WHATTODOIF…(Troubleshootingguide)

9.1 - DIAGNOSTICS

Some devices are display messages to identify their status and faults.

The following paragraphs describe the messages available with the different types of device.

9.2 - Troubleshooting

Table 17 gives some troubleshooting procedures, for use during installation and in case of malfunctions.

TABLE 17

Troubleshooting

01. The radio transmitter does not control the gate and the

led on the transmitter does not light up

Check to see if the transmitter batteries are exhausted, if necessary replace them

02. The radio transmitter does not control the gate but the

led on the transmitter lights up

Check to see if the transmitter has been memorised correctly in the radio receiver

03. No manoeuvre starts and the “BlueBus” led does not

ash

Check that RUN is powered off the mains.

Check to see if fuses F1, F2 or F3 are blown; if necessary, identify the reason for the failure

and then replace the fuses with others having the same current rating and characteristics

04. Nomanoeuvrestartsandtheasherisoff Make sure that the command is actually received. If the command reaches the STEP-BY-

STEP input, the corresponding “STEP-BY-STEP” led must light up; if you are using the radio

transmitter,the“BlueBus”ledmustmaketwoquickashes.

05. No manoeuvre starts and the flasher flashes a few

times

Counttheashesandcheckthecorrespondingvalueintable19

06. The manoeuvre starts but it is immediately followed by

a reverse run

The selected force could be too low for this type of gate. Check to see whether there are any

obstacles; if necessary increase the force

07. Themanoeuvreiscarriedoutbuttheasherdoesnot

work

Makesurethatthereisvoltageontheasher’sFLASHterminalduringthemanoeuvre(being

intermittent, the voltage value is not important: approximately 10-30Vdc); if there is voltage,

the problem is due to the lamp; in this case replace the lamp with one having the same

characteristics;ifthereisnovoltage,theremayhavebeenanoverloadontheFLASHoutput.

Check that the cable has not short-circuited.

08. The manoeuvre is carried out but the Open Gate Indi-

cator does not work

Check the type of function programmed for the S.C.A. output (Table 8)

When the light should be on, check there is voltage on the S.C.A. terminal (approximately

24Vdc). If there is voltage, then the problem will have been caused by the light, which will

have to be replaced with one with the same characteristics. If there is no voltage, there may

have been an overload on the S.C.A. output. Check that the cable has not short-circuited.

9.3 - Malfunctions archive

RUN can display any faults that have occurred in the last 8 manoeuvres, for example interruption of a manoeuvre due to activation of a photocell or sensitive edge.

To check the list of faults, proceed as for Table 18:

TABLE 18

Malfunctions log

01. Press and hold the “Set” key for about 3 seconds;

02. Release “Set” when led L1startsashing;

03.

Press key “s” or “t”tomovetheashingledontoL8,i.e.the“inputled”fortheMalfunctionsLogparameter;

04. Press and hold down “Set” throughout steps 5 and 6;

05. Wait approx. 3s after which the leds corresponding to the manoeuvres subject to faults will light up. Led L1 indicates the result of the last manoeuvre

and L8 indicates the result of the 8th manoeuvre. If the led is on, this means that a defect occurred during that manoeuvre; if the led is off, this means

that no defect occurred during that manoeuvre;

06.

Press keys “s” and “t”toselecttherequiredmanoeuvre:thecorrespondingledashesthesamenumberoftimesasthosemadebytheasherafter

a defect (see table 19);

07. Release the “Set” key.

9.4 - Flasher signals

Ifyouconnectaashertothecontrolunit'sFLASHoutput(oraledasherprogrammedtoactasaasher),itwillashonceasecondduringmanoeuvres.Ifany

faultsarise,theasherwilldisplaywarningsignalswhichrepeattwicewitha1secondpausebetweenthem.ThesamesignalsaredisplayedbytheBlueBusled

andtheledasher.Table19describesthecausesandsolutionsforeachsignal.

BlueBus error The BlueBus connected device check, run at the start of the manoeuvre,

does not match the devices memorised during device recognition. Some

faulty devices may be present; check and replace them as necessary.
