System Indicators / Fault Analysis / Troubleshooting
The System 6844(RC) 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 sys-
tem by means of a supervisory management system.
The System 6844(RC) monitors itself and the installed Function Boards for System-Bus for
faults. These may be, for example, reception failures or Function Board errors.
Faults that arise are displayed or transmitted via various elements.
9.1
Status and Fault Indicators
The System status und faults arising can be identified with the aid of the following elements:
9.1.1 Status LEDs
The 1U System has Status LEDs on both the front and rear sides (see
Chapter 1.2.3.4 Sta-
9.1.1.1 "Power" LED (1U Systems only)
The "Power" 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 sup-
ply unit is faulty.
9.1.1.2 "Sync. Status" LEDs (1U Systems only)
The "Sync." 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 "SyncOFF Timer" setting (see
Chapter 5.3.6 SyncOFF Tim-
9.1.1.3 LED Power Supply Unit (not for 1U)
The standard power supply unit has an LED that lights up as soon as power is available to
the power supply unit (except 1U).
9.1.2 LCD-Display
A variety of status information can be read and fault analysis carried out with the aid of the
LCD-Display.
9.1.2.1 System Status on the Display
The synchronization status can be read directly on the display (see
Chapter 4.3.2 Standard
9.1.2.2 Number of Satellites (GPS only)
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
Chap-
ter 5.3.1 Satellite Values (GPS only)
