The back display is not selectable in this mode

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 1.10) –
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.
Full Scale Low On On
Deviation Low On On
Deviation High On
Deviation Band On On On
Full Scale High On
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 section 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.

2.2.3 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 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 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.

2.2.8 To Change The Alarm Setpoints (trip levels)
Parameters are grouped in ‘lists’ according to their function. Each list has a heading.
The button steps through the parameter list headings (see section 2.4.1.)
