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).

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”).

Configuration
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.

Installation
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
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 (>
>>
>r< 4)
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.
