1. Safety Instructions
This document contains important information, which should be kept at all times with the
instrument during its operational life. Other users of this instrument should be given these
instructions with the instrument. Eventual updates to this information must be added to the
original document. The instrument can only be operated by trained personnel in accordance
with these instructions and local safety regulations.
Acceptable Operation
This instrument is intended only for the measurement of temperature. The instrument is
appropriate for continuous use. The instrument operates reliably in demanding conditions, such
as in high environmental temperatures, as long as the documented technical specifications for
all instrument components are adhered to. Compliance with the operating instructions is
necessary to ensure the expected results.
Unacceptable Operation
The instrument should not be used for medical diagnosis.
Replacement Parts and Accessories
Use only original parts and accessories approved by the manufacturer. The use of other
products can compromise the operation safety and functionality of the instrument.
Instrument Disposal
Disposal of old instruments should be handled according to professional and
environmental regulations as electronic waste.
Operating Instructions
The following symbols are used to highlight essential safety information in the operation
instructions:
Helpful information regarding the optimal use of the instrument.
Warnings concerning operation to avoid instrument damage and personal injury.
The instrument can be equipped with a Class 2 laser. Class 2 lasers shine only
within the visible spectrum at an intensity of 1 mW. Looking directly into the laser
beam can produce a slight, temporary blinding effect, but does not result in physical
injury or damage to the eyes, even when the beam is magnified by optical aids. At
any rate, closing the eye lids is encouraged when eye contact is made with the laser
beam. Pay attention to possible reflections of the laser beam. The laser functions
only to locate and mark surface measurement targets. Do not aim the laser at
people or animals.
Pay particular attention to the following safety instructions.
Use in 115/230 V~ electrical systems can result in electrical hazards and personal
injury, if not properly protected. All instrument parts supplied by electricity must be
covered to prevent physical contact and other hazards at all times.

2. Product Description
The Endurance® Series of instruments consist of 1-Color (monochrome) and 2-Color (ratio)
infrared noncontact temperature measurement systems with variable focus, through-the-lens
sighting, and parallax-free optics. They are energy transducers designed to measure accurately
and repeatedly the amount of heat energy emitted from an object, and then convert that energy
into a measurable electrical signal. Temperature measurements can be taken using either of
the following modes:

1-Color mode (monochrome) – for standard temperature measurements. The 1-color
mode is best for measuring the temperature of targets in areas where no sighting
obstructions, either solid or gaseous, exist. The 1-color mode is also best where the
target completely fills the measurement spot.

2-Color mode – temperatures are determined from the ratio of two separate and
overlapping infrared bands. The 2-color mode is best for measuring the temperature of
targets that are partially obscured (either intermittently or permanently) by other objects,
openings, screens, or viewing windows that reduce energy, and by dirt, smoke, or steam
in the atmosphere. The 2-color mode can also be used on targets that do not completely
fill the measurement spot, provided the background is much cooler than the target.
Each model operates as an integrated temperature measurement subsystem consisting of
optical elements, spectral filters, detector, digital electronics and an IP65 (NEMA-4) rated
housing. Each is built to operate on a 100 percent duty cycle in industrial environments. Various
output types are offered for easy integration into industrial monitoring and control environments.
The following Endurance® series model variants are available, including the several sighting,
cooling and communication options.
1-Color (monochrome) models: E1ML, E1MH, E2ML, E2MH, E3ML, E3MH
2-Color (ratio) models: E1RL, E1RH, E2RL

2.1. Theory of Operation for 2-Color Sensors
Two-color ratio technology makes possible accurate and repeatable temperature
measurements that are free from dependence on absolute radiated energy values. In use, a 2color sensor determines temperature from the ratio of the radiated energies in two separate
wavelength bands (colors).
The benefits of 2-color sensors are that accurate measurements can be made under the
following conditions:



When the field of view to the target is partially blocked or obscured.
When the target is smaller than the sensor’s field of view.
When the target emissivity is low or changing by the same factor in both wavelength
bands.
Another benefit is that 2-color sensors measure closer to the highest temperature within the
measured spot (spatial peak picking) instead of an average temperature. A 2-color sensor can
be mounted farther away, even if the target does not fill the resulting spot size. The convenience
is that you are not forced to install the sensor at some specific distance based upon target size
and the sensor’s optical resolution.
2.1.1. Partially Obscured Targets
The radiated energy from a target is, in most cases, equally reduced when objects or
atmospheric materials block some portion of the optical field of view. It follows that the ratio of
the energies is unaffected, and thus the measured temperatures remain accurate. A 2-color
sensor is better than a 1-color sensor in the following conditions:





Sighting paths are partially blocked (either intermittently or permanently).
Dirt, smoke, or steam is in the atmosphere between the sensor and target.
Measurements are made through items or areas that reduce emitted energy, such as
grills, screens, small openings, or channels.
Measurements are made through a viewing window that has unpredictable and
changing infrared transmission due to accumulating dirt and/or moisture on the window
surface.
The sensor itself is subject to dirt and/or moisture accumulating on the lens surface.
1-color sensors see polluted atmosphere and dirty windows and lenses as
a reduction in energy and give much lower than actual temperature
readings!
2.1.2. Targets Smaller Than Field of View
When a target is not large enough to fill the field of view, or if the target is moving within the
field of view, radiated energies are equally reduced, but the ratio of the energies is unaffected
and measured temperatures remain accurate. This remains true as long as the background
temperature is much lower than the target’s. The following examples show where 2-color
sensors can be used when targets are smaller than the field of view:


Measuring wire or rod — often too narrow for field of view or moving or vibrating
unpredictably. It is much easier to obtain accurate results because sighting is less
critical with two-color sensors.
Measuring molten glass streams — often narrow and difficult to sight consistently with
single-wavelength sensors.
2.1.3. Emissivity and 1-color (single wavelength) measurements
Emissivity is a calculated ratio of infrared energy emitted by an object to the energy emitted by
a blackbody at the same temperature (a perfect radiator has an emissivity of 1.00). The
5
Endurance® Series
Users Manual
emissivity is preset at 1.00. For information on determining an unknown emissivity, and for
sample emissivities, refer to the appendix of this manual.
When target emissivity is uncertain or changing, a 2-color sensor can be more accurate than a
1-color instrument as long as the emissivity changes by the same factor in both wavelength
bands. Accurate measurement results are dependent on the application and the type of
material being measured. The emissivity of all real objects changes with wavelength and
temperature, at varying degrees, depending on the material. To determine how to use 2-color
sensors with your application when uncertain or changing emissivities are a factor, please
contact our sales representative or technical support department.
2.1.4. Slope (2-color ratio) measurements
The slope is the quotient of the emissivities based on the narrow and the wide spectral range
(first and second wavelength). The slope is preset at the factory at 1.000.
For information on determining an unknown slope, and for sample slopes, refer to the appendix
of this manual.
The slope is the important parameter for measurements in 2-color mode!
The emissivity affects only measurements in 1-color mode.

For 1-color temperature measurements make sure the target completely fills the measurement
spot. The target spot size for a properly focused target with the given distance to the target can
be determined by using the following formula under Figure 2.
Divide the distance (D, in Figure 2) by the D:S specification to get the target spot size.

4. Environment
Sensor location and configuration depends on the application. Before deciding on a location,
you need to be aware of the ambient temperature at the location, the atmospheric quality at the
location (especially for 1-color temperature measurements), and the possible electromagnetic
interference at the location. If you plan to use air purging, you need to have an air connection
available. Also, wiring and conduit runs must be considered, including computer wiring and
connections, if used. The following subsections cover topics to consider before you install the
sensor.
4.1. Ambient Temperature
The sensing head is designed to operate in ambient temperatures between 0°C (32°F) and
60/65°C (140/149°F). The internal ambient temperature can vary from 10°C (50°F) to 72°C
(162°F). Internal temperatures outside this range will cause a failsafe error. In ambient
conditions above 60/65°C (140/149°F), an optional air/water cooled housing is available to
extend the operating range to 120°C (250°F) with air-cooling, or 175°C (350°F) with water
cooling. When using the water-cooled housing, it is strongly recommended to also use the air
purge collar to avoid condensation on the lens. In ambient conditions up to 315°C (600°F), the
ThermoJacket accessory should be used.
When using air or water-cooling with air purging, make sure air and water supplies are installed
before proceeding with the sensor installation.
Water and air temperatures for cooling should be 15-30°C (60-86°F) for best performance.
Chilled water or air below 10°C (50°F) is not recommended. For air purging or air cooling, clean
(filtered) or “instrument” air is recommended.
4.2. Atmospheric Quality
Smoke, fumes, dust, and other contaminants in the air, as well as a dirty lens are generally not
a problem when using the 2-color mode (as long as the attenuation is equal in both spectral
bands). However, if the lens gets too dirty, it cannot detect enough infrared energy to measure
accurately, and the instrument will indicate a failure. It is good practice to always keep the lens
clean. The Air Purge Collar helps keep contaminants from building up on the lens.
If you use air purging, make sure an air supply with the correct air pressure is installed before
proceeding with the sensor installation.

4.3. Electrical Interference
To minimize electrical or electromagnetic interference or “noise” be aware of the following:





Mount the electronics enclosure as far away as possible from potential sources of
electrical interference such as motorized equipment producing large step load
changes.
Use shielded wire for all input and output connections.
Make sure the shield wire from the electronics to terminal block cable is earth grounded.
For additional protection, use conduit for the external connections. Solid conduit is
better than flexible conduit in high noise environments.
Do not run AC power for other equipment in the same conduit.
5. Installation
5.1. Mechanical Installation
After all preparations are complete, you can install the sensor.
How you fix the sensor depends on the type of surface and the type of bracket you are using.
As noted before, all sensors, whether standard or with the air/water-cooled housing option,
come with a fixed bracket (E-FB) and a mounting nut (E-MN). You are able to fix the sensor by
a bracket of your own design, or by one of the available supplier furnished mounting
accessories, see section 9 Accessories, page 51. If you are installing the sensor in a
ThermoJacket accessory, you should use the appropriate mounting device. In such case,
please refer to the ThermoJacket manual for further details. There is no specific focusing tool
accessory for the Endurance® sensor available. The Endurance® sensor needs to be manually
focused before the installation inside a ThermoJacket or before attaching an air purge collar.
5.1.1. Distance to Object
Endurance® sensor placement may vary to suit the application. The following sections
demonstrate the sensor placement under various conditions, where 1- or 2-color temperature
measurements deliver reasonable readings.
When installing the sensor, check for any high-intensity discharge lamps or
heaters that may be in the field of view (either background or reflected on a
shiny target)! Reflected heat sources can cause a sensor to give erroneous
readings.
5.1.2. Sensor Placement (1-Color Mode)
Sensor placement for 1-color temperature measurements is more critical than for 2-color
measurements. The sensor must have an unobstructed view to the target. Any obstruction on
the lens, the front window, or in the atmosphere influences the temperature reading accuracy.
The sensor distance to the target can be anywhere beyond the minimum requirements, as long
as the target completely fills the field of view.

The following figure demonstrates the sensor placement under various conditions, where valid
2-color temperature measurements are possible. Note, however, that if the sensor signal is

5.1.5. Aiming and Focusing
Once you have the sensor in place, you need to aim and focus it on the target. To aim and
focus the sensor, complete the following:
1. Loosen the nuts or bolts of the mounting base. (This can be either a factory-supplied
accessory or customer-supplied base.)
2. Look through the eyepiece and position the sensor so the target is centered as much as
possible in the middle of the reticle, see Figure 8. (Note that the target appears upside
down.)
3. Turn the lens holder clockwise or counter-clockwise until the target is in focus. You can
tell the lens is focused correctly by moving your eye from side to side while looking
through the eyepiece. The target should not move with respect to the reticle. If it does,
keep adjusting the focus until no apparent motion is observed.
4. Check again to be sure the target is still centered, and secure the mounting base.
Focusing is complete.

When focusing the sensor, do not depend on the clarity of the image
through the eyepiece to determine the focus. Use the “move the eye”
technique described in step 3 above. If the desired focus distance is known
in advance, this focusing can be conveniently done in the office
environment before installation.

An Endurance® specific terminal block is available to attach the 12-wire color-coded sensor
cable via the terminal block to the process world.
Figure 15: Endurance® series labeled terminal block
5.2.4. Power Supply
Connections from a nominal 24VDC (500 mA or higher) power supply attach to the appropriate
terminals on the electronic enclosure’s terminal strip.
Isolated power is required, and the appropriate manufacturer supplied
power supply accessory provides this. Beware of use of other power
supplies, which may not provide the necessary isolation and could cause
instrument malfunction or damage!
5.2.5. Computer Interfacing via RS485 link
The distance between the sensor and a computer can be up to 1200 m (4000 ft.) via RS485
interface. This allows ample distance from the harsh environment where the sensing system is
mounted to a control room or pulpit where the computer is located. The USB/RS485 Interface
Converter allows you to connect your Endurance® sensor to computers by using an USB
interface.
With auto configuration, the converter is able to automatically configure RS485 signals without
external switch setting. The converter is equipped with 3000 VDC of isolation and internal
surge-protection to protect the host computer and the converter against high voltage spikes, as
well as ground potential difference. When the converter is connected the computer gets one
virtual COM port.

Just the 2-wire (half duplex) communication is supported on the Endurance® sensor side. The
disadvantage is that the data transfer is just alternating possible in one direction at a time. The
maximum communication baud rate between the Endurance® device and the USB/RS485
converter is 115.200 kBaud. A Baud rate of 38.4 kBaud is the default (preset) value in the
Endurance® series device during factory setup.
Just the 2-wire (half duplex) mode is supported by the Endurance® devices
in serial RS485 communication!
Figure 16: USB/RS485 Converter
Multiple Endurance® sensors in a RS485 Multidrop Network Wiring
For an installation of two or more Endurance® sensors in a RS485 network (2-wire, half duplex),
each Endurance® sensor needs it’s specific RS485 network address (1 - 32), preset via the
Endurance® control panel (user interface) or alternatively via a standard terminal program
(operating system dependent). Once all the units are addressed, wire up the units in the 2-wire
multidrop manner, whereas all A-signals, as well all B-signals have to be connected to common
lines. The common A-signals have to be routed to the TX+ and the common B-signals to TXterminal at the selected USB/RS485 converter.
5.2.6. Addressing the Endurance® sensor in a RS485 Multidrop Network
If you are installing two or more sensors in a multi-drop configuration, please be aware of the
following:
 Each sensor must have a unique address greater zero (1 - 32).
 Each sensor must be set to the same baud rate (default is 38.4 kBaud).
 Once all the units are addressed, wire up the units in the 2-wire multidrop manner,
keeping all A & B to be common.
 Now you can run the supplied Endurance® software, an own written communication
software or an individual terminal program to access the Endurance® sensor for issuing
commands and receive the responses.

6. Device Control
Once you have your sensor(s) positioned and connected properly, the system is ready for
continuous operation. Nonstop operation of the Endurance® device is achieved either by back
panel operation or through software control via the RS485, the LAN/Ethernet or PROFINET IO
communication interface. The Endurance® software, a MS-Windows based setup and
configuration program is supplied with your sensor. You can also create custom programs using
the communication protocols listed in section 10, Programming Guide.
6.1. Control Panel
The Endurance® sensor is equipped with a control panel, which is the manually operated user
interface and consists of two display types, one alarm and one status LED and several
setting/controlling buttons, as shown in
Figure 17. The panel is primarily for setting up the instrument prior to nonstop operation. A
screwable end cap with a sealed glass window protects the user interface during nonstop
operation. You are able to configure sensor settings via the control panel or remotely via a
computer or a programmable logic controller.
The sensor has a remote locking feature to protect the unit from accidental interaction over the
control panel. This lockout mode denies access to the submenu functions of the control panel.
Via the RS485, the LAN/Ethernet, the PROFINET IO communication interface or a specific key
command over the control panel, the Endurance® device can be unlocked.

7. Signal Processing
The activation and modification of signal processing functions and their associated
parameters is possible via the PC based Endurance® software, serial LAN or RS485
programming commands, or over the rear control panel (Endurance® user interface).
7.1. Averaging
Averaging is to smooth the output signal. The output signal smooth algorithm depends on the
defined time basis. The output signal tracks the detector signal with significant time delay in
which noise and short peaks will be smoothend. A longer average time smoothens the damping
behavior. The average time is the amount of time the output signal needs to reach 90%
magnitude of an object temperature jump. The range for the average time can be set from 0.1
to 300.0 seconds, whereas just 0.1 - 299.9 seconds will be interpreted as averaging duration.
A value of 300.0 seconds indicates that averaging post processing depends on an external
trigger signal. A low-level input signal (pull to GND) at the external input (Trigger) will promptly
interrupt the averaging and will restart the average calculation with the current temperature
reading.

Figure 28: Averaging
Attention: The disadvantage of averaging is the time delay of the output signal. If the
temperature jumps at the input (hot object), the output signal reaches only 90% magnitude of
the actual object temperature after the defined average time.
Once Averaging is set above 0, it automatically activates. Note that other hold functions (like
Peak Hold or Valley Hold) do not work concurrently.
7.2. Peak Hold
The output signal follows the object temperature up to the point, where a new maximum is
detected. The output will hold the maximum temperature value for the preset duration of the
peak hold time. Once the peak hold time expires, the peak hold function will reset and the output
will resume tracking the object temperature until a new peak is reached. The range for the peak
hold time can be set from 0.1 to 300.0 seconds, whereas just 0.1 - 299.9 seconds will be
interpreted as peak hold duration. A value of 300.0 seconds indicates that peak hold post
processing depends on an external trigger signal. A low-level input signal (pull to GND) at the
external input (Trigger) will promptly interrupt the peak hold function and restarts the peak
holding with the current temperature reading.
7.2.1. Reset Peak Hold by Peak Hold Time expiration
Once the Peak Hold Time is set between 0.1 until 299.9 seconds, it automatically activates.
The post-processed peak hold value stays the same up to the following happens:
36
Innovative High Temperature Infrared Pyrometers
Error! Use the Home tab to apply Überschrift 1 to the text that you want to appear here.

The Peak Hold Time is expired after holding the last peak value. In this case, the signal
reverts to the current object temperature reading and restarts the peak holding process
with the given hold time.

The current object temperature reading exceeds the last temperature peak value. In
this case, a new peak reading starts with holding the new peak object temperature.

7.2.2. Reset Peak Hold by external Trigger signal
Once the Peak Hold Time is set to 300 seconds, the peak holding process will be activated by
an external trigger input signal (Trigger  high). The post-processed peak hold value stays the
same up to the following happens:

The external trigger input signal is pulled down (Trigger  GND). In this case, the signal
reverts to the current object temperature reading and deactivates the peak hold
function as long as the external trigger signal stays pulled to GND.

The current temperature reading exceeds the peak hold temperature. In this case, a
new peak reading starts with holding the new peak. No time limit is active for holding
the last peak temperature.

Note that other signal processing functions (like Averaging or Valley Hold) do not work

7.2.3. Signal Slope (decay) in case of Peak Hold Reset
Three different signal drop (decay) functionalities are implemented and may be activated by
the PC based Endurance® software, serial LAN or RS485 programming commands, or over
the rear control panel (Endurance® user interface). Via the control panel is just an entry field
given to set the linear signal slope (decay).
7.2.3.1.Perpendicular signal drop (default mode)
The default mode (perpendicular signal drop) is activated, if both relevant signal decay values
(linear decay & averaging decay) are set to zero (0.0 Kelvin/second). This can be achieved via
the PC based Endurance® software, serial LAN or RS485 programming commands, or over
the rear control panel (Endurance® user interface).

The signal drop follows a linear decay function, where the decay value is given in Kelvin/second.
The linear decay value is settable via the PC based Endurance® software, a serial LAN or
RS485 programming command <XE>, or over the rear control panel (Endurance® user
interface).

7.2.3.3.Average time dependent signal drop (averaging mode)
The signal drop follows an averaging time function. The average time is the amount of time the
output signal needs to reach 90% magnitude compared to a perpendicular drop. This parameter
is set by means of the programming command <AA>.

7.3. Advanced Peak Hold
This function searches the sensor signal for a local peak and writes this value to the output
until a new local peak is found. Before the algorithm restarts searching for a local peak, the
object temperature has to drop below a predefined threshold. If the object temperature raises
above the held value which has been written to the output so far, the output signal follows the
object temperature again. If the algorithm detects a local peak while the object temperature is
currently below the predefined threshold the output signal jumps to the new maximum
temperature of this local peak. Once the actual temperature has passed a peak above a
certain magnitude, a new local peak is found. This magnitude is called hysteresis.
The threshold is set by means of the programming command <C>, for hysteresis use the
command <XY>.

7.4. Valley Hold
This function works similar to the peak hold function, except it will search the signal for a
minimum. The output signal follows the object temperature until a minimum is reached. The
output will hold the minimum temperature value for the selected duration of the valley hold
time. Once the hold time is expired, the valley hold function will reset and the output will
resume tracking the object temperature until a new valley is reached. The range for the valley
hold time can be set from 0.1 to 300.0 seconds, whereas just 0.1 - 299.9 seconds will be
interpreted as valley hold duration. A value of 300.0 seconds indicates that valley hold post
processing depends on an external trigger signal. A low level input (GND) at external input

(Trigger) will promptly interrupt the valley hold function and restarts the valley holding with the
current temperature reading.

Once Valley Hold is set above 0, it automatically activates. The output signal remains the same
until one of two things happens:

The valley hold time runs out. In this case, the signal reverts to actual temperature.

The actual temperature goes below the hold temperature. In this case, starts holding
new valley.
Note that other signal processing functions (like Averaging or Peak Hold) do not work
concurrently with Valley Hold.
7.5. Advanced Valley Hold
This function works similar to the advanced peak hold function, except it will search the signal
for a local minimum.
7.6. Setpoint
The Setpoint function is a temperature supervising alarm mechanism, which can be activated.
A Setpoint entry defines a maximum supervising value for the target temperature. If the Setpoint
value is exceeded, an alarm state will be signaled by a relays contact. A zero (0.0) entry as a
Setpoint value deactivates the alarm functionality (Alarm mode off). To activate the alarm
functionality, set the Setpoint entry to a value between the lowest and the highest measurable
target temperature. Once the Setpoint is activated the relay changes state as the current
temperature passes the setpoint temperature.
7.7. Deadband
Deadband is a zone of flexibility around the Setpoint. The alarm does not go abnormal until
the temperature exceeds the Setpoint value by the number of set deadband degrees.
Thereafter, it does not go normal until the temperature is below the Setpoint by the number of
set deadband degrees. The Deadband is factory preset to ± 2° (C or F). Adjusting the
Deadband entry is accomplished through software or manual input via the control panel. For
information regarding the Endurance® sensor communication protocols, see section 0

7.8. Outputs
7.8.1. Analog Output (current loop)
Is a current loop output circuit to drive analog output lines. It can be set to 0-20mA or 4-20mA
output current range. Direct connection to a recording device (e.g., chart recorder), PLC, or
controller is possible. The total analog output circuit impedance is limited to 500Ω. A 16-Bit
DAC (Digital Analog Converter) guarantees a current loop resolution better than 0.1 per
temperature unit (°C / °F) over the total measurement range. A specific feature for the testing
or calibrating of connected equipment allows the current loop output to bet set to specific values,
under range or over range in RS485 or LAN/Ethernet operation mode. Via such functionality
you can force the circuit, operating in the 4-20mA mode, to transmit an output current less than
4mA (e.g. 2.0 or 3.0mA) or above 20mA (e.g. 21.0 or 22.0mA).
7.8.2. Relay Outputs
The relay output is used as an alarm for failsafe conditions or as a setpoint relay. Please refer
to section 11.2 Fail-Safe Operation on page 86. Relay output relate to the current target
temperature, displayed on the green 7-segment LED display. The relay output can be used to
indicate an alarm state or to control external actions. The relay functionality can either be set
to
NO (NORMALLY OPEN), NC (NORMALLY CLOSE),
PO (PERMANENTLY OPEN), PC (PERMANENTLY CLOSE)
by the control panel (user interface), an RS485 or LAN/Ethernet command in dependence of
the connected equipment. The relay PO and PC state can be used to detect wiring problems
between the Endurance® sensor and the process environment, where the relay contact signal
acts as a trigger.
7.8.3. Trigger
AVERAGE, PEAK HOLD or VALLEY HOLD can be reset by shorting the Trigger input signal to
Ground for a minimum of 10 msec. This can be done either with a momentary switch or a relay.
The Reset signal causes a new reading of the current measured temperature and restarts the
selected signal post processing function.

8.4. Video Sighting (Sighting Option V)
The Video Sighting capability is an option to display the focused target area on an external
computer monitor via LAN/Ethernet link. The video resolution and the refresh rate depends on
the system architecture (single or multidrop) and the available network bandwidth. Picture
capturing in different applications is possible.
8.5. Air/Water Cooled Housing (Cooling Option 1)
The Air/Water Cooled Housing allows the sensor to be used in ambient temperatures up to
120°C (250°F) with air-cooling, and 175°C (350°F) with water-cooling. The cooling media
should be connected using 1/8” NPT stainless steel fittings requiring 6 mm (0.24 in) inner
diameter and 8 mm (0.31 in) outer diameter for the tube.
Airf low should be 1.4 to 2.5 l/sec at 25°C (77°F). Water flow should be approximately 1.0 to
2.0 l/min (water temperature between 10 and 27°C / 50 to 80.6°F). The maximal pressure limit
is 5 bar (73 PSI). It is not recommended to use chilled water below 10°C (50°F).
The Air/Water Cooled Housing is equipped with plugs only removable with
a 5 mm hex wrench. Check your supplier for appropriate fittings.

For ambient temperatures exceeding 175°C (350°F), the ThermoJacket can
be used. This accessory allows operation at ambient temperatures up to
315°C (600°F)!
8.5.1. Avoidance of Condensation
If environmental conditions makes water cooling necessary, it is strictly recommended to
check whether condensation will be a real problem or not. Water-cooling also causes a
cooling of the air in the inner part of the sensor, thereby decreasing the capability of the air to
hold water. The relative humidity increases and can reach 100% very quickly. In case of a
further cooling, the surplus water vapor will condense out as water. The water will condense
on the lenses and the electronics resulting in possible damage to the sensor. Condensation
can even happen on an IP65 sealed housing.
There is no warranty repair possible in case of condensation within the
housing!

Temperatures higher than 60°C (140°F) for the E2RL sensor
model or 65°C (149°F) for the other model variants are not
recommended due to the temperature limitation of the sensor.
The use of lower temperatures is at your own risk!
8.6. PROFINET IO (Communication Option 1)
The PROFINET IO interface (Communication Option 1) is an addendum to the already
incorporated LAN/Ethernet communication (Standard Communication Option 0). Endurance®
PROFINET IO takes place over the existing LAN/Ethernet communication hardware, see
chapter 3.2 Electrical Specifications, page 8. An extra implemented software stack guarantees
the PROFINET IO communication functionality. That extra SW stack operates fully independant
of the standard LAN/Ethernet protocol stack and allows a common use of both protocols over
the same hardware.
8.6.1. Description
The Endurance® PROFINET IO module maps the object temperature, internal temperature
and the status of the pyrometer via PROFINET IO. Furthermore, PROFINET IO allows you to
change a subset of sensor parameters in data exchange mode. In the initialization phase, the
Endurance® PROFINET determines the physical structure of the node and creates a local
process image with pyrometer.

The diagnostics concept based on channel specific diagnostic messages, which are mapped
to the respective alarms. Coding standard is according to IEC 61158 PROFINET IO.
The Endurance® PROFINET IO module characteristics are:
 Conformance class: A
 Real-Time class: 1 (RT) and the Real-Time class UDP
 Connection: 1 x M12
 Transfer speed of up to 100Mbit/s full-duplex, also with autonegotiation
 I/O update cycle time from 1 ms.
 Configurable substitute value behavior in the event of error/failure
8.6.2. I/O Device Configuration
The Endurance® PROFINET takes over the task of the I/O device in PROFINET IO. Selecting
the I/O module for the process data exchange and defining the time pattern happens during
the I/O controller configuration. The configuration and parameter setting of the Endurance®
PROFINET based upon the device’s GSD (Generic Station Description) file.
8.6.2.1. GSD File
Under PROFINET IO, the device manufacturer describes the device features in a GSD file,
which is XML (Extensible Markup Language) coded and supplied to the end-user.
The Endurance® PROFINET device GSD file is:
GSDML-V2.25-FlukeProcessInstruments-Endurance-20160616.xml
8.6.2.2. Configuration
The Endurance® PROFINET IO device configuration is in accordance with the physical
arrangement of the node (slot oriented).
Module slot 0 contains the Endurance® PROFINET in its function as station substitute. It
does not deliver process data itself, but provides the parameters required to perform
communication settings of the I/O device (e.g. update cycle time).
Slot 1 (Input/Output module) reflects the physical arrangement of the pyrometer, that deliver a
part of the process and diagnostics data. All specific information on the relevant module is
contained in the associated GSD file.
8.6.3. Parameter Setting
The parameter setting of a connected pyrometer happens via “record data” sets. The I/O
module allows diagnostics message to be locked or released. Once all parameter settings are
performed, the I/O device signals that it is ready to send cyclic productive data.
8.6.3.1. Pyrometer parameters
Certain pyrometer characteristics are parameterizable during the configuration. The
parameters of the pyrometer substitute are used to set the overall settings of the PROFINET
I/O node. Some of the setting are used in the module as default settings and can be optionally
overwritten within the module configuration.

8.6.5. Diagnostics
The diagnostics information of the fieldbus communicator can be read out acyclically using
standard diagnostics data sets defined in the PROFINET IO specification.
Errors occurring when configuring and setting the parameters of the fieldbus communicator
and the connected pyrometer modules as well as external errors are reported by the
communicator via channel specific diagnostic.
In productive data exchange between the I/O controller and the fieldbus Endurance®
PROFINET IO, one byte IOPS process data qualifiers are available for each module providing
information of the validity of the pyrometer module data (good/ bad). In the event of an error
occurs during operation, the problem-indicator in APDU-Status is set by the communicator
and a diagnostic alarm is additionally transmitted.

8.7. ISO Calibration Certificate, based on DAkkS (German accreditation body)
A device specific Endurance® calibration certificate is orderable and is assigned to the
individual Endurance® pyrometer. The calibration certificate shows in a detailed list the
device accuracy as deviation values regarding the measurement normal under defined
environmental conditions. In dependence of the Endurance® device operation (e.g. smooth,
harsh environment), a periodic re-calibration needs to be taken into account, to guarantee the
measurement stability and accuracy. The calibration is traceable to the International System
of Units (SI) through National Metrological Institutes, such as NIST.
Each calibration task (first and subsequent) have to be ordered as separate line items.

10. Programming Guide
This section explains the sensor’s communication protocol to be used when writing custom
programs for your applications or when communicating with your sensor with a terminal
program over RS485 or LAN/Ethernet interface.
10.1.
Remote versus Manual Considerations
Since the sensor includes a local user interface, the possibility exists for a person to make
manual changes to parameter settings. To resolve conflicts between inputs to the sensor, the
following rules are valid:

Command precedence: the most recent parameter change is valid, whether originating
from manual or remote.

If a manual parameter change is made, the sensor will transmit a “notification” string to
the host. (Notification strings are suppressed in multidrop mode.)

A manual lockout command is available in the protocols set so the host can render the
user interface “display only,” if desired.
All parameters set via the Control Panel (user interface), the RS485 (2-wire, half duplex) or
the LAN/Ethernet interface are retained in the sensor’s nonvolatile memory.
When a unit is placed in multidrop mode its manual user interface is
automatically locked! It can be unlocked with the command XXXJ=U <CR>,
where XXX is the multidrop address.
10.2.
Command Structure
Protocols are the set of commands that define all possible communications with the sensor.
The commands are described in the following sections along with their associated ASCII
command characters and related message format information. Types of commands include
the following:
1. A request for the current value of a parameter
2. A change in the setting of a parameter
3. Defining the information contents of a string (either continuously output or periodically
polled at the option of the user)
The sensor will respond to every command with either an “acknowledge” or a “not
acknowledge” string. Acknowledge strings begin with the exclamation mark (!) and are either
a confirmation of a set command or a request of a parameter value. If the unit is in multidrop
mode the 3-digit address has to be sent out before the exclamation mark.
For a new parameter setting by the user, a range check of allowed values will be performed
by the Endurance® firmware. If an out of range for a parameter is detected by the firmware, a
Range Error is indicated and transmitted back by the Endurance® sensor.
All commands via RS485 or LAN/Ethernet interface have to be entered in
upper case (capital) letters.

After transmitting one command via RS485 or LAN/Ethernet link, the sender has to wait for
the response from the Endurance® device before sending a subsequent one. The response
time from the Endurance® device back to the sender depends on the following factors:

Operation mode of the Endurance® sensor (single or multidrop), without or with leading
device address bytes in the response string

Chosen transmission link (RS485 or LAN/Ethernet) with different transmission speed
o
RS485: 1200 bps – 115.200 bps (~ 120 char/sec – 11.520 char/sec)
o
LAN/Ethernet: max. 100 Mbit/sec (~ 10.000.000 char/sec)
An asterisk * will be transmitted back to the sender in the event of an “illegal” instruction. An
illegal instruction is considered to be one of the following:

An “out-of-range” parameter value

Any not defined command character or value entered in the incorrect format (syntax
error)

Lower case character(s) entered (all characters must be upper case)
10.3.
Transfer Modes
The protocol allows the use of two different modes: the Poll Mode and the Burst Mode
10.3.1. Poll Mode
The current value of any individual parameter can be requested by the host. The unit
responds once with the value at the selected baud rate. Additionally, the user-defined output
string can be polled.
10.3.2. Burst Mode
The Endurance® sensor transmits the user-defined output string continuously via RS485 (at
selected baud rate) or LAN/Ethernet (max. 100Mbps) in a user defined burst interval time. A
user defined burst string may contain several parameters in the user defined order.
The string may contain the following parameters:

Fail-Safe Operation
The Fail-Safe system is designed to alert the operator and provide a safe output in case of
any system failure. Basically, it is designed to shut down the process in the event of a set-up
error, system error, or a failure in the sensor electronics.
Warning
The Fail-Safe circuit should never be relied on exclusively to protect
critical heating processes. Other safety devices should also be used to
supplement this function!
11.2.1. Fail-Safe Error Codes (displayed or transmitted via electrical interface)
When an error or failure does occur, the temperature display indicates the possible failure
area, and the output circuits automatically adjust to their lowest or highest preset level. The
following table shows the values displayed on the 7-segment temperature display and
transmitted over the RS485 or LAN / Ethernet interface.

11.2.2. Analog Output current values in dependence of Fail-Safe Error Codes
The relay is controlled by the temperature selected on the display. If any failsafe code
appears on the display, the relay changes to the “abnormal” state. The exception is the “dirty
window” condition. This causes the relay to change state, leaving a normal numerical
temperature output.

If two or more errors occur simultaneously, the error with the highest priority overrules the
lower priority errors. The highest priority error will be displayed on the 7-segment temperature
display and the assigned analog output (current) value (see Table 14) will be set. For
instance, in 2-color mode, if the internal ambient temperature is over the limit and the
attenuation is to high too, the unit outputs EIHH to the temperature display and sets an analog
output current of 21 mA on the analog current loop output lines. However, since 2-color wide
band and narrow band temperatures may all be presented simultaneously through RS485 or
LAN / Ethernet interface, their over and under range conditions are independent.

Cleaning the Lens
Keep the lens clean at all times. Any foreign matter (dust, fingerprints…) on the lens or
window surface will affect 1-color measurement accuracy and may affect 2-color accuracy
too. However, care should be taken when cleaning the lens.
To clean the window, do the following:
1. Lightly blow off loose particles with “canned” air (used for cleaning computer
equipment) or a small squeeze bellows (used for cleaning camera lenses).
2. Gently brush off any remaining particles with a soft camel hairbrush or a soft lens
tissue (available from camera supply stores).
3. Clean remaining “dirt” using a cotton swab or soft lens tissue dampened in distilled
water. Do not scratch the surface.
For fingerprints or other grease, use any of the following:
 Denatured alcohol
 Ethanol
Apply one of the above to the lens. Wipe gently with a soft, clean cloth until you see colors on
the surface, then allow to air dry. Do not wipe the surface dry, this may scratch the surface.
If silicones (used in hand creams) get on the window, gently wipe the surface with Hexane.

Changing the Window
Sometimes extremely harsh environments can cause damage to the window.
A replacement protective front window (E-PW) is available.
To replace the sensor’s protective front window, complete the following:
1. With a very small flat-bladed screw driver (e.g., a jeweler’s screwdriver), pry out the
rubberized Buna-N 70 durometer O-ring. The O-ring is set in a groove in front of the
window.
2. Turn the sensor face down (window pointing down), and the window should fall out.
3. Turn the sensor face up and insert the new window. (Make sure both sides of the
window are clean.)
4. Replace the O-ring.
Warning
If you use a fine-bladed knife to remove the O-ring, be careful not to cut or
sever the ring.
Warning
Do not use any ammonia or any cleaners containing ammonia to clean the
lens. This may result in permanent damage to the lens’ surface!

Determination of Slope (for 2 – color operation)
The following slope settings are approximate and will vary depending on the metal alloy and
surface finish, as well as the application. These are supplied here as examples.
Set the slope to approximately 1.000 for measuring the following metals with oxidized
surfaces:
• Stainless Steel • Cobalt
• Steel
• Iron
• Nickel
Set the slope to approximately 1.060 for measuring the following metals with smooth, clean,
unoxidized surfaces:
• Iron
• Nickel
• Tantalum
• Stainless Steel • Rhodium
• Tungsten
• Cobalt
• Steel
• Molybdenum
• Platinum
Molten iron also has an approximate slope setting of 1.060.
How to determine slope?
The most effective way to determine and adjust the slope is to take the temperature of the
material using a probe sensor such as an RTD, thermocouple, or other suitable method. Once
you determine the actual temperature, adjust the slope setting until the sensor’s temperature
reads the same as the actual temperature reading. This is the correct slope for the measured
material.

Percentage of allowed signal reduction
Figure 84 and Figure 85 show each sensor model’s percentage of allowed signal reduction at
all temperatures. Refer to these graphs to estimate what percentage of target area must be
visible to the sensor at temperatures below the minimum temperature (95% attenuation) as
shown in this manual.
1-color sensors see polluted atmosphere and dirty windows and lenses as
a reduction in energy and give much lower than actual temperature
readings!

Determination of Emissivity (for 1-color operation)
Emissivity is a measure of an object’s ability to absorb and emit infrared energy. It can have a
value between 0 and 1.0. For example a mirror has an emissivity of 0.1, while the so-called
“Blackbody“ reaches an emissivity value of 1.0. If a higher than actual emissivity value is set,
the output will read low, provided the target temperature is above its ambient temperature.
For example, if you have set 0.95 and the actual emissivity is 0.9, the temperature reading will
be lower than the true temperature.
An object’s emissivity can be determined by one of the following methods:
1. Determine the actual temperature of the material using an RTD (PT100), a
thermocouple, or any other suitable method. Next, measure the object’s temperature
and adjust emissivity setting until the correct temperature value is reached. This is the
correct emissivity for the measured material.
2. If possible, apply flat black paint to a portion of the surface of the object. The
emissivity of the paint must be above 0.98. Next, measure the temperature of the
painted area using an emissivity setting of 0.98. Finally, measure the temperature of
an adjacent area on the object and adjust the emissivity until the same temperature is
reached. This is the correct emissivity for the measured material.
