Installation; Unit Location; Power Supply; Pressure Sensor Location - Ingersoll Rand X8I Mode D'emploi

INSTALLATION

It is recommended that installation and
commissioning be carried out by an authorized and
trained product supplier.

UNIT LOCATION

The X8I can be mounted on a wall using conventional
bolts. The X8I can be located remotely from the
compressors as long as it is within 330 feet (100 meters)
of cable length when connecting compressors directly
with ir-PCB's. When connecting the X8I over the RS485
communication network the distance is up to 4000 feet
(1219 meters) The X8I must be located within 330 feet
(100 meters) of the system pressure transducer.

POWER SUPPLY

A fused switching isolator must be installed to the main
incoming power supply, external to the X8I. The isolator
must be fitted with a properly sized fuse to provide
adequate protection to the power supply cable used (in
accordance with local electrical and safety regulations).

Ensure that the voltage select input is properly
jumpered for the incoming power. Default voltage
configuration is 230Vac.

PRESSURE SENSOR LOCATION

The system pressure sensor (P) must be located where
it will see the air pressure that is common to all of the
compressors.

Dry side pressure will be lower than the system
pressure due to pressure differential losses across air
treatment equipment. The nominal system pressure will
reduce as the air treatment differential pressure increases.

Equipment
Ensure each compressor is equipped with
independent excess pressure shutdown. An increase in
pressure differential across air treatment equipment can
result in excess compressor discharge pressure.
Regular routine monitoring of pressure differential
across air treatment equipment is recommended.
