5.5.1.4 Stand-alone, parallel, 3-phase and split phase operation
Using DIP switches ds2 and ds1, three system configurations can be selected.
NOTE:
- When configuring a parallel, 3-phase or split phase system, all related devices
should be interconnected using RJ45 UTP cables (see appendix C, D). All devices
must be turned on. They will subsequently return an error code (see Section 7),
since they have been integrated into a system and still are configured as 'stand-
alone'. This error message can safely be ignored.
- Storing settings (by pressing the 'Up' button (step 1) – and later on the 'Down'
button (step 2) – for 2 seconds) should be done on one device only. This device is
the 'master' in a parallel system or the 'leader' (L1) in a 3-phase or split phase
system.
In a parallel system, the step-1 setting of DIP switches ds8 to ds3 need to be done on
the master only. The slaves will follow the master with regard to these settings (hence
the master/slave relationship).
In a 3-phase or split phase system, a number of settings are also required for the
other devices, i.e. the followers (for phases L2 and L3).
(The followers, therefore, do not follow the leader for all settings, hence the
leader/follower terminology).
- A change in the setting 'stand-alone / parallel / 3-phase' is only activated after the
setting has been stored (by pressing the 'UP' button for 2 seconds) and after all
devices have been turned off and then on again. In order to start up a VE.Bus system
correctly, all devices should therefore be turned off after the settings have been
stored. They can then be turned on in any order. The system will not start until all
devices have been turned on.
- Note that only identical devices can be integrated in one system. Any attempt to use
different models in one system will fail. Such devices may possibly function correctly
again only after individual reconfiguration for 'stand-alone' operation.
The combination ds2=on and ds1=on is not used.
