ECA 450 Operation
Instruction 0024-9400

2 Operation
2.1 Turning On the Analyzer
Important! Prior to initially operating the analyzer, be sure to first charge the
battery per Section 4.1.
Before turning on the analyzer, connect the probe’s gas hose, pressure hose,
and thermocouple to the analyzer’s GAS, PRESSURE, and T-STACK
connectors, respectively (refer to Section 1.5.1).
Turn on the analyzer by pressing the I/O key. Observe that all display
segments are briefly turned on to verify their operation. The display then
shows the following information as the analyzer performs its 60 second
warm-up sequence:
BACHARACH, INC
ECA 450
WARM-UP xx
Where: xx = warm-up time, counting down from 60 seconds
Note: The software’s version number is briefly displayed at the bottom of the
screen prior to the start of the warm-up sequence.
At the end of a normal warm-up sequence, the message “No Problems
Detected” is briefly displayed followed by the display of the Combustion Test
HOLD screen. If, however, a problem was detected during warm-up, the
analyzer will display the message “Problem(s) Detected” and sequentially
display a list of those problems at the bottom of the screen, and then wait for
operator intervention. Refer to Section 5.2 Troubleshooting Guide for a list of
possible error messages and the recommended corrective action.
2.2 Turning Off the Analyzer
The analyzer is turned off by again pressing the I/O key. If there is any
residual gas inside the sensor chamber, the message “Purging Sensors” is
displayed while the analyzer purges itself with fresh air. The purging process
continues until all gas concentrations inside the analyzer have reached safe
levels.
Once the sensor chamber has been purged, the analyzer enters its normal 5-
second-delay period; after which the analyzer turns off.
Important! The probe must be removed from the stack during the purging
process to allow fresh air to be drawn through the sensor chamber.
Tips: Pressing the I/O key will abort the purging process. During the off-delay
period, the analyzer can be turned back on by pressing the RUN key.
