NOTE: The control circuits will remain pressurized when the E-Stop is
activated. Use the isolation valve on the rear of the control box to shut off
the air supply to the machine if required. After isolation, residual air
pressure may remain in parts of the control circuit.
To de-activate the E-Stop, twist and pull to release.
Flush – Press the flush button to clean the injection head. The operator cannot
initiate a flush when the machine is in injection mode, therefore accidental
flushing of the system into a mould during an injection is not possible.
The flush system has an automatic timer function that will stop the flush cycle
automatically. The default duration of the flush is set between 30-60 seconds
during manufacture; however this can be adjusted by the user if required (see the
“Control Box Configuration” section).
The flush cycle can be stopped at any time by pressing the stop button.
NOTE: Before the flush button is pressed, ensure that the outlet from the
mixing head is directed to a suitable waste container.
Flush Timer Adjustment - The flush timer duration can be increased or
decreased by adjusting the flush timer restrictor. This controls the rate of airflow
out of the timer circuit reservoir, and the speed that the pressure falls in order to
actuate the automatic flush stop valve.
To set the timer, simply adjust the restrictor and then time the flush cycle.
Continue this procedure until the desired flush time is obtained. Times of over 60
seconds are achievable with this circuit.
See the “Control Box Configuration” section to identify the location of the flush
timer restrictor in the control box.
NOTE: If the restrictor is fully wound in, air flow will be blocked and the
timer will not operate. This can be used to disable the automatic timer if
required.
Prime – The Prime button is used to activate the pump with out the unit being in
Recirculation or Injection mode – with both the recirculation and injection guns
closed (prime fluid pressure). Prior to and during operation in prime mode, use
the pump pressure regulator and gauge to suitably adjust the air pressure supply
to the pump.
To operate the machine in prime mode, press and hold the prime button. The
pump will run with both the injection and recirculate guns closed.
