Further, make sure that only authorized personnel are in charge of operation.

3．Operating Principles
The chute installed on the upper vibrator is connected to the lower vibrator by means of the leaf spring provided
at certain angle, and they are vibrated with a magnet, so that works on the chute are thrown upward aslant,
resulting in little-by-little advancement of the works.
Large vibration can be generated with small oscillating force, since resonance is made to the suction frequencyof the magnet with strength of the leaf spring set properly to the chute mass.

6．Transportation and Installation
CAUTIONThe body is a heavy material. Transport the bodycarefully with care not to cause drop.
（1） Transportation
Do not transport the body while holding the chute. The chute or leaf spring may be deformed.
Make it a rule to hold the base or mount.

□ Note in transporting
This machine is a heavy material. Watch out for dropping in transporting and be cautious enough.
Especially, S20 and S30 must not be carried by single person. They must be carried carefully bymore than one personnel or by use of lifting apparatus or hoisting attachment with sufficient lifting
capacity.
＊Refer to item 10 Specification for the mass of the body (adding the mass of chute if attached).

（2） Installation
Fix the base with bolt securely.
Little vibration will be felt when the base is touched in operation, if the machine is installed
properly.
□ Caution for installation① Be sure to wear safety gloves to prevent the sharp edges of the chute and others from touching
bare hand.
② Do not operate the machine on a base with insufficient strength or in an unstable place.
③ Do not allow the vibrating part of the machine (except the base) to be in contact with someother things in fixing.
④ When the machine is inclined in installation, specified capability cannot be obtained. Be sure
to level the machine.
⑤ When perform welding work or grinding work nearby the linear feeder, protect the linear
feeder all over with a protective cover. Incompliance may deteriorate the performance because

(1) Detach the transporting fixture for chute and linear feeder if any.
(2) Connect power supply. (See the operation manual of the controller for connection in detail.)(3) Turn the speed adjusting knob of the controller counterclockwise to set the graduation at "0".
(Make sure that the linear feeder is free and in no contact with something around.)(4) Turn on the power switch of the controller. (Confirm lighting of LED on the operation panel.)(5) Turn the speed adjusting knob of the controller slowly clockwise to set the graduation at a workpiece
speed that matches with supply capacity. Operate this machine under the maximum acceptable
amplitude of leaf spring in the item 8 in order to prevent breakage of leaf spring.
(Note 1) When the machine is incorporated to some apparatus, do not open or close the primary side of thecontroller but use external control input terminal in turning on and off.
(Note 2) Power connecting work must be performed by personnel in charge of electric engineering. When
modifying or changing connection, see the operation manual of controller.
(Note 3) When a chute that matches with the shape of specified parts is installed, and indication mark is
found around the controller speed adjusting knob, set the adjusting knob at corresponding positionin use.
(Note 4) As to the cable, use the lead wire attached to the vibrator. When it is intended to extend the cable for yourcompany, ensure that the extension length is 10 m max. Further, ensure separate grounding, using a grounding
wire of 2.5 mm2 min. in size. In addition, conduct the protective continuity test to ensure that the machine isgrounded appropriately.
(Note 5) See the operation manual of controller in use.

8．Inspection and Adjustment（1） Adjustment of counterweight

CautionIf the counterweight should move beyond the specified movable range, the setscrew
may loosen, resulting in dislocation of the counterweight from the mounting area,
followed by falling.

If the parts feeding speed is uneven on the front
and back on the chute, move the counterweightback and forth for adjusting.
(Note) Tighten the counterweight fixing screw
securely. Also make sure that the fixing
position of the counterweight is within
the moving range shown in item 5
Dimension Drawing on page 4 - 5(Dimension of *2).

② Caution in attaching and detaching leaf spring
When attaching and detaching the leaf spring, be sure to complete one unit before moving to
the next unit. Do not loosen all the units at the same time.
a) Set the fitting depth of bolts (Dimension L includes the depth on upper vibrator side)
twice the screw diameter, and change the bolt length when the leaf spring increases ordecreases.
※ Tighten the bolt securely, using the table below for guide of tightening torque.

③ Retightening
Check the leaf spring tap bolt and retighten it after actual operating time of about 40 hours.
When the tightening is normal, there is hardly the additional tightening allowance. But,
consider this requirement as retightening of comfortable fitting of the leaf spring.

-9-

④ Correction of fatigue
When the machine is operated with the speed adjusting volume set to the MAX. Position at
all times, add 1 or 2 pieces of leaf springs to a leaf spring unit in either one place.
When the machine is operated 40 - 100 hours, the spring constant of leaf spring itself isdeteriorated by repeated stress by vibration, which slightly reduces the amplitude,
although the leaf spring mounting bolt is jointed normally.
⑤ Replacement of leaf spring
100% replacement of leaf springs is recommended with the guideline of 1-year operation on
the basis of 8 hours a day.
If amplitude cannot be recovered after correction of set in fatigue described in ④ above,
we recommend that you replace all leaf springs, considering that the end of the life of theleaf spring has been reached.
(Note) When a leaf spring is needed newly, purchase one referring to the leaf spring productnumber in 10. Specifications.

（3） Check and adjustment of magnet clearance
Clearance between the magnet and moving iron core is set to those described in the table below
in shipment of the machine from NTN. It is recommended to make is as small as possible to theextent where they are not in contact in the maximum amplitude, therefore check it from time totime and maintain an appropriate value.
<Adjusting procedure>① Remove the cover. (Allowed only on single side)②Loosen the moving iron core tightening bolt.
③Insert a clearance gauge of the specified dimensions for each body (shown in the follwing table)
into the magnet clearance, push the moving iron core toward the magnet side, and temporarily
tighten the moving iron core locking bolt.
④Tighten the moving iron core locking bolt. At that time, take care so that the moving iron core
position set in the Step ② may not deviate.
⑤Pull out the clearance gauge. Check the parallelism to and clearance in the magnet.
⑥ Fit the cover.

Note 1) When the machine is used with the magnet clearance increased by 120% min. of the maximum value
shown in the table, the magnet may burn. Check the magnet clearance from time to time to keep aproper value.
Note 2) When the machine is operated in much dusty atmosphere, such dusts and powders may
stick to the magnet to narrow the clearance, possibly leading to generation of unusual
noise. Conduct periodic check to remove such deposits.
Note 3) No clearance gauge is attached. Purchase a commercial thickness gauge.

（4） Change of power supply frequency
NTN linear feeder is adjusted in conformance to the power supply frequency or controller
setting frequency in the area of use. Therefore when the power supply frequency, which is drive
output frequency, or setting frequency of controller changes, it is impossible to provide normal
vibration. Follow the steps below for changing power supply frequency:(Note) When the drive output frequency is set by variable frequency controller, change of setting is
not required even when power supply frequency is changed (50 Hz and 60 Hz).

Adjustment of leaf
spring(No. of leaf springs)

Example of adjustment

In the case of 18 leaf springs in total of the front and
50 Hz → 60 Hz Increase by about 40% rear, the number of leaf springs is adjusted to about
25.
In the case of 20 leaf springs in total of the front and
60 Hz → 50 Hz Decrease by about 30% rear, the number of leaf springs is adjusted to about
14.
Note 1) For details of switching of the controller power frequency, see the Controller Instruction Manual.
Note 2) When new leaf springs are required, purchase leaf springs while referring to the leaf spring
part No. shown in “10 Specification”.
<Reference: How to check excess and shortage of leaf springs>
When checking whether the leaf springs installed at present
are in excess or shortage for the chute, follow the steps below.
Slightly loosen only one position of leaf spring tightening bolt
during vibration, and check the amplitude.
・Amplitude has increased. → Plate springs are in excess.
・Amplitude has decreased. → Plate springs are in shortage, orappropriate.
It is optimum when sufficient amplitude is provided as well as
amplitude decreases when a bolt is loosened.

9．Troubleshooting
If any trouble should be found, check the following points:(1) No vibration at all
In this case, distinguish the trouble between mechanical system and electric system as shown
below for checking.
Insert an iron piece to the magnet clearance as shown below with power switch turned on.
① When the piece is sucked in strongly
during vibration
Electric system is normal. Therefore,
either the setting of leaf spring number onlinear feeder has a problem, or thedesignation of frequency is wrong.
