COMMISSIONING
For sensors that e.g. can be poisoned by silicones like all semiconductor and catalytic bead sensors, it is imperative to
remove the protective cap supplied only after all silicones are dry, and then energize the device.
The protective cap has to be used in subsequent cleaning work with water jet or steam, too, in order to protect the
sensor.
For fast and comfortable commissioning we recommend proceeding as follows. For digital devices with self-monitoring
all internal errors are visible via the LED. All other error sources often have their origins in the field, because it is here
where most of the causes for problems in the field bus communication appear.
Optical Check
Right cable type used.
Correct mounting height according to definition in Mounting.
Led status
Protective cap removed from the sensor.
Run-in period
In order to obtain an optimum fresh air setting, it is necessary to run the unit continuously at least for 48 hours without
shutdown under unpolluted ambient air conditions.
Selection Gas Type with Unit
The selection of the desired and connected gas sensor type is made by pre-set values.
If other gas sensor types are connected, you have to adjust them with the configuration tool, because otherwise the
device will respond with an error message.
Connection possible as digital sensor cartridge SC2.
The selection contains all necessary information for the controller and is also used for comparing the real, digital data
with the settings.
This feature increases the user and operating security.
There is an entry available per gas type for each unit; at the moment there are 100 selection options.
