8 . Error Codes
When an error occurs, the driver generates an error code. The error code can be
determined by the
GE
command. Furthermore, the error is shown on the display. A
list of error codes and their causes follows:
error code cause
0
no error
1
interlock open
2
laser compliance voltage not
acceptable
or no laser connected
3
internal supply voltage not
acceptable
4
laser temperature sensor open
5
crystal temperature sensor open
6
laser temperature exceeds upper limit
7
laser temperature lower than lower limit
8
laser short-circuit or no laser connected
9
device temperature (
GT
) too high
10
laser temperature exceeds maximum laser temperature (
LTM
)
11 crystal temperature exceeds upper limit
12
crystal temperature lower than lower limit
16
laser current greater than maximum current limit (
LCLM
)
17
current error
18
total power limit exceeded
