remarks
E33-01 Unsymmetrical bus voltage
The difference between the bus voltages
of the power modules 1 and 2 is >60V.
-check power modules
-
check the flat ribbon cable between
MAPRO and DRV
-check connector X17 on DRV
E33-02 Unsymmetrical bus voltage Startup
The difference between the bus voltages
of the power modules 1 and 2 is >60V at
startup.
E34-00 Fan current
The current consumption of the fans is
too high.
-check fans and their wiring
E41-01 Mains loss
The primary DSP couldn’t detect a mains
supply.
-check mains supply
-check wiring between NEFI and DRV
(X14)
E48-00 End of Demo mode
The maximum test time of the demonstra
-
tion mode has ended.
Restart the machine
Lines in display “= = =”
CAN bus connection between front panel
and MAPRO is jammed.
-Check CAN bus connection/wires
-measure the CAN bus (see page 61)
-replace MAPRO and/or front panel if
necessary
