Type ME24
1 THE OPERATING INSTRUCTIONS
The operating instructions describe the entire life cycle of the device. Keep these instructions in a location which is
easily accessible to every user and make these instructions available to every new owner of the device.
Important Safety Information.
Read the operating instructions carefully and thoroughly. Study in particular the chapters entitled “2 Authorized
use” and “3 Basic safety instructions”.
▶The operating instructions must be read and understood.
1.1 Symbols
DANGER!
Warns of an immediate danger.
▶Failure to observe the warning will result in a fatal or serious injury.
WARNING!
Warns of a potentially dangerous situation.
▶Failure to observe the warning may result in serious injuries or death.
CAUTION!
Warns of a possible danger.
▶Failure to observe this warning may result in a moderate or minor injury.
NOTE!
Warns of damage to property.
• Failure to observe the warning may result in damage to the device or the equipment.
Indicates important additional information, tips and recommendations.
Refers to information in these operating instructions or in other documentation.
▶Designates instructions for risk prevention.
→Designates a procedure which you must carry out.
Indicates a result.
1.2 Definition of the term “product”
In these instructions, the term „product“ always refers to the I/O module, Type ME24.
English

Authorized use
Type ME24
2 AUTHORIZED USE
Non-authorized use of the Type ME24 may be dangerous to people, nearby equipment, and the
environment.
The I/O module Type ME24 collects, converts and compares physical measurement data from external sensors
or receives switching commands from büS participants via the büS interface. This measurement data or these
switching commands are relayed to external actuators or to büS participants via the büS interface.
▶Use according to the authorized data, operating conditions and conditions of use specified in the contract
documents and operating instructions.
Observe the following when using the product
▶Use the device only in conjunction with third-party devices and components recommended and authorized by
Bürkert.
▶Use only when in perfect condition and always ensure proper storage, transportation, installation and
operation.
▶Use only as intended.
English

Basic safety instructions
Type ME24
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• contingencies and events which may arise during the assembly, operation, and maintenance.
• local safety regulations – the operator is responsible for observing these regulations, also in relation to the instal-
lation personnel.
General hazardous situations.
To prevent injuries:
▶Do not make any internal or external changes on the product and do not subject it to mechanical stress.
▶Secure the system from unintentional actuation.
▶Only trained technicians may perform installation and maintenance work.
▶After an interruption in the power supply, ensure that the process is restarted in a controlled manner.
▶Observe the general rules of technology.
NOTE!
Electrostatic sensitive components or modules.
The product contains electronic components which react sensitively to electrostatic discharge (ESD). Contact
with electrostatically charged persons or objects are hazardous to these components. In the worst case scenario,
they will be destroyed immediately or will fail after start-up.
• Observe the requirements in accordance with EN 61340-5-1 to minimize or avoid the possibility of damage
caused by sudden electrostatic discharge.
• Do not touch electronic components while the supply voltage is switched on.

Description of the device
Type ME24
5 DESCRIPTION OF THE DEVICE
The output module of Type ME24 receives the switching commands of büS participants via the büS interface, pro-
cesses them and relays this information to externally connected actuators.
The input module of Type ME24 receives the physical measurement data from external sensors. The input module
converts and compares this measurement data and communicates the values via the büS interface to büS participants.
The HMIU module Type ME25, in conjunction with the display Type ME21, can be used to configure the basic func-
tions. Alternatively, this can also be carried out via the “Bürkert Communicator”.
5.1 Possible combinations
The I/O module Type ME24 can only be operated within a system in combination with additional modules. For
setting up a system comprising several modules, please contact your Bürkert sales office.
