Safety instructions Do not connect the Transceiver to other voltage sources than a standard 9 volt battery type 6LR61/PP3 Ensure that the battery is connected correctly. The Transceiver contains a radio transmitter and receiver which must not be used where the use of radio transmitters or other electronic devices is prohibited. 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. Normally, the EXCOUNT-II´s sensors and the surge arresters operate at a high voltage. Therefore they must be installed in such a way that only qualified personnel has access to them.

EXCOUNT-II is an advanced surge arrester monitor for effectively, reliably and safety monitoring and recording surges on high voltage electrical networks. 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. Using the transceiver Description of the buttons 4 Normal maintenance 4 2.

To turn on the transceiver press 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). To clean the transceiver use only a damp soft cloth with a mild detergent. Using the transceiver

Getting started First time usage Open the package and verify that the following items are present together with this manual: Transceiver Data cable (RS232) CD with software Familiarize yourself with the above safety instructions. Fit a new 9 volt battery type 6LR61/PP3. Press the button on the front panel and verify that the transceiver powers up and that the stand-by menu appears. Press the button and verify that the transceiver powers down. Using this manual together with the transceiver and familiarize yourself with the different menus and how they are used. 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. Press the START button in lower left corner Select SETTINGS then CONTROL PANEL Double-click on the icon ADD/REMOVE PROGRAMS Select ADD NEW PROGRAMS Follow the instructions on the screen Uninstalling of software Press the START button in lower left corner Select SETTINGS then CONTROL PANEL Double-click on the icon ADD/REMOVE PROGRAMS Browse to the EXCOUNT-II software and click REMOVE

Administration of Sensors Fit the sensor to the arrester as described in the installation instructions supplied with it. Record the following details as specified in the EXCOUNT-II HELP system for administration: station data arrester data EXCOUNT-II data Input this data into the software as described in the HELP system. IMPORTANT! After installation of a new sensor and input of the adminis- tration details, an initial reading must always be made to establish a link between the administration details in the PC software and the sensor on site. Connect the transceiver to the PC via the data cable Download the sensor’s ID from the EXCOUNT-II software into the Transcei- ver. IMPORTANT! Check that the date and time on the Transceiver are correct, otherwise set them as described in this manual. Note! If this is not done the date stamp from the sensor will be incorrect. Before going to site, check the Transceiver’s battery status. If necessary, install a new battery. Once at site, individually check that it is possible to make contact with each sensor. This is most easily done by taking a leakage current mea- surement as described in this manual. If the sensor is not connected properly, an error code will be displayed on the Transceiver. If desired, a full set of measurements can be made for reference and then transferred to the PC software as described in the HELP system for Transfer data. Getting started

Transceiver error codes Error code 01 11 21 31 32 41 42 51 52 Description System error Prohibited action Checksum error EEPROM data read error EEPROM data write error Low temperature High temperature Too low field probe current Too high field probe current Suggested cause and action Turn off the transceiver and re-start. If the error persists, a serious internal fault has occurred with the Transceiver. Contact your EXCOUNT-II service representative. The user has attempted to do something which is prohibited. An error occurred in the data transmission and the data has been lost or corrupted. Interference from a nearby cellular/mobile phone can be a likely cause. Try to re-transmit the data. The transceiver could not read from the internal EEPROM memory. Turn off the transceiver and re-start. If the error persists, contact your EXCOUNT-II service representative. The transceiver could not write to the internal EEPROM memory. Turn off the transceiver and re-start. If the error persists, contact your EXCOUNT-II service representative. The ambient temperature is lower than defined in the data- base for resistive current measurements. (Lowest defined temperature is -10 º C). Take new measurements at another time. The ambient temperature is higher than defined in the data- base for resistive current measurements. (Highest defined temperature is +60 º C). Take new measurements at another time. The system voltage is too low to generate sufficient current in the field probe in the sensor. Check that the line is correctly energised. The system voltage is too high. Check that the line is cor- rectly energised.

Transceiver error codes Suggested cause and action The measured leakage current is too low. Check that the line is correctly energised. The measured leakage current is too high. Check that the line is correctly energised. If so, try taking another measurement. If the error persits, the arrester may be suspect. A stable value for the leakage current cannot be measured. A likley cause may be an unstable line voltage. Take new measurements at another time. The sensor ID was not recognised by any locally present sensor. Try retransmitting again. If contact still cannot be established, check: a) the chosen sensor ID is present at this station b) the distance to the sensor is not too far (max 60 m, but can depend on interference from buildings and structures) c) interference from a cellular/mobile phone d) battery status to ensure the voltage in the transceiver battery is not too low Turn off the transceiver and re-start. If the error persists, a serious internal fault has occurred with the Transceiver. Contact your EXCOUNT-II service representative. The sensor recognised it’s ID but the connection was lost during the transmission. Try re-transmiting again. If the error persists, check: a) the distance to the sensor is not too far (max 60m, but can depend on interference from buildings and structures). b) interference from a cellular/mobile phone. c) battery status to ensure the voltage in the transceiver battery is not too low.
