Fault Alarms; Off-Spec Alarms - Ametek 241CE II Operator's Manual

Fault Alarms

Fault alarms indicate that a serious condition has been detected which
interferes with proper operation of the analyzer – a failure of an integral
part of the system has occurred. When a Fault alarm is present, the alpha-
numeric 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 (Ap-
plicCFG : 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.
