Description of Real Time Clock

NB!:
Please note the following parameters are only
displayed if the real time clock option is fitted!
The real time clock can show the current time
and date and weekday. The available digits stipulate
how comprehensive the readout can be.
Further more the RTC is used to execute events based
on time. A total of 20 events can be programmed.
Firstly the current time and date must be programmed
in parameter 780 and 781, please see description of
parameters. It is important that both parameters are
set. Then parameter 782 through 786 and 789 are
used to program the events. First set the week-day(s)
in parameter 782 when the action shall take place.
Then set the specific time in parameter 783 for the
action, then the action itself in parameter 784. In
parameter 785 set the time for the termination of the
action and in parameter 786 the off-action. Please
note the on action and off action must be related. E.g.
it is not possible to change setup via the on-action
in parameter 784 and then stop drive in parameter
786. The following selection refers to the choices in
parameter 784 and 786. Hence selection [1] to [4] are
related, [5] to [8] are related, [9] to [12] are related, [13]
to [16] are related and finally [17] and [18] are related.

It can be chosen if an action, on start-up, shall be
executed even if the ON time has been passed some
time ago. Alternatively choose to wait for the next
forth coming ON action time before executing the
next coming action. This is programmed in parameter
789. It is, however, possible to have several RTC
actions within the same period. E.g. relay 1 ON is
= factory setting. () = display text [] = value for use in communication via serial communication port

executed in the first event at 10:00 and relay 2 ON
is executed in the second event at 10:02, before the
first event is terminated. Parameter 655 will show
the fault log with the RTC, this parameter is directly
related to parameter 616. Only here the log is based
on the real time clock, not running hours from zero.
This means a date and time is shown.
