LS400/LS500 PUMP — DIGITAL CONTROL PANEL COMPONENTS
Figure 6. Pump Digital Control Panel Components
1.
Emergency Stop Button – Press emergency stop
button to stop pump in an emergency. Turn knob
counterclockwise to disengage the stop button.
2.
Ignition Switch – Insert the ignition key here to start
the engine. Turn the key clockwise to the ON position,
then continue turning clockwise to the START position
and release. To stop the engine turn the key fully
counterclockwise to the STOP position.
3.
Digital Readout Screen – Displays and monitors the
various functions of the machine.
4.
Scroll Switch – Allows the operator to scroll the various
readout screens.
5.
Reset Switch – Allows the operator to reset the stroke
counter.
6.
Remote Cable Connector – Insert the remote control
input cable into this connector.
7.
Direction Control Switch – This 2-position switch
controls the direction of flow for any mix in the pump.
The 
leftmost  position sets the pumping direction to
forward and the 
rightmost position sets the pumping
direction to reverse.
8.
Pumping  Control  Switch – This 3-position switch
controls the pumping of the pump. The 
rightmost
position (REMOTE) is for use with the remote control
unit, the 
leftmost  position (LOCAL) is for normal
pumping operation, and the 
centermost position
(CENTER OFF) prevents pumping.
9.
Cylinder Stroke Control Switch   This 2-position
switch controls the pumping function. The 
leftmost
position (AUTOMATIC) sets the pump to 
automatic
cycling. Set the switch to this position for normal pump
operation.
The 
rightmost position (JOG) changes the pump from
automatic to 
manual cycling. This allows the cylinders
to be manually cycled using the 
Manual Cylinder
Jogging Switch.
10. Manual Cylinder Jogging Switch – This  2-position
switch allows the operator to manually jog the cylinders
to assist in clearing material line packs and is used to
test pumping pressure (See 
Initial Start-up Procedure
section of this manual for testing procedure).
The 
leftmost  position jogs Cylinder “A” and the
rightmost position jogs Cylinder “B”.
11. Stroke Volume  Control  Switch  –  Increases or
decreases the number of strokes per minute of the
pump.
12. Accumulator Pressure Gauge  This gauge monitors
the internal pressure of the Accumulator tank. Normal
internal pressure should read approximately 1750 PSI
during pumping.
13. Main Pressure Gauge   This gauge monitors the
system pressure while pumping material. The maximum
pressure rating is 4400 PSI ± 50.
