27.0. OPTIONAL EQUIPMENT (Cont.):
27.19. PRESET PRESSURES:
27.19.1. Preset pressures add the flexibility of four pre programmed drive speeds to give
four separate operating pressures by the use of “M” codes from the machine
tool. The machine tool control must be capable of a total of 4 sets of
maintained (on and off) “M” codes total for a single outlet ChipBLASTER or
5 sets of maintained (on and off) for a two outlet ChipBLASTER. The
machine tool must also be capable of supplying two maintained “M” codes at
the same time for pressures of 750, 500 and 250 to 300 psig. The call for
coolant “M” code used to energize CR1 and/or CR2 (if used) alone will be
used for pressure number 1 typically 1000 PSIG (68.9 Bar). The call for
coolant “M” code used to energize CR1 and/or CR2 (if used) and CR21 will be
used for pressure number 2 typically 750 PSIG (51.7 Bar). The call for coolant
“M” code used to energize CR1 and/or CR2 (if used) and CR22 will be used
for pressure number 3 typically 500 PSIG (34.4 Bar). The call for coolant “M”
code used to energize CR1 and/or CR2 (if used) and CR23 will be used for
pressure number 4 typically between 250 and 300 PSIG (17.2 and 20.6 Bar).
Refer to figure 21 for chart.
NOTE: OTHER PRESSURE SETTINGS ARE AVAILABLE BETWEEN THE MINIMUM
AND MAXIMUM RANGE OF THE ChipBLASTER UNIT. FOR OTHER SETTING PLEASE
ADVISE ChipBLASTER Inc. AT THE TIME OF ORDER.
IT IS RECOMMENDED THAT PRESET PRESSURES BE PURCHASED

IF MAINTAINED “M” CODES ARE NOT AVAILABLE PLEASE CONTACT
ChipBLASTER SALES FOR AN INTERFACE TO CONVERT PULSED OR MONENTARY
“M” CODES TO MAINTAINED. PLEASE PROVIDE THE FOLLOWING INFORMATION:
27.19.2. Voltage of signal i.e. 24 VDC or 110 VAC.
27.19.3. Is acknowledgement “ACK” or finish “FIN” signal is required by machine tool.
27.19.4. Will one “M” code turn on each of the call for coolant and / or pressure requests
and than use one “M” code to shut all “M” codes off.
27.19.5. Also any special considerations that may be required.
DO NOT EXCEED THE MACHINE TOOL MANUFACTURERS
MAXIMUM OPERATING PRESSURE.
