2.
After clicking on the scan button, listen for the motor and see if the CR slide moves at
all. If it does not move at all, then the motor controller board may be at fault.
•
open the back of the CR unit (see Section 8.2 for instructions) and locate the
motor controller board on the lower left. The motor has cables directly connected
to the board.
•
look for either a red or green indicator light on the board. It may be covered by
silicone, which can be removed.
•
a green light on the motor controller board indicates that the board is in working
condition, while a red light indicates a faulty board that will need to be replaced.
If the board needs replacement, please contact Technical Support.
3. Check the following:
•
check the fuses on the power distribution board (see Section 8.12 for instructions)
•
check that the laser and eraser lights turn on: With the slide away from the home
position, see if the laser turns on (full beam from top to bottom). The laser beam
must also overlap the trigger board behind the long mirror.
• if the laser does not turn on, check if the galvo mirror oscillates.
•
if the galvo is on and the laser is not, wiggle the cable coming from the laser
body to see if the laser turns on.
•
follow the cable to the laser connector on the PMT board and make sure it is not
loose. Unplug and replug the connector.
Note the slide must be away from the home position fro the laser to turn on.
•
if the galvo does not turn on, check the galvo cables. Wiggle them, then unplug
and replug the connectors.
4.
If the galvo does not turn on, the galvo or PMT board may need to be replaced. If the
galvo turns on the but the laser does not, replace or repair the laser
