4.3 Operating principle

The sensors detect filling levels of liquids or solids - either in direct contact with the medium, or
through a non-metallic container wall. The capacitive sensors are also designed for the non­contact and wear-free detection of both metallic (electrically conductive) and non-metallic
(electrically non-conductive) objects.

4.4 Functions and operating modes

When delivered, the device functions as a proximity switch with a rated operating distance of 5
mm (BCT5-S18- ...) or 10 mm (BCT10-S30 ...). Additional functions can be taught by the user.

4.4.1 Setting options

The devices can be set via IO-Link with FDT tools such as PACTware™ or via the PLC software.

The capacitive sensors are also provided with additional setting options:

■

Setting via teach adapter (optional accessories, not included)

■

Settings made via manual bridging via pin 5 to UB or pin 5 to GND

■

Setting via pushbuttons (for models with teach buttons)

4.4.2 “Medium present” mode (Full teach)

In “Medium present” (Full teach) mode, the device operates with minimum sensitivity. This is
useful for applications with easy to detect media. A switch point is taught for when a medium
or an object is present in the sensing range of the sensor.

The switch threshold for the “Medium present” mode is automatically set so that a safety re­serve is produced for the switchoff limit. The safety reserve can be set via FDT/IODD. The switch
point is below the measured capacitance. Environmental factors such as temperature devia­tions, condensation, the formation of film or pollution have less effect on the signal in “Medium
present” mode. The switch point can be set with the “Medium present” teach button. The inter­val between two teach operations can be set to any length as required.

4.4.3 “Medium not present” mode (Empty teach)

In “Medium not present” (Empty teach) mode the device operates at maximum sensitivity. Pos­sible uses include applications in which pre-actuation by the environment must be prevented.
The switch point is taught when no medium or object is present in the detection range of the
sensor.

The switch threshold is automatically set for the “Medium not present” mode so that there is a
safety reserve for the switchoff limit. The safety reserve can be set via FDT/IODD. In this case, the
switch point is above the measured capacitance. Environmental factors such as temperature
deviations, condensation, the formation of film or pollution have less effect on the signal in
“Medium present” mode. The “Medium not present” teach enables the switch point to be set.
The interval between two teach operations can be set to any length as required.

11

2016/09

BCT-... Capacitive Sensors

4.4.4 “Switch point between medium present and medium not present” mode (Complete teach)

“Switch point between medium present and medium not present” mode is suitable for appli­cations with difficult environmental conditions or media with little contrast. This requires the
“Medium present” and “Medium not present” teach operations to be carried out in succession.
The switch point is in the middle of the capacitances measured with the two teach operations.

In “Switch point between medium present and medium not present” mode, the difference
between the full and empty state of a container can be detected.

4.4.5 Internal voltage and temperature monitoring

The device is provided with internal voltage and temperature monitoring. The monitoring func­tion provides information to determine the load and failure probability of the sensor.

4.5 Technical accessories

The accessories are not supplied with the device and must be ordered.

5 Mounting

The sensors can be mounted in any position (orientation). The maximum tightening torque for
fastening the sensors is 2Nm (BCT5-S18-…) or 5Nm (BCT10-M30-…).

➤ Clean the mounting surface and the surrounding area.
➤ When using a mounting bracket: Fasten the sensor in the mounting bracket.
➤ Install the sensor or the mounting fixture at the intended location.
➤ Make sure that the connector on the rear of the sensor remains accessible.
➤ Observe the minimum mounting distances.

BCT5-S18-… BCT10-S30-…

Distance D 36 mm 60 mm

Distance W 15 mm 30 mm

Distance S 27 mm 45 mm

Distance G 30 mm 60 mm

Fig. 3: Minimum installation distances

➤ When using more than one sensor in the application: Avoid the overlapping of the electrical

fields. This overlap can occur if two sensors are mounted less than 36mm (for BCT5-S18-…)

or 60mm (for BCT10-S30-…) apart.

In this example, the sensor for detecting poorly detectable media (e.g. sticky adhesive liquids)
in a tank has to be taught. For this a switch point must be taught between “Medium present”
and “Medium not present”.

➤ Reset sensor to factory settings.
➤ Level detection - Teach the sensor when the tank is full: Carry out “Medium present” teach.
➤ Level detection - blank out the wall when tank is empty: Carry out “Medium not present”

teach.

➥ The switch point is in the middle of the measured capacitances measured at teaches “Medium

present” and “Medium not present”.

NOTE

The “Medium present” and “Medium not present” teaches can be made in any order
and with any time interval.

10 Troubleshooting

If the device does not function as expected, first check whether ambient interference is present.
If there is no ambient interference present, check the connections of the device for faults.

If there are no faults, there is a device malfunction. In this case, decommission the device and
replace it with a new device of the same type.

11 Maintenance

The proper condition of the connectors and cables must be checked regularly.
The devices are maintenance-free, if necessary, clean with a damp cloth.

12 Repair

The device must not be repaired by the user. The device must be decommissioned if it is faulty
and sent to Turck. Also observe here the specific warranty conditions agreed with the shipment.

12.1 Returning devices

If a device has to be returned, bear in mind that only devices with a decontamination declara­tion will be accepted. This is available for download at

http://www.turck.de/static/media/downloads/01_Declaration_of_Decontamination_EN.pdf

and must be completely filled in, and affixed securely and weather-proof to the outside of the
packaging.

13 Decommissioning

➤ Remove the connection cable from the power supply and/or processing units.
➤ Remove the connection cable from the sensor.
➤ Undo the connections of the sensor or the mounting bracket from the mounting area.
➤ If necessary, undo the connection of the sensor to the mounting bracket.

14 Disposal

The devices must be disposed of correctly and must not be included in normal household
garbage.
