9. Options & Accessories
9.1. Auto Cross
Auto Cross (AC) system automatically switches between the two filter vessels present in unit. Once a
filter bag becomes depleted, the AC system senses the lack of flow and will switch to the clean filter.
PLC will display depleted filter #. The AC system allows for less down time and makes scheduling
filter bag changes far easier. It is recommended that there always be a clean filter present in system,
this allows for un-interrupted operation.
If both filter bags are depleted, the unit will go into alarm.
Be sure to leave both valves to filters open.
Only close valve of filter vessel when changing the filter bag in corresponding filter vessel,
as to not interrupt operation.
Refer to Section 8.1.1. Filter Bag Replacement
9.2. Dual Pressure
2-3 M-Codes are required for a DP system to operate properly. DP option allows for M-Code
controlled pressure reduction. Set higher pressure with main regulator, then utilizing a second
regulator to set a lower pressure. Activating corresponding M-Code allows for reduced pressure.
When lower pressure is no longer needed, ‘release’ corresponding M-Code to return to initial higher
pressure.
DP option useful in machining environments that require small tools that require a lower
pressure, such as small drills or burnishing operations.
9.3. Dual Simultaneous Pressure
Dual Simultaneous Pressure (DSP) option provides two different pressures simultaneously. Port 1
dedicated to higher pressure and Port 2 dedicated to reduced pressure. DSP allows the option of
having high pressure active on tools that require higher pressure while still allowing other parts of
machine tool, such as sub-spindle, to still utilize the reduced coolant flow.
DSP allows both ports/pressures to run independently of one another.
