10.3 Troubleshooting
The following troubleshooting chart lists symptoms, possible causes, and recommended solutions for
troubleshooting the HyPrecision 100D/150D Intensifier Pumps. If you have corrected the fault condition
and still receive a fault message, reset the pump by pressing the
FAULT RESET button on the front
control panel. This will clear the fault and allow you to re-start the pump.
Fault Display Error Message
Hydraulic Oil Level Low
The oil level has dropped from a
leak at a fitting or from performing
maintenance on the hydraulic
assembly.
Inspect the fittings and components of the hydraulic system for
leaks. After identifying the cause of lost oil, add oil per
instructions in the
Hydraulic section of this manual.
Cable may be damaged or connector
is unplugged.
Replace cable if damaged. Plug in connector if unplugged.
Hydraulic Oil Temp > 130F (55C) or Hydraulic Oil Temp > 150F (65C)
Air/Oil Cooled Unit – Fan motor
starter tripped or off. Turn dial to reset and back to run. Determine what caused the
overload to trip if tripped.
Water/Oil Cooled Unit - Inlet
cooling water to the pump not turned
on.
Turn on inlet cooling water. Read the Low-Pressure Water
section of this manual.
Water/Oil Cooled Unit - High
cooling water inlet temperature.
Test the temperature of the inlet water. If the temperature is
outside of the normal range outlined in the
Specifications
section of this manual, you may need a water chiller.
Water/Oil Cooled Unit - Cooling
water flow rate may not be high
enough.
Check the flow rate by monitoring the cooling water out. If the
flow rate is too low then adjust the water-modulating valve or
manual ball valve. See the
Low-Pressure Water section of this
manual.
Cable may be damaged or connector
is unplugged.
Replace cable if damaged. Plug in connector if unplugged.
Heat exchanger could be clogged. Repair or replace heat exchanger.
Inlet Water Pressure Below 40 psi (2.8 bar)
Inlet cutting water to the pump not
turned on. Turn on inlet cutting water. Read the Low-Pressure Water
section of this manual.
The cutting water solenoid may be
shorted.
If the coil or wire is damaged, replace it and restart the pump.
Intensifier Overstroke (pay attention to arrow direction)
The intensifier stroking too quickly
in one or both directions causes this
error. (There may be other possible
causes for this error).
Note the direction of the intensifier over cycle and refer to
Intensifier Cycle in the
High-Pressure Water section of this
manual.
