OPERATING AND MAINTENANCE INSTRUCTIONS
1 Machine Description:
The DPI Testing System is designed to carry out a series of testing protocols on components of the DPI device. The equipment tests four (4) parts that form the assembly of the DPI device. See Drawing 2-1for a top view of the equipment.
The equipment is designed to handle three (3) dose configurations:
• 100 µg – 7-, 14-, 30-, 60- and 120-count doses
• 200 µg – 7-, 14-, 30-, 60- and 120-count doses
• 400 µg – 7-, 14-, 30-, and 60-count doses
The equipment is designed to perform the following five (5) tests:
1. Dose hole alignment of lower subassembly
2. Snap force of the lower to upper subassembly
3. Insertion force of the dry desiccant into the overcap
4. Counter function with overcap (partial) and application and removal torque
5. Counter function with overcap (complete) and application and removal torque.
2 Parts of the Machine:
The DPI Testing System consists of four (4) independent testing stations:
• Station 1 – Dose Hole Alignment Test
• Station 2 – Snap Force Test
• Station 3 – Insertion Force Test
• Station 4 – Counter and Torque Test

Drawing 2-1 - Dry Powder Inhaler Testing System
1 Station 1 – Dose Hole Alignment
The primary function of Station 1 (Picture 2-1) is to check the lower subassembly’s dose hole size and alignment.
The Dose Hole Alignment Station includes the following components: lower subassembly, one (1) vision camera with light, a servo motor, a vision camera, and two (2) pneumatic cylinders.
2 Station 2 – Snap Force
The function of Station 2 (Picture 2-2) is to measure the force required to snap the upper subassembly to the lower subassembly.
The Snap Force Station includes the following components: lower subassembly, upper subassembly, and a servo press.
[pic]
Picture 2-2 - Snap Force
1. The operator manually places an upper subassembly onto a lower subassembly, aligning the parts properly.
2. These parts are then placed in the single tooling fixture (as shown in Picture 2-2).
3. The operator rotates the combined assembly until the window is in line with notch on nest.
4. A test is initiated by pressing one of the opto start buttons.
5. The light curtain is reset. The green light-stack light turns on solid.
6. A force-measuring servo press lowers a ram and snaps the upper subassembly and lower subassembly together. The peak force to snap the two parts together is recorded.
7. The green light-stack light turns off, indicating the operator must remove the part.
8. The operator places successfully tested parts back on the part tray. Rejected parts are placed in the reject bin.
3 Station 3 – Insertion Force
The primary function of Station 3 (Picture 2-3) is to measure the force required to snap the desiccant cartridge into the overcap.
The Insertion Force Station includes the following components: overcap, desiccant cartridge, and a servo press.

5. The green light-stack light turns off, indicating the operator must remove the part.
6. The operator places successfully tested parts on to a part tray. Rejected parts are placed in the reject bin.
3 Control Description
1 Machine Control
Allen-Bradley ControlLogix platform of programmable logic controllers (PLCs) and associated equipment are used on this machine. This platform was developed to integrate logic and motion; therefore, it was the preferred choice as the PLC for this machine.
Each test station has independent controls and light curtain guards. Therefore, they can be run independently.
Vision inspection and Optical Character Recognition is achieved by using Cognex In-Sight model 5100 camera systems.
2 Data Collection Computer
The machine server is a server member of the Schering-Plough domain server. It is mounted inside a lockable console.
All test results are stored on the machine server in a Microsoft SQL server database. When testing is completed on a particular lot, the database is archived to Schering-Plough’s secure server. Even if this data is successfully archived, it remains on the local server for 90 days before it is deleted.
3 Human-Machine Interface (HMI)
Allen-Bradley RSView software (Supervisory Edition) running on Dell workstations serves as the operator interface to the equipment. This includes the following functions:
• Manual buttons to initiate individual machine motions for testing and setup
• Diagnostics to alert the operator to problems that may prevent the machine from running/starting
• Disable and abort automatic cycles
• Printing of reports
• Calibration and maintenance alerts
Operation and Controls
1 Operator Interface Overview
Dell workstations with touchscreen monitors are the Human Machine Interface (HMI). These HMIs are used for machine control and adjustments.
The touchscreen monitors are mounted on ERGOTRON arms, which allow for horizontal, vertical, and swivel adjustment.
Operation of the DPI Testing System is controlled by RSView ME software via the Dell workstations with touchscreens and function control pushbuttons. The HMI includes screens that are used for station status displays, manual actions, station setup, and alarm handling. The HMI system on the DPI Testing System is based on Rockwell’s RSView Supervisory Edition Client.
RSView Supervisory Edition Server handles the system level user interface via a Windows-based PC.
2 HMI Overview:
[pic]
Picture 3-2 - Human Machine Interface
Screens appear as an integrated entity on the HMI. Each HMI screen is constructed of a base screen overlaid with the selected screen. The base screen contains elements that are present on all screens and serves the purpose of maintaining consistent presentation of common information, format, and function. The selected screen contains information related to its topic.
|IMPORTANT: After entering any numeric data on the HMI screen, always press the enter key. Data is not accepted until the enter key is pressed. |
1 Navigation Buttons
All screens on the HMI have navigation capability to go to another screen via touchscreen buttons located on the footer of each screen.
