6-64 | Model 933 UV Analyzer
Alarm Type / Alarm Condition Description and Suggested Corrective Action
Warning Cell Temp The Measuring Cell temperature has exceeded its Too Hot setpoint or has
fallen below its Too Cold setpoint, or the Measuring Cell temperature range
is not set properly.
Corrective Action:
From the Temperature Control dialog box, check the Cell Too Hot and
Too Cold setpoints. Also, check the Cell temperature Range; it should be
set to Range “A” (-3 °C to 66 °C). See “Temperature Control” in Chapter 4.
Perform the following checks:
• Check the ambient temperature around the analyzer; if it is higher than
the Too Hot setpoint or lower than the Too Cold setpoint, adjust the
surrounding temperature to within the Cell temperature measuring Range.
Take appropriate safety precautions, open the Upper Enclosure, and:
• Check the jumpers at JP300 on the Micro-Interface board for proper
temperature range setting. The typical default jumper setting is Range “A”
(jumpers 1-2). See “Temperature Control” in Chapter 4.
• Check the Measuring Cell RTD (Upper Enclosure, see Figure 6-1) for a
short or an open circuit. Replace the RTD, if necessary. Contact AMETEK
to verify operation before removing this component.
• Replace the Micro-Interface board. Contact AMETEK to verify
operation before removing this board.
