The condition：hi-hi limit value≥higher limit value≥lower limit value≥lo-lo limit value
Note： 1. When one of the higher/lower limit value is set “0”, it will not be compared. For
example, if HH is set “00”, “HH” will not be compared, i.e. the output terminal of “HH” is invalid.
2．Lag：the range of the delay after alarm, the unit is “d”.
Example：HH limit value is 1000，and the lag is 20.
When the value participating in the comparison ≥1000, the alarm starts. The comparison
is selected by the comparison
condition of F7.
When the value participating in the comparison≤1000-20, the alarm exits. The comparison
is selected by the comparison
condition of F7.
In the upper/lower setting, the former two bits before“-”display the limit value，the
latter three bits display the lag.
Note：The range of lag is 000-100。The lag>100，”Err” is displayed for about 2 seconds
and get back to “SET-HH” automatically。
