2.2 Modline 5 Description

The IRCON Modline 5 is an Infrared Thermometer Sensor. State of the art digital circuitry and firmware provide excellent measurement accuracy, repeatability and overall performance. New diagnostics check the status of the Sensor (such as detector temperature, sensor failure) and some of its external environment (such as analog current output open circuit condition and case temperature). An internal function check is performed without the need to block the lens. The check tests for and internal circuit and detector operation. Alarms and Error Codes are outputted when out of limit conditions are sensed.
The Patented Dirty Window Detector option checks the Sensors front window for loss of signal because a buildup of contaminants.
An easy to read, bright LED alphanumeric temperature display and three pushbuttons on a keyboard is located at the rear of the Sensor. Each Sensor has a full complement of easy to navigate rear panel setup and operating functions. Operation as a standalone Sensor is accomplished simply by using its rear panel keyboard to access and setup operating parameters. The Sensor can display and output temperature signals, and operates with an external dc power source.
The Sensor optics and electronics are contained in a small, rugged stainless steel NEMA 4 (IP65) rated housing. Modline 5 accessories for mounting, air purging and cooling the Sensor have been designed to maintain a small installation footprint.

3 Sensor Installation

3.1 Mechanical Installation

This section provides instructions for installing the Modline 5 Sensor. Sighting, aiming, focusing and resolving targets are explained. Mounting and protection of the Sensor in hot and dirty environments using installation, air purging and water cooling accessories are presented.

3.2 Sensors

Figure 2: Standard Sensor Figure 3: Sensor with Dirty Window Detector
Two Sensors types are available in the Modline 5 Series, standard Sensor or Sensor with the Dirty Window Detector option. The front of the standard Sensor consists of a front objective lens only. The Sensor with the Dirty Window Detector option has internal components and an external protection window located in front of the objective lens. A hooded mirror extends out in front of protection window. The sensors are illustrated in the photographs above and below.
The Patented Dirty Window Detector option, IRCON, inc. Patent Number 5812270, checks the Sensors front window for loss of signal caused by a buildup of contaminants. A Coarse or Sensitive level of signal loss can be selected. Visual Alarms and a relay output are provided to indicate window contamination.
Dimensions for the Sensor with the DWD are slightly different because of the additional components. Measurement of the optical working distance on the standard Sensor is made from the front surface of the unit. The working distance determination on the Sensor with DWD requires a simple calculation. Measurement is made from the front tip of the hooded mirror and 66 mm (2.6 inches) is added to the distance to compensate for the extended optics.

3.2.1 Sensor Parts

The photograph below illustrates the Sensor parts called out in this manual.
Figure 5: Sensor Parts
The EP – 5 Protective / Visual Sight Window with a dimming filter is available for viewing very high temperatures. This replaces the standard rear protection and sight window shown above.

3.3 Sighting Methods

The Modline 5 Sensor is a precision electro-optical instrument that senses infrared radiation. This signal
is processed by the unit’s digital circuits to provide an output proportional to the temperature being measured. The Sensor’s linear analog current output and RS-485 digital temperature signals are brought
out through a connector on the bottom of the Sensor with a shielded cable. The output signals are then connected to compatible devices within the process measurement system.

3.3.1 Sighting and Focusing

The Modline 5 is a variable focus instrument that features visual through-the-lens sighting by means of a viewing sight at the rear panel of the Sensor. An optional internal Laser for through-the-lens aiming is available. Focusing with either the visible or laser sight is accomplished using the rotating rear section of the Sensor.

3.3.2 Visual Sight

The Modline 5 visible sight is aimed and focused onto the target to be measured as simply as an ordinary camera. The rear focus is smooth, utilizing almost one turn of the focusing section.
A circular reticle is contained within the Sensor’s optical system and is visible when viewing through
the sight. During temperature measurement, the target image is superimposed on the reticle. Focusing is performed by adjusting the rear focusing section while viewing the scene until the target area is clear and well defined. Illustrated below is a properly focused Sensor viewing an induction heated rod. The visible sight rear panel is shown below.

Rev. L6 Feb 2017 Modline 5
Figure 6: Visible Sight Figure 7: Reticle
When properly focused, the area of the target within the reticle will be measured. The Sensor infrared detector will “see” the same image seen defined by the reticle. Approximately 97% of the measured energy will come from the area defined by the reticle.
To check or adjust focus, slowly move your head slightly from side to side or up and down. Note whether the target appears to move with respect to the reticle. If it does, adjust the lens focusing section, until there is no perceived motion between the reticle and target (hence eliminating parallax between the two). The instrument is then in sharp focus. Lock the lens rear focusing section in place using the locking thumbscrew on the bottom of the Sensor.
If looking through a sight tube or sight hole, position, align and rotate the Sensor and Sight tube to center the reticle in the field of view.
For Modline 56 sensors: occasionally, a calibration flag that operates during the Sensor Calibrate test may move into the viewing area during shipment. If this occurs, the viewing area will be dark and appear obstructed. This flag will be positioned correctly when power is applied to the Sensor.

3.3.3 Laser Sight

With the optional Laser sight, a laser light spot is projected onto the target and used to aim the Sensor. The same rear focusing method applies and is to be used to adjust for the smallest laser light spot. The projected focused laser image will be approximately the same diameter “spot” as measured by the detector. See Section 3.4 Sensor Optical Characteristics, page 26 for determining spot size.
The Laser image is reflected from the target surface. The image can easily be seen on most targets at distances of 10 feet and further. The visibility of the reflected image is dependent on the reflection characteristics of the target material as well as the intensity of the ambient lighting. When viewing hot glowing targets, the visibility of the image also depends upon its temperature. The color and intensity of a hot glowing object may override the reflected Laser image.
Use of the laser on distant targets or poorly reflecting targets may require some white paint on the target or a white substitute target such as a sheet of paper to accomplish focusing. Ambient light dimming may be required for targets that reflect poorly. For difficult conditions, pre-focus the Sensor optics while aiming the laser at a white reflective target. Then use the Laser to aim the pre-focused Sensor on to the target.

3.4 Sensor Optical Characteristics

3.4.1 Optical Resolution

The Sensing Head is sensitive to infrared radiation in the area indicated by the Cone of Vision in the illustration below.
Figure 11: Cone of Vision and Spot Size Formula
The diameter of the cone at any point will determine the area of measurement at that point. Any part of the target or other intervening object positioned within the cone will be imaged on the detector. Anything seen by the detector will become part of the measurement.
When the Sensor is sighted on an object, you are “aiming” or positioning the cone of vision on the object.
When you focus, you are adjusting the optical system elements so the focal point is at the surface of the object. The measurement area, as seen by the detector, will then be outlined in the reticle. The reticle only defines the measured area (spot size) in the focused condition.
The formula d = D/F defines the spot size at the focal point. Simply divide the Working Distance (D), measured from the front of the Sensor to target by the Resolution Factor (F) to determine the Spot Size (d). Resolution factors for Sensor Model and Lens combinations are provided in the table on the following page. The focusing range for each lens type is also provided in the table. The focusing range defines the allowable range for the Working Distance.
For Sensors with the Dirty Window Detector Option, the Working Distance (D) is calculated by measuring the distance from the front tip of the protruding hood to the target and then adding 2.6 inches (66 mm).

3.4.2 Lens Focusing Ranges and Optical Resolution Factor

The table below lists Lens Type and Focusing Ranges for the Modline 5 Series 52, 56, 5G and 5R. Two ranges are shown. The first range is for a Sensor without the Dirty Window Detector Option (DWD) option. The distance is measured from the front metal surface of the standard Sensor.
d = D / F
where:
d = diameter of cone at focal point
D = distance from front of Sensor to focal point.
For Sensors with DWD Option, add 2.6 inches (66 mm) for distances measured from tip of front hood.
F = Resolution Factor of Sensor Model and Lens combination

The second range is for a Sensor with the DWD option. This distance is measured from the tip of the front mirror hood. Very close lens types that include alpha character C are not useable with the DWD option.
Some installation, cooling and air purging accessories will limit some of the usable close focus range accessory.
The Model number and installed lens type is found on the Sensor Model number tag. Range tolerance of is ±10%.

3.4.3 Table of Model and Lens Type Combinations with Focusing Ranges

The Optical Resolution Factor for each Model and Lens combination is given in the table. Use the formula: d = D / F to calculate the spot size at any working distance within the specified range. The smallest spot size can be determined using the closest distance within the range.

3.5 Measuring Temperature with Brightness and Ratio Sensors

3.5.1 Resolving Targets with Brightness Sensors

When using single color Series 52, 56 and 5G brightness Sensors, best results are obtained when the resolved portion of the target is two times the diameter of the reticle.
The Sensor measures the average temperature of the target or object seen in the reticle. Targets smaller than the reticle will result in low temperature readings if the background (object within the cone of vision beyond the target) is lower that the target temperature. If the background temperature is higher than the target, the averaged temperature indication will be higher.
Low temperature indications can also be caused by other factors. An out of focus cool object cutting the cone of vision anywhere between the target and Sensor, or a small target may shift position and move partially out of the measurement cone.

3.5.2 Obstructions in Cone of Vision

Errors can be caused by objects positioned between the Sensor and target. Evaluate the Sensor’s “Cone of Vision” and if there is any possibility that an intervening object is within the cone, select a different
viewing position. An object inside the Cone of Vision will be visible to the detector and may cause an error in the temperature measurement. Obstructions in the cone of vision, whose temperatures are lower than the target temperature, will generally cause lower temperature readings when using single color brightness units. The obstruction may not be seen clearly in the instrument sight if it is some distance away from the target and out of focus. Such an obstruction is illustrated below.
High temperatures can be caused by an out of focus hot object cutting the cone of vision anywhere between the target and Sensor.
Two color ratio units are usually not affected by obstructions that are significantly lower in temperature than the target. Ratio units are affected by hot objects in the cone of vision that are much higher in temperature than the target. If too high, the hot targets can dominate the measurement. If the object temperature is the same, the measured temperature is not affected.
Figure 13: Cone of Vision Obstruction

3.5.3 Resolving Targets with Two Color Ratio Sensors

Modline 5 Series 5R Ratio Sensors utilize a dual detector assembly that measures temperature by comparing infrared radiation levels in two wavelength bands (0.85 to 1.05 microns and 1.0 to 1.1 microns). Temperature readings are based on the ratio of the two signals in these bands.
Obstruction
Target Cone of Vision
Sensor Installation
30
Rev. L6 Feb 2017 Modline 5
Because Series 5R Sensors measure the ratio of radiation intensities at two wavelengths rather than the absolute intensity of radiation at a single wavelength, they are almost immune to error caused by loss of signal. Small targets that do not fill the field of view and partial obstructions from bursts of steam, dust and solid objects in their sight path can be tolerated.

3.5.4 Signal Reduction

Three causes contribute to the loss of signal:
 Low target emissivity.
 The measured object is too small to fill the reticle as seen in the Sensor sight and is not completely
resolve.
 Partial obstruction of the optical path caused by smoke, steam, dust, dirty window or a solid
object.
The total reduction in signal is the sum of the losses from all three causes.
Example: Assume the target emissivity is 0.45. The reduction in signal due to low emissivity is 55%. If the instrument can operate with a 95% signal reduction, another 40% can be lost due to an unresolved target and/or obstructions in the cone of vision such as smoke, steam, dust, a dirty window or partial blockage by solid objects.
Figure 14: Invalid Measurement Conditions
When you reach the maximum allowed reduction, the Sensor will indicate “Invalid”. An Invalid
measurement condition also occurs, without any obstructions, if the target temperature signal is below a level that can be accurately measured by the instrument.
Signal Reduction Tolerated
The Series 5R Sensors have a limit as to how much the signal from a hot target can be reduced. The reduction in the signal can be as high as 95% with target temperatures above 800C (1500F). The
Target Emissivity = 0.45

amount of signal reduction that the Series 5R Sensors will tolerate depends upon the Sensor temperature range and the target temperature. The signal reduction tolerated is less in the bottom portion of the range. The Sensor will indicate invalid when the measurement is not possible.

3.5.5 Summary

The spot size and target size relationship is not as critical for Series 5R Sensors which use the two color ratio method. Avoid emitted radiation from objects in the same field of view (cone of vision) either in the foreground or behind the target that are at temperatures hotter than the target. Reflected or emitted radiation from these interferences can cause measurement errors. Significantly cooler objects, well below the target temperature, will not cause measurable errors.
For best results, brightness sensors that measure radiation intensity at a single wavelength should be installed so the target area is larger than the instrument spot size. If possible, adhere to the target size is twice the spot size rule for all types of instruments.

3.6 Sensor Installation Planning

Mechanical Installation of the Modline 5 Sensor requires determining sighting and focusing requirements, locations for installing Sensors, accessories and cable routing. Planning also includes evaluating environmental conditions that may cause contamination of the Sensor optics or overheating of the Sensor or other Modline 5 components. Re-location of the installation or air purging and water cooling accessories may be required to overcome adverse conditions.
Pre-focusing the Sensor’s optical system may be necessary if the Sensor is to be mounted in a difficult location and not accessible. Pre-focus by setting up a well-defined target such as a printed page at the exact distance of the target, and then lock the rear focusing section.
Setup of the Sensor parameters can also be pre-determined and set before installation.
The following guidelines will help you in planning the Sensor installation.
Mechanical Mounting Location Requirements
The Sensor is installed using the mounting brackets and flanges, air purging and water cooling accessories illustrated in the Section 3.9 Modline 5 Mounting, Cooling and Air Purging Accessories, page 35.
Sensor Mounted to Earth Ground Potential
If the proposed mounting surface is at Earth Ground potential, you can mount the housing directly to this surface. If the surface is not at Earth Ground potential, electrical insulating material and non­conducting hardware must be used to isolate the Sensors.
Sensor Interconnecting Cable Length
Maximum cable length between the Sensor and the POI Power Supply/Signal Interface Box or Terminal Plate is 350 ft. (107 m). Maximum temperature rating of the Sensor Interconnecting cable is 200 °C (392 °F). Plan the cable route accordingly.
Ambient Temperature Limits for Sensor, POI Box and Terminal Strip Plate
The ambient temperature at the mounting locations for the Sensor, POI Power Supply/Signal Termination Box and The Terminal Strip Plate must be between 0 and 55°C (32 and 130°F).
If the ambient temperature at the mounting location is beyond these limits, precautions must be taken to protect the Sensor. A WJA Water and Air Cooling Jacket are available for protection against excessive temperatures. Use of insulation and reflective shielding for additional protection from
Sensor Installation

Rev. L6 Feb 2017 Modline 5
extreme ambient temperatures and radiated heat are described in Section 8 Applications Guide, page
129.
The POI Power Supply/Signal Termination Box and The Terminal Strip Plate must be re-located to a location that the ambient temperature is between 0 and 55°C (32 and 130°F).
Lens Protection
Be sure the lens is protected from contamination and is accessible for maintenance. If dust, oil, vapors, etc. collect on the lens, low temperature indications will result. Use an APA – Air Purge Accessory to maintain a clean lens. Consider use of a Sensor with the Dirty window if errors caused by lens contamination can seriously affect the process.
Focal Limits
To permit focusing, the target distance must be within the focal range of the objective lens. Ranges for the Modline 5 objective lenses are given in Section 3.4 Sensor Optical Characteristics, page 26. Range limitations for close focus lenses may be encountered with the use of certain mechanical accessories.
Use of Windows
If it is necessary to view the object through a window, as is the case when the object is being heated in a vacuum or inert atmosphere, correctly select the window material. The material must have constant transmission characteristics in the operating wavelength range of the Sensor type being installed. Information on windows is provided in Section 8 Applications Guide, page 129 of this manual.
Reflections
Reflections from radiating objects represent a potential source of error in temperature measurement. The total radiation seen by the Sensor will be a combination of intrinsic, emitted, radiation plus reflected radiation from a nearby hot object off the target surface. Examples of interfering sources are hot furnace walls and heating elements that are hotter than or nearly as hot as the target object.
Most reflection problems can be eliminated by changing the viewing angle or shielding the reflections. Suggestions for anticipating and eliminating common reflection problems are provided in Section 8 Applications Guide, page 129.
Indirect Viewing
In some situations, it may be necessary to view the target indirectly by means of a mirror. The characteristics of the mirror and the positioning of both the Sensor and mirror are critical in this type of arrangement. Refer to Section 8 Applications Guide, page 129 for more information.
Viewing Angle
Viewing angles are limited in some situations. Guidelines are provided in Section 8 Applications
Guide, page 129.

3.13 Sensor Installation Checklist

To ensure accurate, reliable, and trouble-free operation, check the installation for the following:
Sensor is properly mounted and aligned with no obstructions in optical path.
Sensor lens is focused on target. If possible, target size is at least twice diameter of reticle size as seen in the viewing sight (i.e. twice the calculated spot size at the viewing distance).
Rear Protective window has been securely installed on back of Sensor. After completing the sighting and focusing routines, screw the protection window back onto the Sensor to maintain the NEMA 4 (IP65) environmental rating.
Sensor lens is protected by air purge and clean purge air if atmosphere is dirty, oily or corrosive. Do not use purge air with oil or water. Use instrument air or filter adequately.
Sensors with the Dirty Window Detector Option require an APA air purge or other protection as explained in Section 3.8 DWD Installation Requirements, page 34. If the purging air quality is poor, use an efficient filter. In worst cases, leave the air purge assembled to the Sensor, but disconnect the air supply.
Sensor is adequately protected by water or air cooling and/or additional insulation if ambient temperature exceeds safe limits.
Sensor is not subjected to direct or reflected radiated heat from oven walls, flames, etc. that cause it to

Consider the cable route. The cable should be protected from plant traffic and any hostile environments. Avoid high temperature zones or areas subject to electrical or high frequency interference.

4.4 TSP Terminal Strip Plate

The TSP is required when the POI Power Supply/Signal Interface Box is not used. This plate mounted terminal strip with terminal identification label and suppression components allows use of the Modline 5 Sensor and Cable with user-supplied enclosures and power supplies. The TSP ensures Sensor and cable operation meets RF emission and immunity standards required for CE certification.
The 24Vdc Sensor Power Supply should be limited to 2 Amps.
An earth ground wire is to be connected to the ground stud at the bottom of the Terminal Plate. Minimum size wire is 18 AWG (1 mm²). A crimp terminal is supplied to mount on the stud.

4.4.1 Dimensions and Installation

The Terminal Plate must be installed in a suitable user-supplied grounded enclosure for protection from electrostatic discharge (ESD).
Four 0.196 inch (5mm) diameter holes are used to mount the plate. See photo below for mounting dimensions.
The approximate overall rectangular plate dimensions are 5.39 inches (136.9 mm) long by 3.42 inches (86.9 mm) wide and 0.8 inches (20.3 mm) high.
Plan access for cables and working space. Minimum Sensor interconnecting cable bend is 3 inches (76 mm).

4.5 Sensor Interconnecting Cable Preparation

4.5.1 Cable Preparation

It is very important that the cable shield be properly prepared and installed. If the Terminal Strip Plate is used, the shielding must be clamped to the ground shield clamps on the plate.
All cables must be properly dressed for shield grounding. Twisted pair wires must remain twisted and kept as short as possible. The IRCON Sensor cable is supplied with the connector attached on one end. The opposite wiring end is prepared and supplied as per the following procedure. If the cable is shortened, the preparation procedure must be followed. User supplied cables require similar preparation.
A. Strip off 10 in. (254 mm) of the outer jacket.
B. Partially cut back the outer braided shield. Leave 1 inch (26 mm) of shield exposed to attach a
strain relief or connection to a Terminal Strip Plate shield clamp.
C. Keeping wire pairs twisted, cut wires to lengths shown in the following table. Strip all wire pairs
ends 3/8 inch (10 mm) and tin with solder.

4.6 Terminal Strip Plate – Sensor Interconnecting Cable Installation

Clamp the cable shield to the shield clamp on the left side of the Terminal Strip Plate.
Insert the 9.5 inches (241.3 mm) long Red and Red/White twisted pair through the ceramic ferrite core supplied with the plate. Keep the exposed wire length between the shielded cable end and the ferrite core as short possible. Maintain enough length to allow the core to be inserted into its mounting clip.
Bring the Red and Red/White pair around the outside of the core as tight and as close to the core surface as possible. Repeat until 2 wraps have been completed as shown. Cut the pair to the required length for connection to the terminal strip. Strip wire 3/8 inch (10 mm) and tin with solder.
Route all twisted wire pairs to their corresponding terminals identified by wire color. Insert the tinned wire ends of each color coded wire into its terminal and tighten.
The 100 Ohm 1 watt fusible resistor placed from the ground stud to power supply common is not shown in these illustrations.
Figure 59
Figure 60

4.7 Connecting Device Cables to Terminal Strip Plate

4.7.1 Recommended Cable Types

To maintain signal integrity and reduce noise pick-up, twisted pair shielded cables with overall foil and braid shielding should be used for connecting to all Sensor inputs and outputs. Belden low capacitance computer cable types 9829, 9830, 9831, 9832, 9839 and 9833, or equivalent cables are recommended. Each of these cables has a different number of wire pairs varying in quantity from 2 to 7 pairs.
The cable selected should have a twisted pair nominal impedance of 100 ohms and nominal capacitance between conductors should not exceed 15.5 pF/ft. (50.9 pF/m).
Prepare the cables as explained in Section 4.5 Sensor Interconnecting Cable Preparation, page 66. Ground cable shields on the Terminal Strip Plate by inserting the prepared braid under the shield clamps.

measured temperature. The corresponding temperature span is adjustable. Temperature signal connections are made to the Analog Output + and Analog Out – terminals.
Single or multiple series connected indicators, recorders or other instruments can be connected. The total current loop series DC resistance of all devices and wiring should not exceed 600 ohms.
Figure 62
The minus side of the Analog Output is connected to power supply common (see section 4.11 System
Grounding and Shielding, page 79). Use instruments with ungrounded differential inputs. If
instruments with grounded inputs are connected in the loop, the output may be inoperable or inaccurate.
If the Analog output is not used, insert a jumper wire or 100 Ohm to 500 Ohm value resistor across the output terminals. This will prevent an Analog Loop malfunction Alarm (Error X108) from occurring.

4.7.6 Converting the Analog Output from a mA output to a 10 Volt Output

To convert the Analog mA output to 0 to 10 Vdc Output, place a 500 Ohm resistor across the output terminals. The Sensor Analog output (SOUT) should be set to 0 to 20mA range.
The minus side of the Analog Output is connected to earth ground. Use instruments with ungrounded differential inputs. If instruments with grounded inputs are connected, the output may be inoperable or inaccurate.
Figure 63

4.7.7 Current Input for Remote Emissivity, E-Slope or Laser Operation

You may make remote adjustments of the Emissivity or E-Slope by sending a scaled analog input of 4 to 20 mAdc. The Modline 5 senses an input and overrides any Sensor rear panel or RS-485 settings of Emissivity, E-Slope or Match.

Example for Emissivity: A 4 mAdc signal corresponds to an emissivity setting of 0.100. A 20 mAdc corresponds to an emissivity of 1.000. The relationship for the values in between is linear.
Example for E-Slope: For the E-Slope settings, the 4 to 20 mAdc signals correspond to settings of 0.800 to 1.200. The relationship for the values in between is linear.
Connections are made to Terminals mA In + and mA In –. Input impedance is 120 Ohms. Use Shielded cable at the TSP Terminal Strip Plate ground terminal.
The (–) terminal of the mA input current input is isolated, but will only tolerate a difference of approximately 2 Volts between it and Sensor Common.
Remote Laser Operation is selected in COMMS – LASR Menu. See manual Sections 5.8 and 5.11 for selecting and operating this function. To configure and wire for remote I IN current/switch Laser operation follow the instructions given below. When selected for remote Laser Operation, Emissivity and E-Slope are not changed by the input current.

4.7.8 Current Input Terminal Connections for Remote Laser

Use a DC power supply with a maximum output of 24 volts. Maximum input current allowed is 20 mA. Overloading the input can cause a Sensor Fail alarm.
When calculating a series resistor value to use with a supply voltage, subtract the 120 ohm Sensor internal circuit impedance from the calculated value. See Table below. On threshold is 15 mA.
DC Voltage Supply
Resistor Value
10 Volts
560 ohms (Plus 120 Internal = 680 ohms total) for 15 mA
24 Volts (Can be Sensor Supply)
1500 Ohms (Plus 120 Internal = 1620 ohms total) for 15 mA
Table 16
Connect the supply circuit as shown in the wiring diagram. The I IN – terminal can be connected to a floating or earth grounded power supply terminal. In either case, it must be connected directly to the power supply.

4.7.9 Peak/Hold Switch for Remote Peak Picker Reset, Track and Hold or Laser
Operation.
An external switch connected to the Pk/Hd Switch terminals will control signal conditioning of the Modline 5. These terminals can also be used for remote Laser activation.
Switch action for the Peak Picker will provide the following control. Momentary closure of the switch (>0.08 second) immediately resets the Peak Picker. If the switch is continuously closed, the Temperature Display will show direct readings without any Peak Picker signal conditioning. The switch may be manually operated or it may be a contact on a timer, relay, or any other process operated switch.
Switch action for Track and Hold will provide the following control. With the switch open, temperature tracking continues (Track). With the switch closed, the displayed temperature will be held at the last reading (Hold). The switch may be manually operated or it may be a contact on a timer, relay, or any other process-operated switch.
Remote Laser Operation is selected in COMMS – LASR Menu. See manual Sections 5.8 COMM – Setup
of RS-485 Digital Communication Configuration, page 95 and 5.11 Laser Sighting Operation, page 102
for selecting and operating the remote laser function. The PkHd terminals are dedicated to Laser operation when selected. To wire for remote PkHd switch operation follow the diagram given below.

4.7.10 Sensor Alarm Relay Contacts

The sensor tests its case temperature, detector assembly temperature, output current flow, etc. The Check function checks internal circuit and detector operation. The optional Dirty Window Detector measures the Sensor’s window condition. One or more out of limit conditions sensed by these tests triggers an Alarm and operates the Alarm relay within the Modline 5. The relay contacts may be used in the process control system to indicate measurement conditions do not allow process temperature measurements or Sensor operation may be impaired. Appropriate action for the various conditions can then be initiated.
Alarm Relay contact connections are made to the Alarm Relay Terminals. The relay contact is rated for 24 Volts AC or DC, 1 AMP resistive loads only.
The Alarm relay can be configured for Normally Open or Normally Closed operation. The configuration can be performed at the Sensor Rear panel with the Engineering RELY function, or with RS-485 digital communications.
Set the relay operation to correspond to proper and safe use of the contacts in your overall measurement system.
Select N C. for closed relay operation with Sensor not in Alarm condition (open in alarm state).

4.8 Selection of a Power Supply for Sensors used with TSP Terminal
Strip Plates
When using a Modline 5 Sensor with the TSP Terminal Strip Plate, select a switching type power supply that will provide reliable startup. The power supply output should remain at rated voltage during the Sensor current loading that occurs at startup. Sensor displays and alarms will not properly start with low voltage.
A dedicated Power supply for each Sensor is the simplest and best configuration. Section 4.9 RS-485
Multi-Drop Network Power Supply and System Wiring, page 75, provides instructions for using a
chassis mount 15 watt, 24 Volt DC Switching Power Supply supplied by IRCON. The part number for this power supply is 551632.
Multiple Sensor installations may require more than one power supply. A single supply will not be able to properly provide startup power to a large number of sensors. Limit the number of Sensors supplied from a single power supply to no more than 2 or possibly 3. Dividing the Sensors into groups can
Sensor Wiring
74
Rev. L6 Feb 2017 Modline 5
eliminate long cable runs when sensors are installed at distant locations. This is especially the case when AC power is available locally.
The standard Modline 5 cable that is routed between the Sensor and TSP Plate is limited to 350 Feet (107 meters). The power supply wires in this cable are 22 gauges. This maximum cable distance and wire gauge assures enough voltage will be available at the sensor. The voltage drop developed across the power supply wire pair will be small and not cause a low voltage condition.
Whether powering a single Sensor or multiple Sensors, there may also be significant voltage drops across the wires connecting the power supply to each TSP. Keep the wire lengths between the power supply and Terminal Strip Plate short. The voltage drops developed are dependent upon length and gauge of the wire.
A qualified electrician or technician should apply power with the all sensors connected and measure 24 VDC, +/– 5%, at the Red and Red/White power supply terminal connections on the left side of each TSP Terminal Strip Plate.
A 100 Ohm1 Watt fusible resistor is supplied with all TSP plates to connect power supply common to earth ground as shown in the diagrams.

4.8.1 TSP Terminal Strip Plate DC Power Supply Connections

These instructions are for the Terminal Strip Plate only. For the POI Box, see the separate POI manual for mounting instructions, wiring requirements, and specifications.
See Section 4.4 to review Terminal Strip Plate enclosure, power supply and ground connection requirements.
The external 24 VDC power is wired to the right side of the Terminal Strip. Use 22 AWG (0.35 mm²) wire. Total power supply cable run using 22 AWG (0.35 mm²) wire is 107 meters (350 feet). Shielded cable is recommended. Paralleling two pairs of 24 AWG (0.25 mm²) cabling is equivalent to using 22 AWG (0.35 mm²) cable.
Connect the positive side of the 24 VDC power source to the +24VDC Terminals. Connect the common or negative side of the source to the Common Terminal.

4.8.2 Power Supply Common Ground Connection

The Common side of the power source must be connected to earth Ground. If the dc power source common is not already connected to ground at some point in the system, make the connection at the Terminal Strip Plate.
The recommended and preferred method of making the ground connection to is to connect the power supply Common Terminal to Ground through a 100 Ohm 1 Watt fusible resistor. The resistor is inserted between the Ground Stud and the Common Terminal.

4.9 RS-485 Multi-Drop Network Power Supply and System Wiring

Multiple Modline 5 Sensors communicating via RS-485 with a Host device are installed in a multi-drop network configuration. The Modline 5 MSI Multiple Sensor Interface, a PC, a PLC or other Control system are Host devices. A block diagram of a multi-drop network is shown in the adjacent illustration. It is important to wire the network properly to prevent noise pickup and have reliable operation.

Rev. L6 Feb 2017 Modline 5
Sensors should be wired in tandem as shown in the diagram. The RS-485 terminals from the Sensor furthest from the host device are wired to the next closest Sensor. Then the RS-485 Terminals of that Sensor should be wired back to the next closest sensor. Do this until all sensors are wired. Do not use any other configuration.
A 120 ohm termination resistor should be placed across the RS-485 terminals of the Sensor furthest from the Host device as shown in the diagram. Consult the manual for the Host device to determine if any termination resistor is required at its terminals. The IRCON Model MSI Interface does not require a termination resistor at its input.
To maintain signal integrity and reduce noise pick-up, twisted pair shielded cables with overall foil and braid shielding should be used for connecting to all Sensor inputs and outputs. Belden low capacitance computer cable types 9829, 9830, 9831, 9832, 9839 and 9833, or equivalent cables are recommended. Each of these cables has a different number of wire pairs varying in quantity from 2 to 7 pairs.
The cable selected should have a twisted pair nominal impedance of 100 ohms and nominal capacitance between conductors should not exceed 15.5 pF/ft. (50.9 pF/m).
Select power supplies and install cables as instructed in previous sections of the manual.
Figure 68

4.9.1 Computer Communications Requirements

The Host device communicating with The Modline 5 Sensor should have an RS-485 communication port. If not, an RS-232 Port and a RS-485 to RS-232 converter can be used. An RS-485 to USB converter can also be utilized. The combined communications port and converters used must have the capability to communicate over a 2 wire, half duplex RS-485 network at speeds fast enough to handle command requests with reply turnaround times of one-millisecond or less.
The following converters will provide satisfactory performance when used with Modline 5 Sensors.

5.1 Sensor Rear Panel Setup and Operation

5.1.1 Introduction

Become familiar with the displays, pushbutton controls, menus and the functions required for Sensor setup and operation as described below. Modline® 5 instruments are thoroughly tested and calibrated to factory specifications before shipment and should require no more than brief function selections and adjustments to meet the requirements for measurement of process temperatures.

5.2 Rear Panel Keyboard, Displays and Sight and Laser Aiming

5.2.1 Description

Located on the rear of the Modline 5 Sensor are: a keyboard panel with three setup pushbuttons, three red word indicators for Setup, Alarm and Window (for the Dirty Window Detector optional feature), and a four character green alphanumeric Light Emitting Diode dot matrix display with adjacent green °F and °C indicators.
The display is identified as the Temperature (TEMP) display in this manual. The TEMP display and °F and °C indicators are used for temperature indication in Fahrenheit or Celsius. LOW or HIGH is displayed when viewing target temperatures below or above the Sensor temperature range. INV is presented on the display for Invalid ratio temperature measurement conditions. Setup parameters will be shown on the TEMP display during setup and error codes displayed in response to an Alarm inquiry.
Two of the pushbuttons are Down / Up Arrows labeled and . The third is an Enter pushbutton labeled ENT with the keyboard enter symbol . These buttons are identified as ▼▲ and in this manual.
A sight for visually aiming the Sensor is located in the center of the keyboard. The process target and Sensor circular reticle can be seen when viewing through the sight. Sensors with the Laser aiming option have a pushbutton to energize a laser in place of the sight.
Access to the keypad requires removal of a screw on protective window with O-ring gasket. The protective window must be in place during temperature measurement to maintain the NEMA 4 (IP65) Sensor housing rating.

5.5 Warm-up and Initial Setup

5.5.1 Series 5R, 5G, 52 Power On and Warm-up

When power is applied to the Sensor, a three to five second initiate condition occurs. All segments of the dot matrix TEMP display and all word and symbol indicators are lit. The alarm relay is always held open during this short period.
After application of power, a warm-up time of approximately 5 to 15 minutes is required for the Sensor’s infrared detector and/or electronics. The Sensor Rear Panel Alarm indicator will be lit and Error Code X104 (Detector Cold) displayed when the arrow is depressed. During the warm-up time, temperature
measurements can be made and outputs are operational. However, the Alarm signifies that the temperature indication may not be accurate. Temperature indications will be accurate after the Alarm
indicator has turned off when warm-up is completed. If there is a brief power outage, Sensors may restart
and go into the initiate and warm-up conditions described above.
The Sensor Check function should not be initiated until the Sensor has warmed up and the Alarm indicator has turned off. An Out of Calibration Alarm (X102) may occur if initiated during warm-up. If this Alarm
occurs, repeat the Check.

5.5.2 Series 56 Models Power On and Warm-up

Series 56 Models include a Self-Calibration feature which is performed as part of the power on routine.

5.5.3 Initial Rear Panel Display

After the warm-up period is over, you should observe one or more of the Modline 5 Sensor responses described below on the TEMP display and at the outputs. During initial setup, because the Sensor is not adjusted for the process, these initial displays are expected.
1.Target Within Range If the Sensor is viewing a temperature within its range, it will display a temperature value. Equivalent analog signals will be supplied to any devices connected to the analog outputs (e.g., recorder or remote indicator). If initial setup has not been set to match operation to the process, the displayed temperature and analog outputs will not be a true measurement of the target temperature.
2. LOW / HIGH Indication If the measured temperature is below or above the Sensor temperature range limits LOW or HIGH will be shown on the temperature display. The Alarm Indicator does not light because these are normal conditions.
3. INVALID An Invalid condition will be indicated any time the sensed infrared radiation is considered to be inadequate for two color Ratio Sensor measurement. The word INV is indicated on the TEMP display. If the Invalid Alarm (iALM) is set to On, the Alarm Relay will be in alarm condition and the word Alarm lit on the Sensor rear panel.

5.5.4 Initial Sensor Setup

Initial Sensor setup should follow the menu orders indicated in the following instructions. Menu navigation is shown using the &▲▼ symbols for Enter and Up / Down arrows. The menus and functions available and the sequence in which they appear depends on the Sensor Model and the purchased options.
A function variable is expressed as a word or as a number. A function variable may be changed from State A to State B or from a higher or lower numerical value by using the Up / Down arrows.
Operation
86
Rev. L6 Feb 2017 Modline 5
Momentarily depress the Up or Down Arrow pushbutton to make single digit changes starting with the least significant digit. Keep the pushbutton depressed to quickly change values.
All values are retained in non-volatile memory and are automatically reloaded, in the event of a power loss.
Temperature measurement continues during menu operations and changing of function values. The Analog Output and RS-485 temperature indications continue to reflect changes in target temperatures. When a changed function value that affects the measured and displayed temperature is entered with the ENT pushbutton, the temperature reading at the outputs updates in about 150 milliseconds.

The conversion of the Sensor temperature span from Celsius to Fahrenheit follows the formula: F= (1.8 x Celsius) + 32. Example, a 600°C to 1400°C span converts to 1112°F to 2552°F. All outputs and function settings will be in the same units and correspond to the temperature range selected for display. The appropriate °F or °C indicator will be lit for temperature display and setup adjustments when applicable.

RELY – Alarm Relay Operation
The RELY function configures the operation of the Modline 5 Alarm relay for Normally Open or Normally Closed operation. The Sensor internal relay contacts are available on the Black and Black/White twisted wire pair of the Sensor cable. The Alarm Relay contacts are used to report a Sensor alarm condition.
The sensor self-tests its case temperature, detector assembly temperature, output current flow, etc. The Check function checks internal circuit and detector operation. The optional Dirty Window Detector measures the Sensor’s window condition. One or more out of limit conditions sensed by these tests triggers an Alarm.
Set the relay operation to correspond to proper and safe use of the contacts in your overall measurement system. Select N C. for closed relay operation with Sensor not in Alarm condition (open in alarm state). Select N.O. for closed relay operation with Sensor in Alarm condition (open when not in alarm condition).
Contacts are open for both N.O. and N.C. operation when the Sensor is not powered, and, for the 3 to 5 seconds after power is applied during the initiate period.
Normally Closed N.C, operation is considered fail-safe operation.

5.6.6 CHK – Manual System Calibration for 56 Models

This function checks a Model 56 Sensors performance by initiating a System Calibration Check. When
this function is initiated, the Sensor’s infrared detector signal, internal gain and offset voltages are
checked. First, a flag is closed inside of the unit to block the optical path of the instrument. Operation of the Sensor is determined with no target in the field of view of the infrared detector. Second, a calibration
source with a known radiance is activated inside the Sensor and the radiance is “seen” by the infrared
detector. The response of the sensor electronics to the radiance is compared to an expected value.
If the Calibrate Check determines a Model 56 Sensor requires recalibration, the sensor firmware performs a Self-Calibration adjustment. Typically, only small changes in calibration will occur.
During the Calibration Check, the Sensor Rear Panel TEMP display indicates CAL. The Alarm Led indicator and Alarm Relay remain at their last condition. Target temperature measurement is suspended. The Analog Output is held at its last output value. The Analog Output readings are not derived from real time temperature measurement during Calibration Check function. Peak Picker, Track and Hold and Response time functions are suspended. At the end of the cycle, operation returns to normal and real time temperature measurement resumes.
Temperature indications may shift slightly upon return to normal operation.
A Calibrate Check is required for to insure accurate operation of the Series 56 Sensors and should be performed routinely, every 168 hours or less. The check can be initiated by any of the three methods

10% - 95%
Background:
With most two-color infrared thermometers, an invalid indication is reached when the reduction in signal from the target is greater than 95 percent. When the signal reduction is too great, an invalid condition occurs. This variation can be caused by emission characteristics of the target or the target being too small to completely resolve, as well as obstructions in the sight path (i.e., certain types of smoke). When an invalid condition occurs, an alarm output is provided to indicate the signal variation is too great between the two detectors. While this type of detection method is suitable for many applications, there are some instances where the user wants to adjust the sensitivity level of attenuation.
The Modline 5 attenuation adjustment alarming feature operates independent from the optional dirty window detector, which will monitor the sensor window for contamination. It enables users to monitor any kind of signal attenuation caused by dirty viewports or other external windows. Attenuation alarm settings are configurable from 5 to 95 percent, from either the back panel of the sensing head or from the Ircon ModView program. When an alarm condition is detected, relay outputs provide notification to external process control instrumentation.
When the attenuation adjustment alarming feature is enabled, the user can monitor attenuation levels in a graphical format in the ModView program providing a historical view of the levels. In addition, attenuation levels are available through the Modline 5 RS-485 output fed into an external device.

SOUT – Analog Output Current Range Selection
Modline 5 Sensors provide a selection of one of two analog output direct current ranges, 0 to 20 mA or 4 to 20 mA. This function selects the desired range.
ZERO – Analog Output Zero Scale Temperature Scaling
This function sets a temperature to correspond to the selected Analog Output Current Range minimum
value (0 or 4 mA). This temperature must be within the Sensor’s specified temperature range and is
limited to a maximum value equivalent to 10°F (-12.2°C) below the Sensor full scale temperature, or, 10°F (-12.2°C) below the adjusted Analog Output Full Scale temperature value (explained below). Minimum setting is the Sensor specified zero scale temperature. See notes after FULL explanation for ZERO – FULL °C operation and span setting information.
FULL – Analog Output Full Scale Temperature Scaling
Sets a temperature to correspond to the Analog Output Current Range maximum value (20 mA). Temperature must be within the Sensor specified temperature range and is limited to a minimum value 10°F (-12.2°C) above the Sensor’s specified zero scale temperature, or, 10F° (-12.2°C) above the adjusted Analog Output Zero Scale temperature value (explained above). Maximum setting is the Sensor specified full scale temperature.
For ZERO – FULL span setting. °F and °C operation: The minimum 10° span is calculated by the Sensor in °F. When using °C units, the span will be less than 10° because the Sensor first calculates in °F and then converts to °C. The narrower equivalent °C span is allowed. Spans more than 30°C (60°F) may be required to obtain acceptable results. Longer response times may be necessary for very narrow spans to smooth magnified temperature variations and noise.

5.9.5 EMIS – Emissivity Adjustment for Brightness Sensors

Modline 5 brightness sensors and one color operation of ratio sensors require Emissivity adjustment for accurate temperature measurement. The Emissivity value is set to the characteristics of the material being measured using the EMIS function. Ratio sensors that are using the Attenuation Alarm feature will need to set the sensor to a single color mode, set the correct emissivity for the target, then set the sensor back to 2 color mode (When using the Attenuation Alarm feature, you must set the emissivity and also the e-slope for the sensor)
1. Determine the Emissivity value of your target by referring to the instructions in Section 8
Applications Guide, page 129.
2. Select the proper Emissivity value, from the Tables in Section 8 Applications Guide, page 129 for
the surface finish.
3. The adjustable range of the Emissivity is 0.100 to 1.000. See Section 2.3 Model Configuration and
