TEIGAPC main functionalities
•
integration of the elapsed time when IN has been high
•
applicable to long time integration (≤999 999.9 seconds)
•
output
ACCTIME
presents integrated value in seconds
•
integrated value is retained in nonvolatile memory
•
any retained value with a warning/alarm/overflow is used as initiation
value for the integration following by a restart
•
RESET
: Reset of the integration value. Consequently all other outputs are also
reset
•
unconditionally on the input
IN
value
•
reset the value of the nonvolatile memory to zero
•
BLOCK
: Freeze the integration and block/reset the other outputs
•
unconditionally on the signal value
•
BLOCK
request overrides
RESET

•
Monitor and report the conditions of limit transgression
•
overflow if output

The
ACCTIME
output represents the integrated time in seconds while
tOverflow
,
tAlarm
and
tWarning
are the time limit parameters in seconds.
tAlarm
and
tWarning
are user settable limits. They are also independent, that is,
there is no check if
tAlarm
>
tWarning
.
