To adjust the setpoint temperature of an individual component
1. Press and hold the Tank, Hose, or Applicator key for three seconds.
If the tank key was pressed, the left display indicates 1 (Flashing). If a
hose or applicator key was pressed, the left display indicates the number
of the first sequential hose or applicator (Flashing). The right display
indicates the current set‐point temperature of the component indicated in
the left display.
2. Scroll the left display to the number of the desired component.
The right display indicates the current set‐point temperature of the
component that you selected in the left display.
3. Press the Enter key.
The right display flashes.
4. Use the keypad to enter the set‐point temperature recommended by
the manufacturer of the hot melt. Refer to the technical data
sheet provided by the manufacturer of the hot melt to determine the
optimal set‐point temperature.
NOTE: If the keypad or the right‐display scroll keys have no affect on the
right display, the melter is password protected. You must enter a valid
password before you can change set‐point temperatures. Refer to
Entering a Password in this section.
5. Do one of the following:
To register the new set‐point temperature and then move on to
change the set‐point temperature of the next sequential component,
press the Enter key and then repeat steps 4 and 5.
To register the new set‐point temperature and return to the automatic
scan mode, go to step 6.
6. Press any component key (tank, hose, or applicator).
The selected component begins to heat or cool to its new
set‐point temperature.

If you enter a valid set‐point temperature for a
hose/applicator that is not connected to the melter or if
you enter a set‐point temperature that is out of range,
the right display will indicate dashes (‐‐‐‐) for three
seconds and then change back to the original
set‐point temperature.
When the right display is flashing, you can quickly
change the current set‐point temperature to 0 degrees
(off) by simultaneously pressing both of right‐display
scroll keys.
After removing a hose or a applicator, use
the individual component method of set‐point
temperature adjustment to set the component's
temperature to zero degrees (off). This will
avoid causing an F1 fault. When a hose or applicator
is added, use the individual component method to set
the desired temperature.
The factory set‐point temperature of the tank is 175 C
(350 F). The factory set‐point temperature of all others
components is zero degrees (off).
When the units of temperature is set to degrees
Celsius, the minimum and maximum set‐point
temperatures are 40 C and 230 C. When the units of
temperature are set to degrees Fahrenheit, the
minimum and maximum set‐point temperatures are 100
F and 450 F.
When using the right‐display scroll keys to adjust a
set‐point temperature, the right display automatically
increments between 0, 175, and 230 C or between 0,
350, and 450 F.
If you make a mistake while you are changing a
set‐point temperature, but you have not yet pressed the
enter key, press the Clear/Reset key to reset the right
display to the original temperature.
The melter will exit the setup mode and return to the
automatic scan mode two minutes after the last key is
pressed.
A global set‐point temperature of zero degrees (Celsius
or Fahrenheit) turns all components off.
When scrolling through component numbers in the left
display, component numbers that are associated
with unused hose/applicator receptacles are skipped.
The melter stores a record of the last ten changes
made to the set‐point temperatures (and operating
parameters) in the change history log.

Entering a Password
If the melter is password protected, a valid password must be entered before
any set‐point temperature or melter parameter can be changed.
To enter a melter password
1. Press the Setup key.
The left display indicates Parameter 0 (flashing) and the right
display indicates 4000.
2. Press the Enter key.
The right display begins flashing.
3. Use the keypad to enter the melter password.
4. Press the Enter key.
One of the following occurs:
If the password is correct, the left display indicates Parameter 1.
If the password is incorrect, the left display remains at 0 and the
right display momentarily indicates dashes (‐‐‐‐) and then returns to
4000.
If the password is incorrect, re‐enter it and then press the Enter key.
The melter will automatically revert back to the
password‐protected mode two minutes after
the last key press (any key). To force the
melter back into the password protected mode
before two minutes has elapsed, press the
Setup key twice.
The melter password is created and
enabled/disabled during system setup.
