Func.
Name
Description
F_013
Pump Shift Operation
(Parallel control)
=0: Disable.
=1: Shift the pump operation after the operating time
(F_024).
*The function is to shift the operation from one pump to
another when the operating time (F_024) reaches.
=2: Shift the pump operation after a drive stops.
*The function is to shift the operation from one pump to
another after an operating pump drive comes to stop.
=3: Both 1 and 2 enable.
F_024
Pump Auto Shift Time
(Parallel control)
․
Set the pump operating time of the sequential control
in multi-pump control.
*Setting range:0~240hr.
*0: Disable. (drive will not execute sequential operation.)
F_137
Delay Time at Pump
Shifting
․
The delay time setting is to remain the stable pressure
of the system at the interchanging of the pump
operation.
*Default: 10sec.
*During the pump shifting, the system pressure becomes
unstable when one pump drive disengages and another
pump drive engages. The delay time is to increase the
disengaging time of the current pump drive to stabilize the
system pressure.
