Difference to versions before 2.7.0:
-
during the manual mode the automatic control is stopped
-
when you are leaving manual mode, the connected steps will be not disconnected
-
the test-mode which allows switching capacitors when voltage and current are out of range is removed
2.7 DATALOGGER (option
–DM)
2.7.1 SETUP-HISTORY
Setup history gives information about the last 64 settings. It is working as ring-buffer, so the oldest information is over-
written.
Setup history gives information about date and time and type of parameter which is changed. By pushing the
◄►
-key,
you can change to the values. On top line you can see the actual value the bottom line shows the former value of the
modified parameter.
2.7.2 ALARM-HISTORY
Alarm history gives information about the last 64 alarm states. It is working as ring-buffer, so the oldest information is
overwritten. It shows release and reset of alarms.
Alarm history gives information about date and time and type of alarm. By pushing the
►
-key, you can see the reason
of the alarm. On top line you can see the value in the moment when alarm comes, the bottom line shows the threshold
level of alarm. By pushing the
►
-key again, you get information about the current and voltage in the moment of alarm.
2.7.3 Logging of measurements
BLR-CM can log up to 3072 sets of measurements with date and time. The interval can be set from 1 minute to 720
minutes (0=stop logging). Alternatively, there can be use the digital input (3.10) of data-logger to synchronize the log-
interval to other applications. It is working as ring-buffer, so the oldest information is overwritten. To download logged
measurements, please use TTL interface and software “Data_log”. Data can be stored as CSV – file. For analysis of data
you can use common available spreadsheet software.
2.7.4 Logging of system information
BLR-CM can log up to 512 sets of system information with date and time (enough for 1.4 years). It is working as ring-
buffer, so the oldest information is overwritten. This log happens every day at 23:59:59. System information are: kWh,
kvarh, number of switching operations per exit, capacitor size, average PF, average PF of last 24h. This logging is always
active.
To download logged information, please use TTL interface and software “Data_log”.
Data can be stored as CSV – file. For analysis of data you can use common available spreadsheet software.
