2.2 General dangers
This section provides an overview of all major safety as-
pects for the protection of people and for safe, fault-free
operation. Further task-related safety notices appear in
the sections on transportation, installation, checks before
initial operation, and maintenance.
SCSQ10 safety valves are used to control hazardous
movements in pneumatic safety systems with category
4 control requirements per ISO 13849-1 with performance
level “e”. The safety valves are free of residual pressure and
are dynamically self-monitored.
Silencers shall not impair the operation of the soft start /
quick exhaust valve.
WARNING!
Dangerous if misused!
• Incorrect use of safety values can create
dangerous situations.
• Do not use in explosive areas.
• Provide noise reduction measures.
• Never dismantle safety valves, or remove or
replace individual parts.
The following section lists residual risks which
may be present even if the safety valves are used
correctly.
