Introduction 2604 Controller

1-2 User Guide Part No HA026491 Issue 3.0 Apr-02

1. Chapter 1 INTRODUCTION

Thank you for selecting the 2604 High Performance Programmer/Controller.

This controller can be supplied or can be fully configured to be process specific.

It is important to note, therefore, that the actual displays shown in this guide

may not be identical to those shown on your controller.

This guide, therefore, is intended to describe the principle of operation and

installation of the controller, and is intended as a ‘Getting Started Guide’.

A detailed Engineering Handbook is also available, part no. HA026761, for those wishing to

configure and commission the controller.

1.1. WHAT IS 2604

The 2604 is a modular, fully configurable, high

accuracy, high stability temperature and process

controller which is available in a single, dual or

three loop format.

It is supplied in accordance with an ordering code

which can be found printed on a label on the side of

the instrument case. A description of the order

code is given in Appendix A of this guide and

should be checked with that shown on the label.

It has a dual 7-segment display of process value and

setpoint with a LCD panel for display of

information and user defined messages.. The user

interface is menu driven via the display and seven

front panel keys.

Figure 1-1: General View of 2704 Controller

Features include:

•Advanced ramp/dwell programmer with storage of up to 50 programs.

•Application specific controllers such as Carbon Potential, Humidity and Melt Pressure

•A wide variety of inputs which can be configured, including thermocouples, Pt100

resistance thermometers and high level process inputs.

•Each loop can be defined to be PID, On/Off or motorised valve position and can control

using a variety of strategies including single, cascade, override and ratio control.

•PID control outputs can be relay, logic, triac or dc with motorised valve position outputs

being relay triac or logic.

•Auto tuning and PID gain scheduling are available to simplify commissioning and

optimise the process

1.2. BEFORE YOU BEGIN

1.2.1. Unpacking

The packaging is designed to withstand reasonable transit shocks. It is suggested that each

item is unpacked carefully and the contents inspected for damage.

If there is evidence of shipping damage, please notify your supplier within 72 hours. The

packaging should be retained for inspection.

All packaging contains anti-static materials to prevent the build up of static which can damage

electronic assemblies.

1.2.2. Contents of Packaging

Each box contains the following parts:-

1. The 2604 controller fitted into its corresponding sleeve. Labels on the sleeve identify the

controller code, its serial number, and the customer reference number. These details

should be checked against your requirements before installing the unit into the panel.

2. Two panel retaining clips

3. Burden resistors for use with mA inputs

4. This User Guide

Please refer to Figure 1-2 showing a general view of the controller.

1.2.3. Does the Controller Match the Process?

Every controller is supplied with a specific hardware configuration to match the process which

it is designed to control. For example, there are five ‘slots’ which can contain different plug

in modules. These are defined by a hardware code as shown in Appendix A. Before installing

the 2604 controller check the label on the side of the instrument against the instrument coding

given in Appendix A for correct type.

Where possible the controller is supplied with its software configured to match the process.

This is defined by a quick start order code given in Appendix A. This should also be checked

on the instrument label to ensure that the controller is suitable for the process to be controlled.

1.3. OPERATOR INTERFACE - OVERVIEW

The front panel of the 2604 consists of two 5 digit numeric displays, one alpha numeric LCD

panel for display of messages and other information, eight LED staus indicators and seven

operator push-buttons. See Figure 1-3 below.

•The display is used to show the process conditions.

•The seven operator buttons allow adjustments to be made to the controller.

1.3.1. LED Status Indicators

Indicator Function

AUTO The selected loop is in automatic (closed loop) control

MAN The selected loop is in manual (open loop) control

LP1

LP2 Indicates which control loop is selected

LP3

AUX Indicates that the selected loop has a second control function.

For example, if a loop is configured as cascade, ratio or override then

a second press of the loop button will cause the AUX indicator to

illuminate together with the loop indicator.

RUN Indicates a program is activated

HOLD Indicates a program is held at its current levels

ALARM BEACON This is a red LED which will flash when any new alarm occurs. It will

be accompanied by a message displayed on the lower readout. The

beacon will be permanently lit when an alarm is acknowledged but is

still present. See Chapter 7 ‘Alarm Operation’ for further details.

STANDBY

BEACON This is a green LED which will be lit when the controller is in Standby

mode. When the controller is in standby mode all interfaces to the

plant are switched to a rest condition. For example, all control outputs

= 0.

When this beacon is lit the controller is no longer controlling the

process.

This beacon will be lit when:-

•The controller is in configuration mode

•Standby mode has been selected through the user interface or via

an external digital input

•During the first few seconds after start up
