Troubelshooting
The pressure readings at the Touch Pad are
inaccurate. The minimum voltage output is below
0.5 VDC and or the maximum voltage output is
above 5 VDC.
Solution : Check wiring and connections to and
from the Transducer. Replace the Transducer.
18) TRANSDUCER MANIFOLD
The Transducer Manifold must be replaced if broken and
allowing leakage.
19) STANDARD HP PUMP ASSEMBLY
The Std High Pressure pump is a marine quality stainless
steel manifold, positive displacement ceramic plunger
pump, operates with minimal noise and vibration.
Problems and Symptoms appearing and caused by the
Std HP Pump:
a)
Pulsations at low and high pressure gauges.
Possible cause
: Worn or broken valve, valve
spring, valve seat. Debris in valve chamber.
Solution
: Check valve chamber for debris, inspect
valve seat. Replace valve assembly as necessary.
b) Water leaks between the pump manifold and rear
crankcase section.
Possible cause : Worn seals or seals damaged due
to running dry.
Solution : Inspect seals and replace if necessary.
c) Normal flow when not pressurized but flow drops
dramatically when pressurized.
Possible cause: Worn seals or seals damage due to
running dry, broken valve, valve spring, or debris in
valve chamber.
Solution : Check seals and valve chambers, clean
chamber or replace parts as necessary.
20) OPTIONAL HP PUMP ASSEMBLY
The Electric Motor is 3 horse power, Totally Enclosed Fan
Cooled, 2 pole, dual Cycle, and dual Voltage.
WARNING ! The High Pressure
Pump MUST rotate in the COUNTER
CLOCKWISE DIRECTION ONLY Rotating
the High Pressure Pump in the clockwise
direction will cause extensive damage to
it. Never operate the High Pressure Pump
in the clockwise direction.
Problems and Symptoms appearing and caused by
the Oil/Water Separator:
a) The Feed Water Pressure into the Oil/Water
Separator is higher than normal, and the Feed
Water Pressure into the High Pressure Pump is
lower than normal.
The pressure differential readings across the Oil/
Water Separator indicate that the element is filled
with debris blocking the feed water.
Solution : Replace the Oil/Water Separator Element.
16) T-CONNECTOR PRESSURE PICK-UP
Outlet of Last Prefiltration component - Inlet of High
Pressure Pump
This T-Connector is for line pressure pick up to
Low Pressure Transducer #2 between the outlet of
the last prefiltration component and the inlet of the
High Pressure pump.
Problems and Symptoms appearing and caused by the
T-Connector Pressure Pick-Up:
a)
The Low Pressure Transducer #2 does not
register pressure.
The 1/4 in. (5 mm) O.D. tube connecting the
T-Connector to the Low Pressure Transducer
Manifold may become kinked or debris may
block the tube.
Solution
: Replace any hose or tube that is kinked.
Disconnect each end of the tube and blow air
through the tube to ensure that it is not blocked.
17) LOW PRESSURE TRANSDUCER #2
Located on the High Pressure Pump Inlet. The Low
Pressure Transducer #2 is for line pressure pick up at the
Inlet of the High Pressure Pump.
The Low Pressure Transducer sends a DC voltage
signal to the System Control Logic. The minimum value
is 0.5 VDC when no pressure is applied to it, and the
maximum value that the System will accept is 4.5 VDC.
The variation of voltage output from the Transducer is
converted to pressure value by the System Control Logic.
Problems and Symptoms appearing and caused by the
Low Pressure Transducer #2:
a)
The Low Pressure Transducer #2 does not register
pressure or the pressure displayed is inaccurate.
Solution : Replace any hose or tube that is kinked.
Disconnect each end of the tube and blow air
through the tube to ensure that it is not blocked.
