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
