Sensors with TIIS approval (CLS50D-TA****, CLS50-T***)
Sensors with TIIS approval may only be used in a Zone 1 (2G) environment.
The following also applies for all the sensors listed
• Compliance with the specified ambient and medium temperature ranges is a prerequisite
for safe use.
• The sensor must be connected and operated in accordance with the Operating Instructions
of the sensor and of the transmitter to be connected. All sensor operating data must be
observed.
• Avoid electrostatic charge. Metal process connections must be electrostatically connected (R
≤ 1 MΩ).
• Non-metal process connections must be protected against electrostatic charge.
• In order to avoid electrostatic charge clean the sensor with a damp cloth only.
• Full compliance with regulations for electrical systems in hazardous locations
(EN60079-14) is mandatory when using the devices and sensors.
• Ensure correct installation to maintain the housing protection type. (Use original seal. Fit
cable entry properly. Tighten nut).
• The degree of protection only applies when the flange is mounted.
CLS50 only
In the CLS50 sensor, the internal sensor circuits are connected with the shielded wire of
the supply cable. When installing the CM42 or CLM153 transmitter, the shielding of the
sensor cable must be connected to functional ground as prescribed. As a result, the
intrinsically safe sensor circuits of CLS50 are also connected to ground. Therefore, the
power supply of the transmitter must be galvanically isolated and connected to ground.
The CM42 and CLM153 transmitters already have secure internal galvanic isolation and
therefore safely separate the sensor circuit from the other circuits.

‣
opening of the sensor in the direction of medium flow.
The sensor head must be completely immersed in the medium.
1 Sensor orientation, dimensions in mm (in)
1 Direction of medium flow

by multiplying by the installation factor. The value of the installation factor depends on the
diameter and the conductivity of the pipe nozzle as well as the sensor's distance to the wall.
The installation factor f can be disregarded (f = 1.00) if the distance to the wall is sufficient (a
> 15 mm (0.59"), from DN 80). If the distance to the wall is smaller, the installation factor
increases for electrically insulating pipes (f > 1) and decreases for electrically conductive pipes
(f < 1). It can be measured using calibration solutions, or a close approximation determined
from the following diagram.
2 Relationship between installation factor f and wall distance
1 Electrically conductive pipe wall
2 Electrically insulating pipe wall
4.1.3 Air set
CLS50D
The digital sensor has already been adjusted at the factory. Onsite compensation is not
required.

5.2.2 Cable extension
The sensor is supplied with a fixed cable. The cable between the sensor and transmitter can be
extended using the CYK11 (CLS50D) or CLK6 (CLS50) measuring cable (does not apply for use
in a hazardous environment).
9 CYK11 for extension of CLS50D
Total cable length (max.): 100 m (330 ft)
A0017984
10 CLK6 for extension of CLS50
Total cable length (max.): 55 m (180 ft)
A0024937
CLS50 only:
The residual coupling of the sensor increases when the fixed cable is extended.
5.3 Ensuring the degree of protection
Only the mechanical and electrical connections which are described in these instructions and
which are necessary for the required, designated use, may be carried out on the device
delivered.
Exercise care when carrying out the work.
‣
Otherwise, the individual types of protection (Ingress Protection (IP), electrical safety, EMC
interference immunity) agreed for this product can no longer be guaranteed due, for example
to covers being left off or cable (ends) that are loose or insufficiently secured.
5.4 Post-connection check
Device condition and specifications Action
Are the sensor, assembly, or cables free from damage on the
outside?
Electrical connection Action
Are the mounted cables strain-relieved and not twisted?
Is a sufficient length of the cable cores stripped, and are the
cores positioned in the terminal correctly?
Are all the screw terminals properly tightened?
Are all cable entries mounted, tightened and leak-tight? In the case of lateral cable entries:
Are all cable entries installed downwards or mounted laterally?
30 Endress+Hauser
Perform a visual inspection.
‣
Untwist the cables.
‣
Pull gently to check they are seated correctly.
‣
Tighten the screw terminals.
‣
Point cable loops downward so that water can
‣
drip off.
Indumax CLS50D/CLS50 Commissioning
6 Commissioning
Prior to initial commissioning, ensure that:
• The sensor is correctly installed
• The electrical connection is correct
If using an assembly with automatic cleaning function:
Check that the cleaning medium (water or air, for example) is connected correctly.
‣
WARNING
L
Escaping process medium
Risk of injury from high pressure, high temperatures or chemical hazards!
Before applying pressure to an assembly with cleaning system, ensure that the system has
‣
been connected correctly.
If you cannot reliably establish the correct connection, do not install the assembly in the
‣
process.
At the transmitter, enter all the settings specific to the parameters and measuring point.
‣
The measuring point is then ready to measure.
Following commissioning, the sensor must be serviced at regular intervals, as only then
can reliable measurement be guaranteed.
