28 RS485, X06 | Ingersoll-Rand X41 specs

AUXILIARY OUTPUT (OPTION)

The X4I is equipped with a remote relay contact output at terminals 33 and 34 (X08).

The function of the output is menu selectable and can be adapted for differing application requirements.

Auxiliary Output Circuit

The remote output relay contacts are rated for 240V “CE” / 115V “UL” @ 5A maximum.

RS485 COMMUNICATIONS

The X4I is equipped with an RS485 network communications capability using the proprietary Multi485 protocol.

This can be only used for remote connectivity to optional X4I expansion networked units and modules with proprietary Multi485 communications capabilities.

RS-485 Connection Circuit

anomaly that is difficult to diagnose. To avoid this possibility, always use shielded cables, securely bonded to a known ground at one end. In addition, give careful consideration to cable routing during installation.

•Never route an RS485 data communications or low voltage signal cable alongside a high voltage or 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.

•If it is necessary to follow the route of power supply cables for a short distance (for example: from a compressor to a wall along a suspended cable tray), attach the RS485 or signal cable on the outside of a grounded cable tray such that the cable tray forms a grounded electrical interference shield.

•Where possible, never route an RS485 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.

RS485 data communications and other low voltage signals can be subject to electrical interference. This potential can result in intermittent malfunction or

SECTION 5 — ASSISTANCE

Contacting Technical Support Services or Service Bulletins listed on the IR ServiceNet can provide further assistance if there are other questions or concerns during Installation and Start-up. Also, additional Application and Compressor Interconnect Guides will be posted and available on the IR ServiceNet as they are developed and created.

SECTION 6 — X4I OVERVIEW AND INTERCONNECT DRAWINGS

The following pages are to assist with the connection of the X4I to variety of Ingersoll Rand Compressors. These drawings are for Guidance Only; connections may differ with date, model, type, variant, special, custom or concession builds. This information is intended to be used in conjunction with the compressor’s original control circuit diagram.
