A quick start tutorial will explain how to use the touchscreen.
Touch anywhere on the screen to go to tutorial screen 2. Touch
the
icon to exit the tutorial and go to the Home Screen.
Set the Time & Date and Alarm 1 & Alarm 2 settings because
they are set at the factory defaults. The Time & Date will only
need to be set once. The Alarm 1 & Alarm 2 settings may need
to be adjusted for each Job’s requirements. For asbestos
removal, the Alarm 1 & Alarm 2 settings should be in negative
units when used to monitor a negative (vacuum) containment
area. For positive pressure applications, use positive units for
the Alarm settings.
Note: The Alarm 1 & 2 settings and the Time & Date
are displayed in yellow on the Home screen until
they have been changed from factory defaults.
Normal Power-Up Sequence
A diagnostic test will automatically run and the Omniguard will then
immediately begin to monitor containment pressure. The status will
indicate START JOB. Touch START JOB to begin actively monitoring
a new job.
Note: If the Omniguard was actively monitoring a Job when
it was turned off, it will automatically resume monitoring the
current Job. POWER OFF followed by the time-stamp will
print. Otherwise AC MODE or POWER FAIL will print,
indicating that an AC power failure occurred. Either message
will be followed by the time-stamp.
Once the Omniguard is actively monitoring a Job, the status will
indicate WAITING FOR PRESSURE until the containment pressure
has reached the operating window. The Job Name, time-stamp and
Alarm settings will be printed.
Note: Logging and printing of monitored pressure readings
does not begin until the containment pressure has reached the
operating window and the status indicates NORMAL.
Reminder: Be sure the Alarm 1 and Alarm 2 settings are
correct for your job site requirements!
Once the containment pressure reaches the operating window (the
area between the Alarm 1 and Alarm 2 settings) the status changes
from WAITING FOR PRESSURE to NORMAL and a green border
will appear around the screen. NORMAL OP is then printed along
with a time-stamp.
The screen border will change from green to yellow and the status
changes to APPROACHING ALARM to warn of an impending
Alarm condition when the pressure is within 0.005”WC of the Alarm
settings.
Starting/Ending A Job
Pressing START JOB will not erase any previous job logs, nor will it
alter any other settings (such as the Alarm settings). The log for the
previous job can be printed at any time.
Note: It is a good idea to print a report of the previous
job before starting a new job. A report for the previous
job may be printed at a later time by touching
on
the Home screen, choose the report you want and touch
Print.
To start a new job --
1. If the Omniguard is not currently monitoring a job, the status will
indicate START JOB at the bottom of the Home screen. Touch
START JOB, then confirm you want to start a new job.
2. Enter the new Job Name, then touch
to save it and start
monitoring. The Job Name, time-stamp and current alarm settings
will be logged and printed.
To end the current job --
1. From the Home screen, touch in the upper left-hand corner
to go to the Main menu.
2. From the Main Menu, touch End Job, then confirm you want to
end the job by touching End Job again.
Example of Job Summary Report,
after End Job is pressed --
Alarm Settings Screen
Alarm 1 & Alarm 2 Settings: The operating window is the area between
the Alarm 1 and Alarm 2 settings. These settings can be set anywhere
within the operating range of the unit; +/- 0.250” WC in increments
of 0.005”WC. The Omniguard can also operate in units of mmWC or
Pascals. (See Pressure Units.)
