Setting Up Inputs/Outputs
DuraBlue II adhesive 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 the standby mode
Turn the heaters on and off
Enable or disable a specific hose or applicator
Enable the motor
The input contacts use a constant 10 to 30 VDC signal voltage. The inputs
are not polarity sensitive.
WARNING! The operator can override the melter inputs by using the control
panel function keys. Ensure that the control logic for any external device that
sends an input signal to the melter is programmed to prevent the creation of
an unsafe condition in the event that the operator overrides an external input
to the melter.
The melter is also equipped with three user‐configurable outputs. Outputs
are used to communicate with user‐supplied production equipment or control
hardware, such as a programmable logic controller.
Each output is customer‐wired and then set up in the melter's firmware to
provide one of the following outputs:
The melter is ready
The melter is ready and the motor is enabled
A fault has occurred
The hot melt level is low (only if the optional level switch is installed)
The service LED is on
All outputs contacts are rated at 240 VAC 2 A or 30 VDC 2 A. All contacts are
normally open when the melter is turned off.
