Method of maintenance of an electromechanical device

A method of maintenance of an electromechanical device, wherein said electromechanical device is controlled by an electronic control unit suitable to monitor a status of operating parameters of the electromechanical device and to carry to a data output port of said electronic control unit, status signals indicative of the state of said operating parameters and/or alarm signals if the state of said parameters is not within a predetermined range, wherein the electronic control unit comprises a control unit data communication means in communication with the output port, the method comprising the steps of:

• making available to the control unit data communication means based on a wireless communications protocol, to enable transmission to a portable electronic device external to the electromechanical device, said status signals and/or alarm signals;
• wherein the portable device comprises a processing unit provided with means for receiving data;
• providing an operator with the portable electronic device, said processing unit being operatively connected to a database in which a list of maintenance operations executable on the electromechanical device is stored, said processing unit being further programmed to interpret any alarm signal received from the electronic control unit or to generate alarm signals on the basis of output signals status corresponding to the received data, and to correlate each alarm signal received or generated with at least one of said maintenance operations, the portable electronic device further comprising an operator interface operatively connected to the processing unit;
• activating data communication between the electronic control unit and the processing unit and transferring from the electronic control unit to the processing unit the status signals and/or possible alarm signals;
• if at least one alarm signal is present correlating, by means of the processing unit, said the at least one alarm signal with at least one maintenance operation and communicating to the operator, through the operator interface, said the at least one alarm signal and the at least one maintenance operation related to said alarm signal,
• wherein if one of said at least one maintenance operation is a reboot of the electronic control unit, asking the operator, by the processing unit if the processing unit should proceed with a reboot operation, and, in response to getting an affirmative response from the operator, rebooting, by the processing unit, the control unit and asking the operator to wait for restoration of communication between the processing unit and the control unit.
