A potentiometer measures the accumulator position and controls the vertical axis of the program display.
The operator can also set the accumulator working stroke, Shot Size, and the desired position at the end of
the accumulator push out, Cushion the DigiPackⅡalso provides interfacing signals for these functions with
the machines PLC, which then controls motion of the accumulator.
Set up of the die gap tooling and tooling die gap actuator has been easier with simplified detection of
mandrel die zero.
Successful performance of the DigiPackⅡdepends a great deal upon how well it is installed on the machine.
By following the instructions contained in this manual it will be possible to easily install this system and
obtain many years of trouble free operation.

WHO CAN INSTALL THE DigiPackⅡ
The installation of the DigiPackⅡcontrol system requires the installer to be familiar with electrical wiring,
hydraulic plumbing and basic metal working. The calibration and start up of the finished system requires
some understanding of the blow molding process and use of test instruments such as a digital voltmeter.
The plumbing, wiring and bracketry should not be difficult. Most molding shop maintenance men who are
familiar with blow molding machines will have little difficulty with the help of this manual.
The system can be satisfactorily calibrated to the machine and started up without assistance or special
equipment by following the instructions in this manual.
