10. Set the system for normal
flow and ensure that all
system valves are set for
normal operation.
11. Place the system in the
Hand
mode and press the
Run
key.
The system will run at the
Upper Limit
setting (
).
12. Click

to continue.
The Motor/Pump combination capacity is automatically calculated and displayed as the
Maximum
threshold. Normally, no further adjustment is required for the
Maximum
threshold setting.
The
Maximum
threshold
value may be adjusted, if required, at
. The
Maximum
threshold setting (
setting comprises the range of the
Maximum
threshold zone.

13. The
Minimum
threshold
value
setting is typically above the
electrical stall of the motor,
above the minimum system
pressure, above the manual
change plateau, and well below
the typical operating point of
the system.
Click in the
Minimum
threshold
field and, using the
Rotary Encoder
,
slowly decrease the
Minimum
threshold
value while observing the LED display.
If either of the conditions listed below should occur while decreasing the
Minimum
threshold
value, increase the
Minimum
threshold number until the condition is no longer
true to set the
Minimum
threshold:
• The motor stalls,
• The output frequency is greater than the setting of
• The output frequency no longer changes with continued

changes.
The
Minimum
threshold setting (
) plus the
setting comprises the range of the
Minimum
threshold setting.
