Sensor change function
With the menu function Change Sensor, a sensor can be
changed during operation without triggering a fault signal at
the control unit. It also ensures that all sensor data in the
microprocessor can be saved in the sensor memory
(EEPROM) before disconnecting the sensor.
Replacing the sensor
A sensor can be replaced at any time.
1. Select Settings > Sensor > Change Sensor and confirm.
 The maintenance signal is generated on the 4-20mA
interface.
 The display shows Please remove the sensor.
