Installation and operating instruction
Combustion manager W-FM 100 und W-FM 200
Bus connection / supply voltage
The CAN Bus line must not exceed a total length of 100 m. A second source trans-
former is required from a line length of 20 m between the combustion manager and
the last actuator, e. g. if the combustion manager is fitted to control panel. In this
case transformer 1 feeds the combustion manager and ABE, transformer 2 feeds
the actuators. In so doing, the power supply of the CAN bus line (AC1 and AC2)
between combustion manager and the first actuator must not be connected.
The ends of the bus line must be terminated with a bus termination resistor. The
bus termination is permanently installed in the ABE. On the last actuator or at the
O module, the bus termination must be set via a jumper. Bus termination must be
2
deactivated for all other participants.
The screen of the bus line must be terminated at both ends.
