operating condition.
5.4.3 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, you must then 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 disabling the Auxiliary Contact. Programmed
like this the Auxiliary Contact works with the lowest set condition and stops when it
has reached the highest programmed condition through charging.
Example: start of a generator with the XP-COMPACT
In order to program the auxiliary contact to start at 25% and to stop at 75% of the
battery state-of-charge, here is the procedure to follow:
− Press the key AUX. CONTACT (Program) 21 during at least 2 seconds. Then
the states will be displayed blinking (factory settings LED’s 10/11/12/13). As
these states are not wished for the start of the generator, they must be disabled.
− With the key (select) 20, select the LED’s to disable (the active LED’s are
blinking) and disable them with the key 19 Change Status. Select the other
LED’s to switch off with the key (select) 20 and switch them off with the key 19
Change Status until all are disabled.
− Then select the LED 17 with the key (select) 20 and activate the contact with the
key 19 Change Status. The generator will start once the LED 17 switches of.
− Then select the LED 16 with the key (select) 20 and activate the contact with the
key 19 Change Status. The generator will stop once the LED 16 switches on.
− If no key is activated during 30 seconds, the normal operation states are
displayed automatically again.
For a control the key Program can be pressed at least 2 seconds. The values set are
displayed blinking.
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.
4.6.4). 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).
5.4.4 Auxiliary Contact as Twilight Witch (with solar charger option)
The Auxiliary Contact of the XP-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 XP-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 XP-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.
