10. Transceiver error codes
Error code
Description Suggested cause and action 01 System error The transceiver could not perform the
requested task. Turn off the transceiver and restart. Attempt with individual readings rather than total reading (if this was the case). If the error persists, a serious inter- nal fault may have occured. Contact your EXCOUNT-II service representative.
11 Prohibited action The user has attempted to do something which is prohibited. For example, it is not permitted to re-transmit an already successful transmission.
Turn off the transceiver and restart.
21 Checksum error An error occurred in the data transmission and the data has been lost or corrupted.
Interference from a nearby high-frequency source can be a likely cause. Wait 30 seconds before attempting to retransmit the data. Attempt with individual readings rather than total reading (if this was the case).
31 EEPROM data read error The transceiver could not read from the inter- nal EEPROM memory. Turn off the transceiver and restart. If the error persists a serious internal fault may have occured. Contact your EXCOUNT-II service representative.
32 EEPROM data write
error The transceiver could not write to the inter- nal EEPROM memory. Turn off the transcei- ver and restart. If the error persists, contact your EXCOUNT-II service representative.
41 Low temperature The ambient temperature is lower than defi- ned in the database for resistive current mea- surements, (lowest defined temperature is -10 º C). Take measurements at another time.
42 High temperature The ambient temperature is higher than defined in the database for resistive current measurements, (highest defined temperature is +60 º C). Take measurements at another time.
10. Transceiver error codes
Error code
Description Suggested cause and action 51 Too low field probe
current The system voltage is too low to generate suf- ficient current in the field probe in the sensor.
Check that:
a) the line is correctly energized.
b) the sensor is correctly mounted.
If none of the above are found to be the cause, take measurements at another time.
52 Too high field probe
current The system voltage is too high and generating excessive current in the field probe in the sensor.
Check that:
a) the line is correctly energized.
b) the sensor is correctly mounted.
If none of the above are found to be the cause, take measurements at another time.
61 Low leakage current The measured leakage current is too low (< 0.2 mApeak).
Check that:
a) the line is correctly energized.
b) the sensor is correctly mounted.
If none of the above are found to be the cause take measurements at another time.
62 High leakage current The measured leakage current is too high (> 12 mApeak).
Check that:
a) the line is correctly energized.
b) the sensor is correctly mounted.
If none of the above are found to be the cause take measurements at another time.
If the error persists the surge arrester may be suspect.

Error code
Description Suggested cause and action 70 Unstable leakage
current
A stable value for the leakage current cannot be measured. A likely cause may be an unsta- ble line voltage. Take measurements at another time.
71 Operating voltage out of range
The operating voltage for compensation of resistive leakage current measurement is out of range (0.4 to 0.9 p.u. of arrester Ur). Verify the value given as described in section 5.3.3.1.
80 Sensor not found
Read the safety informa- tion in section 3 carefully before working with the sensor.
The sensor ID was not recognised by any locally present sensor. Wait 30 seconds before retransmitting again. If contact still cannot be established, check:
a) the chosen sensor ID is present at this station b) the distance and orientation to the sensor is
as described in section 4.
c) interference from a high frequency source d) battery status to ensure the transceiver
battery voltage is sufficient.
e) antenna status to ensure it is correctly enabled.
Note! If none of the above are found to be the cause, then consider the following:
When the energy in the sensor falls below a certain level, the sensor switches off the listening function (to conserve energy for recording) until such time that the energy level is sufficient again for com- munication. This may occur if many attempts to communicate have been made in a row or because there is insufficient sunlight and/or electrical field.
Should unexplained difficulties occur during com- munication, it is suggested to wait until another time to make measurements or else install a 9V battery in the sensor.
Error code
Description Suggested cause and action 81 Transmission buffer
error
The transceiver registred a buffer error. Turn off the transceiver and restart. Attempt with individual readings rather than total reading (if this was the case). If the error persists, a serious internal fault may have occured.
Contact your EXCOUNT-II service represen- tative.
82 Connection lost
Read the safety information in section 3 carefully before working with the sensor.
The sensor recognised its ID but the con- nection was lost during the transmission.
Wait 30 seconds before re-transmiting again.
If the error persists, check:
a) the distance and orientation to the sensor is as described in section 4.
b) interference from a high frequency source c) battery status to ensure the transceiver-
battery voltage is sufficient.
d) antenna status to ensure it is correctly enabled.
Note! If none of the above are found to be the cause, then consider the following:
When the energy in the sensor falls below a certain level, the sensor switches off the liste- ning function (to conserve energy for recor- ding) until such time that the energy level is sufficient again for communication. This may occur if many attempts to communicate have been made in a row or because there is insufficient sunlight and/or electrical field.
Should unexplained difficulties occur during communication, it is suggested to wait until another time to make measurements or else install a 9V battery in the sensor.
