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.
Why is there no hydraulic oil pressure in my KMT Cutter?
If there is no hydraulic oil pressure, it may be because: * The high and low limit compensators on the hydraulic pump are blocked with debris and are not controlling the swashplate. Disassemble the compensators, clean and inspect the components. * Incorrect motor rotation, so check the motor rotation.
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.
What causes low cutting water pressure in KMT Cutter?
Low cutting water pressure can be caused by: * Low hydraulic pressure setting, so if operating in low pressure, switch to high pressure operation and check the hydraulic pressure setting. This is not applicable when the machine is equipped with the optional proportional pressure control. * Clean the high pressure adjustment valve. * Clean the compensators on the hydraulic pump. * Collapsed element in the high pressure line filter, so check the element in the high pressure line filter.
What causes abnormal fluctuations in high pressure water signal in KMT Streamline SL-V Plus Cutter?
Abnormal fluctuations in the high-pressure water signal can be caused by: * A large, worn, or damaged orifice, so make sure the orifice does not exceed the capacity of the pump and is in good working condition; verify that the jewel is installed in the orifice mount. * Check valve leakage, so inspect the discharge check valves in the sealing heads. * Seal leakage, so inspect the high pressure seal on the plunger. * Hydraulic control malfunction, so check the operation of the hydraulic relief valve.
Why is the hydraulic pressure present but there is no high pressure water pressure in my KMT Streamline SL-V Plus Cutter?
If you have hydraulic pressure but no high-pressure water pressure, it could be due to: * Proximity switch failure: From the Maintenance Screen on the control panel, jog the intensifier left and right and verify that the red light comes on at both proximity switches. * I/O relay failure: From the Maintenance Screen on the control panel, jog the intensifier left and right and verify that the green light comes on at both directional valve solenoids. * Coil failure on the directional control valve: Check the coils on the directional valve with a volt meter to verify if they are good or bad. * PLC failure: If there are inputs from the proximity switches, but no outputs, contact the KMT Customer Service Department for a logic review and verification of PLC failure.
How to troubleshoot low cutting water supply pressure on a KMT Streamline SL-V Plus Cutter?
To troubleshoot low cutting water supply pressure: * Check for a restricted water supply by verifying cutting water supply flow and pressure. * Inspect for a clogged water filter and replace the filter element if necessary. * Bleed any trapped air from the cutting water plumbing.
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 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.
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.
