Parameter Descriptions
0-67 Bus Access Password
Range: Function:
0 [0 - 9999 ] Use this parameter to unlock the
*
frequency converter via fieldbus or
MCT 10 Set-up Software.
3.2.11 0-7* Clock Settings
Set the time and date of the internal clock. The internal
clock can be used for timed actions, energy log, trend
analysis, date/time stamps on alarms, logged data,
preventive maintenance, and so on.
It is possible to program the clock for daylight saving time/
summertime, weekly working days/non-working days
including 20 exceptions (holidays, and so on). 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 MCT 10 Set-up Software tool.
NOTICE
The frequency converter has no back-up of the clock
function and the set date/time resets 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, only use the clock function if the
frequency converter is integrated into the BMS using
serial communications, with the BMS maintaining
synchronization of control equipment clock times. In
parameter 0-79 Clock Fault, it is possible to program for a
warning if the clock has not been set properly, for
example after a power down.
NOTICE
®
If mounting VLT Analog I/O Option MCB 109, a battery
back-up of the date and time is included.
