On X4 Controllers equipped with either CO or
Dew Point monitoring, the following features
will be present:
1) Flow Control Dial
2) Air Flow Adjustment Eye
Four models of the X4 are available for a Stationary Air
compressor system:
The Basic controller has warning indicators for high
discharge air temperature and low oil conditions.
The CO Only controller has the same features as
the Basic controller but adds a monitor for high carbon
monoxide (CO) levels in the breathing air.
The Dew Point Only controller has the same features
as the Basic controller but adds a monitor for excessive
moisture levels (Dew Point or DP).
The Full Feature controller includes BOTH the Carbon
Monoxide (CO) monitor AND the moisture level monitor
(Dew Point or DP) along with warning indicators for high
discharge air temperature and low oil conditions.
It is the responsibility of the System Administrator
to inform the Operator what features are installed
and enabled and to train the Operator in their use. It
is the Operator’s responsibility to notify the System
Administrator of any alarms or shutdown warnings the
occur during the operation of the compressor system.
NOTE
If the CO or Dew Point monitor is not installed on
your system, the X4 Controller will display “N/A”
after the parameter on the LCD screen.
If monitored conditions are out of tolerance, the controller
emits a visual and audible alarm and will subsequently
shut down the compressor.
The controller allows the system to run in either AUTO
or MANUAL mode. In AUTO mode, the compressor
will automatically restart when storage pressure drops
approximately 500 psi below the maximum system
pressure. When in MANUAL mode, the compressor stops
after purging and must be restarted manually.
On compressor systems where the CO or Dew Point
monitors are not installed, it is also the responsibility
of the organization using this equipment to establish
procedures to assure the breathing air quality to
the end user in the time between the routine air
samples. Failure to establish procedures to monitor
the breathing air quality could result in undetected
problems that could lead to production of air that does
not meet the breathing air standards which could lead
to serious injury or death of the respirator users.
On compressor systems where the SCOTT CO or Dew
Point monitors are not installed or operational, it is the
responsibility of the organization using this equipment to
establish procedures to assure the breathing air quality
to the end user in the time between the routine air
samples. Failure to establish procedures to monitor the
breathing air quality could result in undetected problems
that could lead to production of air that does not meet
the CGA breathing air standards cited on Page 7 of this
instruction.
