User Manual

Power fault
• To maintain reliable normal operation (e.g. trend logging, alarm handling, reporting)
the CMT restarts automatically after a power failure.
• By selecting the optional uninterruptable power supply (HPB10-UPS), it is possible
to maintain normal monitoring and operation during a short mains power outage.
Backup and archiving
• An external removable hard disk is installed for backup data storage and for
restoring data, to accommodate all configured data point databases, all application
databases, all graphics databases, all user-defined reports and all historical data.
• The data is regularly backed up according to our backup strategy, for more details
we refer to the CMT manual.
• The backup of the trend and log data in the databases is carried out automatically
hourly, daily and weekly.
• For the offline archiving, the data must be archived manually for safety reasons
