Connecting Compressed Air
Connect dry, clean and non-lubricated compressed air to the compressed air
connection (1). Dirt particles in the air may not exceed 30 m in size.
Air pressure
Min 3 bar 0.3 MPa 43.5 psi
Max 8 bar 0.8 MPa 116 psi
NOTE: A pressure restrictor valve behind the compressed air connection
limits the air pressure to 8 bar / 0.8 MPa / 116 psi
Pneumatic Plate
Also refer to pneumatics diagram.
Pressure Control Valves
CAUTION: Do not change the setting:
S
Raise pneumatic cylinder (2).
NOTE: Default pressure is 1.6 Bar / 0.16 Mpa / 23.2 PSI
S
Aerate container (3):
NOTES:
S
Default pressure is 1 Bar / 0.1 Mpa / 14.5 PSI
S
A lower pressure makes it difficult to raise the platen.

Adapting the Bulk Melter to the Container Used
Platen Position: Adjusting Switches
WARNING: Risk of squash! Make sure that switch 1 is not actuated until the
platen is inside the container.
A switch rod activates the two switches (1 and 2) one after the other,
triggering the following switching functions:
S
Switching functions when lowering:
S
Switches from two-hand lowering mode to normal lowering mode
when the platen sealing ring is completely submerged in the container
(switch 1)
S
Activates the Container empty indication (switch 2).
S
Switching functions when raising:
S
Switches off container aeration (switch 1).

Installing Inputs and Outputs
The inputs and outputs are used to exchange data with the customer's
production equipment and control hardware such as a PLC.
1. A female quick connector (24 positions + PE) is located on the melter
side panel. Route a signal cable from the control equipment to the melter
through a male quick connector (24 positions + PE). The male quick
connector has a M25 strain relief to fasten the signal cable. I/O connector
designation: -10X21 Function: transmits the digital input/output signals
and gear-to-line signal between the parent machine and the Nordson
melter provide 24VDC from internal melter.
NOTE: Use a signal cable suitable for NEC class1 remote control and
signaling circuits. To reduce the possibility of electrical shorting, route the
cable so that it does not touch nearby circuit boards.
2. Connect each pair of input and output wires to the appropriate terminals
on I/O connector. Refer to table below for the terminal numbers that
correspond to each input.

Connecting Line Speed Voltage
To use automatic mode, a signal generator, such as an encoder, must be
provided by the customer and installed to measure the production line speed.
The pump controller accepts an analog 0-10 V
DC
input signal. Connect to
coupler component -190U1; make sure the polarity is correct - refer to wiring
diagram.
