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
threshold, the time will be cleared
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
continuous state continues. During the
non-continuous application, the delay
