5 Troubleshooting

5.1 Analyzer Repair

It is recommended that field repair of the ECA 450 be limited to:

• Simple checks of printed circuit board connectors

• Replacing the Probe Assembly

• Replacing the filter element in the Water Trap / Filter Assembly

• Replacing Sensors

All other repairs should be performed by an authorized Bacharach Service

Center. Any repairs performed by an unauthorized service organization will

void the analyzer’s warranty and release Bacharach, Inc. of any implied or

written product liability.

Before returning your analyzer for repair, you may be able to determine and

resolve a problem using the Troubleshooting Guide in Section 5.4.

5.2 Problem Messages Displayed After Warm-Up

If there were problems detected during warm-up, messages that describe the

nature of the problems are sequentially displayed at the bottom of the screen

immediately following the analyzer’s 60 second warm-up period.

Note that the analyzer will not automatically switch to the Combustion Test

HOLD screen if problems were detected. The analyzer, however, can still be

used to perform any test that does not depend on the sensor that is in error.

Press the RUN key to manually enter the Combustion Test HOLD screen to

continue using the analyzer.

The following is a list of the problem messages that may appear after warm-

up completes:

O2 Sensor Error – O

sensor is depleted, unplugged, or the sensor was

exposed to flue gas during warm-up.

TS Sensor Error – The probe’s flue gas thermocouple not connected to

analyzer, or the temperature being measured by this thermocouple is outside

the range of –4 to 212 °F (–20 to 100 °C).

TA Sensor Error – Primary air temperature as being measured by a

thermocouple connected to the T-AIR connector is outside the range of

–4 to 212 °F (–20 to 100 °C).

NO2 Sensor Error – NO

sensor was exposed to flue gas during warm-up.

HC Sensor Error – HC sensor is defective or unplugged.

NOXIDE Sensor Error – NO sensor was exposed to flue gas during warm-up.
