Alarm Conditions and Corrective Action
This section lists all of the IPS-4 Analyzer system alarm messages (Condi-
tion/Alarm Name), describes what triggers the alarms, and provides action
that is required to reset the alarms (Description and Suggested Corrective
Action).
The system alarm relay contact opens on alarm. A system alarm can
result from any of the alarm conditions listed below. Some alarms may
not apply based on the system hardware configuration. For example,
systems without a heated sample system will not have a heater RTD
alarm.
Condition/Alarm Name Description and Suggested Corrective Action
Heater Temperature This alarm applies only to systems with a heated Oven/Sample System
Enclosure.
This alarm condition indicates the Oven Heater Plate temperature is
approaching its over-temperature limit; a soft shutdown of the heater
will occur. A soft shutdown means the system will shut down the heater
to ensure the temperature of the heater plate does not continue to
increase to ensure it will not exceed its temperature rating.
Corrective Action:
Take appropriate safety precautions, open the Electronics Enclosure
and the Oven/Sample System Enclosure doors, and:
• Using an Ohm Meter, measure the resistance of the Oven Heater
Plate RTD and test it for an open circuit. If the RTD is faulty, contact
AMETEK for assistance.
Cell Temperature
Bench Temperature
Oven Temperature Note:
The Cell and Over Temperature alarms apply only to systems with a
heated Oven/Sample System Enclosure.
These alarm conditions indicate that the specic temperature-controlled
zone (Cell, Bench, Oven) is operating below or above its set point value
by more than 5 °C (typical; set point may vary).
If one of these alarms is caused by low temperatures in any of the
temperature-controlled zones, the analyzer will automatically switch to
Not Ready mode to ensure the system does not become plugged due
to a low temperature in one of its zones.
This error can also be caused by a blown fuse, power interruption, or a
power spike, a failed heater, or wiring problems.
Corrective Action:
For alarms caused by Low / High Temperatures:
• From the User Interface Panel:
- Check current operating temperatures for each temperature zone
and compare them to their set point temperatures.
- Check each of the associated conguration parameters for
temperature control. These parameters may have been lost as a
result of a power interruption or a power spike.
