94 DF-310E Troubleshooting and Calibration
NOTE
If the analyzer is used in a portable mode, the optional isolation
valves should be used during transport to preserve the stability of
the zero calibration.
9.2.2 Storage Conditions
The Oxygen sensor was drained of electrolyte and thoroughly rinsed prior to shipment. Residual
fluid will maintain in the electrode systems for several weeks during transportation and
installation. If it is intended to store the system or delay installation and start-up for two months
or more it is recommended that the sensor be filled to the bottom of the reservoir with
Hummingbird
Replenishment Solution (RSA), which is provided as part of the Start-up and
Maintenance Kit . Remember to securely replace the cap when done. For extended storage, six
months or more, additional fluid should be added to allow for normal evaporation. At time of
start-up it is recommended that any remaining
Replenishment Solution be drained prior to
addition of the fresh electrolyte. Be sure that the storage location temperature does not exceed
50° C (122° F). Storage in direct sunlight can cause temperatures to exceed the recommended
limits even though ambient temperatures may be below the maximum temperature.
9.2.3 Sensor Maintenance
The analyzer does not require routine maintenance other than adding Replenishment Solution to
the electrolyte. Exposure to dry gas for an extended time gradually extracts water from the
sensor. The electrolyte needs to be refilled occasionally with Hummingbird Replenishment
Solution for optimum performance and long term reliability.
CAUTION
If the electrolyte level is low, only Hummingbird Replenishment
Solution should be added to the sensor for optimum performance
and long term reliability. Be sure to cap the bottle immediately after
use. In an emergency, distilled water can be used as an alternative,
however this is not recommend over an extended period.
Do not
add electrolyte solution to restore the electrolyte level. Do not
overfill.
The Sensor Assembly consists of two connected chambers. The operation of the sensor is
satisfactory as long as the level of electrolyte is above the minimum indicator line and below the
maximum line on the reservoir label.
One bottle of electrolyte, contains 100cc and the entire contents of the bottle should be added at
the time of startup. This quantity is sufficient for satisfactory operation. It is not necessary to
add additional electrolyte.
Typically, bone dry sample gas can extract approximately 5 to 10 cc of water per month. The
electrolyte level should be checked every 1 to 2 months. If the liquid level is low, add
Hummingbird Replenishment Solution to bring the electrolyte level between the minimum and
maximum indicator lines on the reservoir label. Operation at elevated temperatures and/or with
sample gases at very low dew points will increase the frequency of replenishing the electrolyte.
The Oxygen Analyzer is equipped with an Electrolyte Condition alarm to indicate that the
