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
VRF1A are AC powered units and accept any voltage between 85 VAC and
265 VAC. Models beginning with VRF1D 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-1000 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-1000 will automatically begin a 3
second calibration operation. If the unit is powered on the bench prior to instal-
lation, 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-1000 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-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 unit,
connections will need to be opposite. If a connection was made to NC1 terminal of the
RF8/9000, connect now to the NO1 terminal of the VRF-1000. C1 and C2 connections
would remain the same.
