Indicator and Alarm Unit
1Installing and Operating Instructions
Thank you for choosing the 2408 i panel mounted indicator. It will provide accurate measurement and display of
temperature and other process variables. A modular build accepts a wide range of plug-in modules allowing: up
to four alarm outputs, two process variable (PV) inputs, direct strain gauge/pressure sensor measurements,
custom linearisation, analogue retransmission, remote setpoint (SP) input and digital communications.
The indicator is supplied configured in accordance with the order code. The order code and instrument serial
number is shown on a label fixed to the top of the case, and this can be checked against the order code given in
section 5 of these instructions.
1.1 Contents of package
1. A peel-off label set - a convenient position is to fix a label
to the top right of the display.
2. A 2.49Ωresistor used as the load resistor for a mA input
3. Two panel retaining clips
4. Panel sealing gasket
1.2 Dimensions and Installation
1.2.1 To Install the Indicator
Please read the safety information in section 6 before proceeding.
The indicator is intended to be mounted on a panel within an enclosure such as a control cubicle.
1. Prepare the panel cut-out to the size shown.
2. Fit the sealing gasket behind the front bezel of the instrument.
3. Insert the indicator in its sleeve through the cut-out.
4. Spring the panel retaining clips into place. Secure the indicator in position by holding it level and pushing
both retaining clips forward.
5. Peel off the plastic film protecting the front of the indicator.
1.2.2 Removing The Indicator From The Sleeve
WThe indicator can be removed from its sleeve by easing the latching ears outwards and pulling it forward out
of the sleeve. When plugging the indicator back into its sleeve, ensure that the latching ears click into
place to maintain the moisture sealing protection.
It is recommended that power to the controller is turned off when removing or replacing the controller into
its sleeve, to prevent premature wear on the connectors when current is flowing through them.

1.3 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).
1.3.1 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
.
1.3.2 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.
1.3.3 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 from Eurotherm 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:-

2.2 Alarms
Alarms are used to alert an operator when a pre-set level has been exceeded. They are normally used to switch
an output (see section 2.2.2.) – usually a relay – to provide external actions to the process.
Soft Alarms are indication only and do not operate an output.
Events are generally defined as conditions, which occur as part of the operation of the plant. They do not require
operator intervention and, therefore, do not cause an alarm message to be displayed. They can be attached to
operate an output (relay) in the same way as an alarm.
2.2.1 Types of Alarm Used In The 2408i
This section shows graphically the operation of different types of alarm used in the indicator. The graphs show
changes in PV plotted against time. The PV may be derived from input 1, input 2 or the main PV which is derived
from input 1 & 2.

Rate of Change
On
Rate of change alarms detect if the rate of change in PV,
set as units per minute or per second, exceeds the
setpoint value. An alarm setpoint set + will detect
positive rates of change. An alarm setpoint set - will
detect negative rates of change. Therefore, if it is
required to measure the rate of change in both
directions then two alarms must be configured. Since
rate of change alarms are calculated over a period of
time a small delay may be apparent before the alarm is
indicated. This is generally only noticeable if the PV
changes very quickly.
Deviation Alarms. The setpoint used for deviation
alarms is normally derived as a remote input from
another device - for example, a temperature
controller. The setpoint can also be internally set
within the controller - in this case called the local
setpoint value.
Delay a settable time between an alarm occurring and
it being displayed on the indicator
Hysteresis is the difference between the point at which
the alarm switches ON and the point at which it switches
OFF.
It is used to prevent relay chatter.
Latching Alarms see 2.2.6
Blocking Alarms only occur after the start up phase
when the alarm has first entered a safe state. The
alarm is only indicated the next time it is active. It is
used, for example, to ignore start up conditions which
are not representative of running conditions.
2.2.2 Alarm Relay Output
Alarms can operate a specific relay or logic
output. Any individual alarm can operate an
individual output or any combination of alarms
can operate an individual output. They are
either supplied pre-configured in accordance
with the ordering code or set up in configuration
level.

2.2.3 Alarm Indication
An alarm occurs when the process conditions exceed a pre-set level (setpoint). It will be displayed on the
indicator as follows:-
1. The relevant alarm beacon will begin to flash
2. A four character alarm message will be shown as a double repeating flash in the main display. This message
specifies the alarm number (first character) and the type of alarm that has occurred (next three characters).
The message is flashed in addition to the ‘front’ displayed value
If more than one alarm is present the relevant beacon illuminates and further messages are flashed in the main
display. The alarm indication will continue while the alarm condition is present and is not acknowledged.

2.2.6 To Acknowledge An Alarm
An alarm can be acknowledged in two ways:-
1. Press the ACK/RESET button. (If this does not work it may have been disabled when the indicator was
configured).
2. Press and together.
The action, which now takes place, will depend on the type of latching, which has been configured
Non Latched Alarms
If the indicator has been configured for non-latching alarms the following action occurs:-
Alarm condition present when the alarm is acknowledged, will be indicated by a single repeating flash of the
alarm message and the beacon will continuously illuminate. This state will continue for as long as the alarm
condition remains. When the alarm condition disappears the indication will also disappear.
If a relay has been attached to the alarm output, it will operate when the alarm condition occurs and remain in the
operated condition until the alarm is acknowledged AND it is no longer present.
If the alarm condition disappears before it is acknowledged the alarm indication disappears as soon as the
condition disappears.
Latched Alarms
The indicator may have been configured for Automatic or Manual reset. The action which occurs when the
acknowledge button is pressed is described below:-
Automatic.
The alarm continues to be active until both the alarm condition is removed AND the alarm is acknowledged. The
acknowledgement can occur BEFORE the alarm condition is removed.
Manual
The alarm continues to be active until both the alarm condition is removed AND the alarm is acknowledged. The
acknowledgement can only occur AFTER the alarm condition is removed.
2.2.7 Alarm Inhibit
If a digital input has been configured for alarm inhibit, then all process alarm indication will be prevented for as
long as the input is ON. When the input is turned to OFF any alarms which are active will be displayed. If a delay
has been set on the alarm, the delay period will start from the time when the input is turned OFF. If the alarm has
been configured as latching the latching action is also inhibited whenever the input is ON. See section 4.5.4 and
4.5.6.
