Description
- With the exception of tank capacity, hose/gun capacity, and exterior appearance, all ProBlue melters are functionally identical. To simplify the presentation of information in this manual, depictions of the model P4 are used generically throughout this manual to represent all ProBlue melters
Product Description
- The melter liquifies solid‐form hot melt and maintains the hot melt at the desired temperature. When the guns are activated, the melter pumps the liquified hot melt through the hoses and out the gun nozzles, where it is commonly applied to the surface of a product or package.
- ProBlue melter
- Hot melt gun
- Hot melt hose
Modes of Operation
ProBlue melters operate in the following modes:
- Automatic scan—The melter automatically checks and displays the current temperature of the tank, hoses, and guns to confirm that they are within their pre‐defined temperature range. By default, the melter is always in automatic scan mode unless it is placed in another operating mode.
- Standby—The temperatures of the tank, hoses, and guns are reduced from their operating temperature (hereafter referred to as set‐point temperature) by a pre‐set number of degrees.
- Setup—The setup mode is used to configure melter control options and features and to review stored operating data. To prevent unauthorized changes to the melter’s configuration, the melter can be password‐protected
- Fault—The melter alerts the operator when an abnormal event occurs.

Section 3
Installation
Overview
- ProBlue melters are factory‐configured for each order and require only the assembly and set-up tasks described in this section. If your melter was ordered as a complete system, the shipping container will also contain one or more hot melt hoses and guns. ProBlue 400/480-volt melters include a transformer assembly that is shipped separately from the melter.
- The melter is shipped from the factory with an installation kit that contains components that must be assembled onto the melter by the customer. Some additional materials must also be supplied by the customer to complete the installation.
Installation Requirements
- Before installing the melter, ensure that the desired installation location provides the required clearances, environmental conditions, and utilities.
- Clearances
- Figure 3‐1 illustrates the minimum clearances that are required between the melter and surrounding objects. Table 3‐1 describes each clearance
- Table 3‐1 Installation Clearances
Item Description Required Clearance A
The distance from the outside edge of a 5/16‐inch Nordson hose to the front face of the melter when a short 90‐degree hose fitting is used to connect the hose to the melter P4 = 370 mm (14.5 in.) P7 = 370 mm (14.5 in.)
P10 = 391 mm (15.4 in.)
B
The clearance required to open the pump enclosure door P4 = 243 mm (9.6 in.) P7 = 243 mm (9.6 in.)
P10 = 268 mm (10.55 in.)
C
The distance from the melter sub‐base to the front edge of the tank lid when the lid is at its highest point. P4 = 502 mm (20.0 in.) P7 = 564 mm (22.2 in.)
P10 = 656 mm (26.0 in.)
D
The clearance required on the left side of the melter to open the electrical enclosure door or remove a hose/gun module. P4 = 648 mm (25.5 in.) P7 = 711 mm (28.0 in.)
P10 = 714 mm (28.1 in.)
Other Considerations
Consider the following additional factors when evaluating where to install the melter.
- The maximum distance between the melter and each gun is dictated by the power requirement of each hose. Refer to Appendix A, Calculating Melter Power Requirements, for information about how to determine the maximum allowable length.
- The operator must be able to safely reach the control panel and accurately monitor the control panel indicators.
- The operator must be able to safely observe the level of hot melt inside the tank.
- The melter must be installed so that it can be safely removed from its sub‐base.
- The melter must be installed away from areas with strong drafts or where sudden temperature changes occur.
- The melter must be installed where it will be in conformance with the ventilation requirements specified in the Material Safety Data Sheet for the hot melt being used.
Unpacking the Melter
- Before starting the installation, remove the melter from the pallet, locate the installation kit, and inspect the melter for damaged and missing parts. Report any problems to your Nordson representative.
Contents of the Installation Kit
- The installation kit provided with the melter contains the components shown in Figure 3‐3. The quantity and type of hose fittings provided in the kit depends upon the melter’s model number and configuration.
- NOTE: 400/480 volt transformers are shipped with a separate installation kit. Refer to Appendix E for information about the contents of the transformer
installation kit. The installation kit also contains a package of safety label overlays that are printed in a variety of languages. If required by local regulations, the
appropriate language overlay should be applied over the English version of the same label. Refer to Section 1, Safety Labels and Tags, for the location of each safety label
Mounting the Melter (contd)
Configuring the Electrical Service (contd)
- WARNING! Risk of electrocution! Install a lockable power disconnect switch between the electrical service and the melter. Failure to install or properly use the disconnect switch when servicing the melter can result in personal injury, including death.
- Open the electrical enclosure door.
- Route the power cable into the wire tray in the base of the electrical enclosure.
NOTE: If the power cable cannot be routed through the conduit knockout provided in the sub‐base (Refer to Mounting the Melter earlier in this section), route the cable through the optional knockout provided on the left side of the chassis. See Figure 3‐5. - Connect each power cable lead to the appropriate terminal on the electrical connector (P/N 1022993). Table 3‐3 describes the terminal connections for each type of electrical service.
- Plug the electrical connector into receptacle TB1 on the main board.
- Connect the ground lead from the power cable to the ground lug that is located on the chassis. The lug is marked PE/G.
- Connect the ground jumper that is connected to the ground lug, to the ground post that is located on the sub‐ba

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 gun 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
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 guns 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
5
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

Operating Parameters
- The melter uses operating parameters to store noneditable and editable values. Noneditable values are those that provide information about the historical performance of the melter. Editable values are either a numeric set‐point or a control option setting. Control options settings affect the display of information or the function of the melter.
- Operating parameters are stored in the melter’s firmware in the form of a sequentially numbered list. The list is organized into the logical groups described in Table 3‐5.

Installing Melter Inputs
ProBlue melters are equipped with four standard inputs. Each input is customer‐wired to the melter and then set up to provide one of the following control options:
- Place the melter into standby mode
- Turn the heaters on and off
- Enable or disable a specific hose or gun
- Turn the pump on and off
- Inputs are activated using a constant 10 to 30 VDC signal voltage, which is supplied by the customer’s control equipment. The inputs are not polarity-sensitive.
To set up an input
- Set up the parameter control option for each input that you connected to the melter. Table 3‐8 lists the available control options. Refer to Setting Up the Melter earlier in this section for information about how to select operating parameters and edit parameter control options
