INTRODUCTION

The BinMaster VR Vibrating Rods are point level controls used to detect the presence or absence of granular or powdered material. The Vibrating Rod operates by exciting the blade of unit to causing it to vibrate at its mechanical resonance frequency of about 290 Hz. When material covers the blade of the probe, the vibration stops. This is sensed by the electronic circuitry causing the relay contacts to change states.

When the blade becomes uncovered, the vibration will restart and the relay contacts will change back.

Since only the end of the vibrating blade is sensitive and not the base, build-up on the container wall has no influence on the sensor. The shape of the blade and its vibration have a self cleaning effect.

VERSIONS

The BinMaster VR is available in 2 different versions:

•VR-21 - 1 1/2 in. NPT Mount, Standard Insertion Length 7.5 in. (190mm)

•VR-41 - 1 1/2 in. NPT Mount, Insertion Length extended from 14in. to 13 feet by a tube which is screwed between the vibrating probe and the mounting socket.

3.1

SPECIAL SEDIMENT MODEL

Application: The BinMaster VR-SED is a special configuration of the VR-21 / VR-41 level control instrument. It is designed to detect the level of solid material that has settled in water. A typical application is the detection of sand in front of pumping systems.

925-0289 Rev C 5

Function: A piezo system brings rod to vibrate at its resonant frequency. The vibrating system is tuned to work in water. If solid material covers the rod, it damps the vibration. An electronics circuit switches a binary output signal. When the rod gets uncovered, it starts vibrating again and the output switches back.

SPECIAL INSTRUCTIONS FOR SEDIMENT MODEL VIBRATING ROD

General: This special sediment model vibrating rod is tuned to work (vibrate) in water. This means that it may not vibrate in air which would result in a covered indication. To test the sediment model vibrating rod, you have to put the vibrating blade into water. The sediment model is not usable for detecting liquids or solids in air. The blade of the BinMaster VR-SED must have a distance of at least 4 inches

(100mm) to the container wall. If the blade gets closer than this to the container wall, then the vibration could be damped by reflections of the container wall.

Sensitivity: For the sediment model vibrating rod, only the sensitivity settings B or C can be used.

This setting depends on the weight of the settled material and the water/material mixture.

B Higher sensitivity: The vibration gets damped earlier than on position C. Depending on the density of the material, the relay will switch when the water/material mixture on top of the settlement just reaches the vibrating blade.

C Lower sensitivity: The vibration gets damped later than on position B when the vibrating blade gets fully covered by the settled material.

INSTALLATION

4.1

Location and Mounting

Figure 1 shows the typical installation possibilities of the BinMaster VR units.

The BinMaster VR is installed by screwing the male mounting threads into a 1 1/2” NPT coupling or mounting flange. Use a 2 inch (50mm) wrench to tighten the unit into the mounting socket. If side mounting the

VR, it must be turned until the blade is vertically oriented, so that material can flow freely over the blade and does not rest on it causing false alarms. Use the round indention on the 2 in. hex collar to identify the blade orientation. When the indention in up the blade is oriented correctly. Refer to Figure 1 for a view of blade orientation

WARNING: Do not screw in by turning the enclosure housing!

Mounting Locations

CORRECT !

Blade is mounted vertical.

WRONG !

Blade is mounted horizontal.

The conduit entries must always point downwards to prevent moisture from seeping inside the housing. If the housing is not in the correct position after the probe has been firmly screwed into the bin wall, proceed as follows:

•Remove the cover of the housing.

•Unscrew and remove the 3 mounting screws for the upper pc board.

•Remove the upper pc board. Be careful not to bend the interconnect pins on the bottom of the pc board.

•Unscrew and remove the 3 hex standoffs that secure the lower pc board.

•Remove the lower pc board. The wires from the probe do not need to be removed from the pc board, but care should be taken not to damage the pc board or wires.

•Use a 10mm wrench or socket to loosen and remove the nut that secures the housing to the vibrating rod assembly.

•Lift off the housing from the vibrating rod assembly. Take care not to damage the wires or the pc board.

•The housing can to rotated in 90° steps to achieve and orientation that has the conduit entries pointing downward.

•Place the housing back on the vibrating rod assembly so that the tube for the wires is in one of the

4 notches in the housing.

•Replace the flat retaining washer and flat washer and screw the nut back on the stud from the vibrating rod assembly. Firmly tighten the nut.

•Replace the lower pc board and secure it with the 3 standoffs.

•Replace the upper pc board. Be sure to align all of the interconnecting pins on the bottom of the upper pc board and plug the 2 boards together.

•Secure the upper pc board with the 3 mounting screws.

4.2

Input Power and Field Wiring

The BinMaster VR units have a wide voltage range power capable of being powered from any voltage from

20 volts to 250 volts AC or DC.The terminals on the pc board for the power supply and the relay contacts allows for a maximum conductor size of 12 AWG. An equipment grounding connection (earth ground) should be supplied to the unit for safety. See the diagram below for terminal and component identification.

Field wiring should conform to all national and local electrical codes and any other agency or authority having jurisdiction over the installation.

FAIL-SAFE SELECTION

5.1

Description

A Fail-Safe condition means that the relay contact positions are set up so that in the event of a power failure the relay will be de-energized and the contacts will indicate a condition that is deemed safe for the application. (Refer to Figure 2 for the location of the Fail-Safe selection switch.)

5.2

Fail-Safe High

Fail-Safe High means that the relay will be energized when the probe is uncovered and will de-energize when the probe is covered. In this mode, a power failure will cause the relay contacts to indicate that the probe is covered whether it is or not.

Fail-Safe Low means that the relay will be de-energized when the probe is uncovered and will energize when the probe is covered. In this mode, a power failure will cause the relay contacts to indicate that the probe is uncovered whether it is or not.

Use this setting only for very light material with densities down to 1.25 lb./cu. ft., (20g/l) The sensitivity is very high at this setting.

Pos. B:

Pos. C:

Standard setting, sufficient for most materials.

For heavy materials with high densities which may form a deposit on the vibrating blade. As the sensitivity of the instrument is low at position C, very light material such as expanded styrofoam cannot be detected at this setting.

For special model SEDIMENT VR only B or C must be used, see special instructions for SEDI-

LED

The LED on the pcb is a visual indication of the status of the vibrating rod relay. The LED will be flashing when the relay is de-energized and will be ON solid when the relay is energized. The Fail

8.0 REMOTE ELECTRONICS INSTALLATION

In some applications such as excessive vibration or ambient temperatures above +140° F, it may be necessary to locate the electronic circuit board away from the vibrating rod. In these applications, a separate remote enclosure is used to mount the circuit board, and a special cable with individually shielded conductors is used to interconnect the circuit board to the vibrating rod unit.

The remote electronics option is available for the VR-21 and VR-41 vibrating rods.

Figure 5 shows the mounting hole locations for the remote electronics enclosure. The interconnecting cable connections are also shown in Figure 5. The input power is supplied to the remote electronics and an the special individually shielded conductor cable is routed between the remote electronics and the vibrating rod. The interconnect cable will have a wire connecting terminal “T” on the remote board to terminal “T” in the vibrating rod; terminal “R” on the remote board to terminal “R” in the vibrating rod; and signal ground on the remote board to signal ground in the vibrating rod.
