You can set whether the activated burner is a master burner or a slave
burner.
 Master burners
Master burners have their own combustion air supply, which is con-
trolled and monitored directly. The following monitoring/control func-
tions are performed on master burners:
– The combustion air pressure is monitored. For this, the "AirP" input
must be linked to the device that monitors the required air amount
(generally an air pressure monitor).
– The combustion air blower is activated via the "BLOW" output.
– The compound controller can be activated and monitored. This is
necessary when an electronic compound controller is present (see
section below, entitled "Compound controller").
 Slave burners
Slave burners do not have their own combustion air supply. As a re-
sult, no monitoring takes place. This burner type is used for multi-
burners, for example, which are fitted with a central combustion air
supply and a monitoring function.
Please also note the following with the Slave burner type:
 The "AirP" input must be connected to a signal indicating the pres-
ence of a central combustion air supply that is functioning correctly.
There is no check to ensure that this input is at rest position when the
burner is switched off.
 The burner cannot be started (signal at the "Start" input) until it is
guaranteed that there is no flammable mixture within the combustion
chamber or associated areas or within the exhaust system.
WARNING!
Loss of safety function due to incorrect use of the Slave bur-
ner type
If the Slave burner type is used to avoid pre-purge and a com-
bustion air supply is not guaranteed, serious injury or death may
result, depending on the application.
Only use the slave burner type if the combustion air supply is
guaranteed elsewhere.
