Capacitive proximity switch CPS–24 is intended for detection of proximity or motion of solid
objects. It is suitable for indication of the liquid level through non-conductive walls of vessels or on
non-conductive gauge-pipes. It is excellent for liquid leakage detection in collection pits or directly
on oors. The sensor state is indicated by LED. The sensitivity is adjustable by a trimmer located
under a cover screw on the rear side. The design and housing materials of CPS allow the use in
complicated environments (harsh, dusty, explosive, aggressive) as well as in clean environments
(medical technology).
To ensure maximum safety of control processes, we have dened the following safety instructions
and information. Each instruction is labelled with the appropriate pictogram.
This symbol informs you about particularly important instructions for installation and operation of
equipment or dangerous situations that may occur during the installation and operation. Not observing
these instructions may cause disturbance, damage or destruction of equipment or may cause injury.
This symbol indicates particularly important characteristics of the device.
This symbol indicates helpful additional information.
Alloperations described inthis instruction manualhave to becarried out bytrained personnel
or by an accredited person only. Warranty and post warranty service must be exclusively
carried out by the manufacturer.
Improper use, installation or set-up of the sensor can lead to crashes in the application.
The manufacturer is not responsible for improper use, loss of work caused by either direct

Sensing of bulky-solid materials in metal con-
tainers or tanks. The position of the sensor is
set so that it is approximately 10 mm from the
inner wall of a storage tank.
Sensor is used for sensing leakages in an
interception tank. Leakage indication in de-
tention pits and boxes with “Plate holder

Sensor application for level gauges and eye
sights. The maximum wall thickness in both
cases is up to 10 mm. A glass or plastic level
gauge (tube) must have an outer diameter of
at least 20 mm. The face of the sensor must
be touching the wall.
Sensing of moving objects on conveyor. The
distance of the sensor from moving objects is
set according to their size, shape and material
composition (approx. 1 to 8 mm).
Detection of liquid presence in the inter-wall space of double-walled storage tanks. The sensor is
suspended down into the inter-wall space on its own cable. For this application, we recommend
variant „B“ with an extended cable terminal with the installation variant of a PVC hose for cable
protection.

In the case of vertical mounting in outer areas or in the
case of high mechanical exertion we recommend to in-
stall in Variant “B” protective hose on the cable (see
gure).

Sensor with NPN or PNP output is allowed to lead only by resistive or inductive lead. Positive sup-
ply voltage (+U) is connected to the brown conductor BN (1), negative (0 V) to the blue conductor
BU (3) and the leads (only NPN or PNP type of output) to the black conductor BK (4). The capacity
loads and low resistance loads (bulb) is evaluated by the sensor as short circuit.
The line from CPS-24N to the connecting device is from a suitable three wire (min. 3x0.5 mm2)
cable, in the case of variant CPS-24Xi using a two wire (min. 2x0.5 mm2) cable. In the event that
a disassemblable socket ELWIKA or ELKA 4012 K PG7 are used, the max. outer diameter of the
cable is 6 mm. Connector socket is not part of the sensor.

Electrical connection can only be made when de-energized!
The source of the power voltage must comprise of a stabilised safe low power source with
galvanic separation. In the event that a switch-mode power supply is used, it is essential
that its construction effectively suppresses common mode interference on the secondary
side. In the event that the switch-mode power supply is equipped with a PE safety terminal,
it must be unconditionally grounded! Spark-safe devices (type CPS-24) must be powered
from a spark-safe power source meeting the above-mentioned requirements.

Due to the possible occurrence of an electrostatic charge on the non-conductive parts of
the sensor, it is necessary to ground all sensors intended for use in environments with an
explosion hazard (type CPS-24Xi). This can be performed by grounding el. conductive tanks
or el. conductive tank lids, and in the case of el. non-conductive tanks using and grounding
an auxiliary plate electrode PDE-27.
In the event that the water level meter (sensor) is installed in an outdoor environment at a
distance greater than 20 m from the outdoor switchboard, or from an enclosed building, it
is necessary to supplement the electrical cable leading to the water level meter (sensor)
with suitable overvoltage protection.
In the event of strong ambient electromagnetic interference, paralleling of conductors with
power distribution, or for distribution to distances over 30 m, we recommend using a shielded
cable and grounding the shielding on the side of the power source.
The sensitivity is set by trimmer located under cover screw on the rear side. Clockwise turning
makes the sensitivity lower, reverse direction turning makes the sensitivity higher.

SETTING THE BASE SENSITIVITY:
a) Type CPS-24_-_-_O:
Turn the trimmer to the left until the LED is lit. Then turn slightly to the right until the LED just
turns o. From this point, turn 180° to the right.
b) Type CPS-24_-_-_C:
Turn the trimmer to the left until the LED turns o. Then turn slightly to the right until the LED is
lit. From this point, turn 180° to the right.
After setting the sensitivity, do not forget to properly tighten the trimmer cover screw.
The base sensitivity of the sensor is factory set (sensing distance on the metal surface) 8 mm. The
actual sensitivity (sensing distance) depends on the dielectric properties or where appropriate the
conductivity of the sensed material.
For sensing of materials with a low relative permittivity (plastics), we recommend to individually set
a higher sensitivity, or consult with the manufacturer if necessary.

For minimum level sens-
ing we recommend sen-
sor with normally open
output (NO, PO, RO). It is
for failure safety reasons
– eventual failure of sen-
sor behaves similarly as
an exceeding of the limit
state.
Analogically for maximum
level sensing we recom-
mend normally closed out-
puts (NC, PC, RC).
For leakage indication
we recommend the NC,
PC, RC version too. It is
maximum level sensing
as well, despite the sen-
sor is at the lowest place
in the room.
