1 Introduction
1.1 Intended Use
Level switches are used to monitor the fill level and temperature in fluid systems.
Level switches must not be used in highly flammable or corrosive liquids.
The medium must not contain particles, particularly metallic particles, to prevent deposits on the float or between the float and
switching tube. If necessary, filter the medium.
Please note the technical data in the appendix for the specific intended use, existing material combinations, as well as temperature limits.
WARNING
All device models are solely intended for industrial applications. They are

not safety com-
The measuring tube is located inside the tank. The reed-contact is located inside the measuring tube.
Simply put, the reed-contact works the same as a regular resistance potentiometer. The reed-contact consists of a number of
reed switches along with resistors connected in series. The total length of the chain varies by the path being monitored.
If a magnet inside a float trips the reed switch, a resistance signal proportional to the position of the float will be output. When
the float changes positions, resistances are more or less activated and the resistance signal altered based on the position of the
float. The resistance signal passes through a transformer yet and is analysed by the display unit.
1.2.2 Temperature monitor
Temperature is monitored via temperature sensor (Pt100) inside the sensor tube. Depending on the version, there are several
switching outputs combined with one analogue output (4 - 20mA). The temperature is shown in the display.
Please note the technical data in the appendix.
1.3 Design types
The level switch is equipped with different switching and analogue outputs based on the configuration. The outputs are freely
programmable.
The level switch can be equipped with the following options:
OV
G1

2.2 General hazard warnings
The equipment must be installed by a professional familiar with the safety requirements and risks.
Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent
malfunctions and avoid personal injuries and property damage.
The operator of the system must ensure:
– Safety notices and operating instructions are available and observed,
– The respective national accident prevention regulations are observed,
– The permissible data and operational conditions are maintained,
– Safety guards are used and mandatory maintenance is performed,
– Legal regulations are observed during disposal.
Maintenance, Repair
Please note during maintenance and repairs:
– Repairs to the unit must be performed by Bühler authorised personnel.
– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.
– Always use genuine spare parts.
Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.
The method for cleaning the devices must be adapted to the IP protection class of the devices. Do not use cleaners which could
damage the device materials.
DANGER Toxic, acidic gases/liquids

DANGER Electric voltage
Risk of electric shock
a) Always disconnect the unit from the mains before performing work.
b) Secure the equipment from accidental restarting.
c) The equipment may only be installed, maintained and put into operation by instruc-
ted, competent personnel.
d) Always observe the applicable safety regulations for the operating site.
DANGER Toxic, acidic gases/liquids
Protect yourself from toxic, corrosive gasses/liquids when performing any type of work.
Wear appropriate protective equipment.
4.1 Installation
The level switch comes fully assembled and can be mounted to the tank using the screw-in thread. Please be sure the float can
move freely and to leave enough space between the tank wall and add-ons.
After removing the float, where applicable, be sure the magnet inside the float is above the fluid level. This can easily be verified
with a piece of iron to determine the magnet position inside the float.
DANGER Electric voltage
Risk of electric shock
When connecting devices, please note the maximum voltages and currents currents (see
technical data) and use the correct wire cross-sections and circuit breakers.
When selecting the connection lines, also note the maximum operating temperatures of
the devices.
Installation in special areas of application:
If the device will be installed outdoors or in wet areas, the maximum operating voltage
is max. 16 V DC effective or 35 V DC.
The flange-mounted display units can be swivelled vertically by approx. 270° so they are easier to read. Please note the built-in
swivel stop. You will notice more resistance when reaching the stop. Turning it beyond this stop may damage the display unit.
4.2 Electrical connections
Electricity is supplied via plug connectors. Please refer to the appendix for installation dimensions, nominal voltage and plug
configuration.
The temperature switching outputs are PNP transistors (see illustration):
Note:
When measuring the switching output with high-load measuring device inputs or when used as a frequency output, the
load must be set to 10 kΩ between the output and earth (GND) to avoid faulty measurements.

5.6.6 Fill level scaling
The display range is scaled between the highest and lowest float position. This scaling will also affect the display accuracy and

Here, NO contact (Hno) means the PNP switching output is closed above switching point SPx and opens
below switching point rPx.
Here, NC contact (Hnc) means the PNP switching output is open above switching point SPx and closes below switching point rPx.
Also see the explanation in the drawing below.

2 LED 2 - red LED 2 - red LED 2 - red
3 LED 3 - yellow LED 3 - yellow
4 LED 4 - red LED 4 - red
5 LED 5 - yellow
6 LED 6 - red
In the factory setting the LED indicates the physical status of the PNP switching output (switching output closed – LED on).
The logical indicator function may need to be different from the physical signal on the switching output. You can therefore also
reverse this indication with this menu (switching output open – LED on).
Example:
You have 2 switching outputs for the temperature, configured as:
Switching output 1:
–
temperature is higher than the desired range. So this LED lighting up indicates an “Error” status.
Switching output 2:
–
temperature. So in this case the LED would light up if the status is okay.
The table shows an example with the factory setting and with inverted status function for LED3. The switching points are
defined as:
SP3 = 70 °C, rP3 = 65 °C
SP4 = 80 °C, rP4 = 75 °C

Here you can reverse the LED status function for a contact: the LED lights up if the contact is open, so below the minimum temperature, and the LED lighting up again indicates an “Error” status.
The options are:
LED = output;
the LED lights up when the PNP switching output
is closed.
the LED lights up when the PNP switching output
LED = -output;
is open.
