2 Safety
2.1 Use of the Manual
▪Any person who is going to work with the device must have read and understood the operating manual be-
fore beginning.
▪Operation and maintenance of the system is only to be performed by trained personnel.
▪This operating manual is to be kept and passed on.
2.2 Supplementary Information about the Operation
The following symbol is used to simplify the search for useful information:
INFO indicates useful tips, recommendations and information for efficient and trouble-free operation.
2.3 Warning Notes
The following symbols are used in this manual and, if applicable, on the device as a mark for information, re-
strictions, preventive measures and security notes. This information indicates risks and how they can be
avoided.
Please pay attention to these symbols for safety reasons.
CAUTION The hazard symbol with the signal word CAUTION on a yellow background indicates a haz-
ardous situation which, if not avoided, could result in minor or moderate injury.

2.4 Safety Labels / Symbols
In addition to the warning notes used in this manual, the following warning symbols are used. Warning symbols
can also be found on the device. Follow all measures marked with the label to avoid injury.
Indicates general hazards.
Indicates the hazard for the eyes from op-
tical radiation.
Indicates the hazard for the eyes due to
a class 2 laser targeting light.
Indicates the hazard of automatic startup
of machine parts.
2.5 Device Labels
On the top of the pyrometer there is the label (nameplate) as well as a warning sticker for IR sensors with a
laser targeting light.
▪Mount the device in a manner that the labels are still clearly visible after installation.
▪Keep the warning signs in legible condition
▪Replace damaged labels
2.6 Identification Label
The identification label on top of the device shows information to:
▪Distributor logo
▪Series / order number (for breakdown see chap. 9.2)
▪Temperature range, serial number, serial interface(s), analog output and
power supply
▪CE sign and crossed-out waste container product mark (see 1.8 Disposal)
▪Manufacturing company.
2.7 Laser Targeting Light
For easy alignment, the pyrometers may be equipped with a laser target-
ing light, laser class 2 (according to IEC 60825-1). The laser emits a visi-
ble red light with a power of <1 mW and a wavelength around 650 nm.
SAFETY INSTRUCTIONS
▪Never look into the direct or reflected laser beam.
▪Do not point the laser to anyone.
▪If laser radiation hits the eye, avert one's eyes immediately.
2.8 Through-lens Sighting
Devices with through-lens sighting and temperature range above 1400°C are equipped with an adjustable eye
protection filter in the eyepiece to reduce glare at high measurement temperatures. The unprotected look at
temperatures >1400°C can damage eye function permanently.
SAFETY INSTRUCTIONS
▪Only look with darkened eyepiece at objects with temperatures above 1400°C / 2552°F to protect the eyes
against glare at high radiation temperatures.
▪Before looking at the high temperatures, always first adjust the eyepiece by turning it to the darkest position.

2.9 Electrical Connection
When connecting or working on the main voltage, general safety guidelines must be observed, e.g. when con-
necting power transformers. Touching supply voltage can be lethal. Improper installation can cause serious
injury or physical damage. Only qualified personnel are allowed to work with the main voltage.
We recommend our wiring box accessory-this is a fully assembled connection set for Process Sensors pyrom-
eters.
2.10 Responsibility of the Operators / Process Responsibility
If the device is used in the commercial sector the operator is subject to the legal responsibilities for workplace
safety.
In addition to the safety instructions in this manual, please follow safety, accident prevention, and environmen-
tal protection regulations. If the device is integrated into a system, the safety of the system in which the device
is integrated is in the responsibility of the installer of the system.
Process Sensors Corporation does not guarantee that the temperature control in all processes will meet the
desired requirements. Process Sensors Corporation excludes the process responsibility.
3 Overview
3.1 Intended Use
The herein described 2-color pyrometers Metis M3 are devices for non-contact temperature measurement.
With its short-wave spectral range they are suitable for measurements on metals, ceramics, graphite etc. with
temperature ranges depending on the model execution between 300 and 3300°C (M3) or 350 and 3300°C
(H3). M3 models have a response time of < 1 ms, H3 high-speed models have a response time < 80 µs.
3.2 Scope of Delivery
Pyrometer, software SensorTools, works certificate, user manual

4 Electrical Connection
4.1 Cable Colors and Pin Assignment (14 wire connection cables)
The electrical connection of the pyrometer (supply voltage and measuring signal) will be done via rear panel
connector. For this purpose, pre-assembled connection cables are available as accessories (see 9.3 Accesso-
ries). To prevent accidental short circuits, unused cable wires need to be placed, for example to the supplied
screw terminals.

|NOTICE|We generally recommend the use of the current 14-wire connection cables. Precaution when
using 12-wire connection cables that were delivered before 2015: Connection cable for the previous models
Metis and Sirius cannot be connected without restrictions on a M3 / H3 pyrometer!
Old connection cables are bridged in the cable connector to pins E-C and D-F. Connecting such a cable to a
M3 pyrometer, serial interface and analog output 2 and digital input / output 3 are connected and the galvanic
isolation between the outputs is bypassing. Thereby the pyrometer is not destroyed, but the functions are no
longer available. Using such a cable only analog output 1 is available as output.
