2 Safety
For mounting, operating and testing, this document as well as all applicable national and international stan-
dards, regulations, rules and directives must be observed. Relevant and supplied documents must be ob-
served, printed out and handed to affected persons.
ÄBefore working with the safety relay, completely read and understand the documents applicable to your
task.
In particular, the following national and international legal regulations apply for the start-up, technical in-
spections and work with safety relays:
• Machinery directive 2006/42/EC
• Low voltage directive 2014/35/EU
• EMC directive 2014/30/EU
• Use of work equipment directive 89/655/EEC supplemented by directive 95/63EC
• OSHA 1910 Subpart O
• Safety regulations
• Accident-prevention regulations and safety rules
• Ordinance on Industrial Safety and Health and employment protection act
• Product Safety Law (ProdSG and 9. ProdSV)
NOTICE
For safety-related information you may also contact local authorities (e.g., industrial inspec-
torate, employer's liability insurance association, labor inspectorate, occupational safety and
health authority).
2.1 Intended use and foreseeable misuse
DANGER
Electrically live systems pose a risk of electric shock!
ÄMake certain that, during all conversions, maintenance work and inspections, the system is
securely shut down and protected against being restarted.
ÄOnly have work on the electrical system and electronics performed by a competent person
(see chapter 2.2 "Necessary competencies").
2.1.1 Intended use
WARNING
A running machine may result in serious injury!
ÄMake certain that the safety relay is correctly connected and that the protective function of
the protective device is ensured.
ÄMake certain that, during all conversions, maintenance work and inspections, the system is
securely shut down and protected against being restarted.
Only if the safety relay is correctly connected and correctly started up is the protective function of the pro-
tective device ensured. To prevent misuse and resulting dangers, the following must be observed:
• These operating instructions are included in the documentation of the system on which the protective
device is mounted and are available to the operating personnel at all times.
• The safety relay is used as a safety monitoring device in combination with one or more safety sensors
for safeguarding danger zones or points of operation on machines and systems.
• The safety relay may only be used after it has been selected in accordance with the respectively appli-
cable instructions and relevant standards, rules and regulations regarding labor protection and safety at
work, and after it has been installed on the machine, connected, commissioned, and checked by a
competent person (see chapter 2.2 "Necessary competencies").
• The safety relay must only be connected and commissioned in accordance with its specifications (tech-
nical data, environmental conditions, etc.).
Safety
Leuze electronic MSI-MD-FBX 8
• The acknowledgment unit for unlocking the start/restart interlock must be located outside of the danger
zone.
• The entire danger zone must be visible from the installation site of the acknowledgment unit.
• When selecting the safety relay it must be ensured that its safety-related capability meets or exceeds
the required performance level PLr ascertained in the risk assessment (see chapter 13 "Technical
data").
• The machine or system control must be electrically influenceable so that a switch command sent by the
safety relay results in the immediate shutdown of the dangerous movement.
• The construction of the safety relay must not be altered. When manipulating the safety relay, the pro-
tective function is no longer guaranteed. Manipulating the safety relay also voids all warranty claims
against the manufacturer of the safety relay.
• The safety relay must be inspected regularly by a competent person to ensure proper integration and
mounting (see chapter 2.2 "Necessary competencies").
• The safety relay must be exchanged after a maximum of 20years. Repairs or the exchange of wear
parts do not extend the mission time.
2.1.2 Foreseeable misuse
Any use other than that defined under the “Approved purpose” or which goes beyond that use is consid-
ered improper use.
Alone, the safety relay is not a complete protective device. It is not suitable for use in the following cases:
• Applications in explosive or easily flammable atmospheres
• On machines or systems with long stopping times
2.2 Necessary competencies
The safety relay may only be configured, installed, connected, commissioned, serviced and tested in its re-
spective application by persons who are suitably qualified for the given task. General prerequisites for suit-
ably qualified persons:
• They have a suitable technical education.
• They are familiar with the relevant parts of the operating instructions for the safety relay and the operat-
ing instructions for the machine.
Task-specific minimum requirements for suitably qualified persons:
Configuration
Specialist knowledge and experience in the selection and use of protective devices on machines as well as
the application of technical rules and the locally valid regulations on labor protection, safety at work and
safety technology.
Mounting
Specialist knowledge and experience needed for the safe and correct installation and alignment of the
safety relay with regard to the respective machine.
Electrical installation
Specialist knowledge and experience needed for the safe and correct electrical connection as well as safe
integration of the safety relay in the safety-related control system.
Operation and maintenance
Specialist knowledge and experience needed for the regular inspection and cleaning of the safety relay –
following instruction by the person responsible.
Servicing
Specialist knowledge and experience in the mounting, electrical installation and the operation and mainte-
nance of the safety relay in accordance with the requirements listed above.
Safety
Leuze electronic MSI-MD-FBX 9
Commissioning and testing
• Experience and specialist knowledge in the rules and regulations of labor protection, safety at work and
safety technology that are necessary for being able to assess the safety of the machine and the use of
the safety relay, including experience with and knowledge of the measuring equipment necessary for
performing this work.
• In addition, a task related to the subject matter is performed in a timely manner and knowledge is kept
up to date through continuous further training ‑ Competent person in terms of the German Betrieb-
ssicherheitsverordnung (Ordinance on Industrial Safety and Health) or other national legal regulations.
2.3 Responsibility for safety
Manufacturer and operating company must ensure that the machine and implemented safety relay function
properly and that all affected persons are adequately informed and trained.
The type and content of all imparted information must not lead to unsafe actions by users.
The manufacturer of the machine is responsible for:
• Safe machine construction
• Safe implementation of the safety relay, verified by the initial test performed by a competent person
(see chapter 2.2 "Necessary competencies")
• Imparting all relevant information to the operating company
• Adhering to all regulations and directives for the safe commissioning of the machine
The operator of the machine is responsible for:
• Instructing the operator
• Maintaining the safe operation of the machine
• Adhering to all regulations and directives for labor protection and safety at work
• Periodic testing by a competent person (see chapter 2.2 "Necessary competencies")

The MSI-MD-FB muting controller is used as a safety-relevant link between an active opto-electronic pro-
tective device (AOPD) and the machine control. The muting controller enables muting through intentional
and temporary suppression of the protective function of the safety sensor, e.g., if objects are to be trans-
ported through the protective field.
The muting controller is mounted on machine parts or on a device column.
