Below mention, points need to be check to troubleshoot this problem.
1) Check Power input cable connected properly
2) Check Power input cable connected to respective terminal as described in section 14.1
3) Check Input power is available.
4) Check fuse is melted or not, if fuse is melted please contact masibus support department.
17.2 Wrong time at Unit Power ON
If the unit was kept in Power OFF conditions for the duration more than 15 days, as per
mentioned in section 8.2, the battery back of internal RTC will get discharged completely. As a
result, at unit Power ON, time displayed on LCD and time provided in all time outputs will be
according to default internal time till the unit gets LOCKED after GPS antenna is connected to
unit.
If the battery is discharged as per mentioned above, it is necessary to keep unit in Power ON
condition for duration mentioned in section 8.2, for full charging of internal battery. Full charging
is necessary to avoid possibility of wrong time output at unit Power ON.
