EN
The Xe-70M controller is designed to interface to an Ingersoll Rand X-Series
System Controller using Belden 9841 or equivalent RS-485 cable. In order
to connect to the network, the cable must be connected to port X04 on the
controller as shown in the diagrams below. Note that up to 8 (X8I) or 12 (X12I)
devices can be daisy chained together in an X-Series network.:

RS-485 Network

RS-485 data communications and other low voltage signals can be
subject to electrical interference.
This potential can result in intermittent malfunction or anomaly that is
difficult to diagnose. To avoid this possibility always use earth shielded
cables, securely bonded to a known good earth at one end. In addition, give
careful consideration to cable routing during installation.
1. Never route an RS-485 data communications or low voltage signal
cable alongside a high voltage 3- phase power supply cable. If it is
necessary to cross the path of a power supply cable(s), always cross at
a right angle.
2. If it is necessary to follow the route of power supply cables for a
short distance (for example: from a compressor unit to a wall along a
suspended cable tray) attach the RS-485 or signal cable on the outside
of an earthed cable tray such that the cable tray forms an earthed
electrical interference shield.
3. Where possible, never route an RS-485 or signal cable near
to equipment or devices that may be a source of electrical
interference (for example: 3-phase power supply transformer, high
voltage switchgear unit, frequency inverter drive module, radio
communications antenna).

RS-485 Address Selection

Each compressor connected to the network will have a unique assigned
address, starting at compressor 1 increasing sequentially to the number of
compressors connected to the network.
The RS-485 address for each compressor is set on the General Settings Tab,
Page 7. The controller's default RS-485 Address setting is 1
Additionally, the active protocol must be set to Airbus485.

Enabling System Control Capabilities

In order to communicate properly with the X-Series system controller, the
Xe-70M must have the following setpoints correctly set.
On the Operator Settings tab, page 3 (Fixed Speed) or page 2 (Variable
Speed).
Verify that the COM control setpoint is enabled (Checkbox is filled in) as
shown below. If this setpoint is not selected, the system controller will be
unable to load or unload the machine.
Additionally, for fixed speed machines, make sure that the Enable Auto-
Restart setpoint is enabled (checkbox is filled in) or the compressor will
continue to run when unloaded by the system controller.
Figure 15
After the address and COM control have been set, be sure that Integral
Sequencing is disabled by navigating to Integral Sequencing, page 1 and
verifying that the Integral sequencing setpoint is disabled (checkbox not
filled in) as shown below:
Figure 16
Once these setpoints are correctly set and the machine is started locally, the
system controller should see status information from the compressor and be
able to take control.
