Write
Total time where valve position is equal to or
less than OPEN_CLOSE_THRESHOLD. To
reset the count, write 0.
— Threshold value for TOTAL_OPEN_TIME and
TOTAL_CLOSE_TIME.
High-limit alarm setting for
TOTAL_OPEN_TIME.
When TOTAL_OPEN_TIME has reached this
setting, a block alarm is generated.
High-limit alarm setting for
TOTAL_CLOSE_TIME.
When TOTAL_CLOSE_TIME has reached this
setting, a block alarm is generated.
O/S Total time period when the valve position is
equal to or less than the value set in
NEAR_CLOSE_THRESHOLD (judged as
when the valve is nearly closed). To reset the
count, write 0.
Threshold for judging that the valve is nearly
closed
High-limit alarm setting for
TOTAL_NEAR_CLOSE_TIM. When
TOTAL_NEAR_CLOSE_TIM has reached this
setting, a block alarm is generated.
Deviation high limit (%)
If the time period when the deviation is
continuously equal to or greater than
DEVIATION_LIM has reached the time set for
the first value in this parameter, a block alarm
is generated. If it has reached the time set for
the second value, the instrument transfers to
fault state. Negative value means off.
