LED ”Battery fault
– Battery voltage < 23 V
– Open line to battery or fuse F501 / F502 blown
– Autom. test to indicate battery presence negative
– Autom. battery load test negative
LED ”Power supply fault
– Input voltage > 31.0 V –> power unit malfunction
– EEPROM check sum error
LED ”Power on”
– Input voltage > 28.5 V
c) Operation with
external voltage (in-
stead of battery)
LED ”Battery fault
– Battery voltage or external voltage < 23 V or > 31.0 V
– Autom. presence test (external voltage) negative or fuse F501 / F502
blown
LED ”Power supply fault
– Input voltage > 31.0 V –> power unit malfunction
– EEPROM check sum error
LED ”Power on”
– Input voltage > 28.5 V
d) Operation without
battery or external
voltage
LED ”Battery fault
– no function
6 Key "S1": System start only with battery (without mains voltage)
7 Plug-in terminals "K1": Supply for the modules "I-Bus"
