3.2 Operator Console
Operator interface with the SL-IV Waterjet Pump is through the operator’s
panel. The panel consists of the emergency stop (E-Stop) palm button START,
STOP, control power RESET pushbuttons, and indicator lights.
All electrical power to the SL-IV pump passes through the main disconnect,
controlled by the panel disconnect handle on the enclosure.
The following shows the layout of buttons and lights of the operator’s console
for the waterjet pump.

out the E-STOP, press the CONTROL POWER ON button to power up the
operator’s console. When the white CONTROL POWER ON light is lit the
24vdc control power is ON, and the pump can be started.
• Emergency Stop (E-STOP) (Item 1): Push in to stop pump. The E-STOP
button causes the following actions:
Electrical control power is shut off and the electric motor, hydraulic
pumps and intensifier assembly stop.

handle arrangement is intended to remove power from the electrical circuits
whenever the electrical enclosure door is opened.
