Hydra-Pulse HYC 230 • SDI-12
Principle of operation
Hydra-Pulse HYC 230 is a radar sensor for non-contact, continuous
level measurement. It is suitable for liquids and solids in practically all
industries.
The device is designed for connection to data loggers with SDI-12
interface, making it particularly suitable for battery-powered applica-
tions requiring low power consumption.
The Hydra-Pulse HYC 230 can be operated at any data logger with
SDI-12 interface. The sensors are powered via the +12 V line of the
three-wire connection cable.
The instrument emits a continuous, frequency-modulated radar signal
throughitsantenna.Theemittedsignalisreflectedbythemedium
andreceivedbytheantennaasanechowithmodifiedfrequency.The
frequency change is proportional to the distance and is converted
into the level.
Adjustment
The optionally integrated Bluetooth module enables a wireless
adjust-ment of Hydra-Pulse HYC 230 via standard adjustment
devices:
•Smartphone/tablet (iOS or Android operating system)
•PC/notebook with Bluetooth USB adapter (Windows operating
system)

permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
•Active measuring component
•Processtting
•Process seal
Process conditions in particular are:
•Process pressure
•Process temperature
•Chemical properties of the medium
•Abrasionandmechanicalinuences
Mounting versions
For the wall mounting, a mounting bracket with opening for thread G1
is recommended.The mounting of the device in the bracket is carried

Radar sensors for level measurement emit electromagnetic waves.
The polarization is the direction of the electrical component of these
waves.
The position of the polarisation is in the middle of the type label on the
instrument.

Note:
When the device is rotated, the direction of polarization changes and
hencetheinuenceofthefalseechoonthemeasuredvalue.Please
keep this in mind when mounting or making changes later.
Mount the device at a position that is at least 200 mm (7.874 in) away
from a wall or structural parts (see illustrations above).
If you cannot maintain this distance, you should carry out a false
signal suppression during setup.This applies particularly if buildup
on the wall or structural parts is to be expected. In such cases, we
recommend repeating the false signal suppression at a later date with
existing buildup.

Access protection
Hydra-Pulse HYC 230 • SDI-12
Access protection
Bluetooth radio interface
Devices with a Bluetooth radio interface are protected against un-
wanted access from outside.This means that only authorized persons
can receive measured and status values and change device settings
via this interface.
A Bluetooth access code is required to establish Bluetooth com-
munication via the adjustment tool (smartphone/tablet/notebook).
This code must be entered once when Bluetooth communication is
establishedforthersttimeintheadjustmenttool.Itisthenstoredin
the adjustment tool and does not have to be entered again.
The Bluetooth access code is individual for each device. It is printed
on the device housing and is also supplied with the device in the infor-
mation sheet " PINs and Codes". It can be changed by the user after
therstconnectionhasbeenestablished.IftheBluetoothaccess
code has not been entered correctly, a new entry can only be made
after a waiting period has elapsed.The waiting time increases with
each additional incorrect entry.
The emergency Bluetooth access code enables Bluetooth communi-
cation to be established in the event that the Bluetooth access code
is no longer known. It can't be changed.The emergency Bluetooth
access code can be found in information sheet " Access protection".
If this document is lost, the emergency Bluetooth access code can
be retrieved from your personal contact person after legitimation.
The storage and transmission of Bluetooth access codes is always
encrypted (SHA 256 algorithm).
Protection of the parameterization
The settings (parameters) of the device can be protected against un-
wanted changes. The parameter protection is deactivated on delivery,
all settings can be made.
To protect the parameterization, the device can be locked by the user
with the aid of a freely selectable device code. The settings (param-
eters) can then only be read out, but not changed.The device code
is also stored in the adjustment tool. However, unlike the Bluetooth
access code, it must be re-entered for each unlock.When using the
adjustment app or DTM, the stored device code is then suggested to
the user for unlocking.
The emergency device code allows unlocking the device in case the
device code is no longer known. It can't be changed. The emergency
device code can also be found on the supplied information sheet " Ac-
cess protection". If this document is lost, the emergency device code
can be retrieved from your personal contact person after legitimation.
The storage and transmission of the device codes is always encrypt-
ed (SHA 256 algorithm).

Maintenance
If the device is used properly, no special maintenance is required in
normal operation.
Insomeapplications,buildupontheantennasystemcaninuence
the measuring result. Depending on the sensor and application, take
measures to avoid heavy soiling of the antenna system. If necessary,
clean the antenna system in certain intervals.
The cleaning helps that the type label and markings on the instrument
are visible.
Take note of the following:
•Use only cleaning agents which do not corrode the housings, type
label and seals
•Use only cleaning methods corresponding to the housing protec-
tion rating
Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
Thedeviceoersmaximumreliability.Nevertheless,faultscanoccur
during operation.These may be caused by the following, e.g.:
•Sensor
•Process
•Voltage supply
•Signal processing
Therstmeasuresare:
•Evaluation of fault messages
•Checking the output signal
•Treatment of measurement errors
A smartphone/tablet with the adjustment app or a PC/notebook with
thesoftwarePACTwareandthesuitableDTMoeryoufurthercom-
prehensive diagnostic possibilities. In many cases, the causes can be
determined in this way and the faults eliminated.
Depending on the reason for the fault and the measures taken, the
