Check For Leaks, Checking Rotation; Run/Stop Input Options - Xylem CentriPro AQUAVAR SOLO2 Manual De Instalación

• Press and Hold the UP or DOWN button until the desired
pressure setpoint is shown on the Status Display.
• The larger the tank the longer it will take to increase
pressure.
• When desired pressure is reached, close the faucet and
allow the system to shut down.
Pump size determines the maximum flow and head which can
be provided, if flow or head are not sufficient and rotation on
three-phase units has been verified, a larger pump is required.
Checking for leaks
Constant pressure systems utilizing small tanks run
whenever there is demand. Even small leaks can prevent
a pump from turning off. To check for leaks, close all
valves, turn power off to the controller, and note the
pressure displayed on the pressure gauge. Tap the gauge
to ensure you get an accurate reading.
Wait ten minutes and check the gauge again tapping to
prevent the needle from sticking. If the pressure dropped
then the system may have a leak*.
*If a system is pressurized after having been un-
pressurized, it will continue to expand for several
minutes. This expansion causes the pressure to drop
and can be misinterpreted as a leak. Allow a system to
stabilize for 10 minutes under pressure before
performing the aforementioned leak test.
A spring check valve placed on the pump side of the
tank and transducer will often improve the ability of the
system to shut down.
Checking Rotation – 3AS _ _ Models Only
This step only applies to controllers whose
WARNING
model no.'s begin with 3AS. Do not do this
test with 1AS controllers.
Single phase motors having Red, Black & Yellow wires
must always be connected to the RED, BLK and YEL
terminals only. Failure to do so will damage the motor.
For three phase motors, it is possible for the motor to
rotate in the wrong direction. If running backwards,
the pump will work but it will have greatly reduced
performance.
To check rotation, perform the following tests:
Connect an amp probe to one of the power supply
wires. Run the system with several valves open and note
the pressure and amps. Leave the valves open, turn the
power off.
Electrocution Hazard. After turning off
DANGER
power, wait 5 minutes for hazardous
voltages to discharge before proceeding to swap wires.
Swap red and black motor leads where they connect to
the controller terminal block (NOT L1 and L2).
Turn power back on and let the system pressure
stabilize. Again note the pressure and amps. Whichever
wire position provided the most pressure/flow is the
correct wire position. If there was little difference in the
pressure/flow, then whichever had the lower amp reading
is the correct wire position.
Turn the power off, wait 5 minutes and swap the wires
back if necessary.
Replace the plastic protective covers on the terminal
block.

5. RUN/STOP INPUT OPTIONS

5. RUN/STOP INPUT OPTIONS
Run/Stop Input
Electrocution Hazard. Opening RUN/STOP
DANGER
INPUT does not de-energize controller
or any of its outputs. Always treat wire terminals of this
controller as energized until power supply to the controller
has been removed for 5 minutes.
RUN/STOP INPUT - for connection of an external switch
or control device used to start and stop the pump. Devices
such as an over-pressure switch, level (float) switch or any
other non-powered switch (time delay, flow, etc.) can be
connected to this input.
Run/Stop Input wires must never be in the
CAUTION
same conduit with power wires. There
should always be a minimum of 12" between the Run/Stop
Input wiring and the power wires. Failure to separate these
wires can cause controller malfunction.
The Run/Stop Input terminals have a Jumper Wire installed
at the factory (do not confuse the jumper wire on the
Run/Stop Input with the Transducer Jumper next to the
Transducer Connection Terminals, see Transducer Jumper
below). The Run/Stop Input terminals must be connected
(closed) for the pump to operate. If they are not connected
the Run/Stop Indicator (visible inside the enclosure) will
be Solid RED, the Status Display will display STOP and the
Controller Status Light will be Solid GREEN indicating
that the pump-motor is off. Remove the Jumper Wire when
connecting a float or over-pressure switch.
CONSTANT PRESSURE SYSTEM - with an Over-Pressure
Switch:
• Connect two wires from the Load and Lead connections
of a pressure switch to provide over-pressure protection.
In the event the pressure transducer fails, this will prevent
high pressure from damaging piping.
• The over-pressure switch cut-out setting must be a mini-
mum of 10 PSI higher than the system set point pressure.
• Set the over-pressure switch cut-out 5 - 10 PSI lower than
the pressure relief valve (PRV) pop-off pressure. This will
turn the system off before the pressure relief valve opens.
• Ex. On a system with a 50 PSI set point, set the over-pres-
sure switch cut-out at 60 PSI with a typical PRV setting of
75 PSI. In the event the transducer fails at high pressure
the switch will turn the system off before the PRV pops.
• Typical UIB Settings For This Type System:
• For 3AS controllers, 60 or 80 Hertz (depends on pump/
motor)
• For 1AS controllers, Pump Sensitivity Stop – High
(switch to low if control cycles on/off)
• Dry Well - High (switch to low if it trips while pumping
water)
• Low Pressure Cut-Off - On
• Pressure Drop - 5 PSI
• Transducer - Connected
• Transducer Jumper - Bottom Position (Factory Setting)
• Pressure Switch Connected to Run/Stop Input
FLOAT SWITCH OPERATION - Filling a Pond or Tank
(Non-Constant Pressure System):
• Connect two wires from a float (level) switch to fill or
empty a tank, pond, etc. The pump will run when the
level switch contacts close. The maximum switch wire
