DANGER
11. Set the system for normal flow
and ensure that all system valves
are set for normal operation.
12. Place the system in the
Hand
mode and press the
Run
key.

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
F395
. The
Maximum
threshold setting (
F395
) minus the
F482
setting comprises the range of the
Maximum
threshold zone.

Maximum Threshold
15. 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
F505
, or
• The output frequency no longer changes with continued
Virtual Linear Pump
number
changes.
The
Minimum
threshold
setting (
F394
) plus the
F398
setting comprises the range of the
Minimum
threshold
setting.
