Maintenance
When the cleaning process is complete, be sure to remove all objects from the light
path. It is recommended to check the sensor’s response to zero and calibration gas after
cleaning.
Using other cleaning solutions or not thoroughly removing the isopropyl alcohol with a
damp cloth may result in a gas reading from the hydrocarbon bonds of the solvent.
WARNING!
Do not place foreign objects in the sensor's analytical region (except for the “ULTIMA XIR PLUS
Cleaning Procedure” as described above); otherwise, the infrared beam can be partially blocked,
causing the sensor to generate false readings. All objects must be removed from the sensor's
analytical region for it to function properly.
Failure to follow the above warning can result in serious personal injury or loss of life.
6.2 Replacing an XCell Sensor
The only routine maintenance item is the sensor, which has a limited lifetime. The TG5000 sensors
with TruCal technology will indicate when the sensor is near end of life through the Status Menu.
When the Sensor Life & Health status is "Fair", you have approximately 2 months to replace the
sensor before it will no longer function. When a TruCal sensor is no longer capable of sensing it
will go into fault and LEDs will flash yellow. It is good practice to obtain a replacement sensing
element before the sensing element within your unit becomes inoperative.
There is no need to open the main enclosure. Simply unscrew the digital sensor assembly from
the Sensor Body Assembly.
WARNING!

Do not disassemble the sensor assembly. The sensing element inside may contain hazardous
material.

Handle the sensor carefully; the electrochemical version is a sealed unit which contains a
corrosive electrolyte.

Any leaked electrolyte that comes in contact with skin, eyes or clothes can cause burns.

If any contact with the electrolyte does occur, immediately rinse with a large quantity of water.
On contact with the eyes, rinse thoroughly with water for 15 minutes and consult a doctor.

Do not install a leaking sensor in the sensing head assembly. The leaking sensor must be
disposed of in accordance with local, state and federal laws.

As part of the product certification, it was verified that optional communication functions of this
gas detection instrument while operating at the maximum transaction rate do not adversely
affect the gas detection operation and functions of the instrument. The product certification,
however, does not include or imply approval of the SafeSwap feature, communications
protocol or functions provided by the software of this instrument or of the communications
apparatus and software connected to this instrument.

Follow the warnings below when removing or replacing sensors.
- Never remove or replace a Sensor Body Assembly or an Ultima XIR Plus while under power
or when explosive hazards are present.
- Confirm that the area is free of explosive hazards before removing or replacing an XCell
Sensor under power.
- To remove an XCell Sensor, unscrew XCell Sensor three full turns, wait 10 seconds, and then
remove the XCell Sensor completely.
Failure to follow the above warnings can result in serious personal injury or loss of life.
