Fault Alarms; Off-Spec Alarms - Ametek 241CE II User Manual

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 flash 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.

Off-Spec Alarms

An Off-Spec – or out-of-specification – Alarm indicates that the current value
for the Off-Spec parameter is higher than a preset value. The Off-Spec Alarm
can be enabled from the Stat\History menu.
The Off-Spec Alarm currently is used only for HCDP. The HCDP Off-Spec Alarm
(HCDPA) indicates that the current HCDP temperature is above (greater than)
the HCDP temperature Off-Spec Alarm setpoint value (ApplicCFG : HCDPA).
When the Hydrocarbon Dewpoint Off-Spec Alarm (HCDPA) is triggered, LED 6
on the User Interface turns On, but only if the Off-Spec Alarm is enabled (Stat\
History : En\Dis Alrm?). If triggered, this alarm will be also be displayed on the
User Interface if the Off-Spec Alarm is enabled.
