ACCUMULATOR POSITION MEASUREMENT
1-5-9.
Accumulator type blow molding machines require a position transducer to indicate the accumulator position.
The parison wall thickness pattern can then be programmed with direct reference to the accumulator
stroke of Shot Size.
If the DigiPackⅡis being installed on a continuous extrusion machine please go to the next section.
INSTALLATION REQUIREMENTS
1-5-10.
The position transducer is required to operate in a high temperature and vibration environment. In addition
the transducer must accommodate some mechanical miss-alignment without reduction of life and linearity.
Transducer installation designed to control and adjustment the alignment between the potentiometer and
the accumulator motions. The features are as follows:
1)
An accumulator driven bearing guided structure for the potentiometer drive arm
2)
Mounting provisions for the potentiometer on the same bearing guided structure, provisions for
adjustment to insure parallel motion of the potentiometer guide arm and potentiometer drive rod
3)
And a rod end bearing between the potentiometer drive rod and the potentiometer guide arm

How..to set up the..Digi pack 2 on machine
To set up the Moog DigiPack II on a machine, follow these key steps:
1. Installer Requirements: The installer must be familiar with electrical wiring, hydraulic plumbing, basic metal work, and have some understanding of the blow molding process. Use of test instruments like a digital voltmeter is also required.
2. Mechanical Installation:
- Install and adjust tooling and die gap actuators.
- Mount the servovalve and manifold.
- Install the hydraulic cylinder and ensure it meets customer specifications.
- Measure and set accumulator position.
- Ensure proper filtration and install filters.
- Connect the hydraulic power supply and follow startup instructions.
- Implement contamination control.
3. Electrical Installation: Follow the manual's guidance for electrical connections.
4. Software Update (if needed):
- Power off DigiPack II and remove the SD card.
- Save the “DIGIPK2.FWM” file to the SD card using a PC.
- Reinsert the SD card and power on the unit.
- Press “X10” and “Cursor Down” keys simultaneously during startup.
- Wait for the “Updating firmware……” message.
- Confirm update by checking the software version on the startup display.
5. Calibration and Setup:
- Set accumulator working stroke, shot size, and end position.
- Interface DigiPack II with the machine’s PLC for motion control.
Proper installation following the manual ensures reliable long-term operation.

The shot size is to short and the Digi pack to is not in command..
If the shot size is too short and the Moog DigiPack II is not functioning properly, turn the Entry Knob clockwise to increase the Shot Size value on the LCD display. Then press the Set button to make the change permanent.
