ENGLISH48OPERATION DEFECTSThis paragraph shows some possible operation defects, alongwith their cause and applicable remedy.MAINS led does not switch onIt means that there is no voltage on CITY1 control unit card.1. Before acting on the control unit, disconnect through thedisconnecting switch on the power line and remove thepower supply terminal.2. Be sure that there is no voltage break upstream the controlunit.3. Check whether the fuse is burnt-out, if so replace it withsame value.OVERLOAD led is onIt means that there is an overload on accessory power supply.1. Remove the extractable part containing terminals 12 to 21.OVERLOAD led will switch off.2. Remove the overload cause.3. Reinsert the terminal board extractable part and check thatthis led is not on again.Error 1The following writing appears on display when you exit fromprogramming:It means that changed data could not be stored.This kind of defect has no remedy and the control unit must besent to V2 for repair.Error 2When a Start command is given and the gate does not open andthe following writing appears on display:It means that triac test failed.Before sending the control unit to V2 for repair, be sure thatmotors have been properly connected.In case motor 2 is not connected, be sure that t.AP2 menu itemis on 0.0”.Error 3When a Start command is given and the gate does not open andthe following writing appears on display:It means that the photocell test failed.1. Be sure that no obstacle interrupted the photocell beamwhen the Start command was given.2. Be sure that photocells, as enabled by their relevant menus,have been installed actually.3. If you have photocells 2, be sure that Fot2 menu item is onCF.CH.4. Be sure that photocells are powered and working; when youinterrupt their beam, you should hear the relay tripping.Error 4After few centimeters during the opening phase the gate stopsand the display shows:It means that the limit switches in closing phase have not beenreleased. Make sure that the limit switches are correctlyconnected and the gate, opening, let the limit switch open.Error 5Once given a start control, the gate does not open and thedisplay shows:It means that the test of the safety edges failed. Make sure thatthe control unit driving the safety edges is correctly connectedand properly working. Make sure that the safety edges enabledby menu are actually installed.Error 7This indicates an error in the encoders' operation.There are three possible causes:1. With the encoders connected, even if they are not enabled,for a few instants after movement of a gate panel. This meansthat the connection to the encoder for that gate panel isreversed. Exchange terminal 12 with 13, or 14 with 152. With the encoders enabled, once a START command isreceived: This means that the encoders have not beeninitialized. For the encoders to operate correctly, theself-learning procedure must be performed.3. With the encoders enabled and initialized, a few seconds aftermovement begins: This means that an encoder is NOTcorrectly operating. Encoder malfunction or broken connection.Error 9When you are trying to change the control unit setups and thefollowing writing appears on display:It means that programming was locked by means of theprogramming lock key (code CL1). In order to enter theconfiguration menu, you will have to insert this key into thespecial OPTIONS connector.Too long pre-blinkingWhen a Start command is given and the blinker switches onimmediately but the gate is late in opening, it means that thesetup cycle count down expired and the control unit shows thatservice is required.
