High-Pressure Fluids
High-pressure fluids, unless they are safely contained, are extremely
hazardous. Always relieve fluid pressure before adjusting or servicing high
pressure equipment. A jet of high-pressure fluid can cut like a knife and
cause serious bodily injury, amputation, or death. Fluids penetrating the
skin can also cause toxic poisoning.
If you suffer a fluid injection injury, seek medical care immediately. If
possible, provide a copy of the MSDS for the injected fluid to the health care
provider.
The National Spray Equipment Manufacturers Association has created a
wallet card that you should carry when you are operating high-pressure
spray equipment. These cards are supplied with your equipment. The
following is the text of this card:
WARNING: Any injury caused by high pressure liquid can be serious. If
you are injured or even suspect an injury:
SGo to an emergency room immediately.
STell the doctor that you suspect an injection injury.
SShow him this card
STell him what kind of material you were spraying
MEDICAL ALERT—AIRLESS SPRAY WOUNDS: NOTE TO PHYSICIAN
Injection in the skin is a serious traumatic injury. It is important to treat the
injury surgically as soon as possible. Do not delay treatment to research
toxicity. Toxicity is a concern with some exotic coatings injected directly into
the bloodstream.
Consultation with a plastic surgeon or a reconstructive hand surgeon may
be advisable.
The seriousness of the wound depends on where the injury is on the body,
whether the substance hit something on its way in and deflected causing
more damage, and many other variables including skin microflora residing
in the paint or gun which are blasted into the wound. If the injected paint
contains acrylic latex and titanium dioxide that damage the tissue’s
resistance to infection, bacterial growth will flourish. The treatment that
doctors recommend for an injection injury to the hand includes immediate
decompression of the closed vascular compartments of the hand to release
the underlying tissue distended by the injected paint, judicious wound
debridement, and immediate antibiotic treatment.

Description
The ISC2 Series induction systems provide simple, efficient, and uniform
drying of side seam coatings and bottom spray coatings. The systems use
solid state induction heating to generate heat within the can body, drying the
coatings at various line speeds dependent on quantity of coil tray units. Coil
trays can be mounted in any position for maximum versatility.
1 M ISC2 Coil Tray
Power Supply
Operator Control Pedestal
Figure 1 ISC2 Series Induction Dryer
Features
Instant on/off When the line starts, heating within the can body starts instantly. Since heat is
created directly within the can surface, there is no thermal inertia. When the
line stops, heating instantly stops or continues per the preset time.
Energy savings Solid state induction heating is extremely efficient. Most of the power
consumed is directly realized as heat in the can body. When the line stops,
almost no power is consumed.
Reliability The solid state design of the dryers minimizes downtime. Fewer moving parts
equals less wear items.
Small footprint Due to the high efficiency of induction drying, the dryer is much smaller than a
conventional oven.
Temperature monitor An infrared sensor, located on the last coil tray, determines the temperature of
the can body. The temperature is displayed on the operator terminal.

Part 1606739-01 E2014 Nordson Corporation
Theory of Operation
The induction coil is connected to the power supply, and the can bodies
travel below or above the coil. When the power supply applies an
alternating current, the coil generates an alternating magnetic field that cuts
through the side seam or dome of the can bodies dependent on the
application. This results in large eddy currents circulating within the can
bodies. The resistance to this circulating current results in heat that cures
the applied coating. In steel cans, there is also heat from magnetic
hysteresis. Careful coil and power supply design ensure close control of
heating rates and uniformity.
Power to the induction coils and distance between the coils and the can
bodies is adjusted during setup to provide the desired temperature of can
bodies exiting the induction dryer. In some cases, an infrared temperature
sensor can be used to provide over or under temperature safety shutdowns.
Accuracy of infrared sensing depends on matching the emissivity of the
product to the sensor.
A laser motion sensor is mounted at the front of the unit to constantly
monitor line movement. If the line stops, power to the induction coil is
stopped. When the line restarts, the inverter is immediately restarted.
WARNING: Never disarm any diagnostic or interlock devices including but
not limited to the following:
SCurrent sensor
SOver temperature switches
SAir pressure switches
SPower supply door safety switches
Disarming these devices will void the warranty and may cause personal
harm or equipment failure.

External Interlock
The external interlock is an optional connection that indicates to the dryer
that the production line is running. When the interlock is used, the dryer
controller will not apply power to the induction coil if there is no interlock
signal.
CAUTION: Nordson engineering recommends that the external interlock be
connected and enabled. Without the interlock, a random trip of the line
motion sensor may cause the controller to apply power to the coil while the
line is stopped, which could overheat stationary can bodies near the coil.
Connecting the External Interlock
The external interlock requires an external 24 Vdc source at 100 mA to
power an internal relay coil (refer to Note below). The external 24 Vdc
power source is not referenced to the dryer ground. The interlock indicates
to the dryer system that the production line is running. Without this signal,
the controller will not apply power to the induction coil.
NOTE: The interlock relay coil is relay CR4 (IDEC part number RY22S).
Additional relay voltages are available through an IDEC distributor.
1. Locate the interlock terminal behind the control enclosure doors, in front
of the control panel on the right side.
2. See Figure 6. Drill a hole or use a knockout tool to bring the interlock
cable into the enclosure. Install a properly sized strain relief or conduit
connector in the knockout.
3. Connect the interlock wiring to the terminal TB31-T and TB32-B.

Disabling the External Interlock
If the external interlock will not be used, set the ISC2 system to run with the
signal from the motion sensor only.
1. Use the touch screen to go to the Navigation screen.
2. Select Options to go to the Options Setup screen.
3. Select the External Run Signal button to toggle it to Ignored.
Optional Status Contact
See Figure 6. The status contact provides a Dryer Ready signal. It is used
in conjunction with the customer interlock. The contact indicates when the
dryer is off or in a fault condition. The contact is off when:
SThe dryer is turned off.
SAny fault on the operator control is activated.
Status contact connection: Terminal 32 output contact (output)
Motion Sensor
See Figure 7. The motion sensor requires field mounting and should be
located close to the entry end of the coil tray (coil tray number 1 for systems
with multiple trays.) On lines with conveyor speed greater than 15 m/minute
(50 ft/minute) the motion sensor should be positioned up stream to ensure
the coil tray is on prior to a can body entering the induction field.
Adjust the motion sensor sensitivity as described on page 22.
