Why is the outlet booster pump pressure falling below 60 psi in my KMT Cutter?
If the outlet booster pump pressure is falling below 60 psi, it could be due to: * Low inlet water pressure. * A dirty filter element that needs to be replaced. * The booster pump needing adjustment or replacement; the booster pump should be adjusted to 120 psi (8 bar) when deadheaded.
What to do if the KMT Streamline SL-V Plus Cutter pump quits running?
If the pump quits running, it could be due to: * Unsafe operation being detected, so check the display panel for fault messages. * Electrical power interruption, so check the power supply circuit for a tripped breaker. * Check the input and output of the 24 volt DC power supply. * Verify that power is available at the main power source. * Check the 2K1 relay coil. * Check the 4K0 relay. * The motor overload relay has been tripped; identify the source of the overload, remedy the problem, and reset the overload relay.
Why is there no control power to my KMT Cutter?
If there is no control power, the possible causes are: * A tripped circuit breaker, so check the input and output of all circuit breakers. * A power supply fault, so check the input and output voltages at the power supply. * The emergency stop button is depressed, so pull the e-stop button out. * The master control relay is not energized, so verify that the contactor coil is pulling in on the master control relay. * Contact set failure on the master control relay, so verify that the contact sets on the master control relay are changing states when the relay is energized.
What to do if the console display and lights do not illuminate on KMT Streamline SL-V Plus?
If the console display and lights do not illuminate, check for the following: * Ensure the emergency stop button is not depressed; pull it out if it is. * Verify main power is connected and the main power disconnect is on. * Check the power supply circuit for a tripped breaker. * Check the input and output of the 24 volt DC power supply. * Check the 2K1 relay.
What causes high oil temperature resulting in shutdown in KMT Streamline SL-V Plus?
High oil temperature leading to a shutdown can be caused by: * Restricted cooling water flow, so check the cooling water source for proper temperature and flow rate. * A water modulating valve stuck open or closed, in which case you should replace the valve. * Scale build-up in the heat exchanger restricting the flow, so the heat exchanger will need to be flushed or replaced. * Air cooler temperature switch not operating properly, so replace the switch. * No power to cooler fan motor, so check the power supply to the fan motor.
What causes water leaking from the weep hole on the hydraulic cylinder head flange of KMT Cutter?
If water is leaking from the weep hole on the hydraulic cylinder head flange, it could be due to: * A failed high pressure seal assembly, so replace the high pressure seal assembly. * A damaged plunger, so check the plunger for longitudinal scratches or flaws. If detected, replace the plunger or return to KMT Waterjet for evaluation and rework. * Seal material buildup on plunger, so polish the plunger surface. * A damaged high pressure cylinder, so check for scratches, grooves or material buildup on the inside diameter of the cylinder.
What causes water leaking from the weep hole in the sealing head gland nut of KMT Streamline SL-V Plus Cutter?
Water leaking from the weep hole in the sealing head gland nut can be caused by: * High pressure piping gland nut is not tight and is not sealing properly, so tighten the gland nut to the proper torque specification. * Improper high pressure piping connection, so check the number of exposed threads past the collar on the high pressure piping. Only 1- 1/2 to 2-1/2 threads should be exposed. * Damaged sealing head gland nut, so check the gland nut for cracks due to fatigue. If cracks are detected, replace the gland nut.
What causes hydraulic oil leaking from the weep hole in the hydraulic cylinder head of KMT Streamline SL-V Plus Cutter?
If hydraulic oil is leaking from the weep hole in the hydraulic cylinder head, it's likely due to a failed hydraulic cartridge seal. Replace the cartridge seal. If the leak persists, check the plunger for linear scratches or scoring.
What causes erratic pressure fluctuations in the KMT Streamline SL-V Plus?
Erratic fluctuations in operating pressure, or the inability to reach or maintain set pressure, can occur if the screen in the proportional pressure valve is blocked with debris. Remove the valve and clean the screen.
What to do if the KMT Cutter pump shaft will not turn?
If the pump shaft will not turn, it could be due to: * The flexible coupling has failed, so replace the flexible coupling. * The hydraulic pump has seized, so replace the hydraulic pump.
