3 Safety
This section offers an overview about important safety aspects.
Additionally in the several sections there are mandatory safety aspects to avert danger. These aspects are
indicated with symbols. Labels and markings at the instrument have to be observed and kept in a permanent
readable condition.
3.1
General
Each person working with the pyrometer must have read and understood the user manual before operation.
Also this has to be done if the person has already used similar instruments or was already trained by the
manufacturer.
The pyrometer has only to be used for the purpose described in the manual. It is recommended to use only
accessories offered by the manufacturer.
3.2
Laser targeting light
For easy alignment to the measuring object the pyrometers can be equipped with a laser targeting light. This
is a visible red light with a wavelength between 630 and 680 nm and a maximum power of 1 mW. The laser
is classified as product of laser class II.
Warning: To reduce the risk of injury to the eyes, do not look directly into the
targeting laser and do not point the targeting laser into anyone's eyes.
The instrument is equipped with a class II laser that emits radiation.
Safety regulations:
• Never look directly into the laser beam. The beam and spot can be watched safely from side.
• Make sure that the beam will not be reflected into eyes of persons by mirrors or shiny surfaces.
3.3
Electrical connection
Follow common safety regulations for mains voltage (e.g. 230 or 115 V AC) connecting additional devices
operating with this mains voltage (e.g. transformers). Touching mains voltage can be mortal. A non expert
connection and mounting can cause serious health or material damages.
Only qualified specialists are allowed to connect such devices to the mains voltage.
4 Electrical Installation
The ISR 12-LO and the IGAR 12-LO are powered by a voltage of 24 V DC (15 to 40 V DC) or 24 V AC
(12 to 30 V AC). As the instrument is operating with heated and thermostatically controlled sensors, it needs
a warm-up of up to 5 minutes (during this warm-up period the LED display indicates “7777“), after that the
instrument is ready for use. To switch off the instrument, interrupt the power supply or unplug the electrical
connector.
To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used. The shield of
the connecting cable has to be connected only on the pyrometer’s side. On side of the power supply (switch
board) the shield must be open 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 maxi-
mum value storage via contact (see section 15, Reference numbers) and 12 pin connector. The cable in-
cludes 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.
