Figure 32. Local mode verification.
1. Set the system for normal flow and ensure that
all system valves are set for normal operation.
2. Place the system in the Local mode.
3. Press the Run key.
4. Click Next to continue.
Figure 33. Set the maximum threshold value.
The Motor/Pump combination capacity is
calculated automatically 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
range of the Maximum threshold zone.

Figure 34. Set the minimum threshold value.
1. The Minimum threshold setting is typically above
the electrical stall of the motor, above the mini-
mum system pressure, above the manual change
plateau, and well below the typical operating
point of the system.
Click 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, stop decreasing and 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
threshold setting.
