TEILGAPC main functionalities
• IN: Accumulation of the elapsed time when input IN is high
• applicable to very long time accumulation (≤
99999.9
hours)
• output
ACC_HOUR
presents accumulated value in hours and
ACC_DAY
presents
accumulated value in days
• accumulated value is retained in a non-volatile memory
• any retained value is used as initiation value for the integration following by a restart
• RESET: Reset of the accumulated value. Consequently all other outputs are also reset
• independent of the input
IN
value
• reset the value of the nonvolatile memory to zero.
Note that the nonvolatile memory will not reset to zero if the input
IN
is high during the
reset.
• reset can be made by activation of input
RESET
or from LHMI or with IEC 61850
command
• ADDTIME: Manually add time to the currently accumulated time
• 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
• BLOCK: Freeze the accumulation and block/reset the other outputs
• independent of the input
