Operation

Note:
Always run the charge pump for a few minutes following an initial power up. This flushes out the warmer
water, ensuring that the seals are cooled prior to high-pressure pump operation.
Caution:
It is essential that the cylinders surrounding the dynamic seals stay beneath 70 degrees F
during high-pressure operation. Operating the pump at high pressures when seal temperatures
are 80 degrees F or more dramatically reduces their useful life. Cylinder temperature will begin
to rise immediately following a shutdown with the charge pump off. 80 degrees F could easily
be reached during a prolonged shutdown. As a precaution following an extended shutdown
such as during a lunch break, always run the charge pump for as long as it takes to lower water
temperature in the white water tank to that of the inlet water temperature prior to resuming
cutting.
5.
Verify that the PC Controller starts and stops the pump as required for operation.
6.
Once the pump starts, verify that the red LED next to the
Run
button on the keypad is lit (see
Figure 2-4), and the RPM reading on the display achieves the “Hi PreSet” value.
Stopping the Pump
1.
Press the keypad’s
Stop
button.
2.
If the pump is connected to an OMAX JetMachining Center, the PC Controller automatically starts
and stops the pump as required during operation.
Note:
The pump may be stopped at any time by pressing the emergency stop switch, either on the pump or on
the JetMachining Center controller.
3.
When the pump stops, verify that the red LED next to the keypad’s
Stop
button is lit (see Figure 2-
4).
4.
Turn the charge pump switch to its
OFF
position.
5.
Turn the pump On/Off switch to its
OFF
position.
Emergency Shutdown Procedures
Pushing the emergency stop switch in, immediately shuts down both the pump and the JetMachining
Center. The emergency stop switch is reset by manually pulling it back to its original position. The pump
cannot be restarted until the emergency stop switch is reset.
Note:
If the pump is connected to an OMAX JetMachining Center, pushing the emergency stop switch in at any
time (either the emergency stop switch on the pump itself, or the emergency stop switch on the
JetMachining Center) immediately shuts down both the pump and the JetMachining Center.
Setting the Pump RPM
The pump RPM, which determines cutting pressure, may be adjusted up or down using the keypad’s
arrow
buttons while the pump is either running or not running. Generally, both the high and low operating
pressures are preset with the pump operating in a test mode.
1.
To increase the high-pressure value, press the keypad’s
up
arrow.
The “Hi PreSet” RPM value will increase. If the pump is running when this arrow button is pressed,
the pressure shown on the keypad display also increases. When the pump is running and the “Hi
PreSet” RPM results in an output pressure greater than the maximum allowed, the RPM value
decreases to conform to the maximum allowable pressure. The display screen will then repeatedly
flash the message “@MAX”.
2.
To decrease the high-pressure value, press the keypad’s
down
arrow.
The “Hi PreSet” RPM value decreases. If the pump is running when this arrow button is pressed,
the pressure shown on the keypad display also decreases.
