Information
The safety-related characteristic data of the PNOZ s30 and all other devices
that are used must be taken into account when calculating the safety level.
We recommend that you use the PAScal software tool to calculate the safe-
ty function's SIL/PL values.
The safety assessments below only consider the subsystems Sensor and
PNOZ s30. The Actuator subsystem depends on the application and must
also be considered in the overall assessment.
Information on the safety-related characteristic data for the subsystems Sensor and PNOZ
s30
Example:
Sensor subsystem PNOZ s30 subsystem
Category MTTFd DC Operating mode PFH [1/h]
2 Manufactur-
er-specific
90 % Monitoring
1 encoder
3,28E-08
The values for Category and DC can be set for the sensor subsystem, bearing in mind the
restrictions stated in the respective chapter. The MTTFd value must be stated by the device
manufacturer.
Assuming that all faults are dangerous, MTTF = MTTFd can be set.
The characteristic value MTTF is a property of the sensor, which may only be stated by the
manufacturer.
Forced dynamisation:
When monitoring sensors with square output signals (TTL, HTL) or safe sensors, the axis
must be moved within 8 hours so that the signal changes on all the connected tracks.
Key:
SRP/CS = Safety-related part of a control system (EN 13849-1, Tab. 2)
Safety functions
The following safe monitoring functions are available:
} Standstill
} Position
} Speed
} Speed range
} Direction
} Monitoring for broken shearpins
The safety functions of the PNOZ s30 are monitoring functions, whereby a safe output sig-
nal is used to show if defined limit values are exceeded.
