Retrofitting First Pressure Sensor (Electrical)
Melters with pressure sensors have a shielding plate for the CAN bus on the
motor controller If the pressure sensor is added, the shielding plate also has
to be added.
NOTE: If there are two pressure sensors, ensure that they are positioned
correctly (Refer to the numbers in the manifold). When the first pressure
sensor has been connected, set it up on the control panel. Then connect the
second one.
1. Use two screws (1) to fasten the shielding plate (3) to the last motor
controller.
2. Carefully insulate the pressure sensor line (CAN bus). The "red" and
"black" lines should be positioned similarly to the illustration.
“red,” “black,” “bare,” “blue,” “white”: These designations correspond to
wiring diagram page SYS.
3. Then remove only the sheath from the pressure sensor line to expose the
braided screen (approx. 20 mm / 0.8 inch).
4. Fold over the braided screen so that it overlaps the sheath. This
increases the diameter of the pressure sensor line somewhat, so it rests
more firmly in the clamp.
5. Use a screw (2) to fasten the clamp (4) to the shielding plate. The braided
screen of the pressure sensor line must be inside of the clamp.
6. Use cable ties (Fig. 7‐12) to fasten the pressure sensor line to the
shielding plate.
Replacing Pressure Sensor
Refer to section Maintenance / Pressure Sensor for information on inserting
and extracting the pressure sensor.
Information on T-tap and CAN Bus Cables with Hexagon Nut
Fig. 7‐13: Tighten the hexagon nut with 0.6 Nm torque. Nordson
recommends the torque wrench made by Murr Elektronik, Murr article
number 7000-99102-0000000.
The last pressure sensor along the bus must be equipped with a terminating
resistor (120 ).
