Parameters Description
5.3.1 Dry Pump
This group of parameters allows the user to configure dry pump detection, to protect the inverter driven pump.
P1040 – Time Delay for Dry Pump Fault (F765)
Adjustable 0 to 3600 s
Range:
Properties: CFG
Access groups via HMI:
Description:
his parameter defines the waitin time with the dry pump condition active, before the dry pump fault "F765:
Dry Pump" is enerated.
P1041 – Motor Speed for Dry Pump
Adjustable 0.0 to 300.0 Hz
Range:
Properties: CFG
Access groups via HMI:
Description:
This parameter defines the pump motor speed threshold value, above which evaluation of actual motor current
to detect the dry pump condition (P1042) is enabled.
NOTE!
A settin of " " disables the Dry Pump Protection.
P1042 – Motor Current Percentage for Dry Pump
Adjustable 0.0 to 100.0 %
Range:
Properties: CFG
Access groups via HMI:
Description:
This parameter defines the pump motor current percentage threshold value, below which the dry pump
condition is detected.
P1043 – Reset Dry Pump Time
Adjustable 0 to 720 min
Range:
Properties: CFG
Access groups via HMI:
Description:
This parameter defines the time in minutes the reset time of the drive time when the dry pump was detected
to the time the drive is reset.
If this parameter is set to "0", the automatic reset of the Dry Pump condition is disabled.
NOTE!
This parameter may interfere with the automatic auto-reset programmed in parameter P0340, so
if it is necessary to activate the fault reset by Dry Pump, you must deactivate auto-reset by setting
P0340 to "0".
