L. Programming Aux Contacts (AUX1, AUX2)
L.1.1 Principle
The Auxiliary unit can be basically programmed for any operating situation of
the unit which is indicated with a LED. The programming is possible for one or
more operating situations. If the contact is programmed for many situations, it is
activated as soon as the unit finds itself in any one of the programmed
situations.
L.1.2 Example
L.1.2.1 Auxiliary contact as generator starter
When in the programming of the Auxiliary Contact, the State of Charge (SOC)
LED`s (LED 8) can be used as a condition, then you must take note of the
following requirements.
If you have to start an emergency back-up supply with a battery having a certain
SOC, then two SOC levels must be programmed. The first (i.e. Battery 25% LED)
for the starting or activating the Auxiliary Contact and the second (i.e. Battery
100% LED ) for stopping or deactivating the Auxiliary Contact. By programming
in this way the Auxiliary Contact starts with the lowest set condition and stops
when it has reached the highest programmed condition through charging.
L.1.2.2 Auxiliary Contact as Twilight Switch (With solar charger option)
The Auxiliary Contact can also be used as a twilight switch , i.e. for
automatically operating exterior lighting. Solar modules connected to the unit
will measure the light intensity. If the unit is operating without solar modules
and a twilight-switching function is desired, you can connect small solar cells with
the nominal voltage of the unit to the SOLAR terminals for the purpose of
measuring the light intensity. To function as a twilight-switch the Auxiliary Contact
must be programmed so that the condition “SOLAR CHARGE” LED is active.
Programming must be carried out in steps and in accordance with the description
for the programming of the Auxiliary Contact.
L.1.3.3 Manual operating of Auxiliary Contact:
The Auxiliary Contact can be operated manually at any time by pressing the
“AUX” button. The “Multi-display show
( ) to indicate that the
Contact is manually operated. By pushing the “AUX CONTACT” button again ,the
Contact is deactivated. Multi-display show
( ). By pushing it a third time,
automatic functions are restored and Multi-display show ( ).
