1 FOREWORD
These instructions have been compiled to assist personnel responsible for the
operation and maintenance of equipment manufactured by Regulateurs Europa
Ltd.
Care has been taken to ensure that the equipment has been accurately
represented, but it should be appreciated that, with the continued progress of
design and the diversity of application, certain items may differ in detail.
It should be noted that these instructions are issued for general information and do
not constitute a specification of the equipment.
Whilst reserving the right to make any alteration in design which they may
consider advisable the manufacturers absolve themselves from making any such
alteration retrospective.
In addition to the information given herein, practical advice and assistance is
always available from the Customer Support Department at Regulateurs Europa
Ltd.

2 GENERAL USE
Before carrying out any repairs, adjustments or maintenance to any equipment
supplied by Regulateurs Europa Ltd, it is essential the following safety precautions
be observed.
2.1 General
The operator should take care to make themselves thoroughly familiar with the
operating principles, methods of adjustment and the dismantling and assembly
procedures (where applicable) concerning the equipment in use.
2.2 Product Condition
Before power-up ensure that the product is in a good condition and not damaged,
paying particular attention to the ICENIbus connectors on each side of the module
and the field wiring connectors at the top of the module. Ensure that any wires are
fitted securely into terminals.
2.3 Signal Connection
If the module requires configuration then ensure that any critical signals are
disconnected from the module until configuration of the module has been
performed. This will prevent unwanted or unexpected changes in signal polarity
from affecting other circuitry.
2.4 Module Damage / Repair
The Iceni modules are not repairable. Where damage is found that could
compromise the operation of the module, a replacement part should be sourced
from Regulateurs Europa Ltd.
Iceni module should be disposed via an approved disposal scheme suited to
electronic products and in accordance with local legislation.

3 PRODUCT OVERVIEW
3.1 Iceni Node
An Iceni node comprises of a master module, between one and sixteen signal
conditioning modules and at least one power supply module.
A typical Iceni node:
master signal conditioning modules power
module (x8 in this example) supply
module
According to the mix of signal conditioning modules, the Iceni node manages the
measurement and generation of electrical signals to/from sensors and field
devices. Information is exchanged with other nodes in a system via a field
communications network connected to the Iceni master module.

3.2 ICENIbus Interface
Iceni modules are designed to plug together to form a node. The connection
system used to join one module to another is called ICENIbus and is used to
transfer both data and power supply between modules.
All modules have a 10-way ICENIbus connector on both sides of the lower
housing, although for end modules (master and main power supply) one side
connector will be supplied fitted with a protective cover.

ICENI/AI-04
3.3 Field Wiring Interface
As standard, Iceni modules are supplied with screw-clamp field wiring connectors,
although cage-clamp variants are available as an option.
For ICENI/AI-04 there are four connectors marked 1-4, 5-8, 9-12 and 13-16 to
match the numbers marked on the Iceni housing. This arrangement identifies the
connector to its location on the module.
When fitted properly, the field wiring connectors are held securely in the module
housing. In order to remove a terminal, a small flat bladed screwdriver should be
inserted between the top of the connector and the module housing to enable the
connector to be carefully levered free. This will release the connector without
damage.

4 ICENI/AI-04 KEY FEATURES
The ICENI/AI-04 module is a component of an Iceni node and provides four
isolated input channels for monitoring field temperature sensors (fluids, bearings,
motor windings, etc.)
The ICENI/AI-04 module provides the following key features:
oFour sensor inputs, each configurable to support PT100, PT200, PT500 and
PT1000 type sensors (alpha = 0.00385).
oSignal fault indication via illuminated channel indicator on ICENI/AI-04 module
and on master module display.
oMeasured real world value (i.e. measured temperature) available to field
communications network and master module display.
oSignal health status available to field communications network and master
module display.
