SLS SYSTEM RESPONSE IF AN INTERLOCK FAILS
Safety interlock devices mounted on the SLS
system sense the hazardous operating conditions
below. The SLS system takes the actions listed
when an interlock fails.
Limited Access And Barrier Shielding
SLS equipment frame and enclosure designs limit
access to the following:
Service areas , such as cabinets and enclosures
for electrical power and automation controls. This
prevents accidental exposure to electrical shock
hazards.
Powder areas , such as powder feed hoppers,
storage bins, and transport tubes. This prevents:
✓
burn hazards by minimizing exposure to
heated powder
✓
slip hazards by keeping powder from
dropping on the floor
✓
fire hazards by minimizing airborne dust
cloud formation and potential ignition. See
MSDS for complete hazard details.
