Procedure
Thermocouple
Check the thermocouple for wear and good contact with the can ends. Clean
the thermocouple with a soft brush. Remove any debris lodged between the
element and the mounting pocket. Replace the thermocouple as needed.
Motion Sensor
Clean the sensor head lens with a clean, soft cloth. When the system is not
being used, cover the lens with the attached cover.
Cooling Blower Filter
Inspect the blower filter for dust or obstructions. Replace the filter as needed.
If the air flow is reduced, the system electronics can overheat. End drying
may also be affected by reduced air flow.
Coil Tray
Periodically inspect the glass coil tube for cleanliness and integrity. Clean the
tube with common solvents. Do not to get any solvent on the nylon hubs at
the dryer entrance or exit. Some solvents may also have an adverse effect on
the dryer’s exterior finish.
If the glass tube is cracked, only replace it with a new tube supplied by
Nordson. Different sizes and wall thicknesses are used depending on the can
end size and the application.
