3 Controls and Installation
3.1 Electrical Installation
The IS 12-Al is powered by a voltage of either 24 V DC (15 to 40 V DC) or 24 V AC (12 to
30 V AC), 48 to 62 Hz. The instrument has no warm-up time. With connection to the power, the
instrument operates immediately. 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 has to be connected only on the pyrometer side to avoid ground
loops.
LumaSense offers connecting cables; 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 (see
Chapter 10, Reference numbers) and 12 pin angle connector.
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.
For use of the limit contacts, the separate additional cable has
to be used.
