INSTALLATION AND OPERATING INSTRUCTIONS

FOR METALFAB POSIBINS

Description

The Metalfab Posibins are an assembly of a Bin Activator and a stationary bin. The
bins are either equipped with leg supports or knee brackets for mounting to the
customerÅfs steel work.

Installation

After the unit is removed from the skid and put in place, it should be leveled and
securely bolted using the holes provided in the leg brackets or knee brackets.

The vibrator should be wired (see the wiring diagram in the conduit box or the
manufacturers instruction sheet) using a flexible cord. Neoprene covered braided wire
is suggested. The vibrator can run either clockwise or counterclockwise.

All connections to the Bin Activator must be flexible. It is good practice to make
connections to the bin section also flexible.

After installing the Posibin and tightening all bolts, run the unit empty for approximately
ten minutes. Then recheck the suspension arm bolts, vibrator mounting bolts and
sleeve clamps for tightness.

Note: When tightening the clamps, be sure to support the far side tube

with vise grip pliers when turning nut. Failure to do so may
cause a twisting action on strapping which may lead to damage
of clamp.

Suspension arm bolts for the 3 foot diameter and larger units must be torqued to 540
foot pounds. Vibrator mounting bolts as follows:

3 / 8Åh BOLT...........................................35 FOOT POUNDS

1 / 2 BOLT.............................................125 FOOT POUNDS

5 / 8Åh BOLT.........................................160 FOOT POUNDS

3 / 4Åh BOLT.........................................310 FOOT POUNDS

1Åh BOLT...............................................540 FOOT POUNDS

Vibrator Installation

1. This unit imparts vibration to the Bin Activator. It must be securely bolted to the
unit (torque mounting bolts according to previous instructions). All bolts must be
retightened after the first ten minutes of operation and again during the second
day of operation. All nuts and bolts, especially vibrator mounting bolts, should

be retightened every three months or more frequently, depending on the amount
of usage.

2. Because the Bin Activator, including the motor, vibrate, the electrical connections
must be made with flexible lead. Braided Neoprene covered cable is
recommended.

WHEN INQUIRING ABOUT ANY POSIBIN, ALWAYS REFER TO THE SERIAL
NUMBER STAMPED ON THE METALFAB NAMEPLATE.

Operation

VIBRATOR FORCE ADJUSTMENT:

WARNING! Before any adjustments,

vibrator should be electrically ÅeLOCKED OUTÅh.

1. The centrifugal force setting of the vibrator is set at the factory for the minimum
force level that will produce flow of product. If flow is not instantaneous or
continuous, it may be necessary to increase the centrifugal force. To do so, the
following procedure should be followed:

1) Remove the bolts of both the upper and lower end covers.

2) Remove end covers exposing the four (4) eccentric weights.

Note: The (2) OUTER weights on the

INVICTA

Explosion Proof and the

METALFAB

TENV vibrators are the weights to be adjusted. The

two (2) INNER weights on the

INVICTA

TENV vibrators are the

weights to be adjusted.

2. To increase the force setting, loosen the clamping bolt on the two (2) weights
that will be adjusted. (See note above).

3. Refer to the applicable vibrator operation and maintenance instruction for force
settings and technical information.

4. As the centerline of the adjusted weights approach the centerline of the fixed
weights, the centrifugal force is increased. When the weights centerline are
opposed, the centrifugal force decreases. If the centerline of all four (4) weights
are completely aligned, you will develop the maximum force available for that
size vibrator.

5. Regardless of which vibrator you have, when you have completed your force
adjustment, the OUTER weights should be in line with each other and the INNER
weights should be in line with each other. ANY OTHER ARRANGEMENT WILL
RESULT IN A MOTION THAT CAN DAMAGE THE VIBRATOR AND BE VERY
DETRIMENTAL TO THE APPLICATION, WELDS OF THE BIN ACTIVATOR AND
SUPPORT STRUCTURES.

6. Assemble the unit by reversing the procedure outline as above.

Note: Bin Activator vibrator should be electronically interlocked with

down stream feed devices, i.e., when screw, belt, rotary, etc.
feeder stops _ vibrator should also stop.

Full Load & Starting Currents

See Vibrator Instruction Manual and Motor Nameplate Data.

Secondary Baffle

1. The secondary baffle has been positioned by Metalfab engineering for your
application requirement. ItÅfs position will allow for the proper flow of product
through the Bin Activator outlet.

2. The position of the secondary baffle is maintained by an Esna type lock nut. The
secondary baffle can be repositioned vertically by using a deep socket type
wrench to loosen the lock nut, thereby allowing the secondary baffle to be
turned, possible by hand, on the threaded section of the extended rod, to a
higher or lower position. Since the secondary baffle is located near the outlet, it
is easily accessible from the outlet.

3. If flow problems occur, the secondary baffle could be repositioned to help
eliminate the problem. Before making any adjustments, it is advisable to check
with Metalfab engineering for advice as to what new position might be helpful.

Maintenance Instructions

1. Vibrator Lubrication

The vibrators are lubricated as supplied. The lubrication is good for 2,000 to
5,000 hours. See vibrator instructions.

2. Flexible Sleeve

Aside from checking the clamp tightness, there is no maintenance required on
the sleeve. Periodic visual checks should be made to see if there is damage
caused by material or solvent attack of the elastomer.

Note: Standard sleeve is Neoprene with a maximum temperature

rating of 210ÅãF and VITON with a maximum temperature
rating of 400ÅãF.

WARNING: Because of the elastomeric seals required on vibrated

equipment, the Bin Activator WILL NOT CONTAIN A
FIRE OR EXPLOSION. If a fire is in the Bin, THE AREA
SHOULD BE EVACUATED AND AVOIDED!

3. Isolators

The isolators should give years of use baring chemical attack or severe
overloading.

WHEN INQUIRING ABOUT ANY POSIBIN, ALWAYS REFER TO THE
SERIAL NUMBER STAMPED ON THE METALFAB NAMEPLATE.
