Maintenance
The following maintenance instructions must be carefully read,
understood and followed to prevent flammable or combustible
atmospheres from igniting and to ensure that the intrinsic
safety of the gas detector is not impaired.
WARNING
Incorrect measurement!
►
A bump test and/or calibration must be performed each
time the gas detector is opened. This includes any battery
change as well as each sensor replacement in the gas
detector.
NOTICE
Damage to components!
The gas detector contains components at risk of charging.
Before opening the gas detector, make sure that the operator
is earthed in order to prevent damage to the gas detector. For
example, earthing may be ensured by an ESD workplace
(electro static discharge).
NOTICE
Damage to the gas detector!
When replacing the battery or the sensor, make sure that no
components are damaged or short-circuited.
►
Do not use sharp objects to remove the battery or the
sensor.
WARNING
Replacing components may impair the intrinsic safety of the
gas detector. The following maintenance instructions must be
carefully read, understood and followed to prevent flammable
or combustible atmospheres from igniting and to ensure that
the intrinsic safety of the gas detector is not impaired.
►
When replacing the battery or a sensor, do not damage or
short-circuit any components. Do not use any sharp
objects to remove the battery or the sensor.
WARNING
Incorrect measurement results!
If a battery or sensor replacement is carried out incorrectly, this
may cause incorrect measurements.
►
Carry out a bump test and/or calibration each time the gas
detector is opened.
7.1
Configuring the gas detector
The gas detector can be configured using the Dräger
CC-Vision Basic PC software. For further information, see the
Dräger CC-Vision Basic online help.
To configure the gas detector using the Dräger CC-Vision
Basic PC software:
1. Use the communication module (order no. 83 18 587) to
connect the gas detector to a PC or the Dräger X-dock
maintenance station.
2. The configuration can be carried out using the Dräger
CC-Vision Basic PC software. For further information, see
the Dräger CC-Vision Basic online help or the instructions
for use of the Dräger X-dock maintenance station.
7.2
Operating time alarm / end of the
operating time
An individual operating time can be configured using the
Dräger CC-Vision Basic PC software to, for example, set a
“calibration date”, an “inspection date”, a “switch-off date”, an
“operating time alarm” etc.
If an operating time is configured, a warning period starts
before the end of the installed operating time. After the gas
detector is turned on, the remaining operating time flashes
during this warning period, e.g. “30” / “d” ( in days).
This operating time alarm triggers at 10 % of the configured
operating time (maximum 30 days before the end of the
operating time).
7.3
Data logger
The gas detector is equipped with a data logger. The data
logger saves events and the average concentration which are
stored for the duration of a period of time which can be variably
configured using the Dräger Gas Vision PC software or the
Dräger CC-Vision Basic PC software. Depending on the
number of changing measured values, the data logger runs for
up to four weeks at an interval of one minute (configurable). If
the data logger memory is full, the data logger overwrites the
oldest data.
7.4
Replacing the sensor
WARNING
Risk of explosion! Do not replace the sensor in explosion-
hazard areas. Replacing components may impair the intrinsic
safety of the gas detector.
The following maintenance instructions must be carefully read,
understood and followed to prevent flammable or combustible
atmospheres from igniting and to ensure that the intrinsic
safety of the gas detector is not impaired.
►
When replacing the sensor, make sure that no
components are damaged or short-circuited. Do not use
sharp objects to remove the sensor.
