0.0–6553.5Vdc
When the absolute value of PV voltage
minus reference voltage is greater than
P15.10, P15.08 and P15.09 are used.
Otherwise, P15.06 and P15.07 are used.
0: Control through digital input
1–2: Reserved
The value 0 indicates the water level
signal is controlled through digital input.
For details, see S terminal functions 43
and 44 of P05. When the terminal input of
full-water signal is valid, the system
reports the full-water pre-alarm (A-tF)
with a delay specified by P15.14 and
then sleeps. In full-water alarm state, the
full-water signal is invalid, the system
clears the full-water alarm with a delay
specified by P15.15 and then re-enters
the running state. When the terminal
input of empty-water signal is valid, the
system reports the empty-water
pre-alarm (A-tL) with a delay specified by
P15.16 and then sleeps. In empty-water
alarm state, the empty-water signal is
invalid, the system clears the
empty-water alarm with a delay specified
by P15.17 and then re-enters the running
state.
