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.

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)
Note:
When using setting 25, the system units are set by parameter P6-04 and the PID feedback is re-routed to come from the flow meter, pulse
input (H6-01 = 5), or analog (H3-0
o
= 22).
Setting 26: Custom (P1-32 to P1-34)
This setting allows the user to create a custom system unit display with up to three characters. Use parameters P1-32 to P1-34
to make the custom system unit.

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.

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.
This parameter activates the sleep function when the pump reaches the minimum pump speed set in P1-06 for the time set in
P2-03.
No.

P1-04
Start / Draw Down Level
0.0 PSI
<1> Range is 0.0 to 999.9 with sign-bit “-” or “+” indicating Delta to Setpoint.
Range is -999.9 to 999.9 in drive software versions PRG: 8551 and earlier.
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.
