Safety instructions

WARNING
Depending on the application, improper use of the CPU can pose serious
risks to the user
When handling the CPU, observe all safety instructions listed in this chapter.
WARNING
Avoid danger - outputs can be set
−
Take appropriate measures to ensure that there is no danger from your
plant/machine.
−
In the "DEBUG-RUN" state, variables can be overwritten. These are then
also transmitted to the FSoE output devices and output.
−
Do not automatically acknowledge an operator acknowledge request from
the user program. The acknowledgment must be triggered by a conscious
user action.
−
If you reintegrate passivated FSoE participants, safety-related outputs can
be set! Take appropriate measures to ensure that your plant/machine is
not at risk when passivated FSoE participants are reintegrated.
WARNING
Loss of electrical safety and safety function when using unsuitable power
supplies
The CPU is designed exclusively for operation with protective extra-low
voltage (PELV) according to EN 60204-1. Only protective extra-low voltages
in accordance with the specified standard may be used for supply. The fol-
lowing applies to the network (FSoE and System SLIO) and the I/O devices
used within it:
−
Only use power supplies that comply with EN 61204, with safe isolation
with PELV voltage according to IEC 61010-2-201 (PELV). In these, a short
circuit between the primary and secondary sides is excluded.
NOTICE
Observe supporting checklists
The checklists listed in the appendix serve to support planning, assembly and
electrical installation, commissioning and parametrization as well as validation
of the safety CPU and the FSoE system.
NOTICE
Device identification / number of safety devices
−
Note that each F address must be unique within a network and overlaps
are not permitted.
NOTICE
'Watchdog' must not exceed TI/TO
−
The value specified in iCube Engineer under 'Watchdog' must not exceed
TI/TO
