The VRF-1000R Remote model must only be installed and
operated as described in this operating instruction. Please
note that other action can cause damage for which
Bindicator®does not take responsibility. If the model is not
installed correctly or used in approved applications,
dangers may arise such as product overflow.
Ensure that all personnel installing, wiring, and calibrating this device are
suitably qualified.
Observe all local and national electrical codes for the wiring of this device.
IMPORTANT!
Either AC or DC power is to be connected to the power input depending on
the model. Consult the nameplate of the unit. Models beginning with
VRF1REA are AC powered units and accept any voltage between 85 VAC
and 265 VAC. Models beginning with VRF1RED are DC powered units and
accept any voltage between 9 VDC and 36 VDC.
IMPORTANT!
An electrical earth ground connection must be made to the housing input
ground screw. See Figure 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.
External ground wire must be connected to tank wall or top of tank.

Start-up & Operation
The VRF-1000R Remote model will automatically begin operation when
powered up. It should be initially powered after it is installed in the application
and with material below the probe. When initially powered up, the VRF-1000R
Remote model will automatically begin a 3 second calibration operation. If the
unit is powered on the bench prior to installation, or moved from one installation
to another, recalibration is required. Momentarily press the recalibration
pushbutton. The green calibration indication LED will go off, and after 3 seconds
illuminate to indicate calibration is complete. The VRF-1000R Remote model is
shipped from the manufacturer with the automatic calibration/recalibration
feature enabled. If only manual pushbutton calibration/recalibration is desired,
set SW1 DIP switch position 6 to off.

Failsafe Selection
High Level Failsafe Operation
· DIP Switch SW1 position 5 is on.
· If the electrical power fails, the relay turns off. This indicates material
as if the tank were full.
Low Level Failsafe Operation
· DIP Switch SW1 position 5 is off.
· If the electrical power fails, the relay turns off. This indicates material
as if the tank were empty.
The output relay contacts are labeled in the un-powered alarm state. The relay is energized
when the VRF-1000R is not alarmed. This status may be opposite that of other Bindicator®
brand units. If the VRF-1000R is replacing an older Model RF unit, connections will need to
be opposite. If a connection was made to NC1 terminal of the RF, connect now to the NO1
terminal of the VRF-1000R. C1 and C2 connections would remain the same.
