Another command is already present. Remove the command present to be able to
send other commands.
The time-out denotes that the manoeuvre is too long. Shorten the manoeuvre time by
increasing the speed or balancing the gate to reduce the motor's effort. If the motor
lacks power check whether the board is properly inserted in its housing

During normal operation it indicates fast "Motor speed"
- Function programming in progress
- If it flashes together with LEDs L1 and L3, the user must run the recognition phase of the gate opening
and closing positions (Paragraph 7.3).
Description
During normal operation the device indicates "Automatic Closing" is inactive.
During normal operation the device indicates "Automatic Closing" is active.
- Function programming in progress

Description
During normal operation it indicates that a radio code not present in the memory has been received.
Transmitter programming or deletion under way
Solution
Make sure there is power supply; check to see whether the fuses are blown;
if necessary, identify the reason for the failure then replace them with others
of the same type.
Try switching off the control unit for a few seconds; if the condition persists,
it means that there is a malfunction and the electronic circuit board has to
be replaced.
Normal control unit operation.
This is normal when there is a change in one of the inputs: SbS, STOP, inter-
vention of photocells or the radio transmitter is used.
Same signal on the warning light or courtesy light: see Table 20
Solution
Check the devices connected to the STOP input
