boost pump, and the low-pressure water. When the motor is at operating speed, the
intensifier strokes in pierce-pressure mode for a time that is set at the operator interface.
When the timer expires, the intensifier strokes in cut-pressure mode.
If the pressure control is set to pierce-pressure mode, the pump starts and stays in
pierce-pressure mode.
If the pump is in cooling mode, the intensifier strokes.
PUMP OFF
This turns off the intensifier, the boost pump, the primary motor, the low-pressure water, and
the cooling fan.
In air-cooled systems, it also turns off the fan motor starter and the cooling fan.
It is recommended that the pump not be turned off for stand-by status between programs or
jobs.
COOLING ON
If the pump is running, this turns off the intensifier. The pump runs at the minimum hydraulic
pressure (551.58 bar/8000 psi).
