2300 RETROFIT MELTER FEEDER KIT
INTRODUCTION
The 2300 Retrofit Melter :Feeder Kit is designed to convert the
2300with the Robert Shaw Controller, 2000 Series, Model IV,
Model V, Model VII and Model IX Melter Feeders to the new 2300
Melter Feeder. The new Melter Feeder is more user friendly and ef-
ficient. This improved performance is a result of the new Hood
and Chute Assembly design and the addition of the Rechner
Sensor.
UNPACKING
Carefully remove the kit components from the shipping container
and compare them with the list provided below. Inspect the com-
ponents for obvious signs of damage. If damage is found, contact
your Nordson Sales representative.

A
applicator.
WARNING: Failure to disconnect external power to
the Melter Feeder or to the applicator presents a
serious shock hazard. This procedure requires con-
tact with wires and electrical components of the Mel-
ter Feeder and the applicator.
WARNING: Wear safety glasses, safety gloves (P/N
902 514), and protective clothing to prevent injury
from hot applicator parts or splashed hot melt ad-
hesive material.
3. Remove the screws holding the hood to the grid.
4. Remove the plate from the Material Level Probe Assembly. Dis-
connect all wires.

PARENT MACHINE INTERLOCK 1NSTALLATI:ON
Description of Parent Machine Interlock
A Parent Machine Interlock performs two basic functions: it
provides a way for an operator to tell when the adhesive in the
tank has reached application temperature (an indicator light turns
off) and, once this temperature is reached, it energizes a contact
which may be used to operate a nolrmally open or a normally closed
switch on a parent machine. If, for example, a system user wants
to ensure that a packaging line does not run unless the adhesive is
fully melted, a PM1 can be used to achieve this purpose.
Installation of PM1 1. Disconnect and lock out input electrical power.
WARNING: Disconnect and lock out external power
to the applicator beforle opening the electrical
enclosure. The input terminal board and the input
terminals on the main circuit breaker are still electri-
cally energized if external power is not disconnected,
even though the circuit breaker on the front of the
applicator is turned off.
WARNING: DO NOT touch the black heat sinks ex-
tending from the green circuit board when power to
the unit is on. They are electrically energized and
therefore present a shock hazard.
2. Remove the electrical control cabinet enclosure by unscrewing
the captive screw on top of the cabinet.
3. Locate the two-part terminal block at the bottom of the PM1 cir-
cuit board (see Figure 8). While holding on to the receptacle
part of this terminal block, carefully pull on the plug part of
the terminal block until the two parts separate.
4. To obtain working room, unplug the white plugs along the top
of the main circuit board (there will be two of these on a Model
2302, four on a 2304, and five on a 2305).
5. Remove the two screws that secure the main circuit board to
the base of the applicator.
6. Tilt the top part of the circuit board away from the applicator
until it inclines at approximately a forty-five degree angle. DO

NOT try to remove the board from the applicator completely be-
cause it is still connected. by wires at several points.
7. Carefully attach the PM11board to the main circuit board by in-
serting the four pins into the pin connectors on the main board.
(See Figure 8 for approximate locations of pins). Make sure
that all pins are securely in place. The pins connect the PM1
board to the main board ‘both physically and electrically.
8. Take the light connected to terminals 1 and 2 of the plug and in-
sert it into the top slot on the main circuit board (see Figures 8
and 9). Secure it in place by wedging the rubber collar around
the light into place (it may be helpful to use a screwdriver for
this purpose).
9. Using the plug that was removed from the PM1 board in step 3,
connect the leads in either order (the PM1 is not polarity sensi-
tive) to terminals 3 and 4 on the plug if a normally closed
switch is to be controlled; connect them to terminals 4 and 5 if
a normally open switch is to be controlled. (See Figure 8 for ter-
minal numbers).

NOTE: The contacts are rated for 250 volts,

10. Reconnect the plug of the two-part terminal block to its recep-
tacle at the bottom of the PM1 board.
NOTE: Make sure that the PM1 board is still
securely connected to the main circuit
board at all four pin locations. The pins con-
nect the PM1 board to the main board
electrically as well as phy:sically.
11. Return the main circuit board to an upright position and
secure it to the base of the applicator with the two screws
removed in a previous step.
12. Reconnect the white plugs to their receptacles along the top of
the main circuit board. Connect the plug labeled 1 and to the
connector labeled Jl on the circuit board, plug No. 2 to connec-
tor 52, and so forth, until all plugs are connected.

13. Move the active/inactive switch on the PM1 (see Figure 8) to
the left if it is desired to have the PM1 inactive after the initial
startup sequence; move the switch to the right if it is desired
to have the PM1 active after the initial startup sequence. For a
detailed description of htow the PM1 operates in both the active
and inactive modes, see your applicator owners manual
14. Set the adjusting screw on the PM1 board (see Figure 8) to ob-
tain the desired delay cycle. Fully counterclockwise is 12
minutes, the maximum delay possible. Straight up and down is
about 17 minutes.
LEVEL CONTROL SENSITIVITY ADJUSTMENT
1. Locate the level control potentiometer and red indicator LED
on the lower panel of the level controller inside the electrical
control box.
A WARNING: This (equipment contains energized
‘I electrical components with potentials that could be
fatal. Only qualified personnel should operate this
equipment.
2. While checking through lthe modified 2300 Melter Feeder lid
door, press and hold in the Manual Fill button to activate the
heated grid. Observe the flow of adhesive from grid into the
hood and applicator tank..
A WARNING: Wear safety glasses, safety gloves, and
protective clothing to prevent injury from hot ap-
plicator parts, splashed hot melt adhesive material
and hot gun surfaces.
NOTE: The FILL ind.icator LED should
remain lit while the button is held in.
3. Allow enough adhesive to fill the applicator tank until the level
of adhesive is 1 inch (25.4 mm) below the sensor probe, or ap-
proximately 2 inches below the metal cover on the 2300 unit,
then release the Manual Fill button
4. Use a small screwdriver to locate the sensitivity scale mid-
range by turning the level control pot at least 15 turns in one
direction, and 7 or 8 turns in the other direction.

NOTE: This procedure must be followed be-
cause there are no stops or “clicks” when the
adjustment pot reaches the end of the
range. Turning the pot at least 15 turns in
any one direction assures that the end of
the range is reached.
NOTE: DO NOT touch the sensor cable in-
side the control unit. Touching the cable
may activate or deactivate the heated grid.
5. From this point, turn the pot until the red indicator LED goes
on and all indicator LEDs go off’.
NOTE: With the level control sensitivity
properly adjusted, the Melter Feeder fill se-
quence will begin and remain on until the
adhesive level is within 1 inch (2.54 cm) of
the sensor.
NOTE: If adhesive builds u.p on the sensor,
it may be necessary to increase the level
control sensitivity or to clean the sensor
lens.
