4.1 Cable Colors and Pin Assignment
The electrical connection of the pyrometer (supply voltage and measuring signal) will be done via the
17-pin connector on the device’s rear side. For this purpose, pre-assembled connection cables are
available as accessories (cables 20-wire + shield, with straight connector and optionally with integrated
USB interface converter, see 9.4 Accessories).
Note: The unit has 3 separate circuits: supply, interface and power outputs. The reference potentials
GND should not be connected together. To prevent accidental short circuits, cable wires not in use
should be secured to the supplied screw terminals.

4.1.1 Power Supply
With connection of the supply voltage (standard 24 V DC, possible range 18–
30 V) the unit is ready for operation with the following factory settings (chang-
ing the settings is possible via interface and Software SensorTo ols, see 7).
The supply voltage must be protected with a slow-blow fuse of 800 mA.
Interrupt the power supply to turn off the pyrometer, e.g. by disconnecting the connector.
