Maintenance
● Check sensor function.
— If an identical sensor (sensor with the same Part No.) was previously installed, the
complete configuration of the transmitter remains unchanged. Otherwise, the
transmitter is configured with the default values (see the operating instructions for
the sensor).
See also » Sensorlock «, page 76.
Disposal of electrochemical sensors:
— Sensors must be disposed of as special waste.
Note the relevant waste disposal regulations.
Further information can be obtained from the relevant local authority and from ap-
propriate waste disposal companies.
Sensor-diagnosis function
This function is active only if the Polytron 7000 is equipped with a sensor diagnosis
dongle (Part No. 83 17 860).
— Extended sensor self-test function, taking such things as the temperature, gas
monitoring and remaining sensitivity into account.
— During normal operation, the sensor status is indicated by the sensor-diagnosis
icon in the display:
Caution:
— Do not throw sensors into the fire – explosion hazard.
— Do not open sensors forcibly – risk of caustic burns.
The sensor is ready
The sensor is ready, but is approaching the end of its operating lifetime
The sensor is still ready, but it should be replaced as soon as possible
