S03 – 01/02 I/O Box Monitoring
This parameter determines if the X8I will monitor the
selected I/O Box and display any 'Fault' detected on the
I/O Box inputs; dependant on I/O Box set-up. The default
setting for this parameter is
monitoring is disabled) The values for this parameter are:
= Disabled
= Enabled
Refer to I/O Box manual for details.
S03 – BT Communications Timeout
This parameter determines the Communication Broadcast
Timeout between the X8I and the I/O box. If the I/O Box
fails to communicate on the RS485 network within the
set 'Communications Broadcast Timeout' (BT), the X8I
will display an I/O Box RS485 communications Error.
The default setting for this parameter is 60 seconds. The
values for this parameter are:
"10 to 300" the number of seconds
The general operation of the selected I/O Box is also
monitored.

S04 - 1O Pressure Sensor Offset
This parameter will be the minimum value of the pressure
transducer, 0 PSI, 0 BAR, or 0 kPA. It can also be used to
create an 'Offset' if there is a difference in the zero value
being displayed. The default setting for this parameter is 0
PSI. The values for this parameter are:
"0" when using the minimum value of the pressure
transducer range
A value greater than or less than 0 if the display
does not read 0 or when using an Offset pressure
transducer (an example of an Offset pressure
transducer would be one where the range was minus
PSI (-25) to a positive PSI (200).

232
The pressure transducer must be vented to
atmosphere when setting the 0 or offset.
S04 - 1R Pressure Sensor Range
This parameter will be the maximum range of the
pressure transducer, 232 PSI, 16 BAR, or 1600 kPA. It can
also be used to create an 'Offset' if there is a difference in
the range value being displayed. The default setting for
this parameter is 232 PSI. The values for this parameter
are:
"232" when using the maximum value of the
pressure transducer range
A value greater than or less than 232 if the display
does not read 232.
The pressure transducer must have a known,
accurate pressure applied to it when changing
this value to a value other than 232.
Pressure Sensor Calibration Procedure:
a) Offset: Expose the sensor to atmosphere and adjust
the 'offset' setting (if necessary) until the detected
pressure display shows 0 PSI (0.0 BAR).
b) Range: Apply an accurately know pressure to the
pressure sensor and adjust the 'Range' setting until
the detected pressure display matches the applied
pressure. An applied pressure equal too, or greater
than, the nominal system working pressure is
recommended.
The detected pressure is displayed with the
calibration menu item and will change to match the new
calibration setting as the setting is adjusted.
There is no need for the applied pressure to be static;
it can be dynamic and changing. This enables calibration
to be carried out on a fully operational system where
changing system pressure can be accurately verified from
another source.
Correct pressure sensor set-up and calibration
is critical for successful system operation. It is
recommended that pressure sensor calibration is
examined, and adjusted if necessary, annually or a pre-
determined routine periodic basis.
