Electrical connection
The pyrometer is supplied with low voltage 24V DC (18 ... 32V DC).
The pyrometer may only be installed by a skilled, qualified
electrician. Do not connect the instrument while the voltage
supply source is turned on. Please observe international
safety regulations at all times
► Switch to neutral and verify absence of voltage
► Connect the instrument according to the following schematic.
PIN 1 WH (white) L+ (Power supply 24V DC)
PIN 2 BN (brown) Digital in- / out 1
PIN 3 GN (green) Analogue output 2/ analogue input
PIN 4 YE (yellow) Analogue output 1
PIN 5 GY (grey) Serial interface RS 485 (A) /Tx-/D-)
PIN 6 PK (pink) Serial interface RS 485 (B) /Tx+/D+)
PIN 7 BU (blue) Digital in- / output 2
PIN 8 RD (red) L- (GND)
The pyrometer must be protected against high voltage and strong
electromagnetic fields. Use a shielded cable. The shield must be
connected with the connector housing.
Use a flyback diode when switching inductive loads.
Installation
Install the pyrometer in a location where it will not be unnecessarily ex-
posed to smoke, ambient heat or water vapour.

Laser safety instructions
Class 2 Laser Product
●
Never look directly into the laser beam path (emitted power <1.0
mW at a wavelength of 630-670 nm)
●
Do not leave the instrument unattended when the laser is activated.
●
Do not point the laser beam at any person.
●
During pyrometer installation and alignment, make sure to avoid
the possibility of laser light reflections caused by reflective sur-
faces.
● All currently valid laser safety standards must be observed.
Laser Warning Label
The black and yellow laser warning label is affixed next to the nameplate
of the instrument. An arrow indicates the laser emission path (lens open-
ing).
