When 23-19 = 0 or 23-78 = 0, function of l oss pressure detection is disabled.
When 23-19 > 0, If the feedback pressure value is lower than the value of
【
(23-02) x (23-19)
】
and the
detection time of loss pressure (23-18) passes, the inverter jumps to fault signal (FBLSS).
When 23-78=1, the inverter will display warning signal when detecting the loss pressure.
When 23-78=2, the inverter will display error signal when detecting the loss pressure.

*1: 23-20=0, presents the unit and range.
*2: 23-20=1, presents the unit and range.
Acceleration time of water pressure detection (23-26) and deceleration time of water pressure detection
(23-27) are corresponding to the acceleration time 2 (00-16) and the deceleration time 2 (00-17), so the
setting of 23-26 changed with the setting of 00-16. Thus, avoid using multi-speed application function while
using PUMP function.
