1.1 Identification of warning notes
1.2 Qualification of users
The use of products described in this user manual is oriented exclusively to:
– Qualified personnel who plan and design safety equipment for machines and systems
and are familiar with regulations governing occupational safety and accident
prevention.
– Qualified personnel who install and operate safety equipment in machines and
systems.
Qualified personnel Qualified personnel are people who, because of their education, experience, and
instruction and their knowledge of relevant standards, regulations, accident prevention, and
service conditions, have been authorized by those responsible for the safety of the system
to carry out any required operations and who are able to recognize and avoid any possible
dangers.
Requirements Knowledge of the following topics is required:
– Handling of safety components
– Applicable EMC regulations
– Applicable regulations governing occupational safety and accident prevention
This symbol indicates hazards that could lead to personal injury.
There are three signal words indicating the severity of a potential injury.
DANGER
Indicates a hazard with a high risk level. If this hazardous situation is not
avoided, it will result in death or serious injury.
WARNING
Indicates a hazard with a medium risk level. If this hazardous situation is not
avoided, it could result in death or serious injury.
CAUTION
Indicates a hazard with a low risk level. If this hazardous situation is not avoided,
it could result in minor or moderate injury.
This symbol together with the NOTE signal word warns the reader of actions
that might cause property damage or a malfunction.
Here you will find additional information or detailed sources of information.

1.3 Field of application of the product
Only use the safety relay module in accordance with the area of application described in this
section.
1.3.1 Intended use
PSR-MM35 is a safety relay module for sensorless speed monitoring on 3- and 1-phase
motors. PSR-MM35 detects and monitors a minimum speed, a maximum speed, or a speed
range.
Safety functions The safety relay module can perform various safety functions:
– Monitoring of a minimum speed
– Monitoring of a maximum speed
– Monitoring of a speed range
Possible signal
generators
An external signal generator does not need to be connected. The safety relay module is
connected parallel to the motor phases.
Safe shutdown The safety relay module safely interrupts circuits.
 See “Safe state” on page 26.
Safety functions in
accordance with
EN 61800-5-2
With the appropriate wiring and suitable additional components (sensors and actuators),
the safety relay module supports the following safety functions in accordance with
EN 61800-5-2:
– STO (safe torque off)
– SLS (safe limited speed)
– SSM (safe speed monitor)
– SSR (safe speed range)
Achievable safety
integrity
Within a system, the PSR-MM35 safety relay module can be used to achieve the following
safety integrity depending on the conditions of use:
– Up to SIL 3 in accordance with IEC 61508 and EN 62061
– Up to Cat. 4/PL e in accordance with EN ISO 13849
To ensure that the safety relay module is able to perform its safety-related tasks within the
system, integrate the safety relay module into the execution process in a correct and failsafe
manner.
Configuration software The safety relay module is configured using the PSRmotion configuration software.
 See “Configuration and startup” on page 32.
DANGER: The technology is not suitable for every application
–You must ensure, on an application-specific basis, that motion is
stopped when the motor is shut down (STO). Applications in which
motion continues or is accelerated when the motor is shut down (STO),
e.g., suspended loads, are not suitable for sensorless measurement
technology.
–The frequency measurement process will not detect a mechanically
blocked motor or overloaded motor.

Technical data and
environmental conditions
Only use the device in accordance with the defined technical data and environmental
conditions.
 See “Technical data” on page 68.
Application examples The safety relay module is used for the following applications, for example:
– Use in safety circuits in accordance with EN 60204 Part 1
– Applications for the safe shutdown of electrical loads, e.g., contactors or valves
1.3.2 Foreseeable misuse

1.4 Safety notes
1.4.1 General safety notes
Documentation
Safety of personnel and
property
The safety of personnel and property can only be assured if the safety relay module is used
correctly.
 See “Intended use” on page 7.
Startup, mounting, and
modifications
Startup, mounting, modifications, and upgrades may only be carried out by qualified
personnel.
Defective devices The devices may be damaged following an error. Correct operation can no longer be
ensured.
• In the event of an error, replace the device.
Do not open the housing Only the manufacturer or their authorized representative may perform the following
activities. Otherwise, the warranty is invalidated.
– Repairs to the device
– Opening the housing
Decommissioning and
disposal
• Dispose of the device in accordance with environmental regulations.
• Make sure that the device can never be reused.
WARNING: Serious risks due to improper use
Depending on the application, improper use of the safety relay module
may pose serious risks for the user.

1.4.2 Electrical safety
Electrical connection Electrical connection may only be performed by qualified personnel.
Mismatching and polarity
reversal of connections
• Take measures to prevent mismatching, polarity reversal, and manipulation of
connections.
PELV power supply Insulate all electrical connections from the mains using suitable measures.
• Observe the requirements of EN 60204-1, Section 6.4.
• Only use power supply units with safe isolation and SELV/PELV.
• Use the same power source for all devices that are electrically connected to the safety
relay module.
• Make sure that the output voltage of the power supply does not exceed 32 V, even in
the event of an error.
Ground connection • Use the same ground for all devices that are electrically connected to the safety relay
module.
Fuse protection for the
power supply
• Protect the power supply with a suitable external fuse.
• Make sure that the power supply unit is able to supply four times the nominal current
of the external fuse. This ensures safe tripping in the event of an error.
Direct / indirect contact • Protection against direct and indirect contact in accordance with VDE 0100 Part 410
must be ensured for all components connected to the system.
In the event of an error, parasitic voltages must not occur (single-fault tolerance).
Do not remove protective
covers
During operation, parts of the electrical switching devices may carry hazardous voltages.
• Protective covers must not be removed when operating electrical switching devices.
WARNING: Loss of safety function and hazardous shock currents
Incorrect installation can result in the loss of the safety function as well as
hazardous shock currents. Depending on the application, there may be
serious risks for the user.
• Observe the notes on electrical safety.
• Observe the warning instructions provided elsewhere in this document.
• Plan the devices used and their installation in the system according to the
specific requirements.
• Recheck plants and systems that have been retrofitted with the safety relay
module.
