3.1 Burner cascade communication setup
In order for the system to work for cascade the communication busses
must be parallel linked together. The managing burner uses the AL-bus
connection on J6 1-8 for burner cascade. The depending burner must be
connected to the managing burner on the J8 AL-bus connection.
It is important that the power on the J8 AL-bus connection on all
depending burners is switched to the OFF position. Also all burners in the
cascade system must have a unique address selected.

3.2 Setting the burner address (Rev. 4.0.905.15250)
The managing burner of the cascade system is connected to the AL-bus
connection on J6 1-8. This connection also provides the power for the
communication bus. The depending burners are all parallel connected to
the managing burner communication bus.
Since the bus power is provided by the managing burner on J6 1-8,
switch S1 must be set in the OFF position on all controls.

The burner address can be set through an e2prom setting or the
Dip-Switch input available on the control. Which option is used can be
set with the Dip-switch conguration parameter on the Labvision PC
software. Each burner must be congured with its own unique address.
3.2.1 E2prom address selection through e2prom setting
When the Dip-switch conguration is set to disabled the burner address is
selected with an e2prom parameter. This setting can be changed using a
computer with LabVision PC software.

3.2.2 E2prom address selection through dip-switch input
When the Dip-switch conguration is set to Cascade burner address
the burner address is selected with the dip-switch input. The switches
are numbered 1 to 8. When an invalid dip-switch setting is selected the
burner address will be set to a standalone burner. When the Dip-switch
conguration is set to Cascade burner address the E2prom parameter is
not used.
