8. TROUBLESHOOTING 

 

 

WARNING – ELECTRICAL SHOCK HAZARD 

The operations outlined in this section are to be performed by 

qualified maintenance personnel only! 

8.1. REFERENCE DRAWINGS 

There are several illustrations throughout this manual that can be used for reference 

when performing some  of the  troubleshooting  activities. The flow diagram is 

located in Section 3.6 for additional reference if needed. 

8.2. TROUBLESHOOTING USING FRONT PANEL STATUS LED AND 

STATUS OUTPUTS 

 

Figure 8-1. Display and Control Panel 

The  status  LED  on the front  panel  reflects  the current  operating  status of  the 

monitor and indicates fault conditions. See Section 3.4.2 for more information on 

the Status Outputs and Table 8-1 for additional information. 
The  status  details  and  outputs  are categorized  into  Critical and Non-Critical 

warnings.  Critical  warnings  are  those that would normally require immediately 

removing the monitor from service and repairing it. Non-critical warnings are those 

that indicate some maintenance would be useful, but not immediately required.  If 

the front panel LED indicates a status issue, details can be viewed in the STATUS
