PRODUCT OVERVIEW
The Auto-Set™ series RF capacitance point level monitors are used for detecting high, intermediate, or low
levels of liquids, powders and free owing granular solids stored in tanks, bins, silos or other containers.
The Auto-Set series incorporates simple push-button calibration with microprocessor enable/disable switch
for total protection of stored values. Once the Auto-Set is calibrated for the application it never has to be
re-calibrated. Data is stored in non-volatile memory so it is not a󰀨ected by power loss.
A four digit LED display shows set values for uncovered, covered and trip settings, allowing simple set-up
and adjustment. A set of voltage-free changeover relay contacts are actuated when the level of the material
in the container reaches the probe. The unit incorporates a unique power shield which automatically
compensates for material build-up around the probe and on the sides of the container, preventing false
indication. The solid state electronics are housed in a weatherproof, glass-reinforced nylon enclosure.
The Auto-Set series can be top or side mounted, and are available with 220 mm, 320 mm, 1 meter and 2
meter (3, 12, 24, 36 and 48 inch) 303 solid stainless steel probes. For applications up to 10 meters (33
feet) long (maximum), 303 stainless steel wire is used to extend the probe length. The Auto-Set can be
used with container walls up to 368 mm (14.5 inches) thick (see specications).
The ush probe version (ATS8V0AI-FP) is designed for plug condition monitoring within tight tting applications.
It has a built-in mounting ange, and the probe can be inserted 32 mm (1-1/4 inches) (minimum) into a
tank or spouting with container walls up to 20 mm (3/4 inch) thick. For container walls thinner than 20 mm
(3/4 inch), the probe can be inserted farther.
For high temperature and/or high vibration applications, a remote Auto-Set version is available. Contact
4B for more information.

INSTALLATION
A thread locking compound is already applied to the probe xing stud of the AUTOSET. This will prevent
the probe rod from vibrating loose. Once tted, the compound is fully hardened after 20 minutes.
IMPORTANT: If the probe rod is removed from the unit for any reason, a thread locking compound must
be applied before the rod is retted.
When mounting all versions of the Auto-Set, care must be taken to ensure that the power shield is properly
installed.
ATS8V0AI / ATS8V0AI-300 / ATS8V0AI-400 MODELS -
The power shield is covered with a plastic sleeve with about 16 mm (5/8 inch) of bare metal exposed toward
the probe end. A minimum of 7 mm (1/4 inch) of the plastic sleeving must protrude into the vessel (Image

STANDARD WIRING DIAGRAM
All wiring must be In accordance with local and national electrical codes and should be undertaken by an
experienced and qualied electrician.
AUTOSET will operate on 110V/230V ac 50/60Hz or 24V dc supplies (Um). The unit may be wired in
ordinary un-screened cable of any length and need not be separated from other cables.
When mounting the AUTOSET, care must be taken to ensure that the exposed end of the power shield
protrudes into the container. Powershiled - Sleeve should protrude as far as possible into container and at
least a minimum of 6mm. Mount unit securely to minimise vibration.
Connect in accordance with image C, and set High/Low switch to required position (see image D), ensure
that cable gland and back cover are fully tightened when nished. The AUTOSET has two 20mm cable
entries, one of which is blank, the blank may be drilled out carefully if required; it must not be knocked out.
All cable glands must be ATEX approved, IP65 rated. The unit should be wired and earthed in accordance
with appropriate Electrical Regulations. The Auto-Set must be grounded using the unit ground screw
located on the outside of the housing (Image C). The internal wire terminal is already connected to the
terminal ground point from the factory (Image C), do not remove this connection.
On metal bins and silos, the Auto-Set must be grounded to the container. If the bin or silo is non-metallic,
the metal anges or couplings used to mount the Auto-Set should be grounded. This also applies to probes
mounted in wooden or plastic tops of metal bins.
NOTE
The Auto-Set must be grounded using the unit ground screw located on the outside of the housing. The
internal wire terminal is already connected to the terminal ground point from the factory, do not remove
this connection.

SENSOR OPERATION
PAGE 12
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.

SENSOR CALIBRATION
The Auto-Set can be calibrated automatically, manually or by a combination of the two methods.
Usually, automatic calibration is the simplest method, particularly when the vessel can be lled to cover
the probe.
Manual calibration is useful when a number of probes in similar applications need to be set. Once the
correct calibration has been determined and noted, on one system, the remainder can be set to the
same setting.
AUTOMATIC CALIBRATION (MATERIAL AVAILABLE) -
1. Set Park/Cal switch (A - Image D) to Cal and Auto/Man switch (C - Image D) to Auto. The Cal
LED will ash.
2. Ensure that the probe is uncovered and press and hold the “Probe Un-Covered / Lower”
button (F - Image D) button. The display will show UXXX followed by RXXX.
3. Fill the vessel su󰀩ciently to cover the probe and then press the “Probe Covered / Raise”
button (E - Image D) button. Display will show CXXX followed by RXXX.
4. Return the Park/Cal switch (A - Image D) to park. The unit is now calibrated. UXXX and
CXXX values can be viewed but not altered by pressing the “Probe Un-Covered / Lower” and
“Probe Covered / Raise” buttons together.
SEMI-AUTOMATIC CALIBRATION (MATERIAL NOT AVAILABLE) -
5. Follow steps 1 & 2 above.
6. Set Cal/Park switch (A - Image D) to Park and press the “Probe Un-Covered / Lower” button
(F - Image D) button. Note the UXXX reading but ignore the RXXX reading. Return the Cal/
Park switch (A - Image D) to Cal and set the Auto/Man switch (C - Image D) to Man.
7. From Table A below, select the nearest material type to be detected for your application and
add the value to the UXXX reading determined in step 6.
8. Press the “Probe Covered / Raise” button (E - Image D) button to raise the reading and
the “Probe Un-Covered / Lower” button (F - Image D) to lower the reading to achieve the
calculated setting from step 7.
9. Return the Cal/Park switch (A - Image D) to Park and press and hold the “Probe Covered /
Raise” button (E - Image D) to conrm that the relay operating point RXXX is correctly set.

POWER SHIELD OVERVIEW
The Auto-Set detects material by radiating a high frequency (RF) signal from the probe. The advanced
electronics of the Auto-Set use this signal to measure the capacitance inside the vessel with respect to
ground and thus indicate when material has reached the Auto-Set probe.
The power shield creates a barrier and enables the unit to ignore a certain amount of material built up
on the probe, helping to prevent false readings. The Auto-Set is available in four power shield lengths,
and can be used with walls that are up to 368 mm (14.5 inches) thick. Installation through thick concrete
silos only requires a 25.4 mm (1 inch) diameter hole for probe insertion.

TESTING AND COMMISSIONING
1. Check that the unit is correctly installed (see standard wiring diagram).
2. After going through the sensor calibration steps, the green LED should be “ON”.
3. Introduce material to the Auto-Set. If calibrated correctly, the Auto-Set will activate when material
has been detected. Machinery shut down will depend on your specic monitoring setup. 4B
recommends an instant shutdown when maximum ll level or a plug condition has been detected.
WARNING
If the system does not immediately shutdown as expected or alarm as required, then remove the
machine from service until the problem has been diagnosed and corrected.
