Set Maximum Flow Rate (GPM)
The maximum programmed flow rate can be set from 80
GPM to 140 GPM.
Note: Maximum and minimum speed settings, and the
associated alarms, remain active when in Flow mode.
1. Check that the green power LED is on.
2. Press Menu.
3. Press Select to select "Settings".
4. Use the Up or Down arrows to scroll to "Min/Max".
Press Select.
5. Use the Up or Down arrows to scroll to "Set Maximum
Flow".
6. Press Select to change the setting. The cursor will
appear in the first number column (ones).
7. Press the Up or Down arrows to edit the maximum
flow rate setting from 80 to 140 GPM.
8. Press Save to save. To cancel, press Back to exit
edit mode without saving.
9. Press Back to exit.

Set Flow Limit for Speed Program

The flow limit in constant speed program type is disabled
by default. This setting allows the user to ensure that
the drive does not exceed the flow rate output that is set
when they are operating in a constant speed mode. The
system may change during a run at a constant speed
that would increase the flow rate, it this feature is enabled
then the pump will automatically limit itself to keep below
the previously set Maximum Flow Rate.
1. Check that the green power LED is on.
2. Press Menu.
3. Press Select to select "Settings".
4. Use the Up or Down arrows to scroll to "Min/Max"
and press Select.
5. Use the Up or Down arrows to scroll to "Flow Limit
(Speed)".
6. Press Select to move the cursor over the "Disabled".
7. Press and the Up or Down arrows to change it to
"Enabled".
8. Press Save to save. To cancel, press Back to exit
edit mode without saving.
9. Press Back to exit.

Set Maximum System Pressure

The maximum pressure can be set using the drive, so that
the pump does not exceed a set system pressure level
when it is asked to do a high power job, or if the system
changes during normal operation. This gives the user a
better way than Maximum Speed to limit the output of
their pump. If the system is less restrictive, then the pump
is still capable of the higher flow rates than it would have
been if the user had used a speed limit, but the pressure
is still limited where the user needed it to be limited.
The pressure is the total system head, so it is a product
of the suction pressure and the discharge pressure. The
calculated value is equivalent to Total Dynamic Head
(TDH). This value may not correspond with the filter's
pressure reading, because it is the TDH across the pump
and not the local pressure of the filter.
When the pump is running a Flow Program, it will always
attempt to reach the set flow no matter what the system
setup is. If the system pressure changes during the run
(such as from filter dirt loading, or manually changing a
valve position), the drive adjusts motor RPM to maintain
a consistent flow rate.
In some cases the newly requested motor speed will
increase the discharge pressure in order to maintain the
requested flow rate. While maintaining the flow rate, the
drive will remain within the pressure and speed limits set
within the Min/Max menu. If the pump meets one of the
limits, it will continue to run at the limit and the warning
light will illuminate. The limit warning will be displayed on
the bottom of the drives' keypad screen indicating that
the requested flow rate is not being achieved and which
limit that the drive is running into.
When the pump is running a Speed Program, the drive
is not monitoring the flow or pressure limits by default.
These features need to be Enabled in the Min/Max menu.
To Set Maximum System Pressure:
1. Check that the green power LED is on.
2. Press Menu.
3. Press Select to select "Settings".
4. Use the Up or Down arrows to scroll to "Min/Max".
Press Select.
5. Use the Up or Down arrows to scroll to "Set Maximum
Pressure".
6. Press Select to change the setting. The cursor will
appear in the first number column (ones).
7. Press the Up or Down arrows to edit the maximum
flow rate setting from 1 to 50 PSI.
8. Press Save to save. To cancel, press Back to exit
edit mode without saving.
9. Press Back to exit.
