The mating socket (part no. 933 121) for this plug is used on all hot melt hoses for non-circ-

ulating units.

Both plug and socket will be supplied initially on all of the guns listed above.

Plug is available separately as an assembly (part no. 933 120). This includes the plug assembl y I

and I” cable protector.

The plug is also included in the connector assembly (part no. 153 036). This includes the

insulation sleeve, 18” wire, and the explanation tag.

An explanation tag is attached to each plug assembly. The tag reads as follows:

NOTICE

A new and improved electrical connection between hose and gun is furnished

with this equipment.

For your convenience, both plug (part no. 933 120) and socket (part no. 933

are furnished so any existing equipment can be updated.

121)

For safety, the socket (part no. 933 121) must be attached to the hose and plug

(part no. 933 120) attached to the gun.

To update existing equipment, proceed as follows:

a. Remove old plug and/or socket by cutting wires where they enter

plug or socket.

b. Strip l/4” insulation from end of each wire.

C. Using solder suitable for electrical equipment, solder each wire from hose

to different terminals on socket. Solder each wire from gun to seperate

terminal on plug.

d. Install covers over insulators. Insert drive screw into hole in cover and

insulator. Tap lightly to seat.

e. Discard old plug and/or socket.

ED6 ONLY OPTIONAL CARTRIDGE HEATERS

FOR HOT MELT GUNS

Frequent field requests for optional hot melt gun cartridge heaters has resulted in the gun heater option chart shown below. The reason options are requested usually is to provide a higher wattage heater than originally furnished with the gun.

There are several important things to consider before using or attempting to use an optional gun heater.

1. Optional heaters are not available for H2OE (240 683), H20L (240 305), H21A (153 100) and H21L (240 310) guns.

2. Some optional cartridge heaters will require wire length changes. a. To shorten - simply cut wire to desired length.

b. To lengthen - splice on high temperature wire using ceramic electric connectors. En- sure the wire splices are contained within the gun wire cavity. This may require the wires on the cartridge heater to be shortened first.

ARMORED CORDSET RETROFIT KITS FOR AUTOMATIC HOT MELT GUNS AND HOSES

Nordson has established four armored cordset retrofit kits to update old style guns and hoses (with plug and socket electrical connector).

1. Retrofit kit 241 907 should b e used for updating the e lectrical connect ion when both the hose and non-circulating guns are the old style, e .g . the gun has a pl astic cordset and the hose has an electrical socket connector.

Armored cordsets have replaced the plastic cordset (with plug and socket electrical connector) on all H3, H9 and H20 automatic guns and hoses. The armored cordset wi II provide an electrical

connection between the gun and hose which is safer and acceptable to approval agencies.

2. Retrofit kit 242 566 should be used when the old style hose, (with an electrical socket connector) is attached to a new style gun with an armored cordset.

NOTE: Retrofit kit 242 566 must be purchased separately, it is not included with the gun.

3. Retrofit kit 242 567 should b e used when the old style H20A and H20L guns (with a plastic cordset) are attached to a new style hose.

NOTE: Retrofit kit 242 567 must be purchased separately, it is not included with the hose.

4. Retrofit kit 242 870 should be used when the old style H3, H9 and H20B guns (with a plastic cordset) are attached to a new style hose. This kit used for circulating and non-circulating guns.

NOTE: Retrofit kit 242 870 must be purchased separate1 y, it is not included with the hose.

ARMORED CORDSET HOLDER- HOSE COLLAR INTERFACE

The electrical leads connecting the hot melt gun armored cordset to the hot melt hose must be isolated from each other.

There are two styles of hose col iars used: The hand gun hose collar has no molded ribs isolating the electrical terminals. The automatic gun hose collar has two molded ribs isolating the three

electrical terminals.

Use the armored cordset retainer that provides electrical isolation between the leads.
