Booster Pump Abnormalities; Electrical And Electronic Circuit Abnormalities - Sea Recovery Aqua Mini 170 Owner's Manual

7. If the contactor does not operate mechanically, then measure the DC voltage between A1 and A2 terminals on
the High Pressure Pump Motor contactor coil. It should read 12V DC when activated.
8. If the contactor coil is receiving 12V DC but inoperative then the contactor's coil may be bad. Replace the
contactor.
9. If 12V DC is not present when the High Pressure Pump is activated, trace the orange and orange/black wires
to the main circuit board and measure the DC voltage at the terminals. It should read 12V when activated.

Booster Pump Abnormalities

If the Booster Pump electric motor fails to operate, follow these steps to isolate the problem.
1. Ensure that the system is receiving proper power from the power source.
2. Press "Booster Pump" switch to activate the motor. Do not press any other switch.
3. Measure the AC voltage between Terminals 1 and 2 on the main terminal strip in the controller.
4. If the voltage measured in the step 3 above matches the system voltage, then problems may be in the power
cable attached to the motor or the motor internal wiring or windings.
5. If low or no voltage is present in step 3 above, then check for proper operation of the Booster Pump Contactor.
To deactivate the contactor, press the "Stop" switch twice. To activate the contactor again, press the "Booster
Pump" switch.
6. If the contactor is mechanically operating, but no voltage is present at the motor terminal (step 3 above), then
the Booster Pump Motor contactor may be at fault.
7. If the contactor does not operate mechanically, then measure the DC voltage between A1 and A2 terminals on
the Booster Pump Motor contactor coil. It should read 12V DC when activated.
8. If the contactor coil is receiving 12V DC but inoperative then the contactor's coil may be bad. Replace the
contactor.
9. If 12V DC is not present when the Booster Pump is activated, trace the yellow and yellow/black wires to the
Control Printed Circuit Board and measure the DC voltage at the terminals. It should read 12V when activated.

Electrical and Electronic Circuit Abnormalities

The Start Switch is pressed, but the system does not attempt to start.
1. System is in Fresh Water Flush Mode. Press Stop to exit Fresh Water Flush Mode. Press Start to operate the
system.
2. The LCD on the Touch Pad is not illuminated
• Reset the system circuit breaker.
• There is no main Power to the system from the Power Source, investigate, and correct.
3. Blown Fuse in controller. Check and Replace fuse if blown.
4. Improper wiring. Ensure that system is wired correctly and that there are no loose wire connections.
5. Inadequate power source to the system
• Ensure that the voltage does not drop below the industry standard of 10% of the full operating voltage set for
the system. If the voltage drops below this standard during the system startup, the system will not start. High
current is necessary to "excite" the electric motors. At the time of attempting to start the electric motors, they
will consume high current. This may cause the voltage from the Power Source to drop dramatically for a fraction
of a second which can be enough to cause the electronic circuit to shut off.
• For D.C. systems it is instantaneous, and you will not hear or see this occur. D.C. systems ensure that the
battery bank is fully charged and ensure that the wire size feeding the system is sufficient in diameter to carry
the current without losing voltage. A.C. systems will usually result in the Generator loading down and the
Generator R.P.M. slowing down.
• Provide adequate power to the system.
6. Defective Start Switch on Touch Pad.
• Test with Substitute Touch Pad.
• Replace Touch Pad if one or more lamps or switches are found to be inoperable.
