Description
This fault indicates a problem with the pressure sensor feedback.
Verify the connections from the AquaBoost II Controller to the
pressure sensor. Turn power to controller off and wait 5 minutes.
Remove controller access panel. Be sure sensor cable is wired as
shown in Diagram 4. If cable is wired correctly, check the voltage on
the Input (White) pressure sensor terminal connection in the
AquaBoost II controller. Using a DC voltmeter, connect the positive
lead to the Input (White) pressure sensor terminal connection, connect
the negative lead to the Com. (Black) pressure sensor terminal
connection. Turn power to controller on. The DC voltage measured
should be in the valid range of 0.5 Vdc to 4.5 Vdc (+/- 0.2 Vdc). If the
voltage is outside this range, replace pressure sensor.
This fault can be caused by mechanical binding from debris in pump
or from an electrical failure in the motor. Verify the error by turning
power to controller off for 1 minute and then on. Pump must be
checked if error persists.
Check wiring for shorting phase to phase and phase to ground. Turn
power to controller off and wait 5 minutes. Remove controller
access panel. Disconnect motor leads marked T1, T2, and T3. Measure
resistance between all motor leads using an ohmmeter. Note: Motor
winding resistance is typically 2 to 10 OHMS depending on motor.
Check wiring for shorting phase to ground. Turn power to controller
off and wait 5 minutes. Remove controller access panel. Disconnect
motor leads T1, T2, T3, and Ground from controller. Measure
resistance between all motor leads and ground using a
Megohmmeter. Connect one Megohmmeter lead to any one of the
motor leads and the other to ground lead. Set Megohmmeter to 500V
DC output. Resistance readings less than 500,000 ohms or 0.5
Megohms indicate a damaged motor.
This fault is caused by a high temperature inside of the controller. The
controller will shut off when the temperature inside the controller
reaches 158º F (70º C). The controller will turn back on when the
temperature inside the controller reaches 150º F (65.5º C). Avoid
installing the controller where ambient temperatures exceed 104º F
(40º C). Avoid installing the controller where it is exposed to direct
sunlight.
and negative leads to L1 and L2 on the AquaBoost II controller. Verify
line input voltage is not greater than 264 VAC.
This fault is indicated when the current supplied to the motor exceeds
the Motor Overload Setting on the AquaBoost II controller. Refer to
Section 7, Setting the Motor Overload DIP Switches for details. If
switches are set according to Section 7, check motor.
