About 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).

One form `C' (SPDT) relay
One isolated, non-polarized, solid-state switch

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
The High Temperature version, which includes a ceramic Active Shield
insulator, is recommended when the process temperature is greater than
200EC/ 392 EF and / or when the product to be detected is very abrasive. The
high temperature version is rated for applications up to 400 EC / 752 EF. See
Temperature and Pressure Recommendations for Application on page 33.
Thermal Isolator
If the ambient temperature of the transmitter is expected to exceed
85EC/185EF, then a thermal isolator should be used. An 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 or less than 85EC/185EF.
Rod Version
The rod version of the CLS 300 is available in standard lengths from 350
mm (14”) up to 1000 mm (40”). Other lengths using stainless steel or other
metals can be attached as an electrode to the customer’s requirement.
Ensure that the thread end conforms to the exact dimensions as shown
below. Lengths of rod are not recommended beyond 1000 mm (40”).

Changing the Probe’s Length
The probe’s 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 can be removed from CLS 300 unit:
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
in the Figure.
3. Use a wrench to loosen the
lower portion of the
electrode.
Option 2
If electrode CANNOT be removed from CLS 300 unit:
1. With unit mounted in place,
place two wrenches as
shown in the Figure.
2. Hold the upper wrench
steady and turn the lower
one counter-clockwise to
loosen the lower portion of
the electrode.

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

Cable Tensile Strength
The tensile strength of the cable at 1900 kg / 4188 lbs should not be
exceeded. It is also important to confirm that the load carrying capability of
the silo/tank roof is sufficient to withstand the actual force on the cable for
any conditions where the force is likely to be as great as 1900 kg / 4188 lbs.
A cable (rope) probe with a PFA jacket reduces the possible product build up
on the probe, thus also the tensile force on the cable.
Cable Weights
A standard weight with optional attachable butterfly enhancer is available for
the cable version. For lower dielectric constant materials (often in solids) the
butterfly weight is recommended, since it increases the change in
capacitance when the material comes in contact with the cable end. This
would be the case when the silo is quite tall (> 15 m/45 ft) and the dielectric
>>>>
constant is less than (
< 4)
r
Shortening the Cable
The cable can be shortened using either:
• An angle grinder (preferably with a disc suitable for stainless steel); or
• Wire cutters (suitable for piano cable
Ø6 – 9 mm).
To shorten the cable, proceed as follows:
1. If present, remove Butterfly from weight;
2. Loosen the three set screws and remove weight by pulling it from the cable;
3. Grind/cut the cable to the required length, remove rough edges from the
cable;
4. Insure that the cable strands are properly seated in the lay of the cable (i.e.
no wire strands sticking outside the normal cable profile). It is important to
insure that this step is properly done before continuing the assembly.
5. Push the weight onto the cable while at the same time rotating it counter-
clockwise about the cable, making 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. Attach the butterfly to the weight again.

Operation
Set Up
Note:
Set up 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 the 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 the 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 the Low fail safe selection.
Set on to indicate the 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
Set on for normal sensitivity on the sensor. Use this setting in situations
when you are measuring dry solids or non-conductive liquids.
Set off for low sensitivity on the sensor. Use this setting when you are
measuring conductive liquids or wet conductive solids which are likely to
build up.

Setpoint Adjustment
In order to assist you in properly adjusting the alarm set point 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:
This is the general case encountered in most applications, characterized by
the following:
• dry solids
• low viscosity liquids
• hygroscopic / wet solids
• high viscosity and high conductivity liquids
Operation
Case 2:
Interface detection: - e.g. liquid A / liquid B, foam / liquid
PL-577 Pointek CLS 300 Page 29
Page 30
Trip Amplifier
Case 1
Preamble:
• insure that L3 (green) is `on '
• turn both potentiometers, P1 and P2, fully ccw (counterclockwise)
• set S1 switches 1 to 4 `off ' and S1 switch 5 to `on' (normal sensitivity)
1. With sensor uncovered and a minimum 100 mm free space all around, turn
P2 cw until L1 (yellow) goes `on '.
2. Turn P2 ccw until L1 goes `off '.
Case 2
Operation
Preamble:
• insure that L3 (green) is `on '
• turn potentiometer P1 fully ccw (counterclockwise), and P2 fully cw
(clockwise)
• set S1 switches 1 to 5 `off '
1. Immerse the sensor in the material that has the lowest dielectric constant.
L1 (yellow) should be `on '. If not, S1 switch 5 should be set 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 '.
Delay
The alarm actuation can be delayed for either or both `on alarm' and `off
alarm' conditions. The selection is made by setting S1-1 and S1-2, refer to
Set Up \ Switch Bank. The amount of delay is adjustable from 1 to 60
seconds by setting potentiometer, P1.
Note:
After completing the set up, 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 build-up on the CLS 300 level detector electrode, the level
switch will continue to operate. Build-up of material on the active shield area
will have little or no effect on the performance of the CLS 300.
