SENSOR OPERATION
PAGE 10
FAIL SAFE SETTING -
The “High/Low” switch (D - Image D), sets the fail safe mode. In the “High” position, the relay is energized
without material present. In the “Low” position, the relay is energized with material present. Normally,
the “High” position is used for high level probes and the “Low” position for low level probes. Intermediate
probe settings depend upon individual requirements.
ELECTROSTATIC RISK - Ensure that the enclosure is not subject to charging in end application.
PARK MODE -
In normal operation, the LED display shows a value representing the capacitance measured by the probe
at the time.
Pressing and holding the “
Probe Covered / Raise”
button (E - Image D) will cause the display to
show CXXX followed by RXXX.
Pressing and holding the “
Probe Un-Covered / Lower”
button (F - Image D) will cause the display
to show UXXX followed by RXXX.
CXXX is the probe covered value measured during calibration, UXXX is the uncovered value and RXXX is
the relay operating point which the Auto-Set calculates and is half way between the two measured values.
NOTE
In park mode, settings are “View Only” and cannot be altered.
