The submenu » Sensor « can be used to make various settings for the
installed sensor.
Change sensor
— This function can be used to change a sensor while the unit is running with-
out sending a fault alarm to the control unit. It also ensures that all sensor
data currently in the microprocessor can be saved to the EEPROM of the
sensor before the sensor plug is disconnected.
— In principle, a sensor can be replaced at any time. However, for technical
safety reasons, a fault alarm will be activated until a new sensor is connect-
ed, in case a sensor is disconnected accidentally.

— The maintenance signal on the analogue interface remains until the sensor
operates normally.
The duration of the warming-up period depends on the type of sensor and
its history. If, for example, the sensor had already been warmed up on an-
other transmitter and it was disconnected only for a short time, the warm-
ing-up period may be shorter than that shown in the operating instructions
for the sensor.
See the operating instructions for the sensor for the maximum warming-up
period.
If the old sensor is replaced with an identical sensor (with the same Part
No.), the configuration of the transmitters (gas type, measuring range, cal-
ibration gas, calibration interval) remains unchanged.
Otherwise, the default values for the sensor (see the operating instructions
