The Battery Charger - Studer XP-COMPACT XPC 1400-12 Betriebs- Und Montageanleitung

STUDER Innotec XP-COMPACT
If the Inverter has been overloaded for a long time or it has been working in too high
surrounding temperatures, it will switch off. The LED 10 „Over Temp." is lit and the
LED 13 „OFF" blinks. After cooling down, the inverter switches back on automatically.
One minute before the inverter switches off for too high temperature it gives out an
acoustic alarm signal. If the Auxiliary Contact has been programmed to detect the
high temperature then it synchronizes the relay with the alarm signal. In this way, for
example, an emergency back- up system can be started without any break in the
energy supply.
4.6.4 Battery Condition
Deep discharge of the lead-acid batteries leads to high losses in capacity and early
aging. That is why the battery condition is continuously controlled and supervised.
With low volt-age the inverter switches off. The LED 12 „L/H Batt." is lit and the LED
13 „OFF" blinks. When the battery voltage gets up to 12.1V / 24.2V / 48.4V, the
Inverter switches on automatically. One minute before the Inverter switches off due to
low voltage it gives out an acoustic alarm signal. If the Auxiliary Contact has been
programmed to detect the low voltage then it synchronizes the Aux. Contact with the
alarm signal. In this way, for example, an emergency back up system can be started
without any break in the energy supply.
The low voltage is set to 11.6V / 23.2V / 46.4V. These settings are standard for most
batteries. These voltage levels are maintained by the built-in Battery-Management-
System of the XP-COMPACT by matching the load and the battery condition.
This setting is comparable with the levels of 10.8V/ 21.6V / 43.2 which are given
for most batteries at nominal load.
All voltage levels can be programmed. See the instructions under the section on
Programming. Check with your battery supplier which voltage values should be set.

The battery charger

4.7.1 Cycle of charge
The full automatic XP-COMPACT Battery Charger is adjusted at the factory so that
most lead-acid and lead-gel batteries can be charged to the maximum. As soon as
the minimum alternating voltage for the AC IN set on the Turning Knob 23 is available
at the input (LED 1 AC IN is lit), the Battery Charger is switched on automatically
(LED 2 CHARGER is lit). The battery is fully automatically charged matching to the
charge level, the adjusted volt-age levels and the charge current. Thanks to the built-
in Float Charge System, the batteries can be left connected for unlimited time with
the Battery Charger switched on.
During the charging phase the appliances at the outlet AC OUT are continually
supplied with power (LED 8 AC OUT is lit).
