5.5.1 AES (Automatic Economy Switch)
Procedure: set ds5 to the required value:
ds5
off = AES off
on = AES on
Note: The AES option is only effective if the unit is used ‘stand alone’.
5.5.2 Inverter voltage
Procedure: set ds4 to the required value:
ds4
off = 240V
on = 230V
5.5.3 Inverter frequency
Procedure: set ds3 to the required value:
ds3
off = 60Hz
on = 50Hz
5.5.4 Stand-alone, parallel and 3-phase operation
DIP switches ds2 and ds1 are reserved for the selection of stand-alone, parallel
or 3-phase operation
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 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 setting of DIP switches ds5 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, the ‘Inverter voltage setting’ is 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.
