Error Codes
The GE command returns the current error code.
If no error occurred, it is 0.
When an error leads to switching off the laser, GE is set accordingly.
The next time the laser is turned on successfully, GE is reset to 0.
A list of error codes and their causes follows:
| error code | cause |
|---|---|
0 | no error, everything ok |
1 | interlock open |
2 | laser compliance voltage not OK or no laser connected |
3 | internal supply voltage not OK |
4 | laser temperature sensor open |
5 | crystal temperature sensor open |
6 | laser temperature exceeds upper limit (1SLU) |
7 | laser temperature lower than lower limit ( 1SLL) |
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 (2SLU) |
12 | crystal temperature lower than lower limit (2SLL) |
16 | laser current greater than maximum current limit (LCLM |
17 | current error |
18 | total power limit exceeded |
