Indicators on the AMB 32 main board
Besides the segment display the AMB 32 Main Board has various LEDs, with the following meaning (see also
•
Flashing point on the left-hand segment display = watchdog display (processor is running)
•
Flashing on the segment display, point and
AL
= Autolearning is running;
•
On the segment display, flashing point on the left, point steady lit on the right = day/night control active (in
X01
–
X03
only);
•
LED ”
WDog
” = watchdog display (processor not running
ASD has triggered a fault);
•
LED
CardOk
= SD memory card present
•
LED
Com
= communication with the SD memory card.
Other output and display possibilities on the segment display include:
•
in switch position
E
= event memory, see Sec. 8.5.3;
•
in switch position
F
= firmware version, see Sec. 7.3.6;
•
Push button “UP” = the set configuration (
A11
to
C31
,
W01
to
W44
,
X01
to
X03
), see Sec. 7.6.1;
•
in switch position
V
= airflow values (volume rate of flow), see Sec. 7.6.1.
8.5.3
SD memory card operation
The SD memory card is automatically detected when the device is switched on and when the card is inserted. From then on it
is monitored. Data logging begins automatically after approx. 10 s.
Warning
•
Only industrial SD memory cards tested and approved by the manufacturer may be used (see Sec. 12.1). The
use of a consumer SD memory card is to be avoided – this can lead to data loss or destruction of the
SD memory card and faults on the ASD.
•
Inserting the SD memory card: Before using the SD memory card, make sure it is blank (file interpretation).
•
Removing the SD memory card: To avoid data loss, log off the SD memory card on the AMB 32 (switch posi-
tion
o00
) before removing (see Sec. 7.3.7).
The SD memory card is inserted with the contact side facing toward the LMB circuit board and pushed into the holder until it
snaps into place. Pressing the SD memory card again releases the locking mechanism and the SD memory card can then be
removed from the holder.
The meaning of the LEDs
CardOk
and
Com
is described Sec. 8.5.2.
8.5.3.1
Data logging on the SD memory card
Smoke level and airflow values
: The smoke level and airflow values as well as the current status of the sampling tube net-
work are written to the SD memory card every second (default, can be changed with ASD
Config
) and saved in
Log-Files
(*.xls file). After 28,800 entries (corresponding to 8 hours with a logging interval of 1 s) a new
Log-File
is automatically gener-
ated. A total of 251
log files
(L000.xls to L250.xls) can be generated for long-term logging. After the last
log file
the oldest one
(L000.xls) is overwritten. The 251
Log-Files
are sufficient to cover 83 days of data logging (with a logging interval of 1 s). The
log files
can be opened in Excel and the data processed with the diagram assistant to create charts.
Events
: All events occurring in the ASD 532 are written to the
Event-Files
(*.aev file). After 64,000 events a new
Event-File
is
created automatically. A total of 10
Event-Files
(E000.aev to E009.aev) can be generated for long-term logging. After the last
Event-File
the oldest one (E000.aev) is overwritten. The 10
Event-Files
are sufficient to log over 640,000 events. The
Event-
Files
can be opened with a text editor. Please refer to Sec. 8.5.3 for the interpretation of the events. There is also the possibil-
ity of importing
Event-Files
using the “ASD
Config
” configuration software and displaying them as real event text.
