2. DELIVERYANDMOUNTINGINSTRUCTIONS
The TCB is normally delivered pre-mounted and pre-wired with the Afterfilter. In case the TCB is
shipped loose with the unit, follow the next steps to ensure a faultless functioning of the control box.
When the Control Board is received, verify that the enclosure has not been damaged during
shipment. Compare the items received against the packing list. If you find any components that
are damaged or missing, notify the delivery company and your local Nordson representative.
Unpack the Control Board enclosure. Some items may have been shipped inside the enclosure.
Remove any packing material and dispose of it properly.
Items shipped loose with the Control Board may include:
Slave Solenoid valve enclosures
safety filter
wiring diagram
installation and operation manual
spare fuses
2.1. Enclosure location
The enclosure of the Control Board should be mounted in a location convenient for the operator or
maintenance personnel. Since the display provides visual warning of problems and operating
conditions, much of its value is lost if the location does not permit continuous observation. For the
longest, most trouble-free operation, mount the enclosure on the unit or a wall/column with little or no
vibration.
The distance away from the Afterfilter is limited by the length of tubing and cable supplied with the
equipment (standard 10 m).
In order to get reliable signals to the sensors, the Control Board’s pneumatic sensor lines should not
exceed 20 m. Lengths in excess of this may weaken the signals to the point that they are not reliable.
Contact your Nordson representative for assistance if the sensor lines must be longer than 20 m.
If the area in which the controller is to be located is defined as a hazardous area check to ensure the
rating of the controller supplied is suitable for this area.
2.2. Pneumatic installation
The Afterfilter has tubing fittings installed in the clean air plenum and the dirty air plenum. Attach one
tube from the clean air plenum to the low pressure fitting on the enclosure (blue connector). Attach the
other tube from the dirty air plenum to the high-pressure fitting (black connector). All connections need
to be airtight.
To avoid ingress of powder into the controller pressure transducer, it is recommended that an
in-line filter is fitted between the dirty side of the collector and the controller connection. For
collectors handling explosive powders this filter must be used in both the clean and dirty side
connections.
