18 - 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.

of the rear of the container

DESCRIPTION
It means that there is no voltage on control
unit card.
NOTE: the led is never switched on if
the motor is battery operated
It means that there is an overload on
accessory power supply.
It means there is no power available for the
motor and accessories
When a Start command is given and the
blinker switches on immediately but the
gate is late in opening
When a command is given to start, the
boom does not lift (or does not close again).
It means the intervention of the photocell
prevents barrier manoeuvre.
When a command is given to start, the
boom does not lift (or does not close again).
It means the intervention of the rib prevents
barrier manoeuvre.
When a start command is given, the barrier
does not open.
It means that STOP input prevents gate
movement.
The barrier is raised without receiving any
control and cannot close again. It means
the fire alarm is on.
The barrier has raised and the control unit
refuses the closure commands. It means
the presence sensor is enabled.
It means that MOSFET test failed
When a start command is given, the barrier
does not open.
It means that the photocell test failed.
NOTE: following an anomaly, the error message displayed
on the display stays active until the control unit receives a
START command or the MENU key is pressed.
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 J1 -
J9 and Z1 - Z6 . 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
Check the transformer connections. If the transformer is
connected correctly, send the control panel and transformer
for repair.
It means that the setup cycle count down expired and the
control unit shows that service is required (chapter 12)
1. Check there are no obstacles between the photocells.
2. Ensure the photocells are powered and working:
interrupt the ray and check that the photocell segment
on the display changes position
1. Check the safety edge is not pressed or damaged.
2. Ensure safety edge is connected correctly: activate the
safety edge and check the safety edge section on the
display changes position.
1. Check the STOP button is not pressed.
2. Ensure the button is working correctly
Check the signalling causes and, if necessary, reset
operation.
Remove the cause of sensor enabling. If no object or
person engages the presence sensor, it means the sensor is
faulty or not aligned.
Contact the V2 technical assistance service to send the
control unit for repair
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. Be sure that photocells are powered and working:
interrupt the ray and check that the photocell segment
on the display changes position.
4. Ensure the photocells are connected correctly, as shown
in the chapter 5.5
