Interlock Description
Light source
remote jack (1) In case your laboratory safety specifications require extra measures such as
a door or foot interlocks to operate laser equipment, you can attach such a
switch to a connector on the back of the ARC2 controller. If this switch is
open, the laser power will be interrupted. Since such requirements are rare,
the ARC2 controller ships with a shorted connector, keeping this switch per-
manently closed. Removing the connector will shut the laser off. Call Asylum
Research for an additional connector to which you can attach your own cus-
tomized interlock system.
Front panel laser
power key switch
(2) The laser is generally turned on and off by means of the key on the front of
the ARC2 controller. The key is captive when the laser is on, but can be
removed in the ‘off’ position.
Scanner laser inter-
lock (3) When the scanner module is removed there is significantly more space
under the objec- tive lens to insert objects which might reflect the laser light
in the direction of the user. To prevent this, the laser power circuit is broken
as soon as the scanner cable is disconnected, a necessary step for scanner
removal.
Laser module dual
magnetic switch
interlock (4,5) The laser module (or collimated laser source) includes magnetically activated
switches that cut the laser power unless the module is inside its cradle. This
prevents the module from emitting collimated light when it is outside the
confines of the instrument. The presence of strong magnetic fields can over-
ride the interlock operation. For additional safety always turn the laser key
on the front of the ARC2 controller to the off position and/or turn off the
controller power.
Note: A red LED on the front of the laser module indicates whether col-
limated light is being emitted. Never look into the module if this LED is
on. An additional precaution is to simply never look into the module’s
collimating lens.
Light source module
When you remove the light source module it is possible to tamper with safety overrides in such a
way that collimated light shines out of the module. As a safety precaution, never look directly into
the module while its power cable is attached (power cable not shown in the following image).
