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”.
13. Main Pressure Gauge – This gauge monitors the
system pressure while pumping material. The maximum
pressure rating is 3100 PSI ± 50.
