5.4.3 Examples
5.4.3.1 Auxiliary Contact as generator starter
As per the battery capacity
When in the programming of the Auxiliary Contact, the Battery Capacity (LED 15-18) is 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 residual capacity,
then two battery levels must be programmed. The first (i.e. Battery 25% LED 17) for the starting or
activating the Auxiliary Contact and the second (i.e. Battery 100% LED15) for stopping or
deactivating the Auxiliary Contact. By programming like this the Auxiliary Contact works with the
lowest set condition and stops when it has reached the highest programmed condition through
charging.
As per the inverter output power (not available with some special executions)
Activating the auxiliary contact for the generator start can be programmed also on a pre-
determined output power of the inverter. The auxiliary contact will be activated if the inverter output
power exceeds 80% of the inverter nominal power during 3 minutes and/or 100% during 30
seconds.
The auxiliary contact will remain activated 30 minutes after the input current has come back to a
value lower than the one adjusted by the “INPUT LIMIT” (chap. 4.6.3). In other words, the contact
will be deactivated 30 minutes after the lighting out of the LED 200%.
This programming is achieved accordingly to chap. 5.4.2 of the user manual and by activating the
contact on LED 100% of “Power Monitor” (25).
5.4.3.2 Auxiliary Contact as Twilight Switch (with solar charger option)
The Auxiliary Contact of the COMPACT can also be used as a twilight switch, i.e. to operate
automatically the exterior lighting. With it the connected solar modules measure the light intensity.
If the COMPACT is operating without solar modules and a twilight-switching function is desired,
you can connect small solar cells with the nominal voltage of the COMPACT on 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 3) is active.
Programming must be carried out in steps and in accordance with the description for the
programming of the Auxiliary Contact.
5.4.4 Manual operating of Auxiliary Contact
The Auxiliary Contact can be operated at any time with the Push Button 21 (AUX. CONTACT). The
LED 6 „Contact manual“ lights up as information that the Contact is manually operated, and LED 5
„Contact active“ lights up when the Contact is active. By pushing the Push Button 21 a second
time, the Contact is deactivated. By pushing it the third time, automatic functions are restored.
5.5 Disabling some of the Compact functions
Each different function charger, inverter and transfer can be disabled. This is useful for specific
applications which are required to disable some of these three functions.
If you press the button (20) more than 2 seconds, you can have the access to the different
possibilities shown in the following diagram.
In programming mode the display show only the different types of program with the three LED 2,7
and 9 to each functions. To change the type of programming press shortly the button 20 until your
reach to the right function use according table below. After 10 seconds the COMPACT exit the
programming mode and load the new change.
In user mode, the disabled functions are displayed by blinking LED. So you can see in witch mode
is disabled.
