yellow unused
Indicators vary in meaning according to application:
a) Battery operation
and symmetry moni-
toring
LED ”Power supply fault
– Input voltage > 31.0 V –> power unit malfunction
– Battery voltage > 29.5 V or < 25 V –> charger malfunction
– Charger malfunction
– Charger shut down (via software function)
– Temperature sensor open line / short circuit
– Temperature sensor measures > 55 °C
– EEPROM check sum error
LED ”Power on”
– Input voltage > 28.5 V
LED ”Battery fault
– Battery voltage < 23 V
– Asymmetry > 1.0 V or fuse F503 blown
– Possibly cell short circuit
– Open line to battery or fuse F501 / F502 blown
– Autom. test to indicate battery presence negative
– Autom. battery load test negative
b) Battery operation
without symmetry
monitoring
LED ”Power supply fault
– Input voltage > 31.0 V –> power unit malfunction
– Battery voltage > 29.5V or < 25 V –> charger malfunction
– Charger malfunction
– Charger shut down (via software function)
– Temperature sensor open line / short circuit
– Temperature sensor measures > 55 °C
– EEPROM check sum error
LED ”Power on”
– Input voltage > 28.5 V
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
