Digivoice

System power supply Ref.1038/20

Fault: The led "ON" of power supply unit is off.

Solution: Check the mains, if it is ok then disconnect the terminal "+V" and measure the voltage between terminals "+V" and "0V".If the reading is between +21Vdc and +24Vdc, section the system in order to find the short-circuit on the powering line (+V; 0V); while if the reading is lower than +21Vdc, replace the power supply unit.

------------------------------------------------------------------------

Fault: The "ON" led of the power supply is red on.

Solution: Check the connections of the powering line (+V; 0V), as the led "ON" red shows that terminals "+V" of two or more power supplies are connected together.

------------------------------------------------------------------------

Fault: The "ON" led of the power supply is red flashing.

Solution: Check all power supply units in the system, only one must be set as "MASTER" (jumper M1-M2). Check the terminal "DE" of "MASTER" power supply, as this terminal must not be used in this power supply unit.

------------------------------------------------------------------------

Fault: The "DE" led of the power supply is on.

Solution: Measure the voltage between terminals "DE" and "0D", if the voltage is lower than +13,5Vdc, find the reason of voltage drop or short-circuit.If the "DE" led is on in the "MASTER" power supply, check the terminal "DE" It must not be used.

------------------------------------------------------------------------

Fault: The "DU" led of the power supply is on.

Solution: Measure the voltage between terminals "DU" and "0D", if the voltage is lower than +13,5Vdc, find the reason of voltage drop or short-circuit.

------------------------------------------------------------------------

Call modules Ref.1038/10 -/12 -/16

Fault: The call module does not start up.

Solution: Measure the voltage between terminals "+V" and "0V", if the voltage is lower than +16Vdc, find the reason of voltage drop or short-circuit.

------------------------------------------------------------------------

Fault: The call module shows "ERROR DATA LINE" or "Err3".

Solution: Measure the voltage between terminals "D" and "0V", if the voltage is lower than +13,5Vdc, find the reason of voltage drop or short-circuit.

------------------------------------------------------------------------------------------------------------------------

Fault: The call module shows "EEPROM ERROR" or "ErCE".

Solution: Enter the programming mode of the call module directly by its keyboard and then scroll through all programming steps until you exit the programming mode.

------------------------------------------------------------------------

Call modules Ref.1038/12 -/16 only

Fault: The call module shows "FLASH ERROR".

Solution: Enter the names and door opener codes programming of the call module directly by its keyboard, when the call module shows the first programming window then exit the programming mode.

<Names>
<Lock rel. codes><Esc> 1st program window

------------------------------------------------------------------------

Digitizers Ref.1038/5 -/62

Fault: The digitizer does not give out any confirm tone when making a call.

Solution: Measure the voltage between terminals "+V" and "0V", if the voltage is lower than +16Vdc, find the reason of voltage drop or short-circuit.

------------------------------------------------------------------------

Fault: The digitizer gives out a stream of 6 beeps every 3 seconds.

Solution: Measure the voltage between terminals "D" and "0V", if the voltage is lower than +13,5Vdc, find the reason of voltage drop or short-circuit.

------------------------------------------------------------------------

Fault: The digitizer gives out a stream of beeps every 5 seconds.

Solution: Enter the programming mode of the digitizer by programming terminal Ref.1038/55 v.2.00 or Ref.1038/56 and then scroll all programming steps until you exit the programming mode.

-------------------------------------------------------------------------

Fault: Only the first eight keys of digitizer work properly.

Solution: Check the connection between the digitizer and the expander modules.

------------------------------------------------------------------------

4 User decoders Ref.1038/34 -/35 and door phone with single decoder Ref.1138/31

Fault: When pressing the programming key the led does not light up.

Solution: Measure the voltage between terminals "+V" and "0V" of decoder box, if the voltage is lower than +16Vdc, then find the reason of voltage drop or short-circuit.

------------------------------------------------------------------------

Fault: The programming led flashes continuously.

Solution: Measure the voltage between terminals "D" and "0V", if the voltage is lower than +13,5Vdc, find the reason of voltage drop or short-circuit.

------------------------------------------------------------------------

Switchboard Ref.1038/40

Fault: The switchboard does not start up.

Solution: Measure the voltage between terminals "+V" and "0V" of switchboard, if the voltage is lower than +16Vdc, find the reason of voltage drop or short-circuit.

-------------------------------------------------------------------------

Fault: The display shows "ERROR DATA LINE".

Solution: Measure the voltage between terminals "D" and "0V", if the voltage is lower than +13,5Vdc, find the reason of voltage drop or short-circuit.
