Installation of the ionization system consists of conduit
bars attached to the ceiling of the room with stainless
steel brackets. These brackets attach to standard 2'
x 4" drop ceiling frames with or without HEPA filters.
The brackets and hangers are mounted to allow the
changing of lights and filters with minimal interference.
Zone Monitoring and Feedback
Each IRIS power supply incorporates 3 external sensors
to provide feedback to monitor stability of each zone.
Each sensor is assigned an alarm threshold. The
stability of each zone is controlled by the set duration
of power to each emitter. During the initial calibration
process, the power state is adjusted manually via the
TEAM5 IRIS Client Software while monitoring the work
environment with a Charge Plate Monitor until the
desired conditions are achieved. The duration of each
power state is recorded and saved during calibration.
These values are then used by the client computer to
control the power supply during normal use.
A sensor alarm is triggered if the sensor or power
values deviate from the saved calibration value by more
than the selected alarm range percentage. A “soft
alarm” alerts the system operator of the issue without
turning off the IRIS system. A “hard alarm” alerts the
system operator of the issue and turns off the IRIS
power supply. A tolerance threshold can be set to alarm
whenever the room system’s performance shifts too far
from its calibrated values. Sensors may be disabled
due to unordinary maintenance or activity in clean room.
Maintenance
Periodic maintenance including general cleaning,
emitter pin cleaning and recalibration may be necessary.
All power supplies must be turned off before any
maintenance procedures are taken. The conduits and
housings may be wiped clean using an all purpose
cleaner (make sure that all cleaners used are consistent
with requirements of the controlled environment/
cleanroom and ESD Protected Area). The emitter
points should be cleaned using a swab dampened with
Isopropyl.
TEAM5 IRIS Client Software
The IRIS Power Supply is controlled by a serial
communication line hard wired to the IRIS Tablet PC
with TEAM5 IRIS Client Software. TEAM5 IRIS Client
Software monitors and displays the feedback from each
of the three sensors and the high voltage output from
the power supply. TEAM5 IRIS Client Software is used
to set calibration profiles. A “Factory Default” profile will
be set at the time of the initial install of IRIS. Additional
profiles may be added and saved.

TEAM5 IRIS Server Software
TEAM5 IRIS Server Software allows for each zone
to be monitored remotely. TEAM5 IRIS Client and
TEAM5 IRIS Server communication takes place over
a local area network (LAN). Multi-zone power cycle
synchronization allows multiple zones in the same room/
area to be coordinated for optimal performance.
Design and Installation Quotes
EMIT includes application, engineering and sales
consulting with each IRIS installation. Each IRIS is
designed to provide a solution for particular needs of
a controlled environment. This includes accurately
estimating the cost (purchase, installation, and
maintenance) and layout of the system. With the quote,
EMIT will provide layout drawings, system specifications
and certifications, detailed parts lists and installation
project plans. EMIT works directly with its Chino, CA
factory to coordinate delivery schedules and installation.
IRIS support is provided throughout its ownership.
