SECTION 1
GENERAL INFORMATION
1.0 SCOPE
This manual provides a brief description of sorting, installation instructions,
identification and function of parts, operating procedures, and trouble shooting
procedures.
The ScanMasterII is made in a two-view model for sorting products that must be
viewed from both sides. It is also made in a single-view model for sorting
translucent products that only require viewing from one direction.
The two-view model has eight optical assemblies that view the product from the
front, and eight optical assemblies that view the product from the rear. It utilizes
eight Amplifier PCB assemblies, and two backgrounds.
The single view model has only eight optical assemblies that view the product from
the front. It utilizes only four Amplifier PCB assemblies, and one background.
1.1 SAFETY PRECAUTIONS
1.1.1 VOLTAGES
Dangerous voltages are present in the electronics cabinet, lower power enclosure,
and the viewer. Make sure that all power switches are in the OFF position before
doing service in these areas.
1.1.2 ELECTRICAL INTERLOCKS
The window wiper inside the viewing area operates automatically. An electrical
interlock switch located inside the viewing area on the right side of the machine
prevents operation of the feeders and window wiper when the front viewer is
opened. To prevent personal injury or damage to the wiper mechanism, never
attempt to bypass the interlock switch.
1.1.3 PRINTED CIRCUIT CARD REMOVAL
Before removing or installing printed circuit cards, turn all power OFF to prevent
damage to the cards.
1.1.4 DISCONNECTING AND RECONNECTING PLUGS AND CONNECTORS
When any plug or connector is disconnected or reconnected, always ensure that the
power to the circuit is OFF.

Section 1—General Information 1-2
© 2008, Satake USA Inc.
(ALL RIGHTS RESERVED)
WARNING: Do not disconnect the fluorescent lamps with power on the circuit,
as this will permanently damage the regulated power supply (lamp ballast), and
it will have to be replaced. Turn off the power switch on the front panel before
removing the lamps.
1.1.5 COMPRESSED AIR CLEANING
The compressed air used for operating the machine and for cleaning must be clean,
dry, and oil-free. It should also comply with ISO 8573-1 Class 442 for nonfood
applications and with ISO 8573-1 Class 341 for food applications. Always wear
protective goggles when using the air hose to blow off the machine.
1.1.6 REMOVING AND INSTALLING AIR EJECTORS
Before removing an air ejector, blow off the surrounding area to prevent dust or
other material from entering the ejector or air system.
Turn off the air supply using the valve located at the inlet of the Air System and
allow time for the pressure to discharge before removing an ejector.
After the air and power are turned off, unplug the ejector electrical connector by
squeezing the latch release tab, and pulling outward on the connector. Remove the
ejector from the ejector manifold assembly by squeezing the ejector latch release
tabs, and pulling the ejector away from the manifold.
Install the ejector by aligning its inlet and outlet ports with the corresponding ports
on the manifold and pushing in until the latches engage. Install the electrical
connector and push in until its latch engages.
1.2 BRIEF DESCRIPTION OF SORTING (See Figures 1-1 through 1-5)
The ScanMasterII is specially designed for the rapid and accurate sorting of small,
free-flowing, products that require selection to obtain an acceptable product of
uniform hue.
Product to be sorted is continuously supplied to the product input hopper (See
Figures 1-1 through 1-5).
Three vibratory feeders cause the product to flow out of the hopper and into eight
chutes, each of which is divided into channels. The rate of flow is determined by the
amplitude of the feeder vibration and the position of the product flow control gates.
As the product travels down the infeed chute, the particles are accelerated and
separated.
The viewer is illuminated by four fluorescent lamps: two in the front and two in the
rear. The optical assemblies measure the light received from each particle.
When particles of abnormal color are detected, they are diverted from the stream by
a small blast of air from the air ejectors. These unacceptable pieces are collected in
the reject chute.

Acceptable particles continue on their normal path into the accept chutes.
The sample tubes may be pivoted into the accept stream by pushing inward on the
top end of the tubes. By doing this, a sample of the accepted particles from a
particular chute can be collected for evaluation.
A window wiper periodically removes any dust that may have accumulated on the
viewer windows. This ensures consistent sorting results.
1.3 INSTALLATION OF THE ScanMasterII
1.3.1 LOCATION
The ScanMasterII should be installed in a location that is level and free of vibration.
The ambient temperature must be between 32°F and 110°F (0°C and 43°C). Avoid
places where it is humid and hot. Best operation and longer life of components will
be achieved where the temperature is between 70°F and 80°F (21°C and 27°C).
Avoid areas where direct sunlight or light from bright lamps will enter the optical
section.
The machine should be installed in the process line after a precision grader that
removes fines and dust. It should be installed in the line following all processing
operations, where the product has cooled, and is ready to be packaged.
The ScanMasterII weighs approximately 1100 pounds (500kg). The floor or
platform where the machine is located must be strong enough to adequately support
this weight.
The location should provide adequate space for operation, cleaning and
maintenance. Generally, we recommend an absolute minimum of two feet on all
sides of the ScanMasterII. If space constraints are severe, the clearance at the rear
and sides could be reduced slightly, but will make service more difficult. Additional
space in front of the ScanMasterII, up to three or four feet, is desirable. See Figure
1-6 for dimensions of the sorter with the service panels open.
1.3.2 TRANSPORTING THE ScanMasterII
After removing the machine from the crate, it can be moved to the installation site
by attaching a chain or cable to the lifting eyes at the top of the machine frame.
The hoisting angle should be 50 degrees or more as shown in Figure 1-7.
The machine can also be moved by placing the forks of a lift truck under the lower
cross members. Care must be taken to avoid sudden stops that may cause the
machine to tip over.
When moving the machine, care must be taken to not bump the machine against
other objects to avoid damage to control knobs, paint, etc.

When the machine is in place, it must be bolted to the floor or platform using the
anchor feet at the bottom of the frame. Insure that the machine frame is well
grounded to the platform. It may be necessary to grind away a small amount of
paint from the anchor feet and the platform in order to assure good metal-to-metal
contact. Also verify that the platform is grounded to earth with a ground rod or a
connection to a water pipe.
1.3.3 INSTALLING THE FEEDERS AND INPUT HOPPER
The vibratory feeders and input hopper are removed from the ScanMasterII for
shipping.
After the machine has been placed in its operating location, the feeders and hopper
must be re-installed.
When viewed from the rear of the machine the larger feeders are installed on the
right-hand side and the smaller feeder is installed on the left-hand side. Install each
feeder so that its base feet are located inside of the holes in the feeder plates (See
Figures 1-1 and 1-3). Be certain that the feeders match the serial number and
position indicated on the feeder tags.
The position of the feeders was adjusted at the factory so that the trays are centered
within their respective chute. The front end of each tray extends forward about 3/8
of an inch from the back outside edge of the top of the chute. Check feeder position
during operation. Generally, feeders should be located as far to the rear as possible
without spilling product at the back of the chute. This will insure minimum product
drop from the feeder to the chute.
Plug each feeder into its respective receptacle.
After the feeders are installed, the input hopper should be installed with the
product level sensors facing the front of the machine (See Figure 1-1).
The sensors are numbered 1,2 and 3 from left to right (as viewed from the front of
the sorter). The mating connectors are located on the inward side of the right-hand
frame member, and are numbered 1,2 and 3 from rear to front. The sensor
connectors should be plugged into their respective mating connector located on the
inward side of the right-hand frame member.
In some applications an additional level sensor (surge sensor) may be supplied. The
mating connector for this sensor is located below the connector for hopper sensor
number 1. This sensor should be mounted in the surge hopper above the smaller
feeder. When the product level falls below the hopper sensor, the feeder below it
will stop. When the product level rises above this sensor the feeder will restart. If
the surge sensor is present, the feeder will not restart until the product level rises
above the surge sensor. This feeder control strategy will minimize the number of
stop/start cycles and maximize the length of each ON cycle.
The input hopper must be positioned so that its outlet necks are centered, left to
right, in the feeder trays. The rear of each neck should be about 1/4 to 3/8 inch
forward of the back of the feeder tray. The necks of the hopper must not touch the

Section 1—General Information 1-12
© 2008, Satake USA Inc.
(ALL RIGHTS RESERVED)
feeder trays during operation, but should be positioned low in the feeder. If
necessary, lower the hopper level adjustment so that the bottom of the outlet necks
is no more than 1/2 inch above the bottom of the feeder pan.
The feed system must be thoroughly grounded to prevent static electricity buildup
in the product. Plastic tubes or chutes should never be used, as they greatly
increase the level of static electricity generated in the product.
1.3.4 CONNECTING THE POWER
The ScanMasterII is connected internally at the factory to operate at 105-125 V.A.C.,
50-60 cycle, 1 phase when it will be operated in a country that uses this voltage.
The machine is connected internally at the factory to operate at 210-250 V.A.C., 50-
60 cycle, 1 phase when it will be operated in a country that uses that voltage. Make
certain that the machine is properly connected to operate on the voltage that you
will be using.
The ScanMasterII uses high quality regulated power supplies for the electronics and
rugged power transformers for the lamp and ejectors. However, as for any
sophisticated electronics application, in areas where the line power is not stable, we
recommend a regulating type transformer installed in close proximity to the
machine.
The machine is equipped with a power cord that can be used, provided local
electrical codes permit its use. If the cord is used to plug into a receptacle, a plug to
match the receptacle must be installed on the end of the cord. The cord is
connected at the factory as shown in Figures 2-1 and 1-8.
If the power cord will not be used, connect power directly to the power lockout
switch in the lower power enclosure, and connect incoming power ground to the line
filter, also found in the lower power enclosure (See Figures 2-1 and 1-8).
Make certain that an EARTH GROUND is connected to the grounding point below
terminal block TB1 on the lower power supply assembly as shown.
1.3.5 CONNECTING THE COMPRESSED AIR
The compressed air used for operating the machine and for cleaning must be clean,
dry, and oil-free. It should also comply with ISO 8573-1 Class 442 for nonfood
applications and with ISO 8573-1 Class 341 for food applications. A refrigerated
dryer is recommended.
The pressure of the compressed air supplied to the machine must be a minimum of
90 psi at the machine to allow for pressure drops across the air filters, etc.
The air line to the machine must be 3/4 inch pipe or larger. If the compressor is
more than 50 feet from the machine, 1inch or 1 1/4 inch pipe should be used.
Before connecting the air line to the machine, it must be blown out to remove any
shavings or other foreign material.
The regulator on the machine should be set to 40 psi during normal sorting
operation. If the machine is being used to resort defective material from another

Section 1—General Information 1-13
© 2008, Satake USA Inc.
(ALL RIGHTS RESERVED)
machine or if the product being sorted contains a high percentage of defects, the
regulator should be set to 45 psi while the machine is operating.
1.3.6 DUST EXTRACTION
Two 4 inch outside diameter dust removal outlets are provided on the rear side of
the ScanMasterII just above the lower power supply enclosure (See Figure 1-3).
These outlets should be connected to an exhaust system to remove dust from the
viewing area. An air flow rate of 530 cubic feet per minute is recommended.
This will reduce the amount of manual cleaning required and provide more
consistent and efficient operation of the machine.
1.3.7 OTHER CONSIDERATIONS AND PRECAUTIONS
DO NOT WELD DIRECTLY TO THE MACHINE. Further, when welding or painting
around the machine, be sure to cover it. Special attention should be paid to avoid
cuttings, welding splatter or paint on the chutes.
Any hopper installed above the input hopper on the machine must not touch the
machine. If the hopper does touch the machine, it can transfer vibrations to the
machine that will cause the product to flow through the feeders, even if the feeders
are turned off. The vibration can also have other adverse effects.
A product cut-off gate must be installed between the plant input hopper above the
machine and the machine input hopper. This will permit the machine hopper to be
emptied for service if required.
Take-away chutes or conveyors also should not be directly connected to the
machine.
The take-away system should have provisions to take samples of both accepts from
each individual chute and rejects from each machine. This will enable the operator
to determine each machine’s performance and adjust it for highest efficiency and
best reject concentration.
