Diagnostics And Signals - Nice Road400 Instructions Et Avertissements Pour L'installation Et L'utilisation

7.6 - Troubleshooting
The table 19 contains instructions to help you solve malfunctions or errors that may occur during the installation stage or in case of failure.
Symptoms
The radio transmitter does not control the gate
and the LED on the transmitter does not light up
The radio transmitter does not control the gate
and the LED on the transmitter lights up
No manoeuvre starts and the OK LED does not
flash
No manoeuvre starts and the flashing light is off
No manoeuvre starts and the flashing light
flashes a few times
The manoeuvre starts but it is immediately fol-
lowed by a reverse run

7.7 - Diagnostics and signals

A few devices issue special signals that allow you to recognize the operating
status or possible malfunctions.
Quick flashes Cause
2 flashes Triggering of a photocell
1 second's pause
2 flashes
3 flashes Activation of the "motor force"
1 second's pause limiting device
3 flashes
4 flashes Activation of the STOP input
1 second's pause
4 flashes
5 flashes Error in the internal parameters
1 second's pause of the electronic control unit
5 flashes
6 flashes The maximum manoeuvre
1 second's pause limit/hour has been exceeded
6 flashes
7 flashes There is an error in the internal
1 second's pause electric circuits
7 flashes
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.
Led OK Cause
Off Malfunction
On Serious malfunction
One flash every second Everything OK
2 quick flashes The status of the inputs has
changed
Series of flashes separa- Miscellaneous
ted by a second's pause
Led STOP Cause
Off Activation of the STOP
input
On Everything OK

TABLE 19 - Troubleshooting
Probable cause and possible solution
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
Check that Road400 is powered by a 230V mains supply. Check to see if the fuses F1 and F2 are
blown (fig. 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
OK LED flashes twice indicating that the command has been received
Count the flashes and check the corresponding value in table 20
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
TABLE 20 - FLASH flashing light signalling
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
TABLE 21 - Led's on the control unit's terminals (fig. 27)
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
Normal operation of control unit
This is normal when there is a change in one of the inputs: SEP-BY-STOP, STOP, triggering
of photocells or the radio transmitter is used
It corresponds to the flashing light's signal. See Table 20
Action
Check the devices connected to the STOP input
STOP Input active
7.7.1 - Flashing light signalling
During the manoeuvre the flashing light flashes once every second. When some-
thing is wrong the flashes are more frequent; the light flashes twice with a 1
second pause between flashes.
