PRE-INSTALLATION CONSIDERATIONS

Choosing a Location: (See Figure 1)

1) Material Flow - When selecting a location for any rotary pad-

dle bin monitor, choose a point in the vessel where the paddle
will be out of the direct flow of incoming and outgoing materi­al to prevent any mechanical damage that may be caused by
the pressure of the flow. This is particularly important for
materials with large, lumpy characteristics.
must be positioned at a point where incoming material will
reach and cover the paddle in its normal flow, and when
receding, will flow away from the paddle in an even manner.

2) Vibration Concerns - Mount at a location that is subject to
limited vibration, away from bin vibrators thereby attaining
maximum operational life. Consult the factory when ques­tionable conditions exist.

3) Guard Reinforcement - When using shaft extensions and
guards in top mounted applications, select a location where it
is feasible to reinforce the guard to the vessel wall. See
Mechanical Installation portion of this bulletin for further
details.

sponds to the outer diameter of pipe coupling. In side mount
applications, position a half-coupling flush with the inside of
the vessel and weld into place. In top mount applications,
position a full coupling halfway into the vessel and weld into
place. After greasing the mounting threads with anti-seize
compound, thread the rotary paddle bin monitor into the cou­pling and position the conduit entrance to minimize moisture
infiltration. Attach paddle if applicable. (See Figure 2)

2) Plate Mounting - Using the gasket provided with the mount­ing plate as a template, drill six holes at the diameter applica­ble to the attachment method being used. Drill six clearance
holes at 11/32 inch (9 mm) diameter for use with 5/16" bolts.
The bolts may be secured by tack welding the bolt heads to
the vessel, or by an adjoining nut. Cut a hole (suggested size
2-5 inches (50-125 mm)) centered within the bolt circle to
allow an attached paddle to fit within the bin. Attach gasket
and mounting plate to the vessel positioning the conduit
entrance to minimize moisture infiltration. (See Figure 4)

Extension/Guard Installation: (See Figure 5)

1) Typical Configuration - Rigid extensions are recommended

for top mount applications only and should be always accom­panied by a flexible coupling. Shaft guards are recommend­ed whenever extensions are longer than 18 inches (457 mm).

Guard Reinforcement

2)

- Mechanical reinforcement of the
shaft guard should be considered whenever a guard length
greater than 72 inches (1.8 m) is used. The guard should be
anchored to the sidewall with braces to reduce mechanical
stress at the connection point of the guard.

3) Guard/Extension Multi-Stage Assemblies - It may be nec­essary to connect multiple short pieces to ultimately achieve
the desired length. In all cases, extensions and guards
should not exceed 144 inches (3.6 m). Shaft extensions can
be simply connected one to another

. Guards must use a

1-1/4" full coupling as an interface between sections.

4) Cable Extensions - Lengths up to 78 inches (2.0 m) are per­mitted. Length can be shortened in the field as required. See
instructions provided with cable extension for details.

Hi-Temp Models:

1) Mounting - Carefully handle the hi-temp. gasket provided

with the assembly. Using it as a template, mark the locations
of the six boltholes on the vessel. Drill six holes at the diam­eter applicable to the attachment method being used (i.e.
tapped holes or clearance holes for bolt/nut combination).
For example, drill six clearance holes at 11/32 inch (9 mm)
diameter for use with 5/16" bolts. The bolts may be secured
by tack welding the bolt heads to the vessel, or by an adjoin­ing nut. Cut a hole (suggested size 2-5 inches (50-125 mm))
centered within the bolt circle to allow the paddle when
attached to the bin monitor to fit within the bin. Attach gasket
and hi-temp. paddle unit to the vessel positioning the conduit
entrance in a manner, which restricts moisture infiltration.

2) Extensions/Guards - Use of extensions are permissible on
Hi-Temp units also. (See Extension/Guard Installation sec­tion). Installing guards on Hi-Temp models requires in-field
modifications. Consult Omega for guidance.

Effective Cooling- The Hi-T

ging pipe, which thermally insulates (via lag pipe material and
physical separation) the internal bin temperature from the
paddle unit thereby protecting its critical components. This
technique is very effective but is dependent on careful con­sideration of ambient air temperature surrounding paddle unit,
thermal conductivity of the material being sensed, and the
actual temperature present at the mounting point. The follow­ing chart is intended to provide general guidance for installa­tion. Each application should be evaluated to insure that the
rated temperature of the electronics is not exceeded. In addi­tion, an air connection is provided on the lagged pipe to fur­ther increase the cooling capacity of the system. When appli­cable, connect airline to 1/2" coupling provided on Hi-Temp.

exceed the bin pressure to be effective. The air should be

ELECTRICAL INSTALLATION

1) Hazardous Location Precautions - (See Safety and
Specifications sections of this manual before starting electri­call installation.) Observe all government regulations
regarding equipment in hazardous locations. In particular, for

approved explosion-proof products, install a conduit

CSA
seal fitting within 2 inches (50 mm) of the rotary paddle bin
monitor. On all models ensure power is disconnected when­ever the cover is removed and upon completion ensure cover
is completely re-attached.

2) Factory Wiring - The LVD-800 Series motor leads are
prewired to the PCB at the designations labeled "M1" and
"M2". DO NOT alter or make additional external connection
to these terminals. Doing so will likely cause damage to the
LVD-800 Series.

3) Permanently Connected Equipment - Disconnecting
devices shall be included in the system installation. In instal­lations were multiple circuits are used, individual disconnects
are required. The disconnects shall be within close proximity
of the equipment, accessible to operators, and marked appro­priately as the disconnect for the associated circuit. Assure
the disconnect ratings are appropriately sized for the circuit
protected (See Specifications).

4) Circuit Separation - Since the LVD-800 single wiring com­partment can not absolutely protect against physical contact
between multiple circuits, it is required that all wiring used
must have an insulation rating of 300v minimum, and a tem­perature rating of 176˚F (80˚C) minimum.

5) Protective Earthing - Each LVD-800 is provided with a
"protective conductor terminal" which shall be terminated
to the local earth ground potential to eliminate shock hazard.
Select wire size that can carry in excess of the sum of all cir­cuit's maximum amperage.

6) Power Input - Verify the intended voltage supply is com­patible with the voltage configuration indicated on the elec­tronics and the external nameplate. Connect power as shown
in Figure 6. The 24 VAC/DC model must be supplied by a
SELV source. Observe polarity when using a VDC source.

7) Sense Output Contacts - The LVD-800 is equipped with a
set of isolated contacts (SPDT) which indicates whether or
not material is being detected within the vessel (See Figures
6-8). This output is also influenced by the selection of the
"fail-safe" switch as described in the "Setup" section of this
manual. The designations on the circuit board relate to the
contact status when the relay is de-energized (e.g. the mate­rial is "not" sensed and the fail-safe switch is in the "low"
mode).

8) Fault Output Contacts - The LVD-800 is equipped with a
set of isolated contacts (SPDT) that indicates whether or not
the unit's self-diagnostics detected successful operation (See
Figures 6-8). The designations on the circuit board relate to
the contact status when the relay is de-energized (e.g. the
power is removed or when an internal error is detected). In
normal operation, the "fault" relay will be energized resulting
in a closed "normally open" contact, and an open "normally
closed" contact. This output can be wired in tandem with the
Sense Output Contacts to provide an output that combines
the material sense and fault detection on a single wire set.

tics. The "sense" output will default to the no-material sensed
state (Note: influenced by "fail-safe" switch setting). The

Figure 7

Fail-Safe (See Figure 8)

The "fail-safe" switch setting only influences the "sense" output
(never affects the "fault" output). Generally the "fail-safe" switch
is set so in the event of a power failure, the "sense" output will
default to the application’s critical state condition.

1) High Fail-Safe - The "sense" output will de-energize when
material is sensed at high level or with power loss.

2) Low Fail-Safe - The "sense" output will de-energize when
material is below low level or with power loss.

Designations on the electronics refer to the relay contact status
when no material is sensed and the "low" fail-safe is selected
(Relay is de-energized). Contacts are reversed when no materi­al is sensed and high fail-safe is selected (Relay is energized).
