6 Fault Diagnosis
6.2 No Laser Beam
If no laser beam is emitted, please check the following:
1. Is the connecting cable between the controller and the sensor head
installed correctly ?
2. Are the jacks on the connecting cable screwed in securely ?
OFV-303/-353 3. Is the L
ED
LASER on the back of the sensor head lit up after switching the
controller on ?
If the L
ED
is not lit up, it can be assumed that there is a a fault with the
mains power supply of the controller. Disconnect the mains plug and
check the fuses on the back of the controller. Note that there are two
active fuses which can both lead to failure.
4. Is the beam shutter on the back of the sensor head in position ON ?
5. After approximately 20 minutes operation, does the housing of the sensor
head feel warm to the touch as normal, indicating that the laser is
operating ?
OFV-511/-512 6. Is the L
ED
LASER STANDBY on the front of the sensor head lit up after
switching the controller on ?
If the L
ED
is not lit up, it can be assumed that there is a a fault with the
mains power supply of the controller. Disconnect the mains plug and
check the fuses on the back of the controller. Note that there are two
active fuses which can both lead to failure.
7. Is the beam shutter key LASER on the front of the sensor head pressed
once after switching the controller on ?
The L
ED
LASER ON lights up when the beam shutter key LASER is
once pressed and thus the laser beam is emitted. At the same time the
L
ED
LASER STANDBY goes out. Pressing the beam shutter key LASER
a second time the beam shutter is closed, at the same time the L
ED
LASER ON goes out and the L
ED
LASER STANDBY lights up again.
8. Is a break of the optical fiber cable visible ?
