How to Check RTD Resistance on Nordson Cordset

If your Nordson unit is displaying a fault for the RTD and you have already verified all connections are secure, follow these steps to check the RTD Sensor:


First, find out the temperature of the RTD to perform this check properly.
  • ·     Disconnect and lock out electrical power to the system.
  • ·        For the RTD being checked, disconnect the cordset that supplies power to RTD.
  • ·        Refer to Figure 11-7 or 11-8 as appropriate.  With the RTD at a know temperature, us an ohmmeter to measure the RTD resistance at the RTD pins at the cordset connector.
  • ·        Refer to Figure 11-9 to determine the correct resistance for the RTD base on its temperature.
    • o   If measured resistance is correct, the RTD is operating properly.
    • o   If measured resistance indicates an open circuit, continue to the next step.
  • ·        Remove the cordset connector hood and check for loose RTD wires or wire connections.  Tighten any loose connections.
  • ·        Check the RTD resistance again.  If the resistance is correct, the RTD is operating properly.  If resistance indicates an open circuit, continue to next step.
  • ·        Disconnect the RTD wire, measure the resistance across the wires and compare the results to Figure 11-9:

o   If measured resistance is within appropriate range, reconnect the RTD wires, reinstall the cordset connector hood and recheck the resistance at the RTD pins on connector.
o   If measured resistance is not within the appropriate range, replace the RTD.

ProBlue F1 Fault for Failed RTD Sensor

The Nordson ProBlue melters will display a F1 fault light when the tank RTD has failed.  

But, first before going the route of replacing the RTD Sensor, verify that all connections are secure.  This fault code will also display if you have a loose connection.  Check the electrical connection for the hoses at the tank end and the electrical connection between the hoses and applicators.  

Once you have determined that you have secure connections and the F1 fault is still displaying, replace the tank RTD sensor.  Click here for replacement instructions.

Keystone supplies a RTD Sensor kit for $40.  It is recommended that one of these be kept in stock to prevent more downtime than is needed.  This kit is also used on the Nordson Mesa melters.

Are you still having issues with your melter?  Please call us at 800-235-8090 for free technical assistance.

Glue Hoses and Proper Hydraulic Fittings

Did you know that you can damage the electrical wire in a glue hose by not using the proper hydraulic fittings?

If you bend a hose too much, the wires can be compromised and can bend or break.  Once this occurs, the hose is no good.  

Keystone Industries offers fittings that are straight, 45° and 90° so you can make sure your hoses are not in a bind.  You have a fitting at the melter manifold and a filter fitting at the applicator head.

Not sure which ones are right for your melter hose?  Give us a call and we can help you.

Washdown Nordson Glue Hoses

Do you wash down your packaging lines?  Are you continually having issues with glue hoses electrically shorting?  You may be using standard glue hoses in a wash down environment. 

If so, Keystone Industries has a solution that will save you money by reducing downtime and reducing the number of glue hoses you purchase in a year.  Wash down hoses are water resistant and will last longer in wash down environments.

With an outside rubber sheathing to protect the electrical wiring and a round threaded electrical connector to seal off the electrical pins, the wash down style hose will resist the wet environment.  Of course, we do not recommend you use high pressure water spray directly on the hoses, but the hoses are resistant to over spray from the high pressure spray and moisture in the air.

Call us today to find out how to switch out the standard hoses to the wash down style.

Safety First - Replace Your Frayed Glue Hoses

As you know, safety is top priority in manufacturing plants.  If your glue hoses are fraying, it is time to replace them to maintain a safe working environment.  

To prevent fraying of glue hoses, verify you have the correct length hose.  

Many hoses that are too long become frayed as a result of being stepped on or being run over because they are lying on the floor.

On the other hand, verify the hose is not too short.  If a hose is too short and is rubbing up against a sharp edge, fraying can occur.

If you would like to change the length, please let us know and we can help with providing pricing and a part number for the length hose you need.

Cartridge Heaters for Nordson Glue Guns

Stocking cartridge heaters for the Nordson, Slautterback, Melton,  and ITW applicator heads is good planning to reduce downtime when a heater goes out on a glue applicator head.

We suggest keeping one of every variety of applicator heads you use on the shelf, but keep several cartridge heaters. You can install the head you have on the shelf and repair the failed gun by replacing the heater and put the repaired head on the shelf.

There are many size heaters, wattage's and voltages.  Please let us know if you need help determining what you need.

Nordson Glue Applicator Not Heating?

Continuing on our subject from yesterday......

Recap:  Yesterday, we discussed if the glue applicator head failing, troubleshooting to verify the head failure and went from there.

Today:  Let's say the supposed "failed" applicator head is moved to another channel and performs as it should.....now what?

There could be an issue with the hose.  Take the suspect hose and move it to a working channel on the glue melter.  If it fails, you know you need a new glue hose.  If it works, then troubleshooting the Nordson circuit board(s) is next.  Stay tuned.....

Let us know if you need a new hose.

Nordson Gun not heating

Needing some assistance with a glue applicator head that is not heating?

May not be your applicator head at all.

Start with installing the head on another hose where you know the head works.  If the head fails there, then you can surmise it is the head.  If the head works, then you may have a hose or circuit board issue.

If the head failed, you can check the heater for continuity.
Depending on the type of melter you have, check either the thermostat or RTD Sensor.

Once you find the issue, you can replace the failed part in the gun, saving you from having to spend the big bucks on the complete head.

Keeping these small components in stock can reduce your downtime when a head fails.

Please call us if you need free technical help.
