Clean up the delay time of
overtank pre-warning
Reservoir full of water control
Dormancy delay time of
reservoir full of water
pre-warning
When the detected water level control analog signal less than water level threshold (H00.17), and
continue this status over the delay time of H00.18, reporting the pre-warning of water-full (Arn34), and
dormancy.
In water-full pre-warning, when the detected water level control analog signal larger than H00.17,
delay timer begins, and continue this status over the delay time of H00.16, clear the full-water
pre-warning, recover the normal operation.
Detection of reservoir
hydraulic probe
0.0% means Null.
When not 0.0%, when the detected water level control analog signal larger than H00.19 hydraulic
probe damaged point, hydraulic probe fault (Err32) will be reported directly, and stopped.
Current level of pump
under-load pre-warning.
Delay time of pump
under-load pre-warning.
Delay time of pump
under-load resetting.
0.0%: Automatically detection of under-load, decided by under-load detection of inverter.
When no 0.0%, decided by H00.20 parameter setting, 100% correspondence to ratted current of
motor.
When absolute value of the difference between target frequency and slop frequency continues
less than or equal with H00.23 lag frequency threshold, if the current value continues less than H00.20
set value, over the H00.21 pump under-load delay time, reporting under-load pre-warning(Arn25).
In under-load pre-warning, delay H00.22 under-load reset time, under-load pre-warning restoration.
Use for adjusting the condition of under-load operation. When absolute value of the difference
between target frequency and slop frequency continues less than or equal with lag frequency
threshold, current comparison will be required.
