How do I set-up and operate my Automatic model 100Xs/100Xp

Introduction

The Automatic configuration is designed to integrate with a customer-designed automated PLC-production line

Setting up for Automatic Mode

For general setup instructions see “How do I Set-up and Operate my Standard model 100Xs/100Xp”

Interface Ports

USB Port:

Port connection requirements are 9600, N, 8, 1 (9600 baud, Non-parity, 8 bits & 1 stop bit). Drivers can be downloaded from http://www.ftdichip.com/Drivers/D2XX.htm. The device name is FT232R. For the driver installation, follow the instructions for your operating system at http://www.ftdichip.com/Documents/InstallGuides.htm.

 PLC Control Port:

A 7-pin circular connector. The mating connector is manufactured by Hirose Electric Co Ltd (Part Number RM12BPE7PH(71))

• “External Start” starts an instantaneous test or a routine during startup
  Note: the electrical pulse applied to the “External Start” input must last at least 300ms
• “Ready” indicates that the unit is ready to start a new test
• “Pass” indicates a passed test
• “Fail” indicates a failed test
• “Fault” indicates a non-calibrated state for the system when coupled with the Cal Mode status indicator or a fault
• “Cal Mode” indicates when a calibration routine is taking place

 Auto Port:

A 4-pin circular connector. The mating connector is manufactured by Hirose Electric Co Ltd (Part Number RM12BPE-4S(71)).

• “Pen Cal” is used by the PLC to request a Penetration Calibration routine
  Note: the electrical pulse applied to the “Pen Cal” input must last at least 300ms
• “Auto Select” enables the automatic mode for the unit
  Note: to enable automatic mode, 24VDC must be connected between the “Auto Select” input and the ground at all times. The voltage must be applied prior to powering on the unit.

Accessories Power Port:

A 4-pin circular connector with bayonet lock. Provides 24VDC power supply for ATI-designed accessories such as the Local Exhaust Module.

Accessories Data Port:

An RJ-45 connector. Provides a communication interface for ATI-designed accessories.

Aerosol and Pressure Lines Connections

The Automatic model has two pressure ports and two aerosol ports located at the back of the unit.

• “PH1” connects to the upstream side of the filter under test
• “PL1” connects to the downstream side of the filter under test
• “SUPPLY 1” connects to the upstream side of the filter under test
• “RETURN 1” connects to the downstream side of the filter under test

Command Sequences

Warm-up Sequence:

During warm-up, all interaction between the operator and the unit takes place on the touch screen.

Setup Sequence:

During setup, interaction takes place via a Human-Machine Interface (HMI). Once a sample is loaded, the “External Start” signal must be applied to initiate each test, in the following order.

• Gravimetric Test
• LSC Sensitivity Test
  Note: the test fixture must not contain any filter or assembly during the LSC Sensitivity Test.
• Pen Cal

Operation Sequence:

During operation, the PLC or Automated Production Line is responsible for loading and unloading the test fixture, ensuring the test fixture is properly closed, sending the “External Start” signal to initiate a test, and opening the test fixture and removing the filter afterward. Upon completion of the test, the machine will enable the “Pass” or “Fail” status line depending on the test outcome for the duration of the “Open Time” setting. Once the “Ready” status line is enabled, the machine is ready for the next test.

Pen Cal Sequence:

Called by sending a momentary voltage pulse to the “Pen Cal” input of the Auto Port.  Note: the test fixture must remain empty during the Pen Cal operation.
