Fault Alarms
Fault alarms indicate that a serious condition has been detected which inter-
feres with proper operation of the analyzer – a failure of an integral part of the
system has occurred. When a Fault alarm is present, the alphanumeric display
will ash and LED 2 turns On to alert the operator that immediate attention is
required (the analyzer requires service).
Because any results obtained under a Fault alarm condition are invalid, the
operation of the analyzer is suspended and the analyzer is placed into Standby
Mode.
O-Spec Alarms
An O-Spec – or out-of-specication – Alarm indicates that the current value
for the O-Spec parameter is higher than a preset value. The O-Spec Alarm
can be enabled from the Stat\History menu.
The O-Spec Alarm currently is used only for HCDP. The HCDP O-Spec Alarm
(HCDPA) indicates that the current HCDP temperature is above (greater than)
the HCDP temperature O-Spec Alarm setpoint value (ApplicCFG : HCDPA).
When the Hydrocarbon Dewpoint O-Spec Alarm (HCDPA) is triggered, LED 6
on the User Interface turns On, but only if the O-Spec Alarm is enabled (Stat\
History : En\Dis Alrm?). If triggered, this alarm will be also be displayed on the
User Interface if the O-Spec Alarm is enabled.
