E. Control/supply cabinet
The control/supply cabinet is located behind the machine. It consists of:
1
Access door for electrical components (drives, IPC...)
2
Access door for laser, chiller, ups, and Safety override switch*
3
Access door for electrical management parts (circuit-breaker, power contactors...)
4
Connection panel (see section "Connection panel" on page 29)
*The safety override switch allows to select the operating mode of the system (normal mode, or service mode). When the
safety override switch is turned on, the red light located near the switch is switched on, and the following components can
be turned on or controlled even when the oxygen level is not at the required level: laser, lens cleaner blower and process
lter valves. The switch position can be viewed on the user interface (see section "Machine Status menu" on page 54).
Caution : the safety override switch must be used only by 3DSystems authorized and certied
maintenance personnel to perform servicing tasks.
• The laser rack generates the infrared laser beam. It is tted with an emergency stop and a locking key. It switches on
automatically when the machine is powered up.
• The chiller stabilizes laser temperature via a hydraulic circuit. The cooling circuit is tted with a particle lter. Cleaning
the lter regularly is recommended. Consult the Preventive maintenance section for the recommended maintenance
interval.
