Melter Pneumatic Flow Control
See Figures 6-2 and 6-3.
ProBlue Flex mel ters come with four different pressure control options:
S P1 – Manual Pressure Adjustment with Analog gauge pressure
readout
This pressure control option allows the user to manually adjust the
system to the desired set point, with a 4 mm hex key. The pressure is
then displayed to the user by means of an analog gauge adjacent to the
adjustment feature.
S P2 – Manual Pressure Adjustment with Digital pressure readout
This pressure control option allows the user to manually adjust the
system to the desired set point, with a 4 mm hex key. The pressure is
then displayed digitally on the melter's OLED display, or on the remote
touchscreen user interface for OEM interface units.
S P3 – Remote Pressure Adjustment with Digital pressure readout
This pressure control option allows the user to locally or remotely adjust
the system to the desired set point.
- For local adjustment, the pressure is set via the OLED interface
- For remote adjustment, the pressure is set via the customer’s
PLC or web server.
Once set, the pressure can be password protected to prevent
un-intended adjustment. The pressure is then displayed digitally on the
melter's OLED display, or on the remote touchscreen user interface for
OEM interface units.
S P4 – Remote Pressure Adjustment with Digital pressure readout,
and run-up control
This pressure control option allows the user to locally or remotely adjust
the system to the desired set point.
- For local adjustment, the pressure is set via the OLED interface.
- For remote adjustment, the pressure cs set via the customer’s
PLC or web server.
Once set, the pressure can then also be password prote cted, to prevent
un-intended adjustment. The pressure is then displayed digitally on the
melter's OLED display, or on the remote touchscreen user interface for OEM
interface units.
The run up control associated with this pressure option also allows for
pressure adjustment by means of the control system, as derived accordingly
from the line speed input.
