Fault Analysis / Troubleshooting 

Various indicators are available on the Sync Module 8024GPS for representation of the system 
status  and  problem  analysis.  This  status  information  can  also  be  used  to monitor  the  clock 
system by means of a higher level management systems. 

 

4.1  

Fault Scenarios 

This chapter describes various fault scenarios for initial analysis of the problem by the user. It 
also provides assistance in describing the fault when contacting the 

hopf

 support team. 

4.1.1   Complete Failure 

Description 

•

 

The status LED’s on the front panel are off 

Cause / Solution

 

•

 

Equipment is switched off 

•

 

Power supply has failed 

•

 

Power supply unit is defective 

4.1.2   No GPS Reception / No Synchronization 

Description 

•

 

SY

xx is not displayed on the status display of the time tab in the 

hmc

 software   

•

 

The status LED’s on the front panel do not signal any 

SY

xx status 

Cause / Solution

 

•

 

System was not initialized correctly or initialization was incomplete 

The following describes various effects and their possible causes in the case of a non-
synchronizing system: 

Case 1:

 

Effect:   No satellite appears on tab GPS of 

hmc

 software after first installation and 

00

 is displayed under 

In View

. 

Possible faults: 

*  The antenna cable is too long 
*  An incorrect type of cable was used for the antenna cable length 
*  The antenna cable is faulty 
*  The antenna cable is not connected 
*  The antenna is faulty 
*  The indirect lightning protector is faulty
