The spindle chiller unit will be powered up automatically whenever you start the spindle motor. It will remain on for several minutes after the spindle stops.
You can set the number of minutes for the chiller to remain on in Machine Parameter 175. The default value is five minutes.
With the spindle stopped, you can also switch the chiller off and on by pressing the Aux3 key.
The Aux3 LED will be lit whenever the chiller is running.
In Manual coolant mode, you can switch CTS coolant on and off using the "Aux11" key. This is the unlabeled Blue key immediately to the right of the Mist coolant key.
In Auto coolant mode, you can switch CTS coolant with the following M functions:
M88 |
CTS coolant on |
M9 |
All coolant off |
M89 |
CTS coolant off (flood and/or mist continue running) |
With the spindle stopped, you can unclamp the tool by pressing the yellow button on the front of the machine head. It takes several seconds for the tool retention fingers to fully open and release the current tool or allow the new tool in.
The work light will switch on automatically on power up. If needed, you can then switch it off and on by pressing the Aux7 key on the pendant.

The PLC program can generate several custom fault messages, in addition to those listed in the Centroid operator's manual. The custom fault messages are listed below, with possible causes and resolutions.
You can use the PLC Diagnostic display on the console to view the PLC input and memory locations mentioned with some of the following fault conditions. At the control's main screen, press Alt-I to activate the PLC Diagnostic display. Press Alt-I again to dismiss it.
The Diagnostic display shows four rows of red and green dots: the first row shows PLC inputs 1 through 80; the second row PLC outputs 1 through 80; the third row PLC memory bits 1 through 80; and the fourth row PLC program stages 1 through 80.
You can use the arrow keys to move a highlight box over any of these locations. The name of the highlighted location will then be displayed at the bottom left.
In addition, the values of the PLC program's first twelve Word (numeric) variables are displayed below the red and green bit indicators. Word variables are used to store tool numbers, turret positions, fault codes, and other scalar data.
Once the cause of a fault is addressed, the fault can be cleared by pressing and releasing Emergency Stop.
One of the flood coolant pumps has tripped its overload relay (OL6 or OL7).
Investigate possible causes and reset the tripped overload. Press Emergency Stop to clear the fault.
Possible causes include a clogged or jammed pump; blocked line; loose connections to the pump; or a damaged cable.

PLC INP12: indicates the combined overload state. Green = 0 = either tripped, Red = 1 = both okay Schematic: Lines 34, 36, 81
The coolant-through-spindle pump has tripped its overload relay (OL8).
Investigate possible causes and reset the tripped overload. Press Emergency Stop to clear the fault.
References:
PLC INP8: indicates the overload state. Green = 0 = tripped, Red = 1 = okay Schematic: Lines 34, 36, 81
The spindle chiller was powered for more than 10 seconds without indicating pressure.
Investigate possible causes. Press Emergency Stop to clear the fault.
See the Kaukan Oil Cooler Regulator Manual for possible causes. Also see the LED status display on the unit itself.

PLC INP9: indicates chiller feedback. Green = 0 = up to pressure, Red = 1 = no pressure or no operation Schematic: Lines 42, 80
One of the axis servo drives has reported a fault. Check the LED displays on the servo drives themselves, in the upper part of the control cabinet, to find out which drive is faulted and what the fault code is. Refer to the Yaskawa Sigma II Series Servo System User's Manual for detailed information on the LED displays and fault codes.
Investigate and resolve possible causes. Press Emergency Stop to clear the fault.

PLC INP20: indicates circuit state: Green = 0 = okay; Red = 1 = at least one drive in fault condition Schematic: Lines 8, 13, 18, 23 and 85
The Centroid PLC interpreter software has encountered an error while processing the PLC logic. Notify your Centroid dealer and service technician.
