3. General Description
3.1 Working principle of the level switch
The media acts as a virtual capacitor from the sensor tip to the metal shaft or the welding part.
An electrode inside the sensor tip builds a capacitor together with the surroundings. The medium with its dielectric
constant (DC value) is defining the capacitance value. A resonance circuit is created in combination with a coil in the
sensor head. Switching signal tripping is according to the measured resonance frequency and the programmed
trigger thresholds.
Alfa Laval level switch TE67O is designed for level detection in tanks and dry-run protection of pumps by empty pipe
monitoring. It detects liquid, pasty or oily media, but also solid-bulk materials like flour or plastic granulate. The TE67O
is capable of media differentiation by distinguishing the specific properties, such as oil, water, foam and liquid.
Reliable performance is assured in any mounting position (from top, bottom or side). Depending on the desired process
connection, different mounting options are available. Corresponding mounting aids and adaptors for conventional pro-
cess connections are available as an accessory.
The switching output is available as Normally Open (NO) and Normally Closed (NC) can be selected by re-connecting
the electronics (please see page 12)
The Alfa Laval level switch TE67O is default configured to cover the major part of potential applications. Where custom-
er-specific configuration is required because of difficult media (e. g. foamy or adhering), the interface programming tool
Alfa Laval Instrument Programmer (9614448501) allows for easy parameterization of the optimum switching point by
convenient teach-in functionality. The measured data can be visualized on a PC for further parameter adjustment, for
example time constant of a damping function and inverted switching output logic.
3.3 Recycling information:
 Unpacking
 Packing material consists of plastic and cardboard boxes.
 Cardboard boxes can be reused, recycled or used for energy recovery.
 Plastics should be recycled or burnt at a licensed waste incineration plant.
 Maintenance
 During maintenance seals and O-ring should be replaced (only on clamp connections).
 All metal parts should be sent for material recycling.
 Worn out or defective electronic parts should be sent to a licensed handler for material recycling.
 Oil and all non metal wear parts must be taken care of in agreement with local regulations
 Scrapping
 At end of use, the equipment shall be recycled according to relevant, local regulations. Beside the equipment
itself, any hazardous residues from the process liquid must be considered and dealt with in a proper manner.
When in doubt, or in the absence of local regulations, please contact the local Alfa Laval sales company.

5. Installation
5.1 Mechanical Installation
The TE67O has several possibilities for mechanical mounting into the process.
It can de delivered with both hygienic clamp connections and non-hygienic versions.
Warning:
Install only the Alfa Laval level switch when the tank or pipe is depressurized and currentless.
Installation:
 Carefully remove the level switch from the package.
 Only use a suitable gasket or O-ring depending on the media
 If the level switch has a G1/2” connection, there is no sealing
 Tighten the process connection or clamp ring only with recommended torque (15 … 20 Nm for G1/2”)
 Make sure that the level switch is placed so the electrical connector or cable gland is facing
downwards to avoid water ingress
Mounting of the 3-A approved CFF welding adaptor :
For the TE67O0Dx1111xx to be compliant to 3-A it must be installed in the welding adaptor
TE67N000000019.
The TE67N000000019 welding adaptor can be fitted on tanks and on pipes.
O-ring TE67N000000019
Mounting with Clamp DN38/DN51 (ISO2852):
The TE67O is available with either a DN38 or a DN51 clamp connection.
To ensure a correct measurement it is important to follow the guidelines of the installation.
When using a ISO2852 ferrule,it is important that the gasket is placed correctly to ensure a tight connection.
Follow these guidelines to ensure a good connection:
 Always position the ferrule in a self draining position
 On a vertical pipe, make sure that the ferrule is angled at least 5 degrees.
 All weldings should be grinded to Ra = 0,8 µm
These standard Alfa Laval ferrules are recomended for the TE67O:

It is important that the installation comply to 3-A regulations which means that:
 Only 3-A approved welding adaptor is to be used (TE67N000000019)
 The inspection hole should be visible and drained
 Mount the adapter in a self-drained position/angle
 The 3-A mark or the arrow shall be placed upwards
 Welding should be grinded to Ra=0.8
 Welding according to appropriate 3-A standard
TE67N000000019 is also available with (these are not included in the 3-A authorization):
Electropolishing: TE67N000000020

5. Installation
5.2 General Installation Guidelines
After installation
 Check the leak tightness of the sleeve/ferrule.
 Check the tightness of glands or M12 plugs.
 Check the tightness of the cover
When installed in tanks with a ISO2852 ferrule it is important
only to install it on vertical surfaces and with an angle of 5°
which makes it self draining
When installed in the bottom of tanks it is recommended to use
the CFF process connection (TE67N000000019) or the Unique
Flexbody connection to get a flush mounting without any dead
legs.
Tank Installation:
Fitted
incorrect
Cannot be
drained
WARNING
Avoid dead legs:
Dead legs are areas around process connections which, because of misplacement of the connection, is very
hard to clean. Welding adaptors must always be placed in a way which makes them self drained and easy to
clean. This is done by keeping an angle of at least 5 degrees

6. Setup
6.1 Manual Teach-In
Make sure that power is on before Teach-In.
For best Teach-In it is important the product is fixed in the final application.
During Teach-In mode the light intensity of the LED will increase, please protect your eyes.
Ste
p To do LED Result
2 With no media present connect
”Teach-In” to - VDC shortly
Light on for 2 second and then
flash
Register ”empty” state. Pls. See note
3 With media present connect
”Teach-In” to - VDC shortly Light on for 2 seconds Register ”full” state, stores the value and returns to Normal operation with new setting
1 Connect terminal ”Teach-In” to
- VDC (T1 or T2) for 3,5 second Flash 1 time per second Ready for Teach-in
NOTE:
If the media is sticky, foamy, powdery or in other ways leaving parts of the media at the sensor tip this situation has to be
established also during the Teach-In process. Otherwise a faulty calibration can be the result.
If Teach-In for some reason do not succeed, the level Switch TE67O will enter “Error State” and automatically reload factory
settings . The factory settings can always be reloaded by connecting the terminal “Teach-In” to -VDC for more than 6.5 sec-
onds.
A reloaded factory settings will be confirmed by pulsing light intensity 3 times.
Error state Flushing
3 × short and 1 × long
Can normally be fixed by powering off and on and remake the Teach-In.
Alternatively remake the Teach-In configuration by use of the

8. Troubleshooting
No electrical output from the sensor
In case of no electrical signal from the sensor please follow this checklist for identifying the problem.
 Loosen and remove the cover
 Measure if there is 10-35 VDC on the two supply terminals to make sure that there is power to the sensor
 Check if wiring is according to the scedule on p. 12
If all of these points is checked, and the sensor still have an error, the level switch needs to be returned to Alfa Laval for
repair.
