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.
