1 Introduction
1.1 Intended Use
The contamination indicator BCI24 is used to monitor the filter capacity in oil circuits. A microprocessor-controlled pressure
transmitter monitors the pressure drop above the filter element which increases as the filter contamination increases.
WARNING
All device models are solely intended for industrial applications. They are not safety com-
ponents. The devices must not be used if failure or malfunction thereof jeopardises the
safety and health of persons.
Use in explosive areas is prohibited.

WARNING
Signal word for a hazardous situation with medium risk, possibly resulting in severe injuries or death if not
avoided.
CAUTION
Signal word for a hazardous situation with low risk, resulting in damaged to the device or the property or
minor or medium injuries if not avoided.
NOTICE
Signal word for important information to the product.
Warning signs
These instructions use the following warning signs:
Warns of a general hazard General information
Voltage warning Unplug from mains
High pressure warning
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,
– compliance with national installation regulations.

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.

4 Installation and connection
DANGER Electric voltage
Risk of electric shock
a) De-energise the system.
b) The equipment may only be installed, maintained and put into operation by instruc-
ted, competent personnel.
c) 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 equipment must be installed by a professional familiar with the safety requirements and risks.
DANGER Electric voltage
Risk of electric shock
When connecting devices, please note the maximum voltages and currents (see tech-
nical 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.
WARNING System pressurised
De-pressurize the system prior to assembly.
The contamination indicator BCI24 screw directly into the line filter. Tighten the BCI24 to a torque of approx. 25Nm. Be sure the
seal (copper ring, O-ring or NBR sealing ring, varies by version) is in perfect condition.
NOTICE
The top and bottom of the BCI24 match. Therefore do not use a different top. The system
could otherwise be damage.
However, loosening a locking screw allows turning the top so the cable outlet of the M12
plug connector can be repositioned as needed. Then secure the screw hand-tight!
4.2 Electrical connections
The BCI contamination indicator is powered with +18-30 V direct voltage. The sensor connects with a cable and standard M12
plug-in connectors.

5 Operation and Control
NOTICE
The device must not be operated beyond its specifications.
5.1 Version with analogue and switching outputs
With this version the switching outputs are the primary signals.
To ensure the switching outputs respond, the respective threshold must be overrun for at least 4 seconds. This will avoid the sys-
tem responding too soon if the brief pressure peaks occur.
Switching output 1 is configured as NO contact with increasing pressure drop. This switching output closes at 75% of the set
pressure drop measuring range.
Switching output 2 is configured as NC contact with increasing pressure drop. It opens at 100% of the set pressure drop measur-
ing range.
All switching outputs are reset automatically.
The analog output supplies a 4-20mA current signal proportional to the set pressure drop measuring range.
Attention! For technical/physical reasons the lower 10% of the measuring range are hidden. Within this range the output cur-
rent remains at 4 mA until the release threshold is reached.
5.2 Version with IO-Link interface
This unit is equipped with an IO-Link interface, which require an IO-Link master.
The IO-Link interface allows direct access to process and diagnostics data, and allows configuring the unit during operation.
The IODDs required to configure the unit is available at https://ioddfinder.io-link.comwill appear.
If the IO-Link interface is not being used (no master or only used to parametrise), the BCI24 functions as a regular pressure drop
switch with 2 switching outputs. The standard parameters and switching function of the switching outputs correspond with the
version with current output. However, they can be parametrised via IO-Link master.
