VI. SET-UP
WARNING: REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING OR MAKING
ADJUSTMENTS.
OPERATION
The VRF II Series will begin operating and the green Power LED will be illuminated when power is applied. Once
properly installed, the VRF II Series should be calibrated (refer to Calibration Section) when material is below
the probe. The status of the red Alarm LED is determined by the selected fail-safe mode and whether or not the
probe is in material. Refer to Fail-Safe Operation section. If the unit is calibrated prior to its final installation or if it
is moved from one installation to another, recalibration is required.
