Perform System Service
Record Air Sample Date
and Calibrate Optional CO Monitor
To Record the Current Air Sample Date
1. Turn the external power source ON (wall-mounted
switch).
2. After the X4 Controller completes the system boot,
the display will say, “Press F2 Button Below to
Begin.” Press the F2 key directly below the X4
Controller digital display.
3. The display will show the current Service Due dates
and say, “Push Operate, Info, or Service.” Press

Overrides
The OVERRIDE capability is password protected and
may be DISABLED or ENABLED as determined by the
System Administrator who has the responsibility for main-
tenance of this equipment. The X4 Controller includes
limited shutdown override capability for high dew point,
high air temperature, high carbon monoxide levels, and
low oil level or pressure. Override allows the operator
to continue running the system in an out-of-tolerance
condition up to a maximum preset tolerance, or for one
hour, whichever occurs first.
The System Administrator must decide whether to DIS
-
ABLE or ENABLE the Override function.
Disabling the Override function assures the System Ad
-
ministrator that the breathing air produced by the system
will always fall within the established limits.
Enabling the Override function permits the Operator to
continue producing breathing air in the event of a life
threatening emergency where breathing air is required
and it is determined to accept the associated risks.
To Enable/Disable the OVERRIDE Feature
1. After Password section, the display will tell you
whether the OVERRIDE Feature is ENABLED or
DISABLED, and ask you if you want to change
the setting. The factory default setting is for the
OVERRIDE Feature to be DISABLED.
2. If you select YES (F1 button) the setting will be
switched to the opposite setting: from ENABLED
to DISABLED, or from DISABLED to ENABLED.
3. If you select NO (F3 button), the setting will stay as
it was originally displayed.
4. The X4 Controller will exit the Modify System
Settings and return the display to the start-up screen
that says “SCOTT Safety, 800-247-7257, PRESS F2
BUTTON BELOW TO BEGIN” as when first starting
the compressor system.
ONLY use the system override capability in the event
of an extreme emergency, or to save a life. During
an override condition, the operator must monitor the
system at all times. Operating the system beyond
factory-set parameters may lead to irreparable
component damage, and/or personal injury in the
case of system failure.
