Safety features
The laser is equipped with all required safety features as described in the laser safety standard 60825-1. Disabling any
safety features negate the CE/CDRH compliance of this product. If any part of the delivered equipment is replaced
with a part not supplied by Cobolt or if the equipment is not properly grounded system may not conform to CE / CDRH
compliance standards listed in section 14 : Compliance (CDRH models only). Disabling any of the safety features
nullifies the CE marking and violates the laser safety standard.
Remote Interlock Connector
The remote interlock connector is a connector which permits the connection of external controls placed apart from
other components of the laser product. When the terminals of the connector are open-circuited, emission is
interrupted, and no radiation will be accessible. The remote interlock connector permits easy addition of an external
interlock in laser installation. See section Remote Interlock Connector for a detailed description of the remote
interlock circuit and operation.
Manual Shutter (Beam Stop)
The laser head is equipped with a manual shutter, which functions as the beam stop, capable of preventing human
access to laser radiation. The aperture location and the open and close positions of the shutter are indicated on the
top surface of the laser head.
Key Control
The CDRH compliant model comes with a key-switch on the controller or the key control box which must be connected
for the laser to operate. When the key is in the OFF position, the laser is prevented from emitting. The key must be
actively turned to the ON position each time the laser is powered on. When the key is removed from the system laser
radiation is not accessible.
Laser Radiation Emission Warning
The controller and the key control box incorporate information LEDs which display whether power is connected, the
laser is on, or a fault has occurred. The “ON” LED is illuminated whenever the device is emitting or could emit light.
See section 3.4 for details on the controller. The emission warning indicators are also visible in the Cobolt Monitor™
software, see section 9 for details on the control software.
Equipment Safety
Always install all power supplies used in the laser system to properly grounded power outlets. The laser head and
controller must be mounted on a common ground plane, such as an optical table. Cobolt lasers contain a laser diode
which is sensitive to electrostatic discharge (ESD).
