The manoeuvre starts but it is immediately fol-
lowed by a reverse run
Check to see if the transmitter batteries are exhausted, if necessary replace them
Check the transmitter has been memorised correctly in the radio receiver
Check the correct emission of the transmitter radio signals with the following empirical test: push the
buttonandresttheLEDagainsttheaerialofanormalhouseholdradio(ideallyinexpensive)thatis
switched on and tuned in at 108.5 Mhz FM or as close as possible; a low sound should be heard with
crackling pulses

blown (g. 26); if necessary, identify the reason for the failure and then replace the fuses with others
having the same current rating and characteristics
Make sure that the command is actually received. If the command reaches the “Step-by-Step” input the

The selected force could be too low for this type of door. Check to see whether there are any obsta-
cles; if necessary increase the force
Quick ashes Cause ACTION

At the starting of the manoeuvre, one or more photocells do not enable it; check to see if
there are any obstacles
This is normal when there is an obstacle impeding the movement
During the movement, the door experienced excessive friction; identify the cause
At the starting of the manoeuvre or during the movement ,the STOP input was activated;
identify the cause
Waitatleast30seconds,thentrygivingacommand.Ifnothinghappenstheremaybea
serious fault and the electronic card will have to be replaced
Waitforafewminutesuntilthemanoeuvrelimitingdevicedropstounderthemaximumlimit
Disconnect all the power circuits for a few seconds and then try to give the command
again. If nothing happens there may be a serious electronic card or motor cabling fault.
Carry out a control and possible replacement

7.7.2 - Signals on the control unit
On the Road400 control unit there is a set of LED each of which can give special indications both during normal operation and in case of malfunctions.
TABLE 21 - Led’s on the control unit’s terminals (g. 27)
Led OK Cause Action
Led STOP Cause Action
Make sure there is power supply; check to see if the fuses are blown; if necessary, identify the
reason for the failure and then replace the fuses with others having the same characteristics
There is a serious malfunction; try switching off the control unit for a few seconds; if the con-
dition continues it means there is a malfunction and the electronic board has to be replaced

7.7 - Diagnostics and signals
A few devices issue special signals that allow you to recognize the operating
status or possible malfunctions.
