Maintenance
Identify the sensor assembly needed via the A-5K-SENS code on the interior sensor label and
obtain the appropriate sensor assembly. Screw the replacement XCell sensor onto the Sensor
Body Assembly, ensuring that the XCell sensor mates flush against the bottom edge of the Sensor
Body Assembly.

Alarm set points, span value, full scale limit and alarm direction will not change when
replacing a sensor with the same gas and range. Alarm set points, span value, full scale
limit and alarm direction will change to the new sensor settings when replacing a sensor
with a different gas and/or range.
The TG5000 Gas Monitor is shipped with the Sensor Swap Delay enabled. This means that the
4-20 mA output signal and the fault relay will hold off a fault indication for two minutes before the
missing sensor indication is displayed on the device. This setting allows the operator to
exchange sensor modules without a fault indication. See Swap Delay in section 4.2.1 for more
details.
It is recommended that all other maintenance be performed at an MSA
factory-authorized service center.
