MS Code MStatus Alarm Type Condition / Description and Suggested Corrective Action
32 6 Warning w Lamp Control
One or both lamp pulse current-control signals has exceeded 9.5
VDC. The Lamp Maximum range is typically 4.5–7.8 VDC (may
vary, check EEPROM Data Sheets for actual value).
This alarm may occur during a cold start, but should clear after the
source lamps have stabilized.
Corrective Action:
Take appropriate safety precautions, open the Electronics Enclo-
sure, and:
• Ensure the lamp sockets are attached securely to the lamps and
that the Lamp Compression Bar is in place.
• Ensure the lamps are inserted completely into the Detector Assem-
bly.
• Check the at cable between the Optical Bench board (J103) and
the PMT Bu󰀨er for proper connections and inspect it for damage
(cuts, nicks, burn marks, etc.).
• Check the PMT high-voltage connections at the Optical Bench
board (J101, J102) for proper connections.
From the User Interface:
• The light levels may be too low as a result of natural aging of the
lamps. This is an indication that the lamps should be replaced as
soon as possible. As a temporary solution, initiate an Auto-Setup to
increase the PMT gain to compensate for the reduced light levels.
The Auto-Setup starts immediately upon pressing F1 •.
64 7 Fault f Oven Heater temp
The Oven Heater Plate temperature is approaching its over-tem-
perature limit of 177 °C (350 °F); a soft shutdown of the heater will
occur.
A soft shutdown of the heater will also occur when the Oven door
is open. A soft shutdown means the system will shut down the
heater to ensure the temperature of the heater plate does not con-
tinue to increase and exceed its temperature rating.
This alarm will occur during a cold start, but will clear after all tem-
perature zones have stabilized within their normal operating range.
Corrective Action:
Take appropriate safety precautions, open the Electronics Enclo-
sure, and:
• Using an Ohm Meter, measure the resistance of the Cell RTD
and test it for an open circuit. If the RTD is faulty, contact
AMETEK for assistance.
