2 Parameter Description
2.2.9 0-7* Clock Settings
Set the time and date of the internal clock. The internal clock can be used for e.g. Timed Actions, energy log, Trend Analysis, date/time stamps on alarms,
Logged data and Preventive Maintenance.
It is possible to program the clock for Daylight Saving Time / summertime, weekly working days/non-working days including 20 exceptions (holidays
2
etc.). Although the clock settings can be set via the LCP, they can also be set along with timed actions and preventative maintenance functions using the
MCT10 software tool.
NB!
The frequency converter has no back up of the clock function and the set date/time will reset to default (2000-01-01 00:00) after a
power down unless a Real Time Clock module with back up is installed. If no module with back up is installed, it is recommended the
clock function is only used if the frequency converter is integrated into an external system using serial communications, with the system
maintaining synchronization of control equipment clock times. In par. 0-79,
clock has not been set properly, e.g. after a power down.
