code
During the alarm, the empty -water signal
is invalid and the system will clear the
alarm after the time of P15.17.
If the function code is 1~3, it is the
reference of water-level control analog
signal. For details, see P15.12 and
P12.13.
0.0~100.0%
This code is valid when P15.11 water
level control is based on analog input. If
the detected water level control analog
signal is less than the water level
threshold P15.12 and keeps in the state
after the delay time P15.14, the system
reports A-tF and sleeps.
If the delay time is not reached, the
signal is bigger than the water level
Full-water level
○
P15.12 threshold, the time will be cleared 25.0%
threshold
automatically. When the measured water
level control analog signal is less than
the water level threshold, the delay time
will be counted again.
0 is full water and 1 is no water.
During the full-water alarm, if the
detected water level signal is higher than
the threshold of P15.12 and the delay
counts, the alarm is cleared after the
time set by P15.15 is reached in this
