(1) If any error occurred to the pressure sensor, the operation can be switched to be hand mode. That means
the operation is controlled by stand-alone system (RUN/STOP)
(2) When under auto mode control, only the master pump cab perform operating control.
(3) When under auto mode control, the slave pumps can be stopped while the motor drive is performing multi-
pump control. If then a run command is given to the slave pump, it will be controlled by the master pump.
