WARNING
Risk of explosion!
In explosion-hazard areas, electrostatic discharge may cause
a spark to ignite on the antenna.
► Do not clean antenna in explosion-hazard areas with a dry
cloth. Use a damp cloth for cleaning.
WARNING
Risk of explosion!
In explosion-hazard areas, electrostatic discharge may cause
a spark to ignite on the housing and sensing head.
► Do not clean housing and sensing head in explosion-
hazard areas with a dry cloth. Use a damp cloth for
cleaning.
WARNING
Risk of explosion!
Replacement of components may impair intrinsic safety.
12.1 Sensor change
The sensor can be replaced in a hazardous area without
interrupting the supply voltage. The sensor can be changed at
any time.
When replacing with a sensor of the same type (same order
number as the current sensor), the configuration settings are
retained. If a different sensor type (different order number) is
used, the configuration settings are overwritten with the
factory settings of the new sensor.
12.1.1 Features for changing the sensor
Features for changing the sensor are available in PolySoft.
Sensor lock feature
When activated, the use of other sensors (based on the order
number of the current sensor) is blocked.
Sensor change feature
This feature allows a sensor to be removed during operation
without an error being signaled. When activated, the
maintenance signal is output.
12.1.2 Changing the sensor
1. Activate the sensing head feature in PolySoft.
 Maintenance signal is issued.
2. Replace the old sensor with a new sensor:
a. Loosen the set screw (Fig. B 2).
b. Unscrew the bayonet ring (Fig. B 3).
c. Insert sensor (Fig. B 4) into opening.
Align Dräger logo with marking on housing (Fig. B 5).
 The successful loading of the sensor data is
confirmed in PolySoft.
d. Secure the sensor with the bayonet ring.
e. Tighten the set screw. Required for installation in
Zone 22.
3. If necessary, attach the tag supplied with the sensor to the
gas detector. The tag can be used to identify which type of
gas is being measured even in the event of a power
failure.
4. The sensor warm-up time is displayed in PolySoft.
 The maintenance signal persists until warm-up
phase 1 is completed. Maximum warm-up time of a
new sensor: see the instructions for use of the sensor.
For oxygen: approvals as per EN 50104.
5. Calibrate the gas detector after completion of warm-up
phase 2.
12.2 Bump test
A bump test is a quick test to check the sensitivity without
transmitting the measured value to the controller. The feature
is available in PolySoft.
12.3 Battery pack
12.3.1 Battery charge
The gas detector outputs three warning thresholds for the
battery charge during operation.

13 Settings

13.1 Sensor settings

Sensor settings are available in PolySoft.
– Setting the capture range
The capture range allows unwanted zero deviations to be
suppressed. The setting affects the measured value which
is output.
This feature is used to define the capture range and the
capture value limits.
– Resetting the sensor to the factory settings
The gas detector remains connected to the
™
ISA100 Wireless network and via Bluetooth
– Setting the calibration interval
The calibration interval defines the time window for the
next calibration. If the interval expires, the gas detector
issues a warning.
– Sensor self-test
