System Status
Clicking on the
System Status
area of the menu bar provides specific module information such as
the part number, model number, and serial number, see Figure 8.2-1. Additionally, a Module Fault
Status indication is shown. The Module Fault Status indication is shown in this window as well as in
the LED located on the top side of the module. The Module Fault Status is a logical OR of several
alarms which are LOS, laser bias current exceeds the maximum current limit, laser pump
temperature out of valid operating range, laser driver current limit reached, and laser driver
junction temperature limit reached. If any of these conditions occur, the Module Fault Status
indication will alarm (Red). The four conditions that are not related to LOS indicate a problem with
the laser and will cause an automatic laser shutdown (ALS). To clear an ALS condition, the user
must click the Reset Fault button which is located on the bottom row of the Control Functions as
shown in Figure 8.2-2. If the fault condition will not clear, please contact us (TPC) since a hardware
failure may have occurred.
