output pressures.
HyPrecision Predictive waterjet pump Operator Manual 810120
Stage 1: Supply water pressure
Touch the symbol on the Start Procedure screen.
 The beacon light flashes green at 1-second intervals during the start
procedure.
 The primary motor starts.
 If the system has a boost pump, it turns on.

The hydraulic pump operates at minimum pressure.

The controller monitors the supply water pressure until the pressure
gets to the water manifold pressure setpoint.
The setpoint is based on the pump model.
Stage 2: Remove air from the system
 The intensifier starts stroking.
 Pump Starting flashes on the screen at 1-second intervals.
 The intensifier pushes water through the system and pushes air out
through the bleed-down valve.
 Supply water causes the water pressure in the system to increase.
 The Supply Water Start Procedure timer expires.
 The bleed-down valve is open.
Stage 3: Charge the system
 The bleed-down valve closes.
 Countdown Starting flashes on the screen at 1-second intervals.
 The intensifier strokes to increase the water pressure in the system.
Stage 4: Pressure Increasing
 The target pressure increases to 690 bar (10,000 psi).
 Pressure Increasing flashes on the screen at 1-second intervals.

The intensifier strokes to increase the water pressure in the system.
