4 . FeatUres oF variants
3 . brieF
Capacitive level sensors (switches) CLS–23 are designed for limit level detection of electrically
conductive and non-conductive uids in vessels, reservoirs, sumps, pipes, tanks, etc. The sensitiv-
ity of the sensor can be easily set by placing magnetic pen on sensitive spot.
The process coupling at the housing can be with metric thread (M18x1.5 ; M20x1.5), pipe thread
(G3/8” ; G1/2”) or sealing thread (NPT 1/2–14). Output performances – transistor output with open
collector (PNP), two wire electronic switch (S) and NAMUR output.
There are next performances available: N – Normal for non-explosive areas, E – Extended tem-
perature range for non-explosives areas, Xi – Explosion proof (intrinsically safe for explosive ar-
eas), NT – High temperature variant for non-explosives areas and XiT – High temperature variant
for explosive areas.

6 . moUnting recommendation
CLS-23 level sensors can be xed in a vertical, horizontal or bevelled position into the shell of the
vessel, the storage tank for the xation console in the pit, by screwing into the welding ange, using
a xing nut or NPT process connection.
Basic application recommendations are mentioned below.
During assembly into the metal tank or the storage tank, it is not necessary to separately ground the
base of the level sensor. In the case of installation in concrete tanks or silos, it is recommended to
install a level sensor on the auxiliary metal construction (console, cap, etc.) and to then connect it
using a permanently dipped metal item or with steel reinforcement in the concrete (armouring).
In the case of the reading of an aggressive medium, we recommend that the producer be consulted.
If the sensors are tted with protective caps at the ends of the electrodes, remove the
caps before commissioning.
For top mounting (vertical position) it is necessary to keep the
distances from walls and from other sensors.

When installing the sensor into the pipe it
is necessary to choose properly internal di-
ameter of the tube to ensure the inner walls
distances from the electrode to min. 5 mm.
In some cases (sticky liquids, liquids with low
dielectric constant) is suitable to mount the
sensor in the knee tube.
Applies to: CLS–23_–10, 11, 12, 20, 21
When installing the sensor in vertical position it can be used
for 2-state (LO-HI) level control between the min. and max.
level. The position of the minimum and maximum level can be
changed by setting the sensor. Fluid changes require new set-
tings of the sensor

Applies to: CLS–23_–20, 21, 30 (for electrode length up to 300 mm)
For electrodes with a length over 300 mm for the detection in non-conductive containers (sensors
in vertical position) must be used the auxiliary electrode (e.g. conductivity probe). The auxiliary
electrode is connected to the sensor housing. Recommended length of the auxiliary electrode
and the distance from the sensor are shown in the picture.
Suitable types of auxiliary electrode probes are e.g. Dinel CNP–18F–30 with M18 thread.

7 . electrical connection
For “A” variant with the xed cable, the individual colour cores of the connecting cable are con-
nected to the respective terminals of the related equipment (supply unit).
For “C” variant with the connector, the cable can be supplied with the sensor (length 2 or 5 m), tted
with the pressed connector socket or dismountable connector socket without the cable (see acces-
sories). In this case the cable is connected to the inside pins of the socket according to Fig. 10.
The sensor with related equipment is interconnected by a suitable three-core (P variation) or two-
core (S and R variations) cable. The length of the cable for the Xi and XiT variations must be
selected with respect to the maximum permitted parameters (usually inductance and capacity) of
the outside intrinsically safe circuit of supply units (NSSU, NDSU, NLCU). If using a dismountable
connector socket, the outside diameter of the cable is a maximum of 6 mm
Sensors CLS–23 are equipped with protection against over-voltages and current overload. The capacity
loads and low resistance (bulb) are evaluated by sensors with output type „P“ and „S“ as short circuit.
Sensors with output type „R“ are designed for interconnect to intrinsically safe supply units.
In case of strong ambient electromagnetic interference, paralleling of conductors with power distribu-
tion, or for the distribution to distance over 30 m, we recommend to use shielded cable.

it is necessary to check that the input is galvanically separated from the network side
and that they are tted with a lter suppressing the conforming interference (terminals
+ and – oscillate together towards the ground potential), or the interference is removed
in another manner.

8 . sensor settings
The setting is done by placing magnetic pen MP–8 to sensitive
spot Mlocated on the front of the sensor. Short time attaching
(up to 2 sec.) of the magnetic pen to the sensitive spot M
makes the sensor open. Long time attaching (at least 4 sec.) of
the pen when the level is changed, denes closed state of the
sensor. In this way is set the sensitivity for the measured medi-
um and switching modes SO (normally open) or SC (normally
closed).
Sensitive spot
FACTORY DEFAULT SETTINGS:
Types CLS–23_–10; –20; –30 are set to detect mineral oil, CLS–23_–11; –12; –21 to detect water.
The mode O is set (sensor closes when immersed).
When the level is low (the container is empty), attach the magnetic pen
MP–8 to the sensitive spot
M
for long time (min. 4 sec.). When the level
is high (the container is full), attach the magnetic pen MP–8 to the sensitive
spot
M
for short time (max. 2 sec.). .
When the level is low (the container is empty), attach the magnetic pen
MP–8 to the sensitive spot M for short time (max. 2 sec.). When the
level is high (the container is full), attach the magnetic pen MP–8 to the
sensitive spot M for long time (min. 4 sec.).

Indicator Function
Orange LED
Continuous light – Sensor is closed (switched ON)
Dark – Sensor is open (switched OFF)
Rapid ashing (period 0.2 s) – Unrecognized upper and lower limits or setting mistake
Slow ashing (period 0.8 s) – Short circuit at sensor output
Sensors of type CLS–23E are produced without signaling indicator LED. For control of correct
settings it is necessary to interconnect the sensor to related evaluation unit or load.
In the case of the vertical mounting for detection of non-conductive liquids by sensors CLS–23_–20;
–30 and for detection of conductive and non-conductive liquids by sensors CLS–23_–21 it neces-
sary to set limits ON and OFF when electrode of the sensor is immersed to medium.

For security reasons, we recommend to set the mode O (normally open, sensor closes when immersed)
for minimum level detection. Any failure of the sensor or wiring is equally apparent as the emergency
level state. Analogously – for the maximum level detection is recommended to set the mode C (normally
closed, sensor opens when immersed).

Sensor for each ash of the LED switches its output on for approx. 3 ms. This period is sufciently
short to avoid unwanted switching of relay contacts. For binary inputs, we recommend to set the
lter so as not to respond to pulses shorter than 3 ms.
