Electrical Installation
The IN 5/9 plus pyrometer is powered by a voltage of 24 V DC (possible range 18 ... 30 V). Once
connected to power, the instrument operates immediately and needs no warm-up time. To
switch off the instrument, unplug the connector.
To meet the electromagnetic requirements, a shielded connecting cable must be used. The
shield of the connecting cable must be connected only on the pyrometer side to avoid ground
loops.
LumaSense offers connecting cables, but they are not part of standard scope of delivery. The
main connecting cable has wires for power supply, interface, analog output, external laser
switch and external clear of maximum value storage via contact and 12 pin angle connector (see
Chapter
10
,
Reference numbers
). The cable includes a short RS232 adapter cable with a 9 pin
SUB-D connector for direct PC communication. This adapter is not used in combination with
RS485 interface.

3.1.2
Connecting the pyrometer to a PC
The pyrometers are equipped with a serial interface RS232. Only one pyrometer can be
connected on the standard PC RS232 interface. Only short distances can be transmitted with
RS232 and electromagnetic interferences can affect the transmission.
The pyrometer can also be equipped with an RS485 serial interface (on request). With the RS485,
long transmission distances can be realized, and the transmission is, to a large extent, free of
problems. The RS485 also allows several pyrometers to be connected in a bus system.
If an RS485 connection is not available at the PC, it can be accomplished using an RS485 or RS232
to USB connector. When using a RS485 to USB adapter, make sure that the adapter is fast
enough to receive the pyrometer’s answer to an instruction of the master. Most of the
