8.4 Commonly Observed Problems

Table 8-2 is a list of commonly observed problems that may be encountered during normal

operation and servicing of the analyzer

Table 8-3: Troubleshooting Guide

Problem

Cause

Solution

1. Sensor Comm. Alarm

I.S. barrier channel blown.

Check DC voltage (Red & Black wires)

at bottom of Sensor block to be 10.5

volts for a Div1 unit and 24volts for a

Div 2 unit

Sensor block connector

unplugged or loose

2. Sensor Calibration Alarm Sensing tape is not installed.

Install sensing tape between sample

chamber and compression head.

Sample chamber is dirty.

Clean sample chamber.

Gas is running during the initial

start-up calibration

Perform Sensor Calibration on

unstained tape:

3. Tape movement Alarm

Tape is not installed over tape

counter capstan or tape is broken.

Check that Tape is path runs over the

tape counter capstan and is not broken

Tape capstan movement is

inhibited

Loosen set screw and move away from

plate.

IS barrier channel is blown

Check DC voltage (Red & Black wires)

at top of Sensor block to be 5 volts

4. Stain is not well defined

causing erratic readings.

Compression head not correctly

sealing.

Check the seal on the compression

head

Tape not seated properly

Remove tape and reinstall tape

5. Stain is uneven (darker at

top or bottom) causing erratic

readings.

Compression head not seated

properly.

Loosen screws that hold compression

head to chassis. Adjust compression

head so that it will sit flush against

sample chamber and check seal)

6. Stain is normal but

readings are still erratic.

Stains have too much overlap

Increase Tape Advance In Pulses

value in the Tape Box on the Global

tab of the GUI by 5 so that the stains

are further apart.

Back pressure on analyzer vent.

Check eductor for proper operation.

Frozen vent lines due to high

humidity in area.

Make sure vent slopes downward.

Sensor Current is too high. This

should be accompanied by a

Sensor Current alarm.

Lint in sample chamber causing light

blockage. Clean the sample chamber.

7. Stains overlapping each

other.

Insufficient pulses per tape

advance to allow correct stain

spacing.

Increase Tape Advance In Pulses

value in the Tape Box on the Global

tab of the application program by 5 so

that the stains are further apart.
