The above system is an example using XBC-DN32H about system example (2). Unlike (2) example, 5V
output capacity of XBC-DN32H is maximum 2A, normal configuration is available.
4.5 Data Backup Time
When RTC module is not installed with main unit, data is kept by super capacitor.
The following table shows the data backup time of the main unit,
Type Data backup time Remark
XBC
“S” type
“SU” type
backup by the Capacitor 18 Days
At normal temperature (25℃)
RTC module installed 3 Yeas
XBC
“E” type
backup by the Capacitor 5 Days
RTC module installed 3 Yeas
But charge super capacitor enough while power is on over 30 minute.
In case super capacitor is not charged enough or power is off more than data backup time, latch data is
not kept and warning occurs. At this time, phenomenon and measure are as follows.
(1) Phenomenon
(a) RUN mode
1) In case of Remote Run mode, operation mode changes to Stop mode. In case of Local Run
mode, it operates normally with abnormal data backup warning
2) In case of Stop mode, abnormal data backup warning occurs.
(b) Latch data
1) Latch area 1,2 : all data are cleared into “0”.
2) K area, F area : all data are cleared into “0”.
(2) Measure
(a) In case abnormal data backup warning occurs when turning off and turning on within data backup
time, technical assistance of main unit is necessary. Be careful data backup time is getting shorter at
high temperature.
Notice
Above data backup time can be different according to temperature condition.
