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 the gate
won't open.
It means that intervention of photocell FOT1
prevents gate movement.
When a start command is given the gate
won't open.
It means that intervention of photocell FOT2
prevents gate movement.
When a start command is given the gate
won't open.
It means that intervention of safety edge
COS1 prevents gate movement.
When a start command is given the gate
won't open.
It means that intervention of safety edge
COS2 prevents gate movement.
When a start command is given the gate
won't open.
It means that STOP input prevents gate
movement.
When a start command is given the gate
won't open.
It means that TRIAC test failed.
When a Start command is given and the
gate does not open (or does a partial
opening).
It means that the limit switche has not been
released or that both limit switches are
active.
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 E1 -
E5 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.
1. Check there are no obstacles between the photocells
and FOT1.
2. Ensure the photocells are powered and working:
interrupt the ray and check that the photocell segment
on the display changes position.
1. Check there are no obstacles between the photocells
and FOT2.
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 COS1 is not pressed or
damaged.
2. Ensure safety edge COS1 is connected correctly:
activate the safety edge and check the safety edge
section on the display changes position.
1. Check the safety edge COS2 is not pressed or
damaged.
2. Ensure safety edge COS2 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.
1. Check the motors are correctly connected.
2. Check the thermal protection on the motor has not
activated.
3. If motor M2 is not connected, ensure the menu item
t.AP2
is set to
4. If no problems are detected on the motors, contact
the V2 technical support service to send the control
unit for repair.
Make sure that the limit switches are correctly connected
and the gate, opening, let the limit switch open.
