5.
Send a process command to start the coolant pump.
The coolant pump starts automatically any time a process command is
sent. Refer to
6.
If the coolant flow test value (refer to
) is equal to or greater than 3.78 L/min (1.0 gal/min),
but the XPR web interface shows a lower value, complete the following steps:
a.
Examine the control PCB. Look for +15 VDC on J8 pin 1 and pin 2.
If there is no voltage on J8 pin 1 and pin 2, examine the wiring harness
that connects to J8. Look for a short. If no short is found, replace the
control PCB.
b.
If the voltage on J8 pin 1 and pin 2 is +15 VDC, examine the flow sensor output (in
frequency) at the control PCB. Measure the frequency on J8 pin 3 (pulse) and pin 2
(ground).
If the value differs more than 0.8 L/min (0.2 gal/min), or if there are no
pulses (0 Hz), replace the flow sensor.
7.
If you cannot find or resolve the problem with these corrective actions, contact your cutting
machine supplier or regional Hypertherm Technical Service team.
