System Indicators / Fault Analysis / Troubleshooting
The System 6842 GPS Slim Line (1U) provides a variety of indicators for presenting the
System status and for problem analysis. This status information can also be used for
monitoring the clock system by means of a supervisory management system.
The System 6842 monitors itself and the installed Function Boards for faults. These may be,
for example, reception failures or Function Board errors.
Faults that arise are displayed or transmitted via various elements.
7.1 Status and Fault Indicators
The System status und faults arising can be identified with the aid of the following elements:
7.1.1 Status LEDs
The System has Status LEDs on both the front and rear sides (see
Chapter 1.1.4 Status
LEDs
).
7.1.1.1 "Power ON" LED
The "Power ON" LED lights up as soon as the System is provided with power and switched
on. This LED goes out if the operating voltage fails, the System is switched off or the power
supply unit is faulty.
7.1.1.2 "Sync. Status" LEDs
The "Sync. Status ON" LED lights up as soon as the System attains "Sync" status (r, R on
the display). A change from ON (green) to OFF (red) signals the loss of synchronization. The
action of the LEDs can be influenced by the "Status Change After" setting (see
Chapter
4.1.4.1 Delayed Sync. Status Change
).
7.1.2 LCD-Display
A variety of status information can be read and fault analysis carried out with the aid of the
LCD-Display.
7.1.2.1 System Status on the Display
The synchronization status can be read directly on the display (see
Chapter 3.3.2 Standard
Display with Valid Time
).
7.1.2.2 Number of Satellites
An analysis of reception can be carried out with the display of satellite values. It can be seen
whether the GPS receiver is receiving satellites and, if so, their reception values (see
Chapter 4.1.2.4 Satellite Values (GPS)
).
7.1.2.3 Position Display
Depending on the position entered manually by the user, it can be identified from the position
display whether the GPS receiver calculated the position correctly and was / is therefore
synchronous (see
Chapter 4.1.2.3 Position
).
