Warning
:
Back up Battery.
This instrument is fitted with a battery designed to retain configuration and other
settings in the event of a failure of the instrument power supply.
This battery has an expected life of 10 years minimum at a nominal ambient working
temperature (e.g. 25OC).
The battery life may be reduced if it is consistently operated in an elevated ambient
temperature environment.
Maintenance Schedule
A battery failure is only evident following a failure of the instrument power supply.
The battery should be replaced at regular intervals. Between 6 and 10 years is
recommended depending on usage and operating temperature. The battery is not user
serviceable, contact your local service centre to make suitable arrangements.
On older instruments contact your supplier to have the battery replaced prior to failure.
The age of the instrument is shown on the side label. This contains a serial number,
where the last four characters either show the week number and year of manufacture
WW YY, or a date in the format UK YYWW.
It is important to maintain a record of instrument configurations or use Eurotherm
iTools to make clone copies of fully working instruments. This is described in
section 27.13. Store this securely as a back up to be used to restore the
configuration.

1. Chapter 1 Installation and Operation
1.1 What Instrument Do I Have?
Thank you for choosing this Controller.
The 3508 controller is supplied in the standard 1/8 DIN size (48 x 96mm front panel). The 3504
controller is supplied in the standard ¼ DIN size (96 x 96mm front panel). They are intended for indoor
use only and for permanent installation in an electrical panel which encloses the rear housing, terminals
and wiring on the back. They are designed to control industrial and laboratory processes via input
sensors which measure the process variables and output actuators which adjust the process conditions.
1.1.1 Contents of Package
When unpacking your controller please check that the following items have been included.
1.1.1.1 3508 or 3504 Controller Mounted in its Sleeve
The 3504 contains up to six plug-in hardware modules; the 3508 has up to three. Additionally digital
communications modules can be fitted in two positions.
The modules provide an interface to a wide range of plant devices and those fitted are identified by an
ordering code printed on a label fixed to the side of the instrument. Check this against the description of
the code given in section 1.2 to ensure that you have the correct modules for your application. This
code also defines the basic functionality of the instrument which may be:-
•Controller only
•Programmer and controller
•Control type – Standard PID, valve positioner
•Digital communications type
•Options
1.1.1.2 Panel Retaining Clips
Two clips are required to secure the instrument sleeve in the panel. These are supplied fitted to the
sleeve.
1.1.1.3 Accessories Pack
For each input a 2.49Ωresistor is supplied for mA measurement. This will need to be fitted across the
respective input terminals
1.1.1.4 User Guide
Issue 6 of the guide applies to instrument software versions, V2.3+, and explains:-
•How to install the controller
•Physical wiring to the plant devices
•First switch on - ‘out of the box’.
•Principle of operation using the front panel buttons
•Introduction to configuration through iTools PC software
•Ethernet adaptor if Ethernet communications has been ordered

1.2 3504 and 3508 Ordering Code
The controller may have been ordered in accordance with the hardware code listed below. Alternatively,
it may have been ordered by quoting the ‘Quick Code’ listed in section 1.3. If ordered to the quick code
the controller will be configured in the factory. If it is not ordered using the quick code then it will be
necessary to configure the controller when it is first switched on. This is described in Chapter 2.

1.4 How to Install the Controller
This instrument is intended for permanent installation, for indoor use only, and to be enclosed in an
electrical panel.
Select a location where minimum vibrations are present and the ambient temperature is within 0 and
50oC (32 and 122oF).
The instrument can be mounted on a panel up to 15mm thick.
To assure IP65 and NEMA 12 front protection, use a panel with smooth surface texture.
Please read the safety information, at the end of this guide, before proceeding and refer to the EMC
Booklet part number HA025464 for further information. This and other relevant manuals may be
downloaded from www.eurotherm.co.uk.

1.4.2 To Install the Controller
1.4.2.1 Panel Cut-out
1. Prepare the panel cut-
out to the size shown in
the diagram
2. Insert the controller
through the cut-out.
3. Spring the panel
retaining clips into place.
Secure the controller in
position by holding it
level and pushing both
retaining clips forward.
4. Peel off the protective
cover from the display
Figure 1-2: Panel Cut out Dimensions
1.4.2.2 Recommended Minimum Spacing
The recommended
minimum spacing between
controllers shown here
should not be reduced to
allow sufficient natural air
flow
Figure 1-3: Minimum Spacing Between Controllers
1.4.3 Unplugging the Controller
The controller can be unplugged from its sleeve by easing the latching ears outwards and pulling it
forward out of the sleeve. When plugging it back into its sleeve, ensure that the latching ears click back
into place to maintain the IP65 sealing.

(1) Polarising keys are intended to prevent modules which are not supported in this controller from
being fitted into the controller. An example might be an unisolated module (coloured red) from a 2400
controller series. When pointing towards the top, as shown, the key prevents a controller, fitted with an
unsupported module, from being plugged into a sleeve which has been previously wired for isolated
modules. If an unisolated module is to be fitted, it is the users responsibility to ensure that it is safe to
install the controller in the particular application. When this has been verified the polarising key may be
adjusted with a screwdriver to point in the down direction.
(2) High or low voltage versions are orderable. Ensure you have the correct version
1.5.1 Wire Sizes
The screw terminals accept wire sizes from 0.5 to 1.5 mm (16 to 22AWG). Hinged covers prevent hands
or metal making accidental contact with live wires. The rear terminal screws should be tightened to
0.4Nm (3.5lb in).
