3．Operating Principles• NTN separately placed hopper mainly consists of a tank to store works (specified parts), chuteset in the lower area of the tank, rubber vibration insulators and support members to
support them.
•Works charged in the tank are received by the chute. When the magnet is turned ON, thechute vibrates to discharge the works. Discharge of works is controlled with the work
volume in the bowl feeder bowl detected by the level switch. The magnet is turned
ON-OFF by the controller.

※2 In case of not using the level switch, please short circuit between S2-S3 terminals of the controller,
with short circuit clamp etc.

6(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 it is intended to combine the separately placed hopper with the NTN bowl feeder, ensure anelectric circuit so that the separately placed hopper also stops when the bowl feeder and others
stop. For details, refer to the Controller Instruction Manuals.
(Note 4) The supplied level switch① The supplied level switch is a hopper discharge control equipment to detect the work volume levelin the bowl feeder bowl and others to keep the work volume constant. With a microswitch built in,
the level switch is so designed that the contact closes (ON) when the detection lever is in the rightdownward direction (no works) and opens (OFF) when the detection lever comes afloat as a resultof detection works. To quantity of the work to spend, please use it as Hopper driving control(ON-OFF) equipment by adjusting the height of the level switch detection lever.
② Structurally, the level switch does not function when the bowl feeder is in stop. Incorporate an
appropriate interlock circuit so that the hopper may not run during shutdown of the bowl feeder.
③ Use the detection lever after adjusting its setting position in the horizontal and height directions asneeded for detection of specified parts.

(2) Charge works in the tank. (Strictly observe instruction of an appropriate work storage quantity
specified by NTN, if any.)(3) Turn the controller speed control volume CCW to adjust the volume to the scale “0”. (Make sure thatthe separately placed hopper is free and in no contact with something around.)(4) Turn ON the POWER switch of the controller. (Make sure of lighting of the POWER lamp.)(5) Slowly turn the speed control volume CW to adjust the volume to the position of an necessarydischarge quantity. Operate this machine under the maximum acceptable amplitude of leaf spring in
the item 8 in order to prevent breakage of leaf spring. (Indication mark is found around the controller
speed adjusting knob, set the adjusting knob at corresponding position in use.)(6) Operate the detection lever to check that separately placed hopper is turned ON-OFF.
(Note) To stop discharge of products from the separately placed hopper temporarily or settle theproblem of troublesome operation of the hopper during adjustment, bring up the detection lever,and pass pin of f4 max. through the run-through hole in the cover to lock the lever.

78. Inspection and Adjustment(1) Acceptable maximum amplitude of leaf spring
Operate the machine with the amplitude below that shownin the following table in order to prevent breakage of leaf
spring. If the machine is used with greater amplitude, theleaf spring may be broken earlier. When measuring theamplitude, affix the attached amplitude mark as shown
below, and be sure to sum up the reading of upper andlower amplitude mark.

② Insert a clearance gauge of the specified dimensions for each body (shown in the above table) into themagnet clearance, push the movable iron core toward the magnet side, and temporarily tighten the
movable iron core locking bolt.
③ Tighten the movable iron core locking bolt. At that time, take care so that the movable iron core
position set in the Step ② may not deviate.
④ Pull out the clearance gauge. Check the parallelism to and clearance in the magnet. Check that no
deviation is present in the clearance between the magnet and the movable iron core.

⑤ Fit the cover. (Allowed only on V72)
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 fromtime to time to keep a proper value.
Note 2) When the machine is operated in much dusty atmosphere, such dusts andpowders 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.

(3) Bolt tightening check① The bolt which fixes a leaf spring (please refer toa right figure for V01 - V12. There is V72 in a
vibrator) are tightened by us sufficiently before
shipping. But, to prevent a possible trouble due toloosening of them, periodically check that they are
not loosened. In addition, please use things morethan strength classification 10.9 when I change abolt. (Leaf spring clamping torque and thestrength classification refer to specifications ofClause 10.)
② By vibration such as the part injection, a tankfixation volt might be loosened. Same as
described above, periodically check that the tankfixation bolts are tightened securely, and pleasechange it as needed.

Bolt which fixes a leaf spring

9. Troubleshooting
If a machine trouble should take place, check the following points.
(1) No vibration at all① Improper connection of power supply (See the "Wiring and Running Methods" in Section 7. )② Fusion of controller fuse
③ Disconnection of magnet coil
④ Wrong operation or break of microswitch(2) Vibration available but amplitude insufficient① Improper power supply (such as connection of 100 V in spite of 200 V specifications)② Loosening of leaf spring fixation bolt
(For leaf spring fixation torque, see the specification table to item 10.)
③ Loosening of fixation bolts of frame and others④ Excessively large work charge mass
(3) Unavailability of control of vibrations① Controller in trouble(4) Unusual metallic noise① Excessively narrow magnet clearance or inclusion of foreign matter③ Excessive amplitude③ Loosening of clamping bolts of the tank and the vibrating unit
When you inform NTN of trouble condition with unknown cause, let them know the detail as far as
possible with reference to the above so that they can take a measure as soon as possible.
