Cable Colors and Pin Assignment (14 wire connection cables)

The electrical connection of the pyrometer (supply voltage and measuring signal) will be done via the con-
nector on the rear panel. For this purpose, pre-assembled connection cables are available as accessories (see
9.3 Accessories). To prevent accidental short circuits, not used cable wires need to be placed, for example to
the supplied screw terminals.

|NOTICE|
We generally recommend the use of the current 14-wire connection cables. Precaution when
using 12-wire connection cables that were delivered before 2015:
Connection cable for the previous models Metis and Sirius cannot be connected without restrictions on a M3 /
H3 pyrometer!
Old connection cables are bridged in the cable connector to pins E-C and D-F. Connecting such a cable to a
M3 pyrometer, serial interface and analog output 2 and digital input / output 3 are connected and the galvanic
isolation between the outputs is bypassing. Thereby the pyrometer is not destroyed, but the functions are no
longer available. Using such a cable only analog output 1 is available as output.
