test 1 – return line
Note: An in-line flow meter is required to complete this test.
1. Turn OFF the power. Remove the return coolant line
(red washer on the cooler fitting), and connect the flow
meter to measure the flow rate.
2. Measure the flow rate on the flow meter. Turn ON the
power. Turn ON the pump manually using the manual
pump control button on your CNC screen (see step 1
under “Manual pump operation”). Write down the flow
rate from the flow meter.
3. Reconnect the return coolant line (red washer on the
cooler fitting).
If the flow rate is 0.8 gpm or more, replace the flow switch.
If the flow rate is less than 0.8 gpm, Go to test 2.
If there is no flow, go to pump and motor troubleshooting.
test 2 – supply line at ignition console
Note: Remove the torch-lead coolant hoses to access the supply line.
1. Turn OFF the power. Remove the supply coolant line (blue hose with
green tape) from the RHF/LHF console, and place it in a 3.8 liter
(1 gallon) container. A Hypertherm coolant container works well.
2. Measure how long it takes to fill the container. Turn ON the power.
Turn ON the pump manually using the manual pump control button
on your CNC screen (see step 1 under “Manual pump operation”).
Write down how long it takes to fill the container.
3. Reconnect the coolant lines.
If the container is full in 65 seconds or less, go to test 3.
If it takes more than 65 seconds to fill the container, go to test 6.
