12.1.1 Alarm Relay Output
Alarms can operate a specific output (usually a relay). Any
individual alarm can operate an individual output or any
combination of alarms, up to four, can operate an individual
output. They are either supplied pre-configured* in
accordance with the ordering code or set up in configuration
level
.
* When supplied pre-configured, the default is:
IO1 is always Heat
OP2 is always AL2
OP3 is always Heat 4-20 mA
OP4 (AA) is always AL4
12.1.2 Alarm Indication
• ALM beacon flashing red = a new alarm
(unacknowledged)
• This is accompanied by a scrolling alarm message. A
typical default message will show the source of the
alarm followed by the type of alarm. For example,
‘ALARM 1 FULL SCALE HIGH’
• If more than one alarm is present further messages are
flashed in turn in the main display. The alarm
indication will continue while the alarm condition is
present and is not acknowledged.
• ALM beacon on continuously = alarm has been
acknowledged
12.1.3 To Acknowledge An Alarm
Press  and together.
The action, which now takes place, will depend on the type
of latching, which has been configured
Non-Latched Alarms
Alarm condition present when the alarm is acknowledged.
• ALM beacon on continuously.
• The alarm message(s) will continue to scroll
This state will continue for as long as the alarm condition
remains. When the alarm condition disappears all indication
also disappears.
If a relay has been attached to the alarm output, it will de-
energise when the alarm condition occurs and remain in this
condition until acknowledged or the alarm is no longer
present.
If the alarm condition disappears before it is acknowledged
the alarm resets immediately.
