4. COMMISSIONING
4.1 Commissioning Procedure
Commissioning Procedure
It is recommended that an authorised and
trained product supplier carry out
commissioning.
4.2 Physical Checks
Before applying power to the CX Box ensure
that the power supply connections are correct
and secure and that the operating voltage
selector is set correctly for the power supply
voltage in use; 115Vac or 230Vac (+-10%),
50/60Hz; see ‘Installation’.

General Checks:
Check and ensure all connections from remote
sensors or devices, and other connections,
are correctly installed and secure.
Close the front panel of the CX Box and apply
power.
Installation
Switch on the power supply to the CX Box.
The control program identification will be
displayed for a short period followed by the
normal operational User display.
4.3 Management System
For each compressor connected to the
Metacentre management unit using a CX Box,
ensure the connection type for the compressor
is defined as “I-485” for load/unload, or “V-
485” for regulating type, (RS485 network
communication) in the Metacentre
management system configuration.
Each compressor connected to a Metacentre
management system must be assigned a
unique compressor identification number (1 to
12). This number will be the ‘network address’
number for the compressor.
The number should be clearly marked on the
compressor for identification purposes.

4.4 Delivery Pressure Display
Check the displayed delivery pressure. If the
pressure is incorrect, or inaccurate, check the
type and range of the sensor and carry out the
pressure sensor commissioning and
calibration procedure.

4.5 Pressure Set Points
Set the local operating pressure set points to
suit system requirements when the CX Box is
functioning in local mode.

S01-PL
Low Pressure Set Point
For variable speed or variable regulation type
compressors the ‘PL’ lower pressure set point
will be the ‘Target’ pressure.
