Description Nordson MiniBlue automatic guns apply thermoplastic hot melt adhesive toa product, providing uniform bead deposition and improved cutoff whenused with aggressive or hard-to-dispense adhesives. Their air-open,air-close dispensing modules allow high cycle speeds and their compactsize allows them to fit between the flaps of most cartons.

MiniBlue guns are available in a slim,18-mm (0.71-in.) single-module designand in a variety of configurable designs, including single-module andmulti-module configurations. MiniBlue guns are manufactured according tothe design choices made at the time of order placement. Refer to GunConfiguration Code under Technical Data at the end of this manual for moreinformation.

Figure 2 shows some typical MiniBlue guns. Figures 3 and 4 show the keyparts of two typical MiniBlue guns.

NOTE: The illustrations in this manual depict typical MiniBlue guns. Yourgun may differ in appearance.

Solenoid Valve See Figure 5. MiniBlue guns use either small SD solenoid valves or largeSG solenoid valves:

� If the production line speed is 90 m/min (295 ft/min) or less, eitherSD or SG solenoid valves may be used.

� If the production line speed is greater than 90 m/min (295 ft/min),only SG solenoid valves may be used.

Solenoid valves may be configured for independent, common, orprogrammed module actuation, as described in Table 3.

Table 3 Types of Module Air Actuation

Type of Actuation Description

Independent One solenoid valve directly actuates onemodule

Common One solenoid valve actuates all modules.

NOTE: SD solenoid valves may not beused in common air gun configurations.

Programmed Two solenoid valves actuate actuate twogroups (left and right) of modules

NOTE: For the best module performance in intermittent applications,Nordson Corporation recommends the use of one solenoid valve permodule (independent actuation). Module performance will be sacrificedproportionately as more modules are controlled by a single solenoidvalve (common or programmed actuation).

Dispensing Module See Figure 6. MiniBlue guns use either reduced-cavity or ball-and-seatdispensing modules:

� Reduced-cavity modules have an integral nozzle and are virtuallyself-cleaning. The modules are available with 0.20, 0.30, 0.41, and0.51 mm (0.008. 0.012, 0.016, and 0.020 in.) nozzle orifice sizes.

� Ball-and-seat modules are used in combination with Saturn nozzles,allowing easier change-out of nozzle sizes and eliminating the needto stock multiple reduced-cavity modules with different orifice sizes.

A MiniBlue gun may have 1−8 modules. Air is supplied constantly to amodule through a solenoid valve. When the gun is not being triggered, airwill flow through the module’s air-close port to keep the module needle onits seat. When triggered, the solenoid valve will direct air into the air-openport, lifting the needle from its seat to dispense the adhesive.

42150061 2 3

EasyOn Feature All MiniBlue gun modules use the EasyOn� feature. The EasyOn featureon the module, mates with the EasyOn feature on the gun body.The EasyOn feature allows the module to be installed onto the gun body,regardless of the orientation of the gun body.

MiniBlue� Guns16


Hose Connector/Filter See Figure 7. All MiniBlue guns have a straight, 45-degree, or 90-degreehose connector and either an integrated or an inline Saturn filter. Saturnfilters use a configurable screen.

� On slim single-module guns, the filter is integral to the gun and islocated just below the hose connector.

� On single- and multi-module configurable guns, the filter is inline withthe hose connector.

Temperature Control All MiniBlue guns use 120-ohm nickel resistance temperature detectors(RTDs) for precise temperature sensing and for gun temperature control towithin ±0.5 �C (1.0 �F) of a setpoint temperature.

Intended Use MiniBlue guns are specifically designed for industrial applications thatrequire the deposition of a precisely controlled bead of hot melt materialonto a moving substrate. The guns are designed to be rigidly mounted,pneumatically operated, and triggered by a Nordson-approved, electricallycontrolled solenoid valve. MiniBlue guns are designed for use with Nordsonmelters and hoses.

Auxiliary Devices and Spare Parts MiniBlue guns should only be connected to approved auxiliary devices. Useonly new Nordson replacement parts or approved factory refurbished parts.

substrate, but at a distance that works best for your application.Typically, the minimum distance is two times the diameter of the nozzleorifice.

� Ensure that the mounting location provides sufficient clearance aroundthe rear or sides of the gun to allow for removal of the manifold covers.

� Mount the gun on a rigid support that is isolated from external vibrationsand that prevents the gun from rotating.

� Insulate the gun from the support using the insulator provided with thegun.

Hydraulic and Pneumatic Connections � Use only one fitting to connect a hose to a hose connector on the gun.

� Insulate hose-to-gun joints. Insulating cuffs may be ordered separately.Refer to Parts.

� Use only clean, dry, non-lubricated air.

� Ensure that the plant air supply and regulator provide a minimum of4 bar (58 psig) to the gun solenoid valve.

Unpacking and Inspection 1. Carefully unpack the gun.

2. Inspect the gun and inventory the contents of the shipping package.Guns are shipped fully assembled and typically include the followingcomponents:

� mounting clamp� module(s)� solenoid valve(s)

Guns ordered with optional features may be shipped with additionalcomponents.

MiniBlue� Guns20


Mounting the Gun This section describes the following gun-mounting options:

� mounting a gun on a new or existing system� replacing a gun on an existing system

The configuration of your equipment and production line may require avariation in the mounting options described in this section. Regardless ofthe mounting method used, follow the guidelines provided in InstallationGuidelines.

Mount a Gun on a New or Existing System1. See Figure 9. Slide the gun mounting clamp(s) onto a 12-mm, 13-mm,

Nozzles 0.20, 0.30, 0.41, and 0.51 mm (0.008, 0.012, 0.016, and0.020 in.) reduced-cavity modules; all Saturn nozzles

D

Electrical service 240 VAC, 50/60 Hz

Solenoid valve power supply 24 VDC only E

NOTE A: MiniBlue gun modules operate as air-open, air-close valves. The loss or elimination of air pressure to thegun solenoid valve without a corresponding reduction in system hydraulic pressure may cause the gunmodules to remain open.

B: System hydraulic pressures are application-dependent. Variables such as the adhesive type and productline speed must be considered when establishing an optimum system hydraulic pressure.

C: Use dry, regulated, unlubricated air for consistent gun operation.

D: On reduced-cavity guns, the nozzle is an integral part of the gun module.

E: Contact your Nordson representative to use an alternate power supply.

Table 9 Explanation of Gun Configuration Code Positions (see Figure 38)

CodePosition Description Code Values

1 Gun model H100

2 Number of modules 00 = slim single-module gun (18 mm), 1 module01 = Configurable single-module gun (40 mm), 1 module02−08 = Configurable multi-module gun, 2−8 modules

3 Module type R08 = reduced cavity, 0.20 mm (0.008 in.)R12 = reduced cavity, 0.30 mm (0.012 in.)R16 = reduced cavity, 0.41 mm (0.016 in.)R20 = reduced cavity, 0.51 mm (0.020 in.)STD = H100B, ball-and-seat

4 Cordset type T = standard RTDW = water-resistant RTD

5 Cordset position BS = slim single-module gunLS = left side (configurable guns only)RS = right side (configurable guns only)LB = left back (configurable guns only)RB = right back (configurable guns only)

6 Air supply configuration CA = common air (see Note B)IA = independent airPA = programmed air (two module groups only)

7 Hose connector/inline filter angle(see Note A)

F0 = no angleF4 = 45� angleF9 = 90� angle

8 Additional hose ports (all guns havethree hose ports)

3 = one hose port on each end and one centered on back5 = one hose port on each end and three on back (one inthe center and one at each end)

9 Solenoid valve type(see Notes B and C)

SD = line speeds ≤ 90 m/min (295 ft/min)SG = all line speeds

10 Voltage A = 230 VACB = 200 VAC

11 Programmed air groups PA = programmed air (two module groups only)

NOTE A: On slim single-module guns, the hose connector is located just above the integrated filter. On single- ormulti-module configurable guns, the filter is inline with the hose connector.

B: SD solenoid valves may not be used in common air gun configurations.

C: If production line speed is �90 m/min (295 ft/min), use either SD or SG solenoid valves. production linespeed is >90 m/min (295 ft/min), use only SG solenoid valves.
