5.5 Configuration with DIP switches
A number of settings can be changed using DIP switches (see appendix A, position M).
Note: When changing settings with DIP switches in a parallel or split-phase/3-phase system one should be aware that not all settings
are relevant on all Multis. This because some settings will be dictated by the Master or Leader.
Some settings are only relevant in the Master/Leader (ie they are not relevant in a slave or in a follower). Other settings are not relevant
for slaves but are relevant for followers.
A note on used terminology:
A system in which more than one Multi is used to create a single AC phase is called a parallel system. In this case one of the Multis will
control the whole phase, this one is called the master. The others, called slaves, will just listen to the master to determine their action.
It is also possible to create more AC phases (split-phase or 3-phase) with 2 or 3 Multis. In this case the Multi in phase L1 is called the
Leader. The Multis in phase L2 (and L3 if available) will generate the same AC frequency but will follow L1 with a fixed phase shift.
These Multis are called followers.
If more Multis are used per phase in a split-phase or 3-phase system (for instance 6 Multis used to build a 3-phase system with 2 Multis
per phase) then the Leader of the system is also the Master of phase L1. The Followers in phase L2 and L3 will also take the Master
role in phase L2 and L3. All others will be slaves.
Setting up parallel or split-phase/3-phase systems should be done by software, see paragraph 5.3.
TIP: If you don't want to bother about a Multi being a master/slave/follower then the easiest and most straight forward way is to set
all settings identically on all Multis.
General procedure:
Turn the Multi on, preferably without load and without AC voltage on the input. The Multi will then operate in inverter mode.
Step 1: Set the DIP switches for:
- the required current limitation of the AC input
- AES (Automatic Economy Switch)
- limitation of the charging current
Press the 'Up' button for 2 seconds (upper button to the right of the DIP switches, see appendix A, position K) to store the settings after
the required values have been set. You can now re-use the DIP switches to apply the remaining settings (step 2).
Step 2: other settings, set the dipswitches for:
- Charge voltages
- Absorption time
- Adaptive charging
- Dynamic current limiter
- UPS function
- converter voltage
- converter frequency
Press the 'Down' button for 2 seconds (lower button to the right of the DIP switches) to store the settings after the dipswitches have
been set in the correct position. You can now leave the DIP switches in the selected positions, so that the 'other settings' can always be
recovered.
Remarks:
- The DIP switch functions are described in 'top to bottom' order. Since the uppermost DIP switch has the highest number (8),
descriptions start with the switch numbered 8.
For parallel or 3-phase mode, read the whole setting procedure and make a note of the required DIP switch settings before actually
implementing them.
Detailed instruction:
5.5.1 Step 1
5.5.1.1 Current limitation AC input (default: 50A)
If the current demand (Multi load + battery charger) threatens to exceed the set current, the MultiPlus will first reduce its charging
current (PowerControl), and subsequently supply additional power from the battery (PowerAssist), if needed.
The AC input current limit can be set to eight different values by means of DIP switches.
With a Multi Control Panel, a variable current limit can be set for the AC input.
