coolant flow tests
If the CNC screen shows a coolant flow error (093 or 060), turn OFF the system and then ON again to clear the error.
Then perform the following tests to find the cause of the problem.
An in-line flow meter is the most accurate way to measure the flow rate, but can not be used with all the tests described
without custom fittings. An in-line flow meter (part number 128933) is available from Hypertherm. The following “bucket”
tests give a good idea of the flow rate.
Note: The CNC screens shown here are for reference. The screens you work with may look different, but should
have the same functions shown here.
before testing
Notes: It is important to follow the troubleshooting steps in the order in which they are shown in the flow chart on
the previous page.
Coolant must be drained from the system before the in-line filter is cleaned (step 1 below). The coolant in
the system will drain out as soon as the in-line filter is removed.
1. Clean the in-line filter.
2. Replace the filter element on the rear of the cooler.
3. Verify that the system has the correct level of coolant when refilling the system after completing steps 1 and 2. See
fill the cooler with coolant in the
Installation
section.
