INTRODUCTION

Models 2408 and 2404 are high stability, temperature or process controllers with self and

adaptive tuning. They have a modular hardware construction which accepts up to three plug-

in Input/Output modules and two interface modules to satisfy a wide range of control

requirements. Two digital inputs and an optional alarm relay are included as part of the fixed

hardware build.

The instruments are available as:

•standard controllers - which include a basic 8-segment programmer

Models 2408/CC and 2404/CC

•setpoint programming controllers: Models 2408/CP, P4, CM and

2404/CP, P4, CM

•motorised valve controllers - which include a basic 8-segment programmer

Models 2408/VC and 2404/VC

•setpoint programming motorised valve controllers: Models 2408/VP, V4, VM and

2404/VP, V4, VM

Before proceeding, please read the chapter called, Safety and EMC Information.

Controller labels

The labels on the sides of the controller identify the ordering code, the serial number, and the

wiring connections.

Appendix A, Understanding the Ordering Code,explains the hardware and software

configuration of your particular controller.

MECHANICAL INSTALLATION

To install the controller

1. Prepare the control panel cut-out to the size shown in Figure 1-3, or 1-4.

2. Insert the controller through the panel cut-out.

3. Spring the upper and lower panel retaining clips into place. Secure the controller in

position by holding it level and pushing both retaining clips forward.

Note: If the panel retaining clips subsequently need removing, in order to extract the

controller from the control panel, they can be unhooked from the side with either your fingers,

or a screwdriver.

Unplugging and plugging-in the controller

If required, the controller can be unplugged from its sleeve by easing the latching ears

outwards and pulling it forward out of the sleeve. When plugging the controller back into its

sleeve, ensure that the latching ears click into place in order to secure the IP65 sealing.

NEW SLEEVE DESIGN MKIII

From Jan-03 an improved design of 1/8 DIN long sleeve is shipped with all new 2408

controllers and indicators. (The month and year of manufacture are shown in the last two

pairs of digits of the instrument serial number).

Details

A new sealing gasket will be fitted onto the instrument bezel !. This gasket replaces the

gasket which was moulded into the front of the sleeve of all previous instruments.

The gasket previously moulded into the sleeve where it fits behind the panel is now supplied

as a separate item ".

Reasons for the Change

This change is to ensure that IP65 sealing is reliably achieved and less physical effort is

required to insert the instrument into the new sleeve.

Recommendations

1. An instrument delivered after Jan 03 should be used with the sleeve supplied

2. If the instrument is required to replace one already in use, the existing sleeve should

also be replaced

3. A new instrument can be fitted into an existing sleeve by carefully removing gasket

!but IP65 sealing will not be maintained

4. An existing instrument can be fitted into a new sleeve but IP65 sealing will not be

maintained

It is, however, possible to achieve IP65 sealing for 3 and 4 above. A gasket kit is available by

quoting Part No SUB24/GAS2408.

Then:-

5. To fit a new instrument in an older sleeve carefully remove gasket !. Replace it

with the thinner (1.25mm) gasket from the kit

6. To fit an existing instrument into a new sleeve fit the thicker (1.6mm) gasket from

the kit between the instrument and the sleeve

The seal "supplied as a separate item with a new instrument, should be placed over the

sleeve prior to mounting it through the panel cut out as shown below:-

ELECTRICAL INSTALLATION

This section consists of five topics:

• Rear terminal layouts

• Fixed connections

• Plug-in module connections

• Typical wiring diagrams

• Motorised valve connections.

WARNING

You must ensure that the controller is correctly configured for your application.

Incorrect configuration could result in damage to the process being controlled, and/or

personal injury. It is your responsibility, as the installer, to ensure that the configuration

is correct. The controller may either have been configured when ordered, or may need

configuring now. See Chapter 6, Configuration.

408 and 2404 Controller

All electrical connections are made to the screw terminals at the rear of the controller. If you

wish to use crimp connectors, the correct size is AMP part number 349262-1. They accept

wire sizes from 0.5 to 1.5 mm2(16 to 22 AWG). The terminals are protected by a clear

plastic hinged cover to prevent hands, or metal, making accidental contact with live wires.

Rear terminal layouts

The rear terminal layouts are shown in Figures 1-5 and 1-6. The right-hand column carries

the connections to the power supply, digital inputs 1 and 2, alarm relay and sensor input. The

second and third columns from the right carry the connections to the plug-in modules. The

connections depend upon the type of module installed, if any. To determine which plug-in

modules are fitted, refer to the ordering code and wiring data on the controller side labels.

Sensor input connections

The connections for the various types of sensor input are shown below.

PLUG-IN MODULE CONNECTIONS

Module 1, 2 and 3

Module positions 1, 2 and 3 are plug-in modules. They can be either two terminal modules of

the types shown in Figure 1-7, or four terminal modules of the types shown in Table 1-1.

The tables show the connections to each module and the functions that they can perform.

Module 1 is normally used for heating and module 2 for cooling although the actual functions

will depend upon how the controller has been configured.

PDS modes

Table 1-8 refers to PDS modes 1 and 2.

PDS stands for ‘Pulse Density Signalling’ Input/Output. This is a proprietary technique for

bi-directional transmission of analogue and digital data over a simple 2-wire connection.

PDS 1 mode uses a logic output module to control aTE10S solid state relay and provides a

load failure alarm.

PDS 2 mode uses a logic output module to control a TE10S solid state relay, provide

load/SSR failure alarms, and read back the load current for display on the controller.
