## Abstract

A hot melt adhesive system includes a melting unit configured to liquefy a bulk form of hot melt adhesive and deliver the liquefied hot melt adhesive to an application location. The melting unit includes a controller for establishing and/or verifying at least one system condition, such as temperatures associated with system operation. A machine reading unit is coupled with the controller and is capable of receiving information from a machine readable element and communicating the information to the controller for use in establishing and/or verifying the system condition. A method of operating the system includes scanning information on at least one system condition into the controller from a machine readable element, and using the scanned information during operation of the melting unit.

## Claims

### Claim 1

A method of operating a hot melt adhesive dispensing system, the system including a dispensing unit, a controller for managing operation of the adhesive dispensing system, at least one heated hose, and at least one adhesive dispensing module, the method comprising:
receiving information from a machine readable element into the controller, the information for use in establishing various system parameters or conditions and comprising one of:
a) information about the hot melt adhesive, or
b) information about the hot melt adhesive dispensing system; and
the controller performing at least one of establishing or verifying a system operating condition for at least one of the dispensing unit, hose, or dispensing module using the received information.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
monitoring the system operating condition with the controller during operation of the hot melt adhesive dispensing system.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
storing information related to the system condition or the information received from the machine readable element.

### Claim 4 (depends on 1)

The method of claim 1, wherein receiving the information from the machine readable element comprises wirelessly receiving the information from the machine readable element.

### Claim 5 (depends on 1)

The method of claim 1, wherein establishing a system operating condition includes establishing a temperature setting of a heater of the dispensing unit for melting adhesive.

### Claim 6 (depends on 1)

The method of claim 1, wherein establishing a system operating condition includes establishing a temperature setting of a heater for heating the adhesive material in at least one of:
a) the at least one heated hose; or
b) the at least one adhesive dispensing module.

### Claim 7 (depends on 1)

The method of claim 1, wherein establishing a system operating condition includes at least one of:
a) setting dispensing cycle parameters; or
b) setting on/off dispensing time delays.
