INFO to baud rate: The factory setting of the baud rate is set to 115 kBd to ensure also at
longer interface cables a working data transfer. For data transmissions with the highest speed,
baud rate and buffer mode must be adjusted (see 7.2.3.4)

4.1.2 Power Supply
With connection to the supply voltage (standard 24 V DC, possible range 18–
30 V) the unit is ready for operation with the factory settings.
By connecting the power supply, the current firmware version is displayed for a
few seconds.
Interrupt the power supply to turn off the pyrometer, e.g. by disconnecting
the connector.
The operating status is displayed on the LED 4:
Orange in the self-test phase (M3 ca. 2 s; H3 during the initialization
and thermostatic phase for ≤ 3 min.)
Green when the pyrometer is ready
Red when an error occurred (see 10.4 Trouble-shooting).
