Chapter 1 Introduction The AirSentry II Mobile AMC System is the first truly mobile system for monitoring airborne molecular contamination (AMC) in cleanroom environments and within process equipment. Mobility plays an important part within a strategic AMC monitoring program, allowing potential contamination sources to be quickly and precisely located and quantified, regardless of location.

Powering-On/Off the AirSentry II Mobile AMC System Chapter 4 : Operation Powering-On/Off the AirSentry II Mobile AMC System To power on the mobile system’s UPS, main and compressor power must be turned on in sequence: 1. Plug in the cart to AC power (unless in Transport Mode). 2.
Chapter 4 : Operation Powering-On/Off the AirSentry II Mobile AMC System 3. Turn on the main power switch. The main power switch is located on the main board recessed behind the cover. • Power is distributed through the Power Distribution PCB (called PDB throughout this document).
PDB Alarm Functionality Chapter 4 : Operation PDB Alarm Functionality The PDB is enabled to detect fault states indicating CDA compression system failures (e.g., pneumatic system leaks, compressor issues, pressure transducer malfunction) and PCB circuitry failures (e.g., thermal breaker trip if the board temperature exceeds 50 °C, other circuitry failures).
Chapter 4 : Operation Low Vibration Mode 4. In this mode, the compressor will not cycle, and CDA is supplied by the external facilities. This minimizes the internal vibration of the system. 5. To return the instrument to ‘Pump’ mode, reverse steps 1-3. NOTE: When using HOUSE CDA ensure the regulator on the air dryer is set to maximum by adjusting the regulator valve to fully open (counter- Figure 4-3...
Chapter 4 : Operation Transport Mode Transport Mode In transport mode, the mobile cart supplies its own CDA via the internal CDA System. The sample nozzle will either be exposed to ambient air, or if sampling is not desired in the transport zones, the user can connect the Zero-gas line (internal to the mobile cabinet) to the sample cross-connect to send pure CDA back through all sensor sample inlets.
Performance Specifications Chapter 4 : Operation Performance Specifications The limits of detection (LDL) for AirSentry II analyzers when used in conjunction with the AirSentry II Mobile AMC System are as follows: Table 4-2 LDL of ASII sensors in the mobile cart configuration AirSentry II AirSentry II AirSentry II...
Chapter 4 : Operation Calibration Protocol Calibration Protocol Before the AirSentry II analyzers can be used to monitor cleanroom locations for the presence of AMC, they must be calibrated for zero sample and for overall measurement span of a known concentration. A factory calibration has been performed prior to shipment on each analyzer at Particle Measuring Systems.
Chapter 5 Maintenance Preventative Maintenance (PM) and General Best Practices Filter Elements • Coalescing and Particle Filter Changes - The coalescing filter extracts aerosol water, and other aerosol contaminants, whereas the Particle filter removes airborne particulates from the ambient air produced in the system CDA. Depending on the quality of the ambient air these filters may need to be replaced more or less frequently.
Chapter 5 : Maintenance Preventative Maintenance (PM) and General Best Practices CDA System, Vacuum Pumps, Compressor The CDA system will extract water from ambient air and accumulate condensed water at volumetric rates depending upon local humidity levels. The CDA system must release this pure water condensate by way of an electronic drain valve with opening frequency and duration settings (see Figure 5-2).
Preventative Maintenance (PM) and General Best Practices Chapter 5 : Maintenance Figure 5-2 Electronic drain valve (arrow) and condensation bottle (circled) The vacuum pump requires service every 6 months. It is recommended that a 6-month PM kit is kept in stock at all times. The compressor requires service every 6 months.
