    DC bus (generator operation). Acting as interfaces to the IMC15 are a display with a keypad, a CAN bus interface and a digital interface (Dig I/O) that can be configured to meet specific requirements.

  • Page 6: Remarks On Safety

    IMC15 EMARKS ON AFETY During operation, the IMC15 and the electric drive system as a whole may, according to its degree of protection, have moving or rotating parts as well as hot surfaces. Electric drive systems with frequency converters are therefore potentially hazardous.
  • Page 7 2 Remarks on Safety 56.2 Overload, Over-Current, and Over-Speed Protec- tion The motor must have an integral thermal protection PTC according to DIN 44082. The PTC must be connected to the terminal block J2. Max. Motor rating: 29.5Arms AC, 15kW. Le moteur doit avoir une protection intégrée contre surtempé- rature PTC selon DIN 44802.

  • Page 8: Intended Use

    IMC15 NTENDED The IMC15 is intended for use in electrical plants or machines. If used in machines, the commissioning of the IMC15 (start of the intended use) has to be delayed until it has been verified that the machine complies with the regulations of EU directive 98/37/EG (directive for machines).

    5 Operation 5.5 Fault History 5.5.1 Introduction The fault history holds all faults and selfcheck faults that have occurred. It consists of a list of 160 entries that are periodi- cally overwritten (wrap around after 160 faults). It can be accessed sequentially with the last („youngest“) entry being at the top.

  • Page 32: Using The Fault History

    IMC15 5.5.2 Using the Fault History The fault history is accessed through the main menu. In order to view the fault history, the data has to be buffered first (menu page 121). After this, all fault entries can be viewed (menu page 122) and, if more information is required, its cau- ses (details) can be displayed (menu page 123).

  • Page 34: Updating The Firmware

    5.6.1 Introduction In order to prevent a factory recall in case of a firmware update, the IMC15 can be updated using portable flash cards. The firmware consists of three parts. The program code, the parameter files (inifiles) and the display file. As will be descri- bed in the following sections, it is possible to either update the whole firmware or only parts of it.
  • Page 35 After successfully carrying out the update (see following sec- tions) the card has to be removed from the slot and can be used for updating any number of further IMC15 devices. Please keep in mind the following points: • Updates of any kind may only be carried out by qualified personnel using flash cards that have been explicitly made for this application by MECOS AG.

  • Page 36: Complete Update

    If the version number of the program on the IMC15 (Menu page 141 „Version Info“) and on the flash card correspond, no update will be carried out, meaning that neither program nor inifiles nor display files will be updated.
  • Page 37 5 Operation...

  • Page 38: Inifile Update

    Inifiles work with exactly one program version. The IMC15 will not carry out an inifile update if it is not intended to be used with the program version on the device to be updated. Since...

  • Page 40: Display Update

    IMC15 5.6.5 Display Update If the display‘s contents are to be modified, a display update has to be carried out. The proceeding of the display update is identical to the the ini- file update. Should there be necessity to update both inifile and display file, it can be done simultaneously provided both updates are stored on the same flash card.

  • Page 42: Troubleshooting

    In order to facilitate diagnosis, all warning and fault messages of the device supervision are assigned to one of the following 9 categories. Fault category Description IMC15 is defective Replace IMC15 Sensor fault Defective sensor cabling possible. Check sensor cabling and installation first.
