3 For Your Safety
3.5 Commissioning Notes
• Check all safety functions during commissioning!
• There is no feature to prevent RASTx connector plugs being transposed. Therefore en-
sure the correct assignment of the plant's plugs prior to commissioning.
• Check electromagnetic emissions specific to the application.
• While installing and commissioning the plant, the person in charge of the plant/heating
technician needs to document the following:
–
Parameter set values
– Setting values (e.g. curve progressions)
– Values describing the fuel/air ratio control.
This data can be printed using LSB remote software or alternatively being kept as a hand-
written note.
Retain this documentation and have it checked by the ’authority on the subject’.
WARNING!
For BT300 parameter settings which deviate from the application standards can be carried out
in access level 2. For this reason, check whether the parameter settings are consistent with
the corresponding application standards (e.g. EN 298, EN 230, EN 676, EN 267, etc.) or the
respective plant has to be approved separately.
WARNING!
While unlocking the safety interlock chain in the mode ’BURNER OFF’ BT300 does not lock
the system. BT300 prevents a burner start-up until safety interlock chains are locked.

In case your application needs an interlock of the plant while unlocking the safety interlock
chain also in ’BURNER OFF’ mode you must take suitable measures at the plant.
NOTICE
Should the safety times be changed, these changes must be documented on the devices

Bring an additional sticker for the device.

Note the changed safety times on this sticker.

The details on this sticker must be clear for reading and non-smudge.
3.5.1 Fuel/Air Ratio Control
• Guarantee proper operation by ensuring adequate excess air.
In order to do this, set the values for fuel and combustion air in such a way that
–
combustion chamber pressure
– fuel pressure
– temperature and pressure of the combustion air
can ensure proper, stable operation through the entire range of burner firing rate until next
periodic inspection.
• Pay attention to wear and tear of actuators and actuator elements.
• Measure characteristic values of combustion process to document proper operation.
