Parameters
11 .15 Functions of contacts 80 to 97
Contacts 80 to 97 are floating contacts. They can be
parameterized for various signalling functions. The
contacts between the relevant terminals close depend-
ing on the set function.
11 .15 .1 Contact 80, 81/82 function
Parameter I050
Parameter I050 = 0: Off. The contact will not be closed.
It has no function
Parameter I050 = 1: ready signal. The contact is closed
if the BCU is ready (switched on) and there is no fault
signal.
Parameter I050 = 2: air signal. The air signal is activated
as soon as a connected air actuator has reached or ex-
ceeded its High position (max. position).
Parameter I050 = 3: purge signal. The contact is closed
while purging is active.
Parameter I050 = 4: cooling air valve. The contact is
closed if the cooling air valve is to be actuated.
Parameter I050 = 6: fault signal. The contact is closed if
a fault lock-out is active.
Parameter I050 = 7: Burner 1 operating signal. The con-
tact is closed if burner 1 is in operation.
