OPERATIONAL FUNCTIONS
STOP
To stop the X4I, press STOP. Dependent on the setup
and configuration of the X4I, the compressors will
function as follows:
•If parameter CF=X, then pressure regulation
control is automatically transferred back to each
compressor. The compressor(s) will continue to
operate using the pressure settings programmed
or set in the individual compressor controller(s).
•If parameter CF= , then the X4I will hold each
compressor in an offload state. If the
compressor is equipped with a main motor run-
on-time function the compressor will run offload
for a period of time and then stop in to a
“standby” or “auto restart” state.
The design of some air compressor control systems may
inhibit automatic transfer of pressure regulation control
to local operation mode. In this instance, the compressor
will not continue production of compressed air. Consult
the air compressor manual or your air compressor
supplier or specialist for details before installing the X4I.
START
To start the X4I press START. If the Prefill function is
enabled, and system pressure is below the set prefill
pressure, the system will enter Prefill mode for the set
Prefill time.
NOTE: The Default setting for Prefill is OFF.
See the section on Prefill in the Operator’s Manual
for more information.
To manually skip the Prefill function, press and hold
START for several seconds. When Prefill is complete, if
applicable, the X4I will enter normal operating mode.
The X4I will operate in accordance with the parameters
and options set in the active “Table”.
See the section on Tables in the Operator’s Manual
for more information.
Each compressor in the system must be started (running
or in a standby or auto restart condition) before X4I
control of the compressor can be established. The X4I
will not start a compressor that is in a stopped condition.

POWER FAILURE AUTO-RESTART
If the power failure auto-restart function is enabled, the
X4I will automatically start when power is restored after a
disruption or failure, if the X4I was in a ‘started’ state
when the power disruption or failure occurred.
NOTE: The Default setting for Power Failure Auto Restart
is ON.
10
NOTE: The X4I will not automatically restart if it was in a
stopped state when the power disruption or failure
occurred.
FAILURE MODE
If the X4I experiences a disruption to normal control, or
an X4I shutdown fault occurs, pressure regulation control
is automatically transferred back to each compressor.
The compressor(s) will continue to operate using the
pressure settings programmed or set in the individual
compressor controller(s).
RESET
To reset an X4I Alarm (Warning) or Shutdown condition,
press RESET. Compressor Alarm (Warning) conditions are
automatically reset when the condition has been resolved
and reset on the compressor. “Compressor Not
Available” (Shutdown, Trip) conditions are automatically
reset when the condition has been resolved and reset on
