Function & F
eatures
The table below lists all of the Parameters used in this function:
Parameter Name Value/Range Notes
75.24 MULTIVAR CTL OFF [default]
ON
Set to “ON” to enable the Multivariable functionality
75.25 MULTIVAR REF SOURCE
Analog Input 1
Analog Input 2
This parameter defines the source used in the
Multivariable control function. Choices are from any
available Analog Input. The selected Input will need to
be fully configured as “Proc Trans 2”
75.26 LEVEL 1 Range: 0-9999
0 [default]
This is the first level in which the Multivariable control
function will scale the set-point as it is defined by the
LO INTRCPT value and SP LO value. LEVEL 1 is defined
in units of the secondary process variable.
75.27 SP LO Range: ±20000
0 [default]
This is the lower limit set-point as related to LO IN-
TRCPT. SP LO is defined in units of the primary process
variable or RPM when in speed control.
75.28 LO INTRCPT Range: 0-9999
0 [default]
This is the lower limit level in which the Multivariable
function will scale the set-point as defined by the SP LO
value. LO INTRCPT is defined in units of the secondary
process variable.
75.29 LEVEL 2 Range: 0-9999
100 [default]
This is the upper level in which the Multivariable
control function will scale the set-point as it is defined
by the HI INTRCPT value and SP HI value. LEVEL 2 is
defined in units of the secondary process variable.
75.30 SP HI Range: ±20000
0 [default]
This is the upper limit set-point as related to HI IN-
TRCPT. SP HI is defined in units of the primary process
variable or RPM when in speed control.
75.31 HI INTRCPT Range: 0-9999
0 [default]
This is the upper limit level in which the Multivariable
function will scale the set-point as defined by the SP HI
value. HI INTRCPT is defined in units of the secondary
process variable.
Parameter Backup/Restoring
The PS220 has the ability to save all of the parameter settings configured to run the pump within
the Keypads on board memory. This is called a Backup. This backup will also allow the ability to
restore all parameter settings if the need arises. Two pump configuration backup files can be cre-
ated using this function. This may allow you to reconfigure the drive to operate separate configu-
rations for the same pump in service.
The Backup Functionality also can create an “Automatic backup”. This is created two hours after
any parameter changes, or if a backup was not created manually. After 24 hours the ”Automatic
Backup Function” completes a compare function, which compares the existing backup to how the
PS220 is currently configured, and again will automatically create a new backup overwriting the
previous one. When viewing the backup files, there will be “Folded Page Icon” with the letter “A”
shown on the top left corner signifying that this was Automatically created. See the Screen shot
