the amount of time to be added is defined by a setting
tAddToTime
•
time is added through activation of input
ADDTIME
or from LHMI or with
IEC 61850 command

tAlarm
•
warning if output
ACC_HOUR
>
tWarning
The
ACC_HOUR
output represents the accumulated time in hours and the
ACC_DAY
output represents the accumulated time in days.
tAlarm
and
tWarning
are user settable time limit parameters in hours. They are also
independent of each other, that is, there is no check if
tAlarm
>
tWarning
.
tAddToTime
is a user settable time parameter in hours.
tAlarm
,
tWarning
and
tAddToTime
are possible to be defined with a resolution of 0.1
hours (6 minutes).
The limit for the overflow supervision is fixed at 99999.9 hours. The outputs will reset
and the accumulated time will reset and pickup from zero if an overflow occurs.
16.10.6.1
Operation accuracy
GUID-B6FBEFD7-17C8-41C6-B5D5-32E1205E6752 v1
The accuracy of TEILGAPC depends on essentially two factors
•
the pulse length
•
the number of pulses, that is, the number of rising and falling flank pairs
In principle, more pulses may lead to reduced accuracy.
16.10.6.2
Memory storage
GUID-B49698FF-0AB2-4792-A7CB-5534313B6CA0 v2
The value of the accumulated time is retained in a non-volatile memory,
•
at every falling edge of the input
IN
•
at every even 6 minutes, after a rising edge of the input
IN
•
after a manual addition of time
