    The devices are supplied with a generic “default” configuration; it is at the installer’s care to adjust the operating parameters to the specific application. SICES srl carries out a great effort to improve and update its products; therefore, they are subject to both hardware and software modifications without notice. Some of the features described in this manual may therefore differ from those present in your device.

  • Page 14: Conventions

    Several parts of this manual refer to the controller's software revisions. These revisions are marked with the assigned SICES code (shown on the rear panel of the controller). The format of the code is: EB0250256XXYY, where “XX” is the main version and “YY” is the minor version.
