4.
Examine the XPR web interface. Make sure that the speed for each magnetics fan is within the
acceptable range (magnetics fan 1; magnetics fan 2).
During normal operation, it is usually difficult to see individual blades
because of the fast speed of the fan rotation). If you can easily see
individual blades without the use of a strobe lamp, the rotation speed is
probably too slow.
5.
If the speed of the fans is below the acceptable range (refer to table above), remove the
electrical power from the cutting system. Refer to
Remove the power from the cutting system
6.
Remove the front panel of the plasma power supply.
7.
If you find obstructions, debris, or dust, use compressed air to remove the obstruction, debris, or
dust from the fans and magnetics area.
The magnetics area can retain large amounts of dust or debris. Multiple
uses of compressed air is often necessary to clear this area. Consider the
use of personal protective equipment to protect yourself from airborne
particulates and debris.
Make sure to minimize fan rotation during compressed air use. You can
use a gloved hand to hold a fan in position, if necessary.
8.
If both magnetics fans have no obvious obstruction, dust, or debris:
a.
Disconnect the connector from the control board PCB 1 (for the magnetics).
b.
Use a digital multimeter to measure the resistance from each thermistor wire, based on the
following connector-pin locations:
Thermistors are located on the magnetics.
