Version: 1.8.0
CAUTION
Note on approval according to EN 81-20, EN 81-22 and EN 81-50
• The TwinSAFE components may only be used in machines that have been designed and installed in ac-
cordance with the requirements of the EN 60204-1 standard.
• Provide a surge filter for the supply voltage of the TwinSAFE components against overvoltages. (Reduc-
tion to overvoltage category II)
• EN 81 requires that in the case of devices with internal temperature monitoring, a stop must be reached
in the event of an overtemperature. In this case, passengers must be able to disembark (see EN 81-20
chapter 5.10.4.3, for example). To ensure this, application measures are necessary. The internal termi-
nal temperature of the TwinSAFE components can be read out by the user. There is a direct switch-off at
the maximum permissible temperature of the respective TwinSAFE component (see chapter Tempera-
ture measurement).
The user must select a temperature threshold below the maximum temperature such that a stop can be
reached in all cases before the maximum temperature is reached. Information on the optimum terminal
configuration can be found under Notes on the arrangement of TwinSAFE components and under Exam-
ple configuration for temperature measurement.
• For the use of the TwinSAFE components according to EN 81-22 and EN 81-50, the conditions de-
scribed in the manuals for achieving category 4 according to EN ISO 13849-1:2015
must be
observed.
• The use of TwinSAFE components is limited to indoor applications.
• Basic protection against direct contact must be provided, either by fulfilling protection class IP2X or by
installing the TwinSAFE components in a control cabinet which corresponds at least to protection class
IP54 according to EN 60529.
• The ambient conditions regarding temperature, humidity, heat dissipation, EMC and vibrations, as speci-
fied in the operating instructions under technical data, must be observed.
• The operating conditions in potentially explosive atmospheres (ATEX) are specified in the operating in-
structions.
• The safe state (triggering) of the application must be the de-energized state. The safe state of the Twin-
SAFE components is always the de-energized, switched-off state, and this cannot be changed.
• The service life specified in the operating instructions must be observed.
• If the TwinSAFE component is operated outside the permissible temperature range, it changes to
"Global Shutdown" state.
• The TwinSAFE components must be installed in a control cabinet with protection class IP54 according to
EN 60529, so that the requirement for contamination level 3 according to EN 60664-1 can be reduced to
level 2.
• The TwinSAFE components must be supplied by a SELV/PELV power supply unit with a maximum volt-
age of U
max
<= 36 V
DC
