Hypertherm XPR460 - Coolant Flow Measurements; Use the CNC or XPR Web Interface to Measure Coolant Flow

What to do next:
■
After you complete a gas leak test in the XPR web interface, select the LOG button to see the result of
the test.
■
The Log screen shows if the test was successful.
■
For a test that was not successful, look for information on the Log screen that identifies the point of
failure.
■
Use the wiring diagrams for your system to find where the gas leak is, using the information from the
Log screen.
Coolant flow measurements
There are two methods to measure coolant flow. You can use the CNC or XPR web interface, or you can
do a container test.
It is necessary for power to be supplied to the cutting system to measure coolant flow. Use extreme
caution if you do diagnosis or maintenance tasks when the system components are
connected to electric power.
WARNING
ELECTRIC SHOCK CAN KILL
The plasma power supply contains dangerous electric voltages that can seriously
injure or kill you. Even if the plasma power supply is turned OFF, you can still get
a serious electric shock if the plasma power supply remains connected to an
electric power source.
Use extreme caution if you do diagnosis or maintenance tasks when the plasma
power supply remains connected to an electric power source and the outer cover
or panels are removed.
Use the CNC or XPR web interface to measure coolant flow
If the coolant flow rate is outside of the correct range, an internal obstruction or leak can be the cause.
1. Look at the CNC or XPR web interface to identify the coolant flow rate.
2. Make sure that the coolant flow rate is more than the minimum flow rate limit for your system.
