Safety Switches - 3D Systems FIGURE 4 MODULAR User Manual

Safety Symbols and Definitions
The following are safety symbols that are common to 3D Systems guides. Some or all of these symbols may appear in this guide
and/or in other Figure 4 Modular documentation.
CAUTION: Indicates the possibility of loss of data or damage to equipment.
WARNING: INDICATES THE POSSIBILITY OF INJURY OR DEATH TO PERSONNEL.
ELECTRICAL SHOCK HAZARD: High voltage electricity is accessible in the vicinity of this sign or behind the access
panel. High voltage can cause severe burns or death, as well as fires. Access panels are for service only and should
be opened only by certified service personnel or trained maintenance personnel.
CAUTION: Possible hazardous optical radiation emitted from the product. Do not stare at operating lamp. May be
harmful to the eyes.
HARMFUL IRRITANT WARNING: Indicates that skin or eye irritation could result while exposed to a chemical
composition
EYE PROTECTION: Indicates the need for eye protection.
WEAR GLOVES: Wear the appropriate gloves when required. For example, when touching surfaces that may contain
or have been exposed to materials, wear nitrile gloves. Heat gloves are necessary when touching surfaces that may
be hot to ensure burns don't occur.
PINCH POINT: Indicates a pinch point hazard that could cause personal injury.
Personal Injury Warning: Failure to avoid the pneumatic tension arms may result in personal injury. Avoid the
tension arm areas at all times.
HOT SURFACE HAZARD: A hot surface is accessible in the vicinity of this sign or behind the access panel. Avoid
contact. Hot surfaces can cause burn injury or fire. Allow surface to cool before touching. Access panels are for
service only and should be opened only by certified service personnel or trained maintenance personnel.
Note: A note signifies important information but not information of a critical content.
Alarms and Warnings
• If you hear an alarm, or if you see an error, alarm, or warning message on either the Figure 4 Modular Controller or Printer
display: clear the alarm, error, or warning message before resuming operation.
• Displayed error, alarm, or warning messages can result from unsafe practices, such as defeating a safety switch.

2.1 Safety Switches

There are four safety switches on the Printer: upper-chamber door-closed sensor, catch tray sensor, platform-presence sensor,
and resin-tray presence sensor. Photos and effects of tripping these sensors are listed below.
