The bigger the value is, the stronger the
effect and faster the adjustment is.
0.0~6553.5Vdc
If the absolute value of bus voltage
minus the reference value is bigger than
P15.10, it will switch to P15.08 and
P15.09; otherwise it is P15.06 and
P15.07.
0: Digital input of the water-level control
1: AI1(the water-level signal is input
through AI1, not supported currently)
2: AI2 (the water-level signal is input
through AI2)
3: AI3 (the water-level signal is input
through AI3)
If the function code is 0, the water-level
signal is controlled by the digital input.
See 43 and 44 functions of S terminals in
group P05 for detailed information. If the
full-water signal is valid, the system will
report the alarm (A-tF) and sleep after
the time of P15.14. During the alarm, the
full-water signal is invalid and the system
will clear the alarm after the time of
P15.15. If the empty-water signal is valid,
the system will report the alarm (A-tL)
and sleep after the time of P15.16.
