One of the more common questions we are asked, is how to calibrate the coolant level sensor, so the display on the control system is accurate. This week's Tips & Tricks email shows how to set the necessary parameters.
(N.B. Haas does not encourage customers to change parameters, without instruction from a Haas engineer; altering a parameter from its factory set value may have an adverse effect on the machine's performance.)
- The float on your coolant-level sensor needs to be calibrated. To do this, press the PARAM/DGNOS button twice and you will see the Diagnostics display, press Page Down until you find the page where COOLANT LEVEL appears (around the middle of the page).
- Push the float switch in the coolant tank to its lowest position in the tank and record the 5-digit number that appears next to COOLANT LEVEL on the Diagnostics page.
- Let the float return to the highest (full) position, and record the value again.
- Enter the number recorded in step 2 above (empty coolant tank) for parameter 603 and the high number (full coolant tank) for parameter 604.
- Go back to the Current Commands page and confirm that the coolant-level display is working correctly.
