OWNERS MANUAL | Cobolt 08-01 Series | D0141-K SEPTEMBER 2020
Fiber Pigtailed Option
All safety recommendations in section 2.1 are also valid for the Cobolt 06-01 series fiber pigtailed laser heads.
Additionally, heat generated from absorption of laser radiation by particles on the fiber end may increase the
probability of ignition hazards in certain environments. Always clean the fiber end before turning on the laser. In
systems where the beam is exposed, fiber end must be mounted < 2 m from the emission warning LED on the key
control box. It is advised to perform a risk assessment for the facility and equipment prior to using the laser. In the
case of integration into a larger system, laser safety compliance must be evaluated in the end product.
Safety features
The laser is equipped with all required safety features as described in the laser safety standard IEC 60825-1. 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 0. Disabling any of the safety features
nullifies the CE marking and violates the laser safety standard. If the laser does not function, do not attempt to open
any of the units, or the warranty will be voided.
CAUTION
Use of controls or adjustments or performance of any procedures other than those
specified herein may result in exposure to hazardous radiation.
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 5.8
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. For 06-03 fiber pigtailed lasers, the fiber end cap is considered the manual shutter.
Key Control
The CDRH compliant model comes with a key control box which must be connected for the laser to operate. When
the key is in the OFF position, the diode 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 key control box, which is part of the CDRH compliant models, incorporates LEDs which indicate the status of the
Laser. The “ON” LED is illuminated whenever the device is emitting or could emit light. See section
4.3 for details on
the key control box. The emission warning indicators are also visible in the Cobolt Monitor™ software, see section
for details on the control software.
