2.4.3 - SUPPLEMENTARY BOARD
The Modular Boiler Drive (MBD) in fig.
9, supplied for each boiler by Unical,
manages to check a two-burner group
(2 x 90 = 180 kW). For boilers with output
> 360 kW, 2 or 3 supplementary boards
AM-5 are assembled by the manufac-
turer, each of them managing to check
up to 2 burners. For example, a boiler
with 5 burners (450 kW) is equipped with
two supplementary boards AM-5.
The supplementary boards have two
small dip-switches, which shall be po-
sitioned according to the patterns here
below, regardless the number of sup-
plementary boards AM-5 fitted (such
operation is carried out at the manufac-
turer’s workshop and will also be done
on site in case of the replacement of a
faulty one).
X1 = CVI supply (ignition PCB)
X2 = CVI supply (ignition PCB)
X3 = 230 V electrical supply from mains
X7 = to MDB by flat cable
