MasterBus specific alarms for multi Mass Sine
Ultra systems
Value
Meaning
Sync error
Synchronization error. The Mass Sine Ultra
switched to standby, there is no output.
Config error
Configuration error. This alarm is triggered
when more Mass Sine Ultra’s are needed for
a cluster than available in the system.
Install error
Error in the system installation, for instance
an expected slave is not in the Sync
network.
If one Mass Sine Ultra is in alarm, it switches Off together
with the other Mass Sine Ultra’s in the same cluster. This
applies for parallel, split phase and 3-phase configurations.

DIP switch settings for two Mass Sine Ultra’s in
parallel
The DIP switches have a combined function for parallel
settings of two Mass Sine Ultra’s. See table below and
section 6.1. MasterBus configuration is necessary for more
Mass Sine Ultra’s in a parallel connection.
By operating the DIP switches you will lose all
previous cluster configuration!

Operation of multiple Mass Sine Ultra systems
If connected in a more phase or parallel configuration, it is
important which Mass Sine Ultra you selected as the master
and which as the slave(s). Operation is done via the main
switch on the master. The slave Mass Sine Ultra’s must be
switched On already but they follow the master. If the master
is switched On or Off, the slaves follow. If there is more than
one master, for instance in a three phase by two parallel
configuration (3X2), operation is done on the L1 master.
