PERIPHERALS CONNECTION
Connecting boilers to the control unit
The cascade interface PCB is used to
connect the RVS control unit to the boilers.
One cascade interface PCB must be used
for every boiler of the cascade (e.g. 3 boilers
with 3 interfaces).
A. boiler connection via BridgeNet BUS
B. RVS63 connection via LPB
C. LED
D. LED
E. micro-switches
CAUTION!
Prior to performing the electrical
connections or allocating the code,
disconnect the power supply to the boiler
and control unit.
Observe the polarities when performing
the connections.
Boiler address allocation
Every boiler communicates with the control
unit through the cascade interface PCB.
In the cascade operation
(maximum 8
elements) it is necessary to allocate an
LPB (Siemens BUS) address to each boiler.
For the cascade to function properly,
a single address must be allocated to
each boiler through the corresponding
confi guration of the “E” micro-switches on
the interface.
Refer to the adjacent fi gure for setting the
addresses.
IMPORTANT:
The identifi
cation numbers must be
entered in succession, always starting
from boiler number 1.
Diagnostics
• LEDs C and D OFF
cascade interface not connected
• LED C ON
cascade interface powered
• LED D fl ashing
LPB communication present
• LED D OFF
LPB communication absent
Connecting the cascade interface PCB to
the boiler
The cascade interface PCB is housed in the
boiler's instrument compartment.
Each PCB is connected to its boiler through
the Bridgenet BUS connection.
All cascade interface PCBs are connected
in parallel to the RVS control unit through
LPB.
