Notes:

• Pointek CLS200/300 is available in two models: the standard model, and the digital model with integral local display. For information on the CLS200/300 Digital, please see manual 7ML19985JJ01.

• Pointek CLS200/300 is to be used only in the manner outlined in this instruction manual, otherwise protection provided by the equipment may be impaired.

• This product is intended for use in industrial areas. Operation of this equipment in a residential area may cause interference to several frequency based communications.

Pointek CLS200/300 is a versatile capacitance switch, ideal for level detection of interfaces, solids, liquids, slurries, and foam, and for simple pump control. The switch responds to the presence of any material with a relative dielectric constant of 1.5 or more by detecting a change in capacitance, which is registered as a change in oscillating

Pointek CLS200/300

frequency.

The switch can be set to detect before contact or on contact with the probe. The design of the CLS200 standard allows the instrument to operate independently of the tank wall or pipe, so it does not require an external reference electrode for level detection in a nonconductive vessel such as concrete or plastic. The CLS300 standard requires a connection to earth/ground for effective capacitance measurement.

The power supply is galvanically isolated and can accept voltages in the range 12 to 250 V AC/DC, depending on the application. The materials used in the probe construction provide a high level of chemical resistance, and an excellent temperature rating on the process wetted portion of the probe: up to 125 °C (257 °F) for the CLS200 and 400 °C (752 °F) for the CLS300.

Page 4 Pointek CLS200/300 Standard – INSTRUCTION MANUAL 7ML19985JH01

Page 11

Modular design and construction provide a wide choice of configurations, including rod, cable, and sanitary versions. When used with a SensGuard protection cover, the CLS200 sensor is protected from shearing, impact, and abrasion, in tough primary processes.

Pointek CLS200/300 Applications

Pointek CLS200/300 is designed for level detection and simple pump control in a variety of applications:

• Liquids, solids (powder and granules), slurries, interface detection (for example, oil/ water), and foam detection

• Foods and pharmaceuticals

• Chemical and petrochemical

• High pressure and temperature

Pointek CLS200/300 Features

• Potted construction protects components from shock, vibration, humidity, and/or condensation

Preparation

• Ensure that L3 (green) is lit.

• Turn the trip point and delay potentiometers P1 and P2 fully counterclockwise (to minimum).

• Set dip switches S1 to S4 to OFF, and S5 to ON (high sensitivity)

Configuration

1. With sensor uncovered and a minimum 100 mm (4") free space all around, turn the trip point potentiometer P2 clockwise until L1 (yellow) glows.

2. Turn P2 back (counterclockwise) until L1 stops glowing.

When S3 is set to ON, it inverts the relay function, and the functioning of S1 and S2.

Preparation

• Ensure that L3 (green) is lit.

• Turn the delay potentiometer P1 fully counterclockwise (to minimum).

• Turn trip point potentiometer P2 fully clockwise (to maximum).

• Set dip switches S1 to S4 to OFF (full potentiometer control).

•Set S5 to OFF (low sensitivity).

Configuration

1. Adjust the material level of the process so that the sensor is immersed: L1 (yellow) should glow. If L1 does not glow, reset S5 to ON (high sensitivity) The appropriate position of S5 depends on the dielectric properties of the material).

2. Adjust the material level of the process so that the sensor is uncovered, but retains as much buildup of material as possible on the sensor.

3. Adjust trip point P2 counterclockwise until L1 stops glowing. To get the true feel for the correct position, adjust P2 clockwise then counterclockwise several times to ensure that L1 stops glowing. (This adjustment is very sensitive, and we recommend repeating this exercise to finetune P2, until a very small adjustment causes L1 to stop glowing.)

Interface detection (Failsafe Low, no delay, sensitivity adjusted to detect an inter-

face)

Operation: standard

Preparation

• Ensure that L3 (green) is lit.

• Turn delay potentiometer P1 fully counterclockwise (to minimum).

• Turn trip point potentiometer P2 fully clockwise (to maximum).

• Set dip switches S1 to S4 to OFF (full potentiometer control).

•Set S5 to OFF (low sensitivity).

Configuration

1. Immerse the sensor in the material that has the lowest dielectric constant. L1 (yellow) should glow. If not, reset S5 to ON (high sensitivity).

2. Adjust P2 counterclockwise until L1 stops glowing.

3. Immerse the sensor in the material that has the highest dielectric constant. L1 should glow.

Delay alarm output

If you want to slow the Pointek CLS200/300 response, to compensate for turbulence or false readings, set a delay interval using potentiometer P1, and set S1 and/or S2 to OFF, to enable the delay for either alarm activation, alarm de-activation, or both.

If an immediate alarm output is critical, set the appropriate switch to ON, to disable the delay.

Operating Principles

In capacitance measurement1 inside a vessel or silo, the environment (typically, the vessel wall) acts as the reference electrode of a variable capacitor, and the probe supplies the measurement electrode. The dielectric (air, vapor, liquid, solid, or a combination) and, if the measurement electrode is insulated, the insulating layer.

The capacitance when the probe is uncovered (capacitance in air) will be different from the capacitance when the probe is covered (for example, capacitance in water). If the product is two immiscible liquids with different relative dielectric constants, (for example, oil and water) the capacitance will change at the interface between the two liquids.

is composed of the vessel contents

High Frequency Oscillator

The Pointek CLS200/300 probe is equipped with a high frequency oscillator which responds to the capacitance. The inverse of frequency is proportional to the capacitance. A small change in capacitance results in a large change in frequency which is easy to detect, resulting in high resolution and accuracy.

A: Technical References

Detection Range

The functional detection range depends on the relative dielectric constant of the material monitored. The detection range will be shorter when the material has a lower relative dielectric constant, and longer when it has a higher relative dielectric constant.

For definitions relating to capacitance, see the glossary, page 71

The relative dielectric constant of air (vacuum) is 1: all other materials have a higher value.

The Pointek CLS200 electrode

The Pointek CLS200 electrode is the primary sensor of the system. It supplies the electrical capacitance value. The reference is the environment at the time of setup.

The design of the Pointek CLS200 probe makes it very sensitive to changes in capacitance in the immediate vicinity of the antenna tip.

The initial capacitance of the CLS200 itself makes it possible to operate the CLS200 in a plastic tank where the Ca grounded metal tank will reduce the effects of external influences on the sensor.

The sensor can be set to detect either the change in capacitance as the product level approaches the antenna tip, or the change when the probe becomes covered.

The Pointek CLS300 electrode is the primary sensor of the system. It supplies the electrical capacitance value.

The Pointek CLS300 patented Active Shield Technology electrically isolates the measurement section and reduces the effect of any non-measurement capacitance on the measurement capacitance. (Capacitance changes could result from uncontrolled variations occurring in the connection cable, process connection, and non-active parts of the probe.) This gives a better ratio of initial capacitance to total capacitance, resulting in higher accuracy.

The measurement is further protected from interference by a buffer, which applies the frequency signal from the measurement section to the Active Shield section. This effectively

eliminates any electrical potential difference between the shield and the measurement section and prevents additional changes in capacitance occurring, especially when material builds up at the probe entrance to the tank.

specified to suit a particular application. If the measured range will be short relative to the total length of the electrode, specify a short measurement section. This increases the achievable resolution of the measurement, since any change in level will be greater relative to the length of the measurement section.

CAUTION: Possible only with the general purpose configuration; please verify against

product nameplate.

Preparation

Determine the required cable length, and subtract that amount from the actual length, to find the excess length to cut off.

For example: 10 m (actual length) minus 9 m (required length) = 1 m (excess)

Steps

1. Unscrew the cable gland compression nut to relieve the sealing cone and release the cable.

wrenches across the flat surfaces, as shown below.

a. Place two wrenches on the flat surfaces of the probe as shown: hold the probe sleeve still, and turn the lower wrench counter-clockwise to loosen the probe lower assembly.

b. Remove the lower assembly by turning the threaded electrode end counter-clockwise: this exposes the three leads, the tension block, and the steel spacer.

3. Remove the heat shrink insulation covering the solder connections.

G: Cable Modifications

4. Unsolder the connections.

Note: Do not cut the connections to the probe leads, as this can render them too short to work with later.

5. Remove the tension block, and save it for re-use in step 7.

6. Calculate the excess cable, then add back an allowance of 75 mm (3") for making the connections:

For example, 1000 mm = excess

less 75 mm

925 mm = excess cable to be removed

7. Cut off the excess cable.

8. Remove approximately 75 mm (3") of cable jacket, shield, and filler strands.

9. Cut off the excess cable core, making sure the cut is clean and square

10. Replace the steel spacer and tension block, then shorten the leads to approximately 40 mm (1.6").

11. Prepare the leads for soldering, and if heat shrink is used to insulate splices, remember to slip on the heat shrink before soldering the leads.

12. Make the solder connections and position the heat shrink to completely insulate each solder connection before shrinking it.

13. Remove any excess cable core, if necessary.

14. Apply PTFE type tape/sealant to all threads.

15. Add a pre-twist to the wires before screwing the probe sleeve and lower probe assembly together: hold the probe sleeve still, and gently turn the lower probe assembly counter-clockwise about 5 full turns. This avoids the wires being broken when the probe and probe sleeve are assembled.

16. Screw the lower probe assembly clockwise into the probe sleeve, and tighten it with a 17 mm (0.67") wrench.

17. Check that the instrument is operating correctly, using the test procedure on page 23.

Procedure

1. Loosen the three set screws and pull weight from the cable.

2. Grind/cut the cable to the required length, and then remove rough edges from the cable.

3. Ensure that cable strands are properly seated in the lay of the cable (i.e. no wire strands sticking outside the normal cable profile). Make sure ALL strands are properly seated before continuing the assembly.

4. Push the weight onto the cable while simultaneously rotating it counter-clockwise around the cable. Make sure that no cable strands are pushed out of their position in the cable and that the cable is fully inserted.

Appendix H: Application for Pointek CLS200/300 Standard

Level Detection

Note:

• For a more detailed explanation, please see

• For more detailed instructions on setting the dip switches and potentiometers, please see

The difference in capacitance between a covered probe and an uncovered probe (for example, between a probe in water and a probe in air), is used to detect level, and to protect the process from a level that is either too high or too low.

The trip point is set by potentiometer P2. This determines how large the difference in capacitance needs to be before the output is switched. Dip switch 5 allows you to adjust the sensitivity. The sensitive electronics can be set to detect the change in capacitance either as the level approaches the probe tip, or when the probe is covered.

Operation: Pointek CLS200/300 standard model

Alarm Signaling

Relay and Solid-state Switch

The relay and solid-state switch are interlinked: when the change in capacitance is greater than the setting at the trip point, the output switches. (For a diagram illustrating the relay and solid-state switch contacts, see page 25.)

Operating Principles

Fault Signaling

The Failsafe function puts the process into a safe mode of operation in the event of a fault or failure (such as a loss of power). When the Pointek CLS200/300 standard model responds to a failure, the output switches according to the Failsafe setting two Failsafe options:

Appendix H: Application

Note: The following examples assume that the pump should be turned off in the event

of a failure. If this is not the case in your process, please see the relay diagram on page 25, and make the appropriate connections to suit your application.

Failsafe High is used in applications where Pointek CLS200/300 is set to turn off a pump when the level becomes too high (probe covered, or level too close to probe). When Failsafe High is selected, the device will respond to a failure (regardless of the true level) as if it were a high level alarm (alarm ON/solid-state switch open). The pump will stop, preventing an overfill.

Failsafe Low is used in applications where CLS200/300 is set to turn off a pump when the level becomes too low (probe uncovered). When Failsafe Low is selected, CLS200/30 0 will respond to a failure (regardless of the true level) as if it were a low level (alarm ON/solidstate switch open). The pump will stop, preventing the pump from running dry.

Glossary

capacitance: the property of a system of conductors and dielectrics that permits the storage of

electricity when potential differences exist between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference, and the unit is a Farad.

capacitor: a device in a circuit that has the potential to store an electric charge. Typically a

capacitor has 2 conductors or electrodes separated by a layer of a nonconducting material called a dielectric. With the conductors on opposite sides of the dielectric layer oppositely charged by a source of voltage, the electrical energy of the charged system is stored in the polarized dielectric.

derating: to decrease a rating suitable for normal conditions according to guidelines specified

for different conditions.

Glossary

dielectric: a nonconductor of electric current.

relative dielectric constant: the ability of a dielectric to store electrical potential energy under

the influence of an electric field. This is measured by the ratio of the capacitance of a condenser with the material as dielectric to its capacitance with vacuum as dielectric.

The value is given relative to a vacuum /dry air: the relative dielectric constant of air is 1

immiscible: incapable of mixing or attaining homogeneity.

implicit: for example in “the units are implicit in pF”, the units are implied, or assumed to be pF,

because there is no other option.

miscible: capable of being mixed.

repeatability: the closeness of agreement among repeated measurements of the same

variable under the same conditions.

saturation: a condition in which any further change of input no longer results in a change of

output. For example, “the loop-current will saturate to 3.8 or 20.5 if the level exceeds the Range settings”.

solid-state device: a device whose function is performed by semi-conductors or the use of

otherwise completely static components such as resistors and capacitors.

stilling-well: a grounded metal tube with openings.

Many conductive liquids/electrolytes exhibit dielectric properties; the relative dielectric constant of water is 80.
