7.4 IEEE Error Messages
[1301,"Interlock is open"]
Reason: Attempt to switch on laser while interlock loop is open. Refer to Connecting Interlock and
Status Display
[1302,"Open circuit"]
Reason: Connection to the laser interrupted or laser forward voltage higher than compliance
voltage.
[1303,"Over temperature"]
Reason: Over Temperature Protection was tripped. The module is overheated and cannot be
switched on. Wait until the module has cooled down.
[1304,"Internal power failure"]
Reason: Severe hardware error. Contact Thorlabs .
[1305,"No calibrating of sensor during TEC on"]
Reason: The sensor cannot be calibrated while the TEC output is switched on.
[1306,"No calibrating of PD during laser on in constant power mode"]
Reason: The monitor diode cannot be calibrated (for constant power mode) while laser output is
switched on.
[1307,"No setting of ILD during constant power mode"]
Reason: The set value for I
LD
(laser current) cannot be changed in CP (constant power) mode
[1308,"No setting of IMD in constant current mode"]
Reason: The set value for I
PD
(monitor photo diode current) or P
LD
(laser output power) cannot
be changed in CC (constant current) mode.
[1309,"No LD polarity change during laser on"]
Reason: The polarity of the laser diode cannot be changed while the laser output is switched on.
[1310,"No PD polarity change during laser on"]
Reason: The polarity of the monitor diode cannot be changed while the laser output is switched
on.
[1311,"No mode change during laser on"]
Reason: The operating mode CC or CP cannot be changed while the laser output is switched on.
[1312,"Wrong or no sensor"]
Reason: Attempt to switch on the TEC controller, while no sensor is connected or wrong sensor is
selected.
