P ointek CLS 200 analog model

Notes:

• Pointek CLS 200 is to be used only in the manner outlined in this instruction manual, otherwise protection provided by the equipment may be impaired.

• Pointek CLS 200 is available in two models: the analog model, and the digital model with integral local display. Part I of the manual only discusses the analog model. Please see Part II, page 27 onwards, for information on the digital model

Pointek CLS 200 is a versatile capacitance switch with a high level of chemical resistance; 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 dielectric constant of 1.5 or more by detecting a change in capacitance, which is registered as a change in oscillating frequency. It can be set to detect before contact or on contact with the probe. The design 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 non-conductive vessel such as concrete or plastic.

The power supply is galvanically isolated and accepts a wide range of voltages (12- 250 V AC/DC). The stainless steel and PPS provide a high level of chemical resistance, and a temperature rating up to 125 on the process wetted portion of the probe.

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

Specifications: analog

Application: Pointek CLS 200 analog model

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 P1. 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 antenna tip, or when the probe is covered.

Operation: Pointek CLS 200 analog model

Alarm Signalling

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 20.)

• high alarm: alarm ON/switch open when level is higher than the set point (probe becomes covered

)

• low alarm: alarm ON/switch open when level is below the set point (probe becomes uncovered)

The setting is selected by turning dip switch 3 on or off.

Fault Signalling

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 CLS 200 analog model responds to a failure, the output switches according to the Failsafe setting options:

• Failsafe High

• Failsafe Low

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 20, and make the appropriate connections to suit your application.

Failsafe High is used in applications where Pointek CLS 20 0 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 CLS 200 is set to turn off a pump when the level becomes too low (probe uncovered). When Failsafe Low is selected, CLS 200 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.

Preparation

1. Ensure green power light L3 is on.

2. Turn the delay potentiometer P1 and the trip point potentiometer P2 fully counterclockwise (minimum delay and minimum sensitivity respectively).

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

4. Set switch S5 ON (high sensitivity).

Test Procedures

Test the sensitivity of the sensor:

• Slowly turn the trip point potentiometer P2 clockwise until the yellow sensor status light L1 glows. Shortly afterwards, the red output status light L3 will glow. This concludes the sensitivity test.

Test the delay:

1. Turn the trip point potentiometer P2 fully counterclockwise (minimum sensitivity).

2. Turn the delay potentiometer P1 about 1/8 turn clockwise (delay set point).

3. Slowly turn the trip point potentiometer P2 clockwise until the yellow sensor status light L1 glows. After an appropriate delay the red output status light L3 will glow. This concludes the delay test.

Test the switch function:

1. Turn the delay potentiometer P1 and trip point potentiometer P2 fully counter clockwise (minimum delay and sensitivity respectively).

2. Slowly turn the trip point potentiometer P2 clockwise until the yellow sensor status light glows.

3. Slightly turn the trip point potentiometer P2 counterclockwise until the yellow sensor status light just stops glowing. Grasp the probe with your hand. The yellow sensor status light L1 will glow, indicating switch function. After an appropriate delay the red output status light L3 will glow. This concludes the switch function test.

Delay Settings: S1 and S2

Operation: analog

Use the delay function to slow the response, and compensate for turbulence or false readings.

• Delay potentiometer P1 can be adjusted to set a delay time from 1 to 60 seconds.

• Two separate delay settings are controlled by S1 and S2:

- for alarm activation (alarm ON)

- for alarm de-activation (alarm OFF)

• When switches are OFF (open) the delay is enabled.

• The position of Failsafe switch S3 determines how S1 and S2 function.

S5-ON High sensitivity Use this setting for measuring dry solids or non-

conductive liquids.

S5-OFF Low sensitivity Use this setting for measuring conductive liquids, or

viscous conductive solids that can build up on the sensor.

Test settings: S4

• When S4 is set to ON, it inverts the signal, allowing you to test the delay settings from P1, or to verify that S1 and S2 are in the correct position.

S4-ON Enable test Observe the response of the output status and sensor

status LEDs to verify the delay interval set by

potentiometer P1.

Setup

WARNING: It is essential to check settings during the process itself, and confirm that they are correct, before regular operation commences.

Initial setup can be carried out prior to mounting into the process, but it is extremely important to calibrate the unit and adjust the sensitivity on the product itself.

For a simple application, set Pointek CLS 200 to Low alarm/no delays:

• turn P1 fully counter-clockwise (no delay interval)

• set dip switches S1, S2 and S5 to ON, S3 and S4 to OFF

S1-ON Delay disabled

S2-ON Delay disabled

S3-OFF Low alarm • probe uncovered = alarm ON/relay de-energized

S4-OFF Test function disabled • normal operation

S5-ON High sensitivity

General applications (Failsafe Low, no delay)

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.

Demanding applications (Failsafe Low, no delay, sensitivity adjusted for viscous, con-

ductive material)

Preparation

• Ensure that L3 (green) is lit.

Operation: analog

• 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)

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).

Page I – 24 Pointek CLS 200 (analog) – INSTRUCTION MANUAL 7ML19985AR02

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 CLS 200 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.

The functioning of S1 and S2 depends on the alarm setting:

Operation: analog

High alarm/

overfill protection

Low alarm/

dry run protection

To test the delay function, follow the test procedure on page 18.

S1-ON disables delay of alarm de-activation (alarm OFF)

S2-ON disables delay of alarm activation (alarm ON)

S1-ON disables delay of alarm activation (alarm ON)

S2-ON disables delay of alarm de-activation (alarm OFF)

Operation

After completing the setup, replace the lid and secure the lid clip. Pointek CLS 200 (analog model) is now ready to operate.
