18 Laser Safety www.ets-lindgren.com
Exposure to any laser radiation during normal operation is not likely because the
EMCenter uses only fiber-coupled lasers. However, for the safety of all
employees, please comply with the following rules:
 When the EMCenter is not in use, power off the unit.
 The remote interlock connection should be connected to an emergency
master disconnect and in series with the room door or fixture
interlocks.
 Connect all fiber cables and install protective covers before switching
on the system. Protective covers are identified by the following label:
 Do not attempt to turn on the EMCenter if the fiber optic cables show
any sign of damage.
Safety Features
To make the EMCenter as safe as possible, the primary safety system of each
plug-in card is designed to work standalone, without any intervention from the
EMCenter. Apart from this, the EMCenter has its own safety interlock system,
which is connected in series with the interlock system of every installed card.
Additionally, the following safety measures are implemented:
 The EMCenter is equipped with a remote interlock system. For
example, this interlock system would prevent inadvertent laser
radiation by preventing someone from entering a shielded room and
stepping on a fiber.
 To prevent accidental activation of the laser, an Acknowledge button
will appear directly after the Laser Start button is pressed. The laser
will start only if this button is pressed within a four-second timeframe.
 A visual Laser On indicator warns the operator of laser activity. The
Laser On LED on the front panel of EMCenter indicates that at least
one laser is active.
