OWNERS MANUAL | Cobolt 04-01 Series | D0105-I October 2022
Operating Instructions
As standard, all lasers are delivered with the Controller set in Auto-start mode. As soon as power is supplied to the
Controller the temperature control elements are operating to reach set-point values and the laser emission will start,
unless the key-switch is enabled (CDRH model).
Installation start-up operation
1.
Mount the laser head on a suitable heat sink (see Section 3.6).
2.
Ensure that the remote interlock jumper is connected.
3.
Connect the laser head to the Controller with the Cable and fasten screws at both ends.
4.
Connect the 12 VDC power supply to the mains outlet and then to the Controller.
5.
The laser now goes through the following auto-start sequence:
•
Temperature stabilization (1-2 min). Status LEDs: POW flashing, then POW goes on.
•
Turn key switch to start the laser. Status LEDs: ON goes on (CDRH model only)
•
The laser starts (light is emitted) in a constant warm-up current constant for 60 sec.
Status LEDs: ON goes on.
•
The laser locks to pre-set output power (<2 min) and operates according to specifications.
Status LEDs: LOCK goes on.
If the power does not match the power as stated on the test sheet see Section 11 : Service for more information.
Shutdown procedure operation
1.
Turn the key switch to OFF first (CDRH models only).
2.
Disconnect PSU from mains outlet.
3.
Disconnect Controller from PSU.
Operating Modes
There are two operating modes: constant power and constant current. The default mode for Cobolt 04-01 series lasers
when shipped is constant power. In constant power mode the power is monitored on an internal photodiode, and this
is used to regulate the current to maintain a constant power level. In constant current mode the laser runs at a set
current level.
