13.7.3 Dräger SensorAlive settings
This menu lets you select various parameters that define the
behavior of the Dräger SensorAlive:
● To activate or deactivate the LifeTest functions of the
sensor, select and confirm Settings > Sensor >
SensorAlive > DSA activation.
Select and confirm Enable or Disable.
● To acknowledge a clogged sensor, select Settings >
Sensor > SensorAlive > Ack faults.
● To enable or disable fault detection, select and confirm
Settings > Sensor > SensorAlive > Fault detection.
Select and confirm Enable or Disable.
The SensorAlive menu has the following sub-menus:
– LifeTest
– Sensitivity monitoring
36
Select Back to menu to exit
the function without changes
and confirm with [OK].
Select Confirm to accept the
settings and confirm with
[OK].
The following parameters can be set in the LifeTest sub-
menu:
● To define when to start a test run, select Time.
Enter a time and confirm. The test run is started when this
time is reached on the transmitter.
Transmitters do not support an automatic daylight
savings changeover.
● To define the value to be output via the transmitter during
the LifeTest, select Output behavior.
Select and confirm Fixed, Maintenance or Measurement
val..
● To define whether retests are to be carried out in a test run
if a LifeTest has a negative test result, select Repetition
mode.
Select and confirm Flexible.
If Static is selected, no retests are carried out and a new
test run is carried out at the indicated time instead.
● To define when to abort a LifeTest, select Cancel
threshold.
Enter a value and confirm.
During a LifeTest, test gas is applied to the Dräger
SensorAlive. This causes the measured value to rise. To
prevent an alarm from being triggered, the measured
value is not transmitted for a maximum of 15 minutes by
default. The behavior during a LifeTest can be configured
in the Output behavior menu, however. Independent of
this, the sensor detects a gas leak if the measured gas
concentration is greater than the gas concentration
expected as a result of the LifeTest. The difference
corresponds to the concentration of the gas leak and is
compared with the value entered in Cancel threshold. If
this value is exceeded, the LifeTest is immediately
aborted. The sensor switches back to measuring mode
and the transmitter once again outputs a measured value.
If relays are used, these are tripped on the transmitter
and, where applicable, an alarm is triggered.
The following parameters can be set in the Sensitiv. check
sub-menu:
● To define whether a warning needs to be issued, select
and confirm Activation.
● To define when a warning must be output, select and
confirm Alert < 50% or Alert < 40%.
