tions� The statements made are based on state-of-the-art technology and reflect

our ex-tensive knowledge and many years of experience�

Always carefully read this Operating Manual before beginning any work on

or with the in-strument, especially prior to installation and initial setup! The

Manufacturer shall not be held liable for any damages or malfunctions aris-

ing from a disregard of the warnings and instructions contained herein��

1.3 Copyright

This Operating Manual should be treated as confidential� It is solely intended

for use by persons involved with the instrument� This manual may not be made

available to a third party without prior Manufacturer’s consent� Please contact the

Manufacturer if the need should arise�

2 Safety

This chapter outlines all important safety aspects to be considered for optimum

employee protection and to ensure safe and reliable operations�

2.1 Intended use

The infrared temperature sensor is solely intended for use as described in this

manual� Operational safety can only be ensured when the instrument is used for

its in-tended purpose�

Jede The use of the infrared temperature sensor for any other purpose

beyond what is specified in this manual is prohibited� Using the instrument

in any other manner will be considered as improper�

The Manufacturer/Authorised Agent shall not be held liable for any dam-

ages or loss resulting from such unintended or improper use; in this case

the risk is solely borne by the user�

2.2 User’s responsiblity

The infrared temperature sensor may only be used when it is in perfect working

condition�

2.3 Safety requirements

The instrument operates at low voltage (10 – 34 V DC)� The power supply unit

must conform to directive EN50178, SELV, PELV

2.4 Electromagnetic Compatibility

The instrument complies with the requirements of EC

Directive 89/336/EEC changed by 91/263/EEC; 92/31/EEC; 93/68/EEC relating to

radio interference suppression and electromagnetic compatibility�

European certification:

EN 61000-6-4

EN 61000-6-2

EN 61000-4-2/-3/-4/-6

EN 55011

When connecting a power supply unit, make sure that is also conforms to these

standards� Radio interference may arise if the infrared temperature sensor is

intercon-nected with such peripheral devices which have not been properly

interference-suppressed� This may necessitate additional interference suppression

measures�

3 General Description

The infrared temperature sensor detects temperatures and monitors temperature

ranges without contact�

The sensor detects the infrared energy radiated by a hot object and converts this

to an electric switch signal�

The advantage of this technique is that there is no me-chanical contact between

the sensor and the hot object�

The instrument is suitable for the following applications:

• Measurements at moving or hard-to-reach objects

• Measurements at surface-treated or voltage-carrying objects

• Measurements at sticky materials such as dough or aggressive chemicals

• Applications requiring fast response times�

The rugged stainless steel housing enables the instrument to be used in harsh

industrial environments� The instruments are splash-proof according to IP65 (DIN

40050)� Der Infrarot-Temperatursensor verfügt über einen Analogausgang und

einen Schaltkontakt, der je nach Konfiguration als Öffner oder Schließer verwen-

det werden kann�

4 Function

The infrared temperature sensor measures the temperature without contact to the

target�

The infrared sensor is equipped with an analogue output and an open collector

output� The instrument's display panel shows the measured temperature��

• It generates 2 output signals according to the configured function:

OUT1 Switching threshold

OUT2 Analogue output 4��20 mA

4.1 Switching threshold

OUT1 changes its switching status when the configured upper and lower thresh-

olds (SP1, rP1) are exceeded�

First set the switch point [SP1] in °C or °F� Then set the lower threshold [rP1]�

When you adjust the upper threshold [SP1] the lower threshold [rP1] will change

accordingly� The span remains the same� If [SP1] is lowered to a value where the

span cannot be maintained (as [rP1] would then fall below its minimum value), the

[rP1] is kept with its minimum value� If [SP1] subsequently increases again, [rP1]

also immediately increases�

4.2 Output signal

The following switching functions can be selected:

• Normally open contact: [EF]→[ou1]= Hno (normally open)

• Normally closed contact: [EF]→[ou1]= Hnc (normally closed)

4.3 Upper threshold delay

Once the sensor has detected a temperature which exceeds the switching

threshold [SP1] the time delay [dS1] starts running� When this delay period has

elapsed, the output OUT1 activates switching� This status is sustained until the

lower threshold [rP1] is violated� If this occurs before the time delay has elapsed,

the delay will reset� This function can be used, for example, to suppress spurious

impulse signals at the output�

• Upper threshold delay: [EF]→[dS1] = xs

4.4 Lower threshold delay

To make sure the output impulse is correctly identified, e�g� by a downstream

control system, the output impulse can be lengthened�

• Lower threshold delay: [EF]→[dr1] = xs

4.7 Analogue output

The infrared temperature sensor is equipped with an analogue output OUT2

4...20mA.Themaximumloadis500Ω.DerAusgangsstromistlinearzurgemess-

enen Temperatur� The output current is linear to the measured temperature� Within

the overall measuring range, the required measuring range can be set to °C or °F

using parameter [ASP2] (scale beginning) and parameter [AEP2] (scale end)�

Emissivity of materials:

The infrared temperature sensor reacts to the thermal energy (infrared

radiation) emitted by an object� The ability to radiate heat depends on the

type of material and its surface properties� A description of the calculation

of emissivity is in Chapter 13/ Page 23� The ability of a body to emit infrared

radiation is expressed by a material constant called emissivity coefficient or

just emissivity� This coefficient lies between 0 and 100 %� A body with ideal

radiation (black body) has a coefficient of 100 %� At the same temperature,

bodies with real radiation emit a lower radiation� Therefore, the emissiv-

ity coefficient is < 100%� Um mit dem Infrarot-For this reason, adjust the

emissivity coefficient of the target object on the infrared temperature sensor

to be able to determine the exact temperature� With the configured lower

emissivity coefficient, the infrared temperature sensor automatically com-

pensates for the lower radiation�

• Emissivity: [EF]→[EPS1] = xs

5 Electrical connection

ATTENTION

The infrared temperature sensor 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:
