Liquipoint FTW33 Basic safety instructions
Endress+Hauser 7
2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Are authorized by the plant owner/operator.
‣Are familiar with federal/national regulations.
‣Before starting work, read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the
application).
‣Follow instructions and comply with basic conditions.
The operating personnel must fulfill the following requirements:
‣Are instructed and authorized according to the requirements of the task by the facility's
owner-operator.
‣Follow the instructions in this manual.
2.2 Designated use
Application and media
The device described in these instructions may only be used as a point level switch for
liquids and foams.
To ensure that the measuring device remains in proper condition for the operating time:
‣Use the device only for media to which the process-wetted materials are sufficiently
resistant.
‣Observe the limit values in "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
‣For special fluids and media used for cleaning, the manufacturer is happy to provide
assistance in verifying the corrosion resistance of fluid-wetted materials, but disclaims
any warranty or liability.
Residual risks
Due to heat transfer from the process as well as power dissipation within the electronics,
the temperature of the electronics housing and the assemblies contained therein may rise
to 80 °C (176 °F) during operation. When in operation, the sensor may reach a
temperature close to the medium temperature.
Danger of burns from contact with surfaces!
‣In the event of elevated fluid temperatures, ensure protection against contact to
prevent burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
For welding work on the piping:
‣Do not ground the welding unit via the device.

Basic safety instructions Liquipoint FTW33
8 Endress+Hauser
If working on and with the device with wet hands:

Repair
To ensure continued operational safety and reliability,
‣Carry out repairs on the device only if they are expressly permitted.
‣Observe federal/national regulations pertaining to repair of an electrical device.
‣Use original spare parts and accessories from the manufacturer only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the
hazardous area (e.g. explosion protection, pressure vessel safety):
‣Based on the nameplate, check whether the ordered device is permitted for the
intended use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an
integral part of these Instructions.

Liquipoint FTW33 Electrical connection
Endress+Hauser 15
6 Electrical connection
6.1 Connection conditions
The measuring device has two modes of operation:
• Maximum point level detection (MAX): e. g. for overfill prevention
The device keeps the electrical switch closed as long as the sensor is not yet covered by
liquid or the measured value is within the process window.
• Minimum point level detection (MIN): e. g. to protect pumps from dry running.
The device keeps the electrical switch closed as long as the sensor is covered by liquid or
the measured value is outside the process window.
Choosing the "MAX"/"MIN" mode of operation ensures that the device switches in a safe
manner even in the event of an alarm condition, e. g. if the power supply line is
disconnected. The electronic switch opens if the point level is reached, if a fault occurs or if
the power fails (quiescent current principle).
• IO-Link: Communication on pin 4; switch mode on pin 2.
• SIO mode: If there is no communication, the device switches to the SIO mode =
standard IO mode.
The functions configured in the factory for the MAX and MIN modes can be changed
via IO-Link:
HNO/HNC hysteresis
6.2 Supply voltage
SIO mode
10 to 30 VDC
IO-Link mode
18 to 30 VDC
IO-Link communication is guaranteed only if the supply voltage is at least 18 V.
6.3 Connecting the device
LWARNING
Risk of injury from the uncontrolled activation of processes!
‣Switch off the supply voltage before connecting the device.
‣Make sure that downstream processes are not started unintentionally.
LWARNING
Electrical safety is compromised by an incorrect connection!
‣In accordance with IEC/EN61010 a separate circuit breaker must be provided for the
device.
‣Voltage source: Non-hazardous contact voltage or Class 2 circuit (North America).
‣The device must be operated with a fine-wire fuse 500 mA (slow-blow).
‣Protective circuits against reverse polarity are integrated.

Function monitoring
When both outputs are connected, the MIN and MAX outputs assume opposite states
(XOR) when the device is operating fault-free. In the event of an alarm condition or a cable
break, both outputs are de-energized. This means that function monitoring is possible in
addition to level monitoring. The behavior of the switch outputs can be configured via IO-
Link.

data. It also provides the option of configuring the device while in operation.
Physical layer, the devices supports the following features:
• IO-Link specification: version 1.1
• IO-Link Smart Sensor Profile 2nd Edition
• SIO mode: Yes
• Speed: COM2; 38.4 kBaud
• Minimum cycle time: TBD
• Process data width: 16 bit
• IO-Link data storage: Yes
• Block configuration: Yes
• Device operational: The device is operational 4 s after the supply voltage has been
