CHAPTER 1. PRODUCT DESCRIPTION
FUNCTION
The VRF-1000 is a line powered (AC or DC) material level sensor that outputs a DPDT relay contact.
The electronics and probe are integral. It is a point level sensor used to detect the presence or absence
of material at a point inside a tank, bin, or other vessel. Material coming in contact with the unit’s probe
causes its output relay to change state, thereby indicating to the user the presence of material.
Operation of the VRF-1000 is based upon the Bindicator®Opti-Sense™ technology using Variable Radio
Frequency (VRF™) which automatically selects the optimal operating frequency (20kHz to 100kHz) of
the low voltage signal applied to the probe, depending on the probe circuit impedance.
A dual core microprocessor scans the probe circuit and digitally analyzed voltage and current values to
characterize the complex impedance seen by the probe. The digital signal processor continuously
analyzed the conductance and susceptance of the probe circuit and calculates when to alarm the unit.
APPLICATIONS
This model is ideal for the point level detection of granulars, powders, liquids, and slurries. In addition, it
is effective in the measurement of materials with a dielectric constant as low as 1.2.

CHAPTER 2. HANDLING AND STORAGE
INSPECTION AND HANDLING
The VRF-1000 is individually packed to provide adequate protection during shipping and has been
tested and calibrated at the manufacturing facility. When the unit is received, it should be inspected for
damage that may have occurred due to mishandling during shipping. If the unit is received damaged,
DO NOT dispose of the carton or packing materials. Notify the shipping carrier immediately. If any
problems arise, please contact Bindicator®at (800) 778.9242 or (864) 574.8060.
STORAGE
After receiving the VRF-1000, care should be taken to avoid damage. If the unit is not scheduled to be
installed immediately after delivery, the following steps should be taken:
1. After inspection, repackage the unit into its original packaging.
2. Select a clean, dry site for storage. Location should be free of vibration, shock, and impact hazards.
If the VRF™ point level unit will be in storage for more than 30 days, it must be stored in a
non-condensing atmosphere with less than 100% relative humidity.
DO NOT STORE THE UNPOWERED UNIT OUTDOORS FOR A PROLONGED PERIOD.

CHAPTER 3. MECHANICAL INSTALLATION
GUIDELINES
The probe can be mounted on the side of the vessel horizontally, or on the top of the vessel vertically.
The probe should be located out of the direct ow of material into the vessel.
MOUNTING
Consult the appropriate dimensional drawing in the Appendix for mounting information related to the
model ordered.

CHAPTER 4. ELECTRICAL INSTALLATION
GUIDELINES
The VRF™ unit is a line powered point level switch with a DPDT isolated relay contact output. Wiring
will consist of:
Grounding
Input supply line power
Output relay contacts for signal/control
CONDUIT-CABLE CONNECTION
Two threaded 0.75 in. NPT female conduit openings are provided in the housing for input and output
wiring. When only one conduit opening is used for installation, the unused opening must be sealed
with a suitable Type 4X/IP66 0.75 in. - 14 NPT plug with pipe sealant in order to maintain approval
requirements.
INPUT POWER
The VRF™ unit is either an AC or DC input model. Consult the model codes in Chapter 1 and the
nameplate of the unit to determine the proper power supply.
CONNECTION INFORMATION
See Figures 4.1 and 4.2 for location of input and output wiring.
WARNING!
Either AC or DC power is to be connected to the power input depending on the model. Consult the
nameplate of the unit and Chapter 1 to determine what type of power is required. Consult Chapter 1 for
the allowable voltage ranges.
CONNECTION INFORMATION/WIRING DIAGRAM
See Figure 4.1 for location of input and output terminal blocks. Agency approved insulated barrel type
terminals are supplied in the input terminal block to provide additional safety. These terminals must be
used in order to maintain approval requirements. See Figure 4.2 for output contact positions during
stages of operation.
WARNING!
An electrical earth ground connection must be made to the housing input ground screw located inside
the enclosure. See Figure 4.1 for location. This connection is needed for both electrical safety and
proper operation of the unit. This is required for both AC and DC units.
WARNING!
The external ground wire (included) MUST be attached to the wall or the top of the metal vessel in order
to provide the proper reference to the probe.

The output relay contacts are labeled in the un-powered alarm state. The relay is energized when the
VRF-1000 is not alarmed. This status may be opposite that of other Bindicator®brand units. If the
VRF-1000 is replacing an older Model RF-8000 or RF-9000 Series unit, connections will need to be
opposite. If a connection was made to the NC1 terminal of the RF-8000 or RF-9000 Series unit,
connect now to the NO1 terminal of the VRF-1000. C1 and C2 connections remain the same.
