3 Controls and Installation
3.1 Electrical Installation
The pyrometer is powered by 24 V DC ± 25% (very well stabilized, ripple max. 50 mV). It is
important to ensure correct polarity when connecting the device to the power supply.
To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used.
LumaSense offers connecting cables, which are not part of the standard scope of delivery.
The shield of the connecting cable has to be connected only on the pyrometer’s side. If the
connecting cable is extended, the shield of the extension also needs to be extended. The shield
must be open on the power supply side (switch board), to avoid ground loops.
The connecting cable has wires for the power supply, interface, analog output, external laser
switch, and external clear of maximum value storage via contact and 12 pin connector. The cable
includes a short adapter cable with a 9-pin D-SUB connector. This connector may be used in
combination with the RS485 to USB adapter.
Once the instrument has been connected to the power supply, it is immediately ready for use.
Although it does not need to be warmed up, it does need to run for approximately 15 to 30
minutes before achieving full accuracy. The instrument can be switched off by interrupting the
power supply or unplugging the electrical connector.
Attention: When connecting the power supply, ensure the polarity is correct.
