LOGS
1.
Time
: time at which the log occurred.
2.
Date
: date at which the log occurred.
3.
Name
: unique log name
4.
Primary value
: optional.
5.
Secondary value
: optional.
Every event is logged in the device FLASH memory. From the log menu the user can view their history. Use the UP/DOWN KEYS to navigate between logs, 2
logs are visible simultaneously on the LCD. Logs are of 3 different kinds:
info
,
alarms
and
events
. All
info
and
alarms
have an associated Modbus field with
the current status (0 if inactive or 1 if active). For
info
and
alarms
a log is generated at each status transaction. In case of active alarm the front LED and the
buzzer turn ON.
ALARMS
TYPE
LCD NAME
DESCRIPTION
Battery disconnected
Bat. discon.
Active when no battery is detected by LDD960-UU.
Battery Ri too high
Bat Ri too high
Active when measured battery internal resistance exceed the alarm threshold
Battery under temperature
Bat under temp.
Active when the battery measured temperature (using the optional external sensor) is under the
threshold specified in “
Battery min. temperature
” field. If active the battery charged is disabled.
Battery over temperature
Bat over temp.
Active when the battery measured temperature (using the optional external sensor) exceed the
threshold specified in “
Battery max. temperature
” field. If active the battery charged is disabled.
Battery lifetime elapsed
Bat lifetime
Active when the actual calculated battery
lifetime exceeds the threshold specified in “
Battery
lifetime
” field.
Battery charge failure
Bat charge fail
Active when LDD960-UU could not charge the battery correctly. When active, the battery charger is
disabled. Disconnect the battery to reset the alarm.
Battery SoC < 25%
Bat SoC 25%
Active when the battery State of Charge is under 25% of the nominal full charge capacity.
Battery over discharge current
Bat over dis. I
Active when the measured battery discharge current reaches the threshold specified in “
Battery
max. discharge current”
field.
Battery low
Bat low
Active when the measured battery voltage is
under the threshold specified in “
Battery low voltage
”
field.
Battery deep discharged
Bat deep disch.
Active when the battery measured voltage is under the threshold specified in “Battery deep discharge
voltage” field.
Backup
Backup
Active when the system is in backup.
Input under voltage
In under volt.
Active when the measured input voltage is under 90% of the “
Nominal output voltage
” field.
Input over voltage
In over volt.
Active when the measured input voltage exceeds 120% of the “
Nominal output voltage
” field.
Output under voltage
Out under volt.
Active when the measured output voltage is under 90% of the “
Nominal output voltage
” field.
Output over voltage
Out over volt.
Active when the measured output voltage exceeds 120% of the “
Nominal output voltage
” field.
Output overload
Out overload
Active when the measured output current reaches the threshold specified in “
Max. output current
”
field.
Input over current
In over cur.
Active when the measured input current reaches the
threshold specified in “
Max. input current
” field.
Auxiliary output overload
Aux overload
Active when an excessive load is detected on the auxiliary output.
External temperature sensor error
Ext. T error
Active when the external temperature sensor is not connected while it’s use is mandatory like in
NiMh battery charging.
Backup time left < 25%
Bkp left 25%
Active when the system is in backup and the maximal backup time is less than the “
Max. backup
time
” filed.
Warning over temperature
Warn. over T
Active when the internal temperature is high. If the temperature increases more the device may
switch OFF.
Error over temperature
Error over T
Active when the internal temperature is too high. To prevent damage the device switches OFF.
