If the gas detector can no longer be calibrated, the sensor
must be replaced!
Only use the DrägerSensor XXS with the same part
number!
1. Connect the gas detector to a PC using the communication
module.
2. In the CC-Vision Basic PC software
1)
, open the “Sensor
replacement assistant” feature and follow the instructions.
a. Switch off the gas detector.
b. Loosen the four screws on the rear part of the housing.
c. Open the front part of the housing.
d. Remove the battery (optional).
e. Remove the sensor.
f. Insert the new sensor and make a note of the sensor
code printed on the sensor.
g. If the battery was removed: Wait for 5 seconds, insert
new battery. The battery runtime is reset when the
battery is inserted.
h. Place the front part of the housing on the gas detector
and re-tighten the four screws on the rear part of the
housing.
3. Sign in the sensor with the previously recorded sensor
code.
4. After the sensor replacement, the sensor requires a warm-
up phase (see the sensor data sheet). The displayed
concentration flashes until the warm-up phase is complete.
5. After the sensor replacement and the warm-up phase, the
gas detector must be calibrated (see Section 5 on Page 8).
If the sensor code of the new sensor does not match that
of the previous sensor, the new sensor must be signed on
with the CC-Vision Basic PC software as described. Dräger
recommends signing on the sensor with the Dräger
CC-Vision Basic PC software, even if the sensor code is
identical to the previous one.

Replacing the battery
WARNING
Risk of explosion!
►
Only the lithium battery type LBT 01** (order no.
83 26 856) may be used.
►
Do not remove or replace batteries in potentially explosive
areas. Do no throw used batteries into fire or try to open
them by force. Dispose of batteries in accordance with the
national provisions.
The battery is part of the Ex approval.
1. Switch off the gas detector.
2. Loosen the four screws on the rear part of the housing.
3. Open the front part of the housing, remove battery and wait
for 5 s.
4. Insert the new battery. Make sure the battery plug is
inserted correctly (see figure). The battery runtime is reset
when the battery is inserted.
5. Place the front part of the housing on the gas detector and
re-tighten the four screws on the rear part of the housing
(torque: 35 Ncm).
6. Turn on the gas detector.
A successful battery replacement is confirmed with a
vibration (5 s) when the gas detector is turned on.
Notice 160 is displayed after the start sequence (see
Section 6 on Page 10).
7. Confirm the notice with the [OK] button.
8. After the battery replacement, the sensor requires a warm-
up phase (see the sensor data sheet). The displayed
concentration flashes until the warm-up phase is complete.
