Operation Defects - V2 CITY2+ Manual Del Usario

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 CITY2+ 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 K1 to K10.
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.
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.
FLAT BATTERY
In absence of line voltage the gate does
not open and on the display flashes the
message:
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 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 S.p.A. for repair.
Error 2
When a Start command is given and the
gate does not open and the display shows:
It means that triac test failed.
Before sending the control unit to V2 S.p.A. for repair, be sure
that motors have been properly connected.
If only one motor is used, connect it to output M1 and
set t.AP2 to 0.
Error 3
When a Start command is given and the
gate does not open and the display shows:
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.
5. Ensure the photocells are connected correctly, as shown in the
dedicated section on page 29
Error 4
When a Start command is given and the
gate does not open (or does a partial
opening) and the display shows:
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.
• If limit switches have not been connected, check that the
FC.En function is set to no.
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.
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
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 K1 with K2, or K3 with K4
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.
PLEASE NOTE: Check the connection is in line with the motor
instructions
Error 8
When executing a self-learning function
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 execute the self-learning
it is necessary that the Start inputs are enabled in standard
mode; to survey the currents of the motor it is also necessary
that the length of the opening and closure are at least of 7,5
second.
Errore 9
When you are trying to change the control
unit setups and the the display shows:
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.
