Part 1128350_02
User Interface(s)
The system supports three kinds of user interface. The system can be
configured at purchase as well as changed in the field.
The OLED HMI features a display that can display 4 lines of text. This
S
interface is located on the E-Box door.
For details on the OLED user interface, refer to the ProBlue Flex
Adhesive Melter Using the OLED User Interface (P/N 1128351).
The Original Equipment Manufacturer (OEM) user interface has
S
discrete LEDs and buttons but no display. It is intended to be used
when the primary interface and control of the melter is by
communications to a Programmable Logic Control (PLC). This
interface is also located on the E-Box door
For details on the OEM user interface, refer to the ProBlue Flex OEM
Users' Guide (P/N 1129255).
There is a color LCD (Liquid Crystal Display) touchscreen. It connects
S
to the LVC by Ethernet and can be located remotely.
Adhesive Level Sensor
The capacitive level sensor is located on the wall of the melt section (tank or
MOD). It is connected via a triaxial cable to the LVC. The adhesive level is an
analog value continuously available to the user for monitoring and can be
used to refill the unit.
Optional Functional Blocks
Air pressure sensor is a small board located above the E-Box in the
pneumatic enclosure. It senses air pressure before the pump solenoid and
enables this to be read electronically with high accuracy and displayed or
transmitted via factory communications (if installed).
Legacy I/O is a daughter card that attaches to the LVC to provide 4 isolated
inputs and 3 relay outputs in the same format as a ProBlue melter. It has
identical circuitry and pinouts to the legacy melter to support easy upgrade
from Nordson's Blue Series melters to the ProBlue Flex melters. The control
for the I/O is through the LVC; this board has no controller.
Adhesive Tracking System (ATS) is a daughter card that attaches to the
LVC to provide adhesive tracking functionality similar to Nordson's ProBlue
ATS. This board is an intelligent subsystem that operates in parallel with the
LVC but under its control. It is connected the LVC via Ethernet in order to
support the higher data bandwidths needed.
