with the GT3000 pointing down.

The sensor module on the GT3000 Gas Detector
can be hot swapped, i.e. replaced without
removing power or de-classifying the area. To
replace a GTX Transmitter connected to the UD10
with a new transmitter or a different detector type,
the area
must be de-classified.
noTe
Removing the sensor module with power applied
will result in a fault condition until a new sensor
module of the same type is installed. When
replacing an oxygen sensor, this action will also
result in an alarm condition as the decreasing
4-20 mA signal passes through the alarm range.
Inhibit response devices to prevent unwanted
actuation.
For complete information regarding sensor replacement
with the GT3000 Gas Detector, refer to the GT3000
instruction manual number 95-8616.
