See here the solutions to a variety of different faults that can occur for the Digivoice digital panels 1038/10/12/16.
Fault:
The call module (panel) 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 (panel) 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 (panel) 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.
Fault:
The call module shows “FLASH ERROR”. - 1038/12 and 1038/16 only
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.
