Ametek 241CE II User Manual

6-34 | Model 241CE II Hydrocarbon Dewpoint Analyzer
Alarm LED Status
The LEDs on the User Interface are numbered 1–7, from left to right. A lit
LED indicates that the condition associated with the LED currently exists.
Four of the seven LEDs indicate the status of corresponding alarms set
by four alarm relay contacts (two LEDs and their associated alarm relay
contacts are not currently used). The alarm setpoint values for the HCDP
temperature are preset at the factory, but can be changed in the field.
The conditions which define the Warning and Fault alarms are part of the
built-in, continuous diagnostics function. The HCDP temperature alarms
will be set at the end of the Cooling Stage, if the conditions that trigger
the alarm are present. The remaining alarms are set at the end of the stage
where the problem occurred.
The LEDs and their corresponding conditions when turned On are:
