 15
2. With the encoders enabled, 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.
3. With the encoders enabled and initialized, a few seconds after
movement begins: This means that an encoder is NOT
correctly operating. Encoder malfunction or broken connection.
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 (code CL1).
It is essential to insert the key into the specific OPTIONS
connector and unlock the control unit prior to altering the
settings.
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.
