Clean Water Pool Level Signals:
Water level detection may be operated via a liquid level
transducer or an external liquid level detector. F8-04, F8-05 and F8-06 are respectively used to
set the lower limit signal, upper limit signal and water shortage for the clean water pool. When
the water level drops below the water shortage level, the inverter will automatically switch to
F8-07 (Pressure Settings for Clean Water Pool at the Time of Water Shortage) for operation. This
is intended to prevent max. operation capacity in the case of a water shortage which may cause
unnecessary loss. When the water level signal is lower than the lower water level limit signal, the
system will stop operation and report a water shortage fault. If digital input is selected, any three
digital input terminals are used as liquid level input terminals and respectively set as “water level
detection signals for Clean Water Pools 4, 5 and 6”.
