This is normal when there is an obstacle impeding the movement.

3 flashes

1 second’s pause

3 flashes

Activation of the “motor force” limiting device 

During the movement, the gate experienced excessive friction; 

identify the cause.

6 flashes

1 second’s pause

6 flashes

The maximum manoeuvre limit/hour has been exce-

eded

Wait for a few minutes until the manoeuvre limiting device drops to 

under the maximum limit

7 flashes

1 second’s pause

7 flashes

Here is an error in the internal electric circuits 

Disconnect all the power circuits for a few seconds and then try 

to give the command again. if the condition persists it means 

there is a serious malfunction and the electronic board has to be 

replaced

8 flashes

1 second’s pause

8 flashes

A command that does not permit other commands 

to be performed is already present

Check the type of command that is always present; for example, 

it could be a command from a timer on the “open” input
