Connect Applicators
Observe the following guidelines:
DuraBlue II melters with 120‐ohm nickel sensors support all Nordson
T‐style applicators. DuraBlue‐II melters with 100‐ohm platinum sensors
support all Nordson M‐style applicators.
For information about choosing the most appropriate Nordson hot melt
applicator for your manufacturing process, refer to the latest edition of
Nordson's hot melt dispensing equipment Replacement Parts Catalog or
contact your Nordson representative. Refer to Appendix A, Calculating
Melter Power Requirements, for information about how to calculate the
power required by Nordson hot melt applicators.
Refer to the user's guide that is shipped with each applicator for
information about installing the applicator and connecting a hose to the
applicator.
NOTE: DuraBlue II adhesive melters are shipped with a 0.2 mm hot melt
filter installed in the manifold. Order the appropriate applicator nozzle based
on this filter mesh size.

Setting Up the Melter
After physically installing the melter, it must be set up to support your
manufacturing process. Melter setup consists of enabling or making changes
to factory‐set operating parameters that affect the use and function of the
melter. The operating temperature (set‐point) of the tank and each hose and
applicator is also established during melter setup.
The melter is shipped from the factory with the most commonly used
operating parameters already set up. The factory setup can be modified at
any time to suit your manufacturing process.
Quick Setup
Table 3‐2 describes the most commonly used operating parameters and their
factory settings. Review the table to determine if the factory settings for each
parameter will support your manufacturing process. If the default values for
each of these operating parameters are appropriate for your manufacturing
process, then no melter setup is required. Go directly to Set‐point
Temperature of the Tank, Hoses, and Applicators later in this section to
complete the installation process.
If you need to make changes to the factory setup or if you want to learn about
other operating parameters, go to the next part in this section, Operating
Parameters.

Parameter Parameter Name Purpose Default Value
4 Ready Delay Time
A timer that delays the activation of the ready LED for
a pre‐defined time period after the tank, hoses, and
applicators are at the desired set‐point temperature.
The ready delay timer will only activate if the
temperature of the tank, at the time the melter is turned
on, is below its assigned set‐point temperature by
27 C (50 F) or more.
0 minutes

Service Interval
Time
A timer that turns on a service LED when the value set
for the timer equals the number of hours that the
heaters have been on. The service LED is used to
signal the need for maintenance.
500 hours
7 Motor Off Delay
If the switch receptacle is used, this parameter
determines the amount of time the motor will remain
on after the switched device is turned off.
0 seconds
8 Automatic Pump On
Allows the pump to start automatically when system
ready is reached, provided that the pump has been
enabled by pressing the pump key.

Over Temperature
Delta
Sets the number of degrees that any heated
component can exceed its assigned set‐point
temperature before an over temperature fault occurs.
15 C (25 F)
22
Under Temperature
Delta
Sets the number of degrees that any heated
component can drop below its assigned set‐point
temperature before an under temperature fault occurs.
25 C (50 F)
23 Standby Delta
Sets the number of degrees that the temperature of all
heated components will be decreased when the melter
is placed into the standby mode.
50 C (100F)

Manual Standby
Time
Sets the amount of time the melter will remain in the
standby mode after the standby key is pressed.
