5.10 Settings sensor
5.10.1 Sensor change
With this function, a sensor can be changed during operation
without triggering a fault signal at the central controller. It also
ensures that all sensor data in the microprocessor can be
saved in the sensor memory (EEPROM) before disconnecting
the sensor.
A sensor can be changed at any time. However, for safety
reasons a fault alarm is generated when the sensor is
disconnected until a new sensor is connected.
1. Select Settings > Sensor > Sensor change and confirm.
The maintenance signal is generated on the analog
interface, the following display shows: "Please remove the
sensor".
2. Replace the old sensor with a new sensor, see Section 6.4
on Page 35.
When the new sensor is installed:
Display: "Loading data, please wait".
When the sensor data are loaded:
Display: "Data loaded".
3. Select Back to menu and confirm.
The maintenance signal on the analog interface remains
pending until the sensor is warmed-up.
The warm-up time depends on the type of sensor and its
history. For example, if the sensor has already warmed-up on
another instrument and the operation was only interrupted for
a short time, the warm-up time can be shorter than the time
specified in the Instructions for Use for the sensor.
Maximum warm-up time of a new sensor: see the Instructions
for Use for the sensor or Section 10.1 on Page 38 for Oxygen:
EN 50104 approvals.

If a sensor of the same type (same part number) was
previously
installed,
configuration is retained (gas type, measurement
range, test gas, calibration interval, etc.)
Otherwise the factory default settings of the new
sensor (see Instructions for Use for the sensor) are
uploaded and will overwrite the instrument specific
configuration.
This can be prohibited if the sensor lock function (see
Section 5.10.4 on Page 27) is activated.

5.10.3 Sensor test
This function is only active for Polytron 8100 using the EC
sensor.
This function is only active if the sensor test or diagnostics
dongle is installed.
This function activates the sensor test. The instrument
routinely checks the sensor for proper function. If the sensor
does not pass the self-test, a warning or fault message will be
issued.
1. Select Settings > Sensor > Sensor test and confirm.
2. Select Enable or Disable and confirm.
5.10.4 Sensor lock
This function activates the sensor lock feature.
1. Select Settings > Sensor > Sensor lock and confirm.
2. Select On or Off and confirm.
CAUTION
!
If
the instrument will reject any sensor
turned
whose part number does not match the
On
part number of the previously installed
sensor.
If
the instrument will accept any suitable
turned
sensor, uploading the default settings of
Off
this sensor. However, this will overwrite
any customized settings with the default
settings of the new sensor.
5.10.5 Sensor type
This function is only active for Polytron 8200 or Polytron 8310
using the DD, LC or DSIR sensor.
