Equipment Shutdown
To safely complete many of the procedures described in this document, theequipment must first be shut down. The level of shut down required varies bythe type of equipment in use and the procedure being completed. If required, shut down instructions are specified at the start of the procedure.The levels of shut down are:
Relieving System Hydraulic Pressure
Completely relieve system hydraulic pressure before breaking any hydraulicconnection or seal. Refer to the melter‐specific product manual forinstructions on relieving system hydraulic pressure.
De‐energizing the System
Isolate the system (melter, hoses, applicators, and optional devices) from allpower sources before accessing any unprotected high‐voltage wiring orconnection point.
1. Turn off the equipment and all auxiliary devices connected to theequipment (system).
2. To prevent the equipment from being accidentally energized, lock andtag the disconnect switch(es) or circuit breaker(s) that provide inputelectrical power to the equipment and optional devices.
NOTE: Government regulations and industry standards dictate specificrequirements for the isolation of hazardous energy sources. Refer to theappropriate regulation or standard.
Disabling the Applicators
NOTE: Adhesive dispensing applicators are referred to as “guns” in someprevious publications.
All electrical or mechanical devices that provide an activation signal to theapplicators, applicator solenoid valve(s), or the melter pump must bedisabled before work can be performed on or around an applicator that isconnected to a pressurized system.
1. Turn off or disconnect the applicator triggering device (pattern controller,timer, PLC, etc.).
2. Disconnect the input signal wiring to the applicator solenoid valve(s).
3. Reduce the air pressure to the applicator solenoid valve(s) to zero; thenrelieve the residual air pressure between the regulator and the applicator.

HM
CAUTION! Hot surfaces! Avoid contact with the hot metal surfaces ofapplicators, hoses, and certain components of the melter. If contactcan not be avoided, wear heat‐protective gloves and clothing whenworking around heated equipment. Failure to avoid contact with hotmetal surfaces can result in personal injury.
HM
CAUTION! Some Nordson melters are specifically designed toprocess polyurethane reactive (PUR) hot melt. Attempting to processPUR in equipment not specifically designed for this purpose candamage the equipment and cause premature reaction of the hot melt. Ifyou are unsure of the equipment's ability to process PUR, contact yourNordson representative for assistance.
HM, CA
CAUTION! Before using any cleaning or flushing compound on or inthe equipment, read and comply with the manufacturer's instructionsand the MSDS supplied with the compound. Some cleaningcompounds can react unpredictably with hot melt or cold adhesive,resulting in damage to the equipment.
HM
CAUTION! Nordson hot melt equipment is factory tested with NordsonType R fluid that contains polyester adipate plasticizer. Certain hot meltmaterials can react with Type R fluid and form a solid gum that canclog the equipment. Before using the equipment, confirm that the hotmelt is compatible with Type R fluid.

Other Safety Precautions � Do not use an open flame to heat hot melt system components.
� Check high pressure hoses daily for signs of excessive wear, damage, or
leaks.
� Never point a dispensing hand‐held applicator at yourself or others.
� Suspend dispensing handguns by their proper suspension point.
First Aid
If molten hot melt comes in contact with your skin:
1. Do NOT attempt to remove the molten hot melt from your skin.
2. Immediately soak the affected area in clean, cold water until the hot melthas cooled.
3. Do NOT attempt to remove the solidified hot melt from your skin.
4. In case of severe burns, treat for shock.
5. Seek expert medical attention immediately. Give the MSDS for the hotmelt to the medical personnel providing treatment.
HD‐100 Hot Melt Sensor 11
Part 1122177_01� 2013 Nordson Corporation
Overview This manual describes the installation, setup, and operation of the HD‐100hot melt sensor when used with the LogiComm� control system.
The HD‐100 hot melt sensor is a passive, non‐contacting,temperature‐based device. It is used to detect object(s) that are either hotteror colder than the ambient condition, and then activate an output. TheHD‐100 sensor detects the infrared light energy emitted by hot meltadhesive. The sensor uses a thermopile detector, made up of multipleinfrared‐sensitive elements (thermocouples) to detect this infrared energywithin its field of view.

Appendix ASensor Inspection Methods
When the sensor is being operated in conjunction with the LogiComm controlsystem, you can access the sensor specific screens from the Sensor Menuscreen.
Three inspection methods are used to verify products:
� Template verification setting
� Accumulated bead length
� Maximum gap measurements
The following screens are examples of each inspection type.
Template Verification Setting
When initiated by the operator, the engine learns good patterns bymeasuring good products (the number of products is programmable). Fromthis learned data and the tolerances set by the user, a comparison templateis stored in the verification accelerator board.
When verifying normal bead data, sensors are sampled on every encoderpulse and compared to the corresponding template values. If the datacompares favorably to the template data, the product is considered good. Ifproduct data does not match the template within the set tolerance, it isqueued for ejection.
See Figures A‐1 and A‐2 for examples of a good template setting and adefective template setting.

Accumulated Bead Length Setting
The accumulated bead length verification method provides an analysis toolto monitor too much or too little adhesive on the substrate by allowing theuser to set upper and lower limits for the total length of glue in a designatedarea called the measurement zone. A typical application is for the detectionof excessive glue that could cause a squeeze‐out. A squeeze‐out occursduring compression when excess glue seeps out of the glue flap, causing theproducts to stick together.
In using this method, the user designates the measurement zone by enteringthe start position and length of the measurement zone. The user then sets anupper and lower limit to the total amount of measured glue bead over thezone. During the inspection process, the LogiComm control system addstogether each bead segment in the specified region, without consideration ofthe exact location of the segments. The product is determined to be defectiveif the total length of glue bead exceeds the upper limit or is less than thelower limit.
See Figures A‐3 and A‐4 for examples of a good accumulated bead lengthsetting and a defective accumulated bead length setting.

Maximum Gap Setting
The maximum gap verification method provides an analysis tool that inspectsfor gaps in the adhesive bead that exceed a user‐specified maximum. Atypical application for maximum gap verification is for the inspection ofwheel‐applied glue where railroad tracks, or broken beads are common, andwhere the critical quality control measure is to ensure that gaps in the glueare not excessive in order to ensure bond integrity.
In using this method, the user designates the measurement zone by enteringthe start position and length of the measurement zone. The user then sets amaximum gap length limit. During the inspection process, the LogiCommsystem inspects over the user‐specified region, comparing each gap in theadhesive bead to the maximum limit, and without consideration of the exactlocation of the gaps and segments. The product is determined to bedefective if any gap exceeds the maximum gap limit.
See Figures A‐5 and A‐6 for examples of a good maximum gap setting and adefective maximum gap setting.
