STUDER INNOTEC XP-COMPACT
XP-COMPACT V5.3 16/77
4.6.1 Charge detection system „Standby“
In order to avoid unnecessary discharge of the battery, the inverter switches OFF
automatically if no appliance is connected and switches ON automatically again if
appliance is connected. The LED 8 blinks if the inverter is in Standby-Mode. The
switching-on/starting level can be adjusted with the turning knob 24 „STANDBY”.
Adjusting the switching-on level is as follows: Switch off all consuming devices, turn
the Turning Knob 24 to the right until the LED 8 is blinking, switch on the smallest
consuming device (i.e. Mobile phone charger), turn the Turning Knob slowly to the
left until LED 8 is lit.
If the Standby-Mode is not wanted, turn the Turning Knob 24 to the left, to the OFF
position.
4.6.2 Overload
If the Inverter is too long or too heavily overloaded, it switches off. The LED 11
„Overload“ is lit and LED 13 „OFF“ blinks. After ca. 10 seconds the Inverter switches
on automatically. If the Inverter is overloaded four times one after another in a short
time, then it no longer switches on automatically. The LED 13 remains lit. Press the
push button 19 „ON/OFF“ in order to switch on the Inverter.
4.6.3 Overheating (Over Temp.)
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.
4.7 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
