Maximum Frequency (Speed) Switch; Dry Well Sensitivity; Low Pressure Cut-Off; Pressure Drop - Xylem CentriPro AQUAVAR SOLO2 Manual De Instalación

• The MODE button is also used to access the Advanced
Menu. To enter the Advanced Menu, press and hold the
MODE button for 5 seconds. See the Advanced Menu
section for details.
Setpoint Select Input
• The controller can store 2 different pressure setpoints.
Only 1 setpoint is active at any time. The active setpoint is
the target pressure for the controller. The active setpoint
is selected through the Setpoint Select Input on the UIB.
• This input can be used to produce 2 different operating
conditions for the system. This can be useful in irrigation
and geothermal systems. Devices such as a timer
controlled relay, float switch, pressure switch or any other
non-powered switch can be used to control this input.
• The Setpoint Select Input wires must
CAUTION
never be in the same conduit with power
wires. There should always be a minimum of 12" between
the Setpoint Select Input wiring and the power wires.
Failure to separate these wires can cause controller
malfunction.
• When the Setpoint Select Input is open the active setpoint
is set to Setpoint 1 ("SP1"). When the Setpoint Select
Input is closed the active setpoint is set to Setpoint 2
("SP2").
BASIC DRIVE SETTINGS AND
PROTECTION

Maximum Frequency (Speed) Switch

3AS _ _ Models Only
This switch is only on models no.'s starting with 3AS. It
selects the maximum frequency (motor speed) used to
energize the motor to be either 60 or 80 Hz.
• 60 Hz - Use for matched pump-motor combinations
where the motor HP and pump HP are the same.
Example: 2 HP WE and 2 HP Motor
• 80 Hz - Use for mis-matched pump-motor combinations
where motor HP is larger than the pump HP (typically 2x
larger). Example: 1 HP WE and 2 HP Motor
Pump Stop Sensitivity – 1AS _ _ Model Only
This switch is only on model numbers starting with 1AS.
Selections are High or Low. High will stop the pump
when speed drops to 40Hz. This provides the fastest
turn off when flow stops. If the pump stops when there
is flow in the system, set the Pump Stop Sensitivity to
Low. Low will stop the pump when speed drops to 30Hz.
Low is less likely to cycle but slower turn-off.

Dry Well Sensitivity

Selections are High or Low. This function protects the
system from running dry. The selection depends on
several conditions and pump size.
Start with the sensitivity on high and test by running
pump at various flows. If a dry well fault is triggered,
switch to low setting.
Restart times vary based on the selections made in the
dSE menu.

Low Pressure Cut-Off

This fault is disabled for the first 10 minutes of pump run
time after power up to allow the system to be purged.
ON Position - Used for constant pressure systems. The
drive will turn off if the system pressure drops 20 PSI
below the system set point pressure for 30 seconds.
This fault must be manually reset, it will not clear
automatically, this may prevent property damage if a pipe
breaks.
OFF Position - Use for open discharge situations such as
filling a pond or tank, or whenever the system pressure
will be 20 PSI or more below the system set point
pressure.
Pressure Drop – 5 PSI or 20 PSI
The pressure drop before the pump restarts can be set to
the standard 5 PSI or to 20 PSI.
The 20 PSI setting results in fewer starts for systems with
leaks. It is recommended for irrigation systems. It will
require a tank pre-charge adjustment. See Tank Sizing and
Tank Pressure Setting.
CURRENT LIMIT PROTECTION

Motor Overload Setting Dial

Failure to properly adjust the Motor
WARNING
Overload Setting before applying power may
damage the motor or wire and void the warranty.
• Use Tables 3 and 4 to determine which controller and
setting to use. Note that some 200V motors require
upsizing to the next larger controller.
• Set the Motor Overload - Turn the dial pointer to align
with the motor's service factor amps (SFA). For three
phase motors and any other motor without integral
thermal protection choose the amperage value on the
UIB that is less than or equal to the SFA listed on the
nameplate. For single phase motors and other motors
with integral thermal protection choose the amperage
value on the UIB that is closest to the SFA listed on the
nameplate.
• If the output current exceeds the motor overload setting,
the controller will limit current by reducing the output
voltage and frequency. This will reduce the performance
of the pump. The controller tracks the thermal load of the
motor by monitoring the output current and comparing
this value to the motor overload setting. If the motor
overload setting is set too low, nuisance tripping on Over
Current (04, 4 red blinks) can result.

4: START UP PROCEDURE

4. START UP PROCEDURE
Purge the System of Air
• Insure that plumbing connections are tight and wire
connections are correct.
• Partially open a valve and turn power to controller on.
• Run the pump and controller with the furthest and
highest faucets or valves in the system open. This will
allow all air to escape the piping system.
• When flow is constant, close the faucets or valves and
allow the system pressure to reach the pressure setpoint
and shutdown.
PRESSURE ADJUSTMENT – Only if pressure
other than 60 PSI is desired:
• Adjust tank pressure according to the desired set pressure
- see Tank Sizing and Tank Pressure Setting section.
• Open a faucet and allow pump to start and purge the
system of air.
