No.
P1-01
Setting 0: Drive only
Designed for single pump stand-alone applications
Setting 1: Contactor lag
Contactor Lag systems multiplex a main pump with up to 5 lag pumps. The drive will stage and de-stage the lag pumps based
on system demand by using its digital output contacts to control the lag pump motor starters
Setting 3: MEMOBUS network
Up to eight drives can be networked together as a coordinated system to provide for system redundancy and precise control.
n P1-02: System Units
Selects the base unit in which most drive PID setpoints, scaling, monitors, limits, and faults/alarm levels will be set.
Note: Set this parameter prior to changing other parameters, as internal scaling is based on P1-02.
No.
P1-02
Setting 0: No unit
Setting 1: PSI: Pounds per square inch
Setting 2: Pa: Pascals
Setting 3: Bar: Bar
Setting 4: "WC: Inch of water
Setting 5: "Hg: Inch of Mercury
Setting 6: ft: feet
Setting 7: m: meters
Setting 8: °F: Degrees Fahrenheit
Setting 9: °C: Degrees Celsius
Setting 10: Percent
Setting 25: Flow (Use P6-04)
n P1-03: Feedback Device Scaling
Sets the feedback device scaling used for the PID controller. This information can be found on the nameplate or specification
sheet and is usually expressed as the maximum output of the device.
For example, a pressure sensor scaling might be 145.0 PSI at 20 mA output and would require setting P1-03 to 145.0 PSI.
Note: Set this parameter prior to changing other parameters related to the PID feedback, as internal scaling is based on P1-03.
No.

n
P1-04: Start / Draw Down Level
Sets the wake up level from the Sleep function. This setting is dependent on whether PID is normal or inverse acting (b5-09).
When the drive is asleep and the PID feedback signal rises above (normal acting) or falls below (inverse acting) this setting
for the time set in P1-05, Start Level Delay Time, the drive will wake up.
No.
P1-04
n P1-05: Start Level Delay Time
Sets the delay time for waking the drive to prevent accidental wake up caused by erratic feedback.
No.
