1. Introduction
This supplement is intended to be additional information to that contained in the standard Nexus
Installation and Commissioning Bulletin. This document details the wiring configurations for the
Type2 Oxygen probe system. The Type2 component system will replace the original system by
March 31st, 2017.
The Type2 probe system employs a probe controller and trim interface, model NXO2TRIM, with
probe models NX6083-1, NX6083-2 and NX6083-3.
CAUTION

Unlike the NXO2INT, which is Line voltage supplied, the
NXO2TRIM only requires CANbus power 24V.
Connection of Line voltages to the NXO2TRIM will damage the
product beyond repair.

The interconnection system between the NXO2TRIM and the
NXPK224455-56-57probes is considerably different to the wiring
system between the NXO2INT and the NXO2PK-x probe
Installation and Wiring.
1.1 Installation.
1.1.1 Oxygen probe.
The NXPK224455-56-57 oxygen probe is available in the same sample tube lengths as the NXO2PK
probes and is designed for use with the existing mounting flange system.
1.1.2 Oxygen probe interface.
The NXO2TRIM oxygen trim interface enclosure has different dimensions and mounting points,
compared to the original design. The following drawing gives the dimensional information and the
details required to fix the interface to a wall or panel surface.
