litres)
3. Recirculation Switch.
Turn to right to run the machine in recirculation mode (‘on’). Turn to left to stop
machine running in recirculation mode. (‘off’)
4. Pump Speed Pressure Gauge
Measures air pressure being sent to the resin pump air motor.
5. Pump Speed Pressure Regulator
Adjusts air pressure fed to the resin pump air motor, with reading shown on pump
speed pressure gauge.
6. Start Button (PDC machines only)
Begins machine operation. Will only operate when resin and catalyst recirculation
valves are in the inject position.
7. Air Purge Switch. (pull to operate)
Air purges excess resin\solvent from the injection head. Operates until pushed back
to stop.
OPTION: MPG Control Unit (automatically controls pump speed –
see Appendices)
8. MPG Preset Level Gauge
Indicates the maximum injection pressure selected by the operator
9. MPG Preset Regulator
Adjusts maximum injection pressure, with reading shown on MPG preset level
gauge.
10. Pump Signal gauge
Indicates pressure signal being sent to resin pump auto regulator. The lower
the pressure, the slower the pump speed.
11. Solvent Flush Button.
Activates the machine solvent flush cycle for approximately 30 seconds.
12. Mould Vacuum Level Gauge
Indicates level of vacuum achieved by the internal vacuum generator. With perfect
sealing of vacuum cavity, levels of -0.8 to -0.9 bar can be achieved.
13. Mould Vacuum On/Off.
Switches vacuum on/off. (Switch down for ON). Vacuum connection point is located
on rear of cabinet.
14. Mould Vacuum Isolator.
Isolates the vacuum generator from the remainder of the machine enabling air tight
vacuums to be held and read with the vacuum generator switched on or off. ( Switch
horizontal for isolate.)
15. Emergency Stop Button.
Removes all air pressure from the machine and deactivates the pull ‘on’ switch.
