ChipBLASTER, Inc. 26
12.0. OPERATION: (Cont.):
12.3. THEORY OF OPERATION AUTO CROSS OPTION:
12.3.1. The ChipBLASTER is designed to operate with two (2) filters. The
ChipBLASTER will typically start on filter A and run until this filter
becomes clogged (dirty). When the filter becomes clogged (dirty) the flow
will be switched to filter B automatically. The red tower light will begin to
flash indicating a clogged (dirty) filter A. The ChipBLASTER will
continue to operate.
12.3.2. While the ChipBLASTER is running on filter B, filter A can be changed.
(refer to Section 14.9 for procedure)
12.3.3. When the ChipBLASTER is running on filter B and it becomes clogged
(dirty) the ChipBLASTER will go to an emergency stop condition after the “call
for coolant” is shut off. This will prevent damage to the high pressure pump.
12.3.4. It should be noted the filter bag A or B is monitored when the ChipBLASTER is
operating. The post filter is also monitored when the ChipBLASTER is operating.
If the post filter becomes dirty the red tower light will turn on steady.
The reason the post filter can become dirty is do to improper changing of the filter
bags. Improper changing will allow chips or contaminates into the bottom of the
filter housing which than pass to the post filter. The post filter is designed to
prevent chips or contaminates from going through the high pressure pump and
damaging the seals. The post filter also prevents chips or contaminates from
damaging solenoid vales and pressure switches.
12.3.5. Refer to figure 6b section 12.2 for flow diagram
12.3.6. The autocross units are also equipped to change from filter “A” to “B” after a
timed period. This prevents coolant in filter “B” from becoming stagnate and
allowing algae to grow. The ChipBLASTER will start out on filter “A” and after
one (1) hour of accumulated run time the flow will be diverted through filter “B”.
Filter “B” will be used for twenty (20) minutes and than change back to filter “A”.
This cycle will repeat until a filter becomes dirty at which time the timed change
over will be stopped until the filters are changed. During the timed change over
the filters will still be monitored.
