Electrical Installation
The IS 12-TSP or IGA 12-TSP are powered by a voltage of either 24 V (optional 15 to 40 V DC or
12 to 30 V AC, 48 to 62 Hz). As the instrument is operating with heated and thermostatically
controlled sensors, it needs a warm-up of up to 30 minutes to achieve the maximum accuracy.
But directly after connecting to the power supply the instrument already has a very good
accuracy due to the standard temperature compensation. To switch off the instrument, unplug
the connector or interrupt the power supply.
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
8
,
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.
