Table 32: Analyzer Fault / Warning Troubleshooting
Fault / Warning Troubleshooting Tips
Cell Temperature
•
Oven heater fuse is blown (ACTS:25)
• Cell assembly is not securely clamped to the heaters
•
Oven heater(s) inoperative
• Steam lines, sample probe nozzle, and analyzer flange are not sufficiently insulated
•
Set point for low temperature alarm is incorrect
NOTE: If this fault is active but the temperature is above the low temperature set point,
this indicates that the High Cell Temperature setpoint is set too low. This setpoint can
only be set through the web GUI. Refer to Section 5.3.1
High High Sulfur
•
The sulfur vapor concentration in the sample has risen to unacceptable levels. This
usually indicates that the probe’s condenser tip is not cool enough to condense
sulfur in the process pipe.
•
Probe cooler solenoid is not functioning
• Probe cooler instrument air flow rate is not high enough
• Check probe cooler air outlet on left side of analyzer for air flow
Measure Range
Reference Range
• UV lamp is nearing the end of its useful life and requires changing
• UV lamp is not operating
•
Fuse on UV power supply is blown (integral with the power switch on the bottom
side of the UV lamp supply enclosure inside the control cabinet)
• Fuse on ACTS28 is blown
•
Anti-Solarant solution transmissivity has degraded.
• Cell windows are dirty
•
Optical Fibres have become damaged
Dark Range
• Spectrometer problem, consult factory .
I/O Board
•
The I/O board is not communicating with the controller board.
• The spectrometer is not communicating with the controller board
• Check ArcNet wiring.
•
Check USB connection at spectrometer and at top of controller board
Cabinet
Temperature
• Cabinet cooler air solenoid not functioning
•
Air supply to Vortec cooler is turned off
• Analyzer is installed in direct sunshine and requires a sun shade .
High Absorbance
•
The H
2
S and or SO
2
concentration is out of range (process issue)
• The analyzer is not zeroed.
•
Switch analyzer to backpurge and ensure that the spectrum displayed on the
Absorbance panel goes to zero; if it does not, immediately perform a Manual Zero
High Integration
Period
• UV lamp is nearing the end of its useful life
•
UV lamp is not operating (only in conjunction with Measure / Reference range fault)
• Anti-Solarant solution transmissivity has degraded.
•
Cell windows are dirty
•
Optical fibres have been damaged
• ACTS 28 fuse or lamp power supply fuse blown (only in conjunction with Measure /
Reference range fault)
Low Reference
Peak
• UV lamp is nearing the end of its useful life
•
UV lamp is not operating (only in conjunction with Measure / Reference range fault)
• Anti-Solarant solution transmissivity has degraded.
• Cell windows are dirty
•
Optical fibres have been damaged
• ACTS 28 fuse or lamp power supply fuse blown (only in conjunction with Measure /
Reference range fault)
High Sulfur Vapor
• Sulfur vapour concentration approaching fault set point
• Confirm probe cooler is operating by checking for air flow from probe vent on left
side of analyzer cabinet.
