Modes of Operation

DuraBlue II adhesive melters operate in the following modes.

Automatic Scan (Normal Mode)

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 the automatic scan

mode unless it is placed into another operating mode.

Standby

The temperatures of the tank, hoses, and guns are reduced down 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.

Gear‐to‐Line Capability

The melter is capable of delivering an adhesive output that is geared to the

production line speed. The gear‐to‐line capability is enabled or disabled

through the motor control system. A line‐speed signal generator must be

installed if you want to use the gear‐to‐line capability.

NOTE: The gear‐to‐line mode of operation is also known as automatic mode

or key‐to‐line mode.
