Inthisoptionaremanyusefulfunctionstoavoidfutureproblems,likeMotor protector auto reset,Pump exercis-
ing,Pump reversing,anddi󰀨erentscenariosforblockingwhenusingPower monitor.
Motor protector auto reset
Canbedone“Conventional”orbyCA622“Motor drive”.
Conventional needs a digital output which controls an
externalsolenoidtoresetthemotorprotector.
Motor drive requires CA 622 and the reset is sent to the
VFDviasoftware
Pump exercising
Itispossibletoexercisesomepumpsifrequired.
Amaximumpumpo󰀨timecanbesetandexercising
time. The level must be within the parameters.
Pump reversing
Several parameters can trigger reversing.
