5.5.1 Step 1
5.5.1.2 Current limitation AC inputs (default: AC-in-1: 30A, AC-in-2: 16A)
If the current demand (Quattro load + battery charger) threatens to exceed the set current, the Quattro will first reduce its
charging current (PowerControl), and subsequently supply additional power from the battery (PowerAssist), if needed.
The AC-in-1 current limit (the generator) can be set to eight different values by means of DIP switches.
The AC-in-2 current limit can be set to two different values by means of DIP switches. With a Multi Control Panel, a variable
current limit can be set for the AC-in-2 input.
Procedure
AC-in-1 can be set using DIP switches ds8, ds7 and ds6 (default setting: 30A).
Procedure: set the DIP switches to the required value:
ds8 ds7 ds6
off off off = 6A (1.4kVA at 230V)
off off on = 10A (2.3kVA at 230V)
off on off = 12A (2.8kVA at 230V)
off on on = 16A (3.7kVA at 230V)
on off off = 20A (4.6kVA at 230V)
on off on = 25A (5,7kVA at 230V)
on on off = 30A (6,9kVA at 230V)
on on on = not used
Remark: Manufacturer-specified continuous power ratings for small generators are sometimes inclined to be rather
optimistic. In that case, the current limit should be set to a much lower value than would otherwise be
required on the basis of manufacturer-specified data.
AC-in-2 can be set in two steps using DIP switch ds5 (default setting: 16A).
Procedure: set ds5 to the required value:
ds5
off = 16A
on = 30A
5.5.1.3 Charging current limitation (default setting 75%)
For maximum battery life, a charge current of 10% to 20% of the capacity in Ah should be applied.
Example: optimal charge current of a 24V/500Ah battery bank: 50A to 100A.
The temperature sensor supplied automatically adjusts the charging voltage to the battery temperature.
If faster charging – and a subsequent higher current – is required:
- the temperature sensor supplied should be fitted to the battery, since fast charging can lead to a considerable temperature
rise of the battery bank. The charging voltage is adapted to the higher temperature (i.e. lowered) by means of the temperature
sensor.
- the bulk charging time will sometimes be so short that a fixed absorption time would be more satisfactory ('fixed' absorption
time, see ds5, step 2).
Procedure
The battery charging current can be set in four steps, using DIP switches ds4 and ds3 (default setting: 75%).
ds4 ds3
off off = 25%
off on = 50%
on off = 75%
on on = 100%
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.
