Introduction to the Pointek CLS 300

Note: Pointek CLS 300 is to be used only in the manner outlined in this instruction manual.

The Pointek CLS 300 capacitance level switch provides output on high or low process
material levels. When the measured material is at the desired level, the change in

capacitance is sensed and a level alarm is triggered. This could be either a high level alarm
(material rising to reach the desired level) or a low level alarm (material falling to reach

desired level).

Installation

Location

Notes:

• Installation shall only be performed by qualified personnel and in accordance with local

governing regulations.

• This product is susceptible to electrostatic shock. Follow proper grounding

procedures.

The Pointek CLS 300 as supplied in the standard probe lengths is normally mounted on the
vessel top (high detection alarm) or through the tank wall at the detection level (high or low
detection alarm).

The cable version is designed for top mounting. The cable suspends vertically so that it
reaches into the process at the desired detection level (high or low detection alarm).

Ceramic Active Shield Insulator and Thermal Isolator

Provides a ceramic Active Shield insulator and a Thermal Isolator for when the process
temperature is greater than 200E C / 392E F and/or for when the product to be detected is very
abrasive. The high temperature version is rated for applications up to 400E C / 752E F.

The Thermal Isolator provides a separation distance between a high process temperature
inside the vessel and the electronic housing outside the vessel. This reduces the operating
temperature of the electronics to a value equal to or less than 85EC/185EF.

Changing Probe Length

The probe length can be shortened in the field by cutting the electrode.

Warning: To prevent damage, do not apply torque directly to the main probe assembly.

Option 1
If the electrode is removable:

1. Remove the electrode by
releasing the set screw and
turning the threaded electrode
end counter-clockwise.

2. Place the upper part of the
electrode in a vice as shown.

3. Use a wrench to loosen the

lower portion of the electrode.

Page 10 Pointek CLS 300 – INSTRUCTION MANUAL 7ML19985CK03

Option 2
If electrode is NOT removable:

1. With unit mounted in place,

place two wrenches as shown.

2. Hold the upper wrench steady
and turn the lower one counter­clockwise to loosen the lower
portion of the electrode.

The Wrong Way

If the process connection itself is put in the vice, the probe’s internal parts will rotate along
with the wrench and the unit may fail.

Cable Tensile Strength

Do not exceed the tensile strength of the cable at 1900kg/4188lbs.

Always confirm that the load carrying capability of the silo/tank roof is sufficient to withstand
the actual force on the cable conditions, especially where the force will be, or could be, as
great as 1900kg/4188 lbs. A cable (rope) probe with a PFA jacket reduces the amount of
possible product build-up on the probe as well as the tensile force on the cable.

Cable Weights

A standard weight with optional attachable Butterfly enhancer is available for the cable
version. We recommend the Butterfly weight for lower dielectric constant materials (often in
solids) because it increases the change in capacitance when the material comes in contact
with the cable end. This occurs when the silo is quite tall (> 15 m/45 ft) and the dielectric

constant is less than (

>

< 4).

r

Shortening the Cable

Methods

• An angle grinder (preferably with a disc suitable for stainless steel)

or

• Wire cutters (suitable for piano cable

Ø6 – 9mm).

Procedure

1. Remove Butterfly (if present) from weight.

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

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

cable.

4. 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.

5. 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.

6. Re-fasten the weight by tightening the three set screws.

7. Re-attach Butterfly (if required) to the weight.

Operation

Setup

Note: Setup can be done in the field with the Pointek CLS 300 mounted into process, or in

the shop prior to mounting.

Dip Switch 1

• Set ON to change alarm relay status immediately when the sensor detects a change in

frequency. Use this setting when time is critical.

• Set OFF to change the alarm relay status with a delay by the amount set on

potentiometer #1 (P1). Use this setting when you want to slow the response to account
for turbulence or false readings.

Dip Switch 2

• Set ON to change alarm relay status immediately when the sensor detects a change in

frequency. Use this setting when time is critical.

• Set OFF to change the alarm relay status with a delay by the amount set on

potentiometer #1 (P1). Use this setting when you want to slow the response to account
for turbulence or false readings.

Dip Switch 3

• Set OFF to indicate Low fail-safe selection.

• Set ON to indicate High fail-safe selection.

Dip Switch 4

• Set ON to test the delay of the alarm relays as set by the potentiometer #1 (P1).

• Set OFF for normal operation.

Dip Switch 5

Delay ON

• Set ON for normal sensitivity on the

sensor. Use this setting when you are
measuring dry solids or non-conductive
liquids.

Delay OFF

Sensitivity

• Set OFF for low sensitivity on the

sensor. Use this setting to measure

Start Up

After the CLS is properly mounted and the switch bank set up, apply power to the unit. The
green LED (L3) lights to indicate the unit is powered and operational.

Indicators

Three LEDs indication the following:

L1 (yellow) = sensor status: When P2 is properly set, this LED indicates when

the sensor is in contact with the process material
(material capacitance is greater than set point, P2).

L1 is off when the sensor is out of contact with the
process material (material capacitance is less than
set point).

L2 (red) = output status: This LED indicates the relay and solid switch

contact status. Refer to Operation\Output Status
below.

L3 (green) = power: This LED is on when the Pointek CLS is properly

powered.

Setpoint Adjustment

As reference, and to assist adjusting the alarm setpoint for reliable and accurate detection of
the process material, we have categorized the materials and applications into two cases.

Follow the setup procedure associated with the case which includes your application.

Case 1

General applications, characterized by the following:

• dry solids

• low viscosity liquids

• hygroscopic / wet solids

• high viscosity and high conductivity liquids

Case 2

Interface detection:

• e.g. liquid A / liquid B, foam / liquid

7ML19985CK03 Pointek CLS 300 – INSTRUCTION MANUAL Page 21

Trip Amplifier

Case 1

Preparation

• Ensure that L3 (green) is ON

• Turn both potentiometers, P1 and P2, fully CCW (counter-clockwise)

• Set S1 switches 1 to 4 to OFF and S1 switch 5 to ON (normal sensitivity)

Configuration

1. With sensor uncovered and a minimum 100mm free space all around, turn P2 CW until
L1 (yellow) goes ON.

2. Turn P2 CCW until L1 goes OFF.

Case 2

Preparation

• Ensure that L3 (green) is ON

• Turn potentiometer P1 fully CCW (counter-clockwise)

• Turn P2 fully CW (clockwise)

• Set S1 switches 1 through 5 to OFF

Configuration

1. Immerse the sensor in the material that has the lowest dielectric constant. L1 (yellow)

should be ON. (If L1 does not light, set S1 switch 5 to ON [normal sensitivity].)

2. Adjust P2 CCW until L1 goes OFF.

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

come ON.

Page 22 Pointek CLS 300 – INSTRUCTION MANUAL 7ML19985CK03

Delay

The alarm actuation can be delayed for either, or both, ON alarm and OFF alarm conditions.

• Set S1-1 and S1-2. (Refer to Setup\ Switch Bank on p. 19.)

• Adjust the delay time from 1 to 60 seconds by setting potentiometer P1

Operation

After completing the setup, replace the Pointek CLS lid and lid clip. The unit is now in service,
providing level detection of your process.

Maintenance

The Pointek CLS 300 requires no regular maintenance or cleaning. Even with significant build­up on the CLS 300 level detector electrode, the level switch will continue to operate. Build-up
of material on the active shield area has little or no effect on the performance of the CLS 300.
