WARNING! All work related to the EXCOUNT-II´s sensors and the surge arresters shall be made with disconnected and earthed conductors. Follow all regulations and rules stated by international or national safety regula- tions.
EXCOUNT-II incorporates a sensor, which is mounted on the surge arrester, a transceiver, for remote reading and a PC-program (Windows 95/98/2000/ME and NT). This users manual desribes the functions of EXCOUNT-II to give you total control over surge monitoring. Table of contents 1.
To turn off the transceiver press Normal maintenance To achieve the best possible lifetime out of your EXCOUNT-II Transceiver, avoid exposure to strong sunlight for extended periods, hot temperatures (over +50 º C), cold temperatures (under -10 º C ) and water (the design is showerproof but not watertight).
Particulary ensure that the date and clock on the Transceiver are set correctly. Load the EXCOUNT-II software onto your PC and famliarize yourself with its use by reading the individual HELP files within each respective section. Installation/unistallation of software Installation of software Insert the CD into your computer.
