SAM poti
•
Check cable
•
Replace SAM
One of the potentiometers are defective.
If one of the two SAM potentiometer differs more than 90° to the SAM encoder
position.
Error X
070
BAM Overload
•
Average brake force is to high
•
Apply correct brake force
•
Check parameter "Overload Time"

EOL
•
End of life is reached
The system was running more than 490000 km or was used longer than 8200h.
Error X
072
Temp
•
Check the temperature of the converter modules
•
Check if there is hot air blown on the converter modules
The controller board or the converter board temperature is higher than 70°C.
Error X
073
EAM Speed to high
•
Adjust speed between Servicemanager and car speed
Speed is higher than 220km/h
Error X
074
EAM No Speed Signal
•
Check Speed sensors or CAN Adapter
No speed signal longer than 10min.
Error X
075
BAM Stroke to big
•
Readjust Brackets
Stroke has to be shorter than 80 mm
Error X
076
EAM Test
•
Charge the backup-battery
•
Set parameter “Minimal drop pulse test [mV]” to zero.
Restart.
If the Error is disappeared, then the Pulse test box is defective
Test of backup-battery failed

Plug
•
Check if board- and backup-battery are connected and charged.
•
There is a wrong converter module connected, Make sure S1 is at
connector X31 & X32 and S2 is at connector X41 & X42
•
Wrong software installed, reinstall the correct software for S1 &
S2
