Normal Shutdown Procedure
Never leave waterjet cutting equipment turned on and unattended.
After the equipment is shut down, always make sure the high-pressure water is
relieved by turning on the cutting head.
CAUTION
1. Turn the cutting equipment OFF.
2. Press the (PUMP OFF) on the pump control screen.
3. Pull or rotate the main disconnect handle on the panel door to the OFF position (down).
4. Turn OFF the plant cutting and cooling water connections to the pump.
5. Verify the high-pressure water gauge reads zero (if present) or turn on the cutting head to release
any remaining water pressure.
Emergency Shutdown Procedure
The pump has an EMERGENCY STOP palm button located on the front control panel. In the event of
an emergency, press the EMERGENCY STOP palm button. This will immediately remove any
electrical power from the motor and controls. The bleed-down valve will open and the high-pressure
water should be relieved down the drain.
If the pump is configured to run remotely and has a motion system, the emergency circuits from the
robot or cutting table may be in series with the local emergency stop circuit.
In the event that the pump has been shut down from a remote emergency stop circuit, the operator will
need to remove or reset that condition first. The pump can be re-started following the normal startup
procedure listed earlier in this section. A normally closed dry contact is provided at the back of the
EMERGENCY STOP button for remote equipment shutdown.
