DynaMAX 550P/560P/575P Waterjet Pump Operator Manual 811390 159
Overstroke
Is the bleed-down valve hot?
Monitor the intensifier stroke rate indicator on the operator interface.
If 1 side of the intensifier is stroking too fast, is there a leak from a weep hole on the intensifier?
Yes The bleed-down valve has failed. Repair or replace the bleed-down valve.
The bleed-down valve is not getting air. • Make sure that the compressed air source is
on.
• Make sure that the compressed air hose is
not damaged.
• Make sure that the compressed air hose is
connected correctly.
No The difference between the values on the prefilter
water-pressure gauge and the postfilter
water-pressure gauge is lower
than0.7bar(10psi).
Replace the water filters.
The prefilter water-pressure gauge shows that
the low-pressure water is lower
than2.8bar(40psi).
• Make sure that the water to the pump is on.
• Make sure that the low-pressure water line is
connected to the intensifier.
• If the pump has a boost pump, examine the
10-micron water filter. If the filter is black, the
boost pump has failed and must be replaced.
Contact a Hypertherm Technical Service
Associate for information and support.
• While the pump is operating, make sure that
the LED on the low-pressure water drain
valve solenoid is on. The light shows that the
solenoid is closed.
Low water pressure can cause an
overstroke without triggering the
low-pressure alarm for the
low-pressure water.
Yes High-pressure seal Inspect the high-pressure seal.
Check valve weep hole Check the output adapter torque.
Check the high-pressure fitting torque.
High-pressure endcap and high-pressure
cylinder
Check the torque.
The check valve or the high-pressure cylinder is
cracked
Inspect the check valve O-ring.
