Faults in the primary switchgear are indicated only with “Fault” and a consecutive fault
number. Detailed information on the sequence of events during a fault is contained in
the block “Fault annunciations”.
Fault
annunciations
Block 82 Here the annunciations of the last eight faults can be read out. These are sorted from
the newest to the oldest in a subordinate level of block 82. When a ninth fault arrives,
the system deletes the data of the oldest one. Each of the eight fault buffer can store
up to 30 annunciations. If more events are issued, the oldest are overwritten.
As long as the date and time of the device have not been set, the date and time dis-
played are the relative date and time since the last startup of the processor system.
Next, the fault events are displayed in the chronological order of their detection, with
a relative time referred to the moment at which the fault started.
Pressing the key brings you from block
)$8/7$1181&
( ) to the fault
annunciations, where you can call up successively all fault annunciations using the
and keys.
To move from the selected fault annunciation to the fault annunciation buffer, press
the
key.
Just like the operational annunciations, the fault annunciations are stored in lists. Use
the
and keys to scroll though the lists.
Measured values
Block 84 Measured values for the differential and restraint current can be displayed in block 84.
Values are shown in percent of the nominal values. A prerequisite for correct display
is that the nominal data have been correctly set in block 00.
Pressing the key brings you from block
0($69$/8(6
( ) to the mea-
sured values, which can now be called up successively using the and keys.
The values are updated during the read-out. When scrolling within the block with the
or key, the updated values are displayed.
