COMPRESSOR IDENTIfICATION
Each compressor connected to the x8I or x12I will have
a unique assigned compressor identification number;
starting at compressor 1 increasing sequentially to the
number of compressors connected to the x8I or x12I.

X8I & X12I CONTROL KEyPAD fUNCTIONS
Stop:
To stop the x8I or x12I press Stop.
The x8I or x12I will respond dependant on the setup of
item ‘CF’ in menu S02:
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).
The x8I or x12I 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 / specialist for details before
installing the x8I or x12I.
START:
To start the x8I or x12I press Start.
If the ‘Start Function’ is enabled there will be a period of
time before any compressor is requested to load.
Start Function
To manually skip the Start function, press and hold
Start for several seconds.
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.
Prefill
To manually skip the Prefill function, press and hold
Start for several seconds.
When Prefill is complete, if applicable, the x8I or x12I will
enter normal operating mode.
The x8I or x12I will operate in accordance with the
parameters and options set in the active ‘Table’.
Tables
Each compressor in the system must be started
(running or in a standby or auto restart condition) before
x8I or x12I control of the compressor can be established.
The x8I or x12I 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 x8I or x12I will automatically start, when power is
restored after a disruption or failure, if the x8I or x12I was
in a ‘started’ state when the power disruption or failure
occurred.
The x8I or x12I will not automatically restart if the x8I or
x12I was in a stopped state when the power disruption or
failure occurred.
failure Mode
If the x8I or x12I experiences a disruption to normal
control, or an x8I or x12I 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 x8I or x12I 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 the compressor; and the compressor has
been restarted.
