3 Safety
This section offers an overview about important safety aspects. Additionally in the several sections there are
concrete safety aspects to avert danger. These aspects are indicated with symbols. Labels and markings at
the instrument have to be noticed and keep 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 already used similar instruments or was already trained by the manu-
facturer.
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 people by mirrors or shiny surfaces.
3.3
Electrical connection
Follow common safety regulations for mains voltage (230 or 115 V AC) connecting additional devices operat-
ing with this mains voltage (e.g. transformers). Touching mains voltage can be fatal. An incorrect 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 series 5 pyrometers are powered by 24 V DC nominal (possible range: 18 to 30 V DC, ripple must be
less than 0.5 V). When connecting the device to the power supply ensure correct polarity. The instrument
has no warm-up time, with connection to the power the instrument operates immediately, but still needs 15
or 30 min (depending on the type, see technical data) to achieve its full accuracy. To switch off the instru-
ment, 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 connecting cable
has wires for power supply, interface, analog output, external laser switch and external clear of maximum
value storage via contact (see section 15, Reference numbers) and 12 pin 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.
