5.5.1.4 Stand-alone, parallel and 3-phase operation
Using DIP switches ds2 and ds1, three system configurations can be selected.
NOTE:
When configuring a parallel or 3-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 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 system, a number of settings are 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.
