Table 7-1: Analyzer Fault Table
Cell Temperature
• Oven heater fuse is blown (ACTS:25)
• Cell assembly is not securely clamped to the heaters
•
Oven heater(s) is inoperative
•
Set-point for low temperature alarm is incorrect
High High Sulfur
•
The sulfur vapor concentration in the sample has risen
to unacceptable levels. This usually indicates that the
probe’s cold finger is too warm.
Measure Range
Reference Range
• UV lamp is nearing the end of its useful life (see
Section 7.3)
•
UV lamp is not operating (see Section 7.3)
• Anti-Solarant needs changing or has been changed
using expired solution
•
Cell windows are dirty
•
Optical Fiber defective
• UV lamp power supply is blown (ACTS:28)
Dark Range
• Spectrometer problem, consult factory .
I/O Board
• The I/O board is not communicating with the controller
board.
• Check ArcNet wiring.
Cabinet Temperature
•
RTD problem
• Computer temperature control is malfunctioning
•
Air supply to Vortec cooler is turned off.
High Absorbance
•
The H
2
S and or SO
2
concentration is out of range.
•
The analyzer is not zeroed.
High Integration Period
•
UV lamp is nearing the end of its useful life (see
Section 7.3)
• UV lamp is not operating (see Section 7.3)
•
Anti-Solarant needs changing or has been changed
using expired solution
• Cell windows are dirty
• Optical Fiber defective
•
UV lamp power supply is blown (ACTS:28)
Low Reference Peak
•
UV lamp is nearing the end of its useful life (see
Section 7.3)
• UV lamp is not operating (see Section 7.3)
• Anti-Solarant needs changing or has been changed
using expired solution
•
Cell windows are dirty
• Optical Fiber defective
• UV lamp power supply is blown (ACTS:28)
High Sulfur Vapor
•
The sulfur vapor concentration in the cell is
approaching the maximum value. The analyzer
readings are still valid.
