MAGNUM VENUS PLASTECH Innovator Megaject Manual 22
Prior to and during operation in injection mode, use the pump pressure regulator
and gauge to suitably adjust the air pressure supply to the pump and control the
pump speed.
Set the MPG set-pressure to the required pressure. Once the injection has
begun, the pump will stop running when the fluid pressure at the injection head
exceeds this setting. When the injection line pressure reduces below the MPG
set-pressure, the machine will continue to inject.
Adjust the predetermining counter to set the number of required pump strokes for
the injection. See figure 3.2 for an overview of the predetermining stroke counter.
To change the preset count, press and hold the white button with arrow decal
while pressing one of the black buttons under the preset count corresponding
with the digit to be modified.
Figure 3.2 – Predetermining counter
NOTE: The machine cannot be started in inject mode, if a previous injection
has stopped automatically when the shot count has been reached and the
stroke count has not been reset. Press the reset button on the predetermining
counter to reset the count and allow the machine to be started.
Press the inject button to start the machine in inject mode. The machine can not be
started in inject mode if it is operating in recirculation or flush modes. The injection
head will open, the TAS signal will pressurize and the pump will run. To stop the
machine and leave inject mode, press the stop button. If the predetermining counter
reaches the user set shot count, the machine will stop automatically.
If a PPVS sensor is being used the pump will stop when the mould pressure reaches
set-point. When the mould pressure drops to an acceptable level, the pump will run
once again.
