04 OVER-VOLTAGE: value of the DC Bus ex-
ceeds its maximum threshold.
05 SERIAL TIMEOUT: Serial communication
timeout. Communication errors between
the high kit and the low kit.
06 EEPROM: errors in the data stored in Ee-
prom.
07 DC MOTOR ENCODER (gradient motor ) For details, see "6.10 Message on the dis-
08 AC MOTOR ENCODER (belt motor)
Uncontrolled copy if printed
- Brake unit (Broken/not connected)
- Input voltage with power surges.
- Power supply cable not correctly con-
nected.
-Check the serial communication.
-The error may occur in the case of up-
grading the firmware when the new ver-
sion involves a set of parameters that are
different than the previous version. Per-
form a factory reset (802 =1, then 800 =1)
+ standard settings; For details, see "6.5
procedure for restoring the low kit facto-
ry settings"
- If not OK, replace the low kit.

-Check the motor side encoder connector
contacts. They must be "regular" and not
enlarged or stretched out [1 ].
- Check that the power supply box code is
T0001296AC (for DJJ0E*) or T0001203AD
(for DJJ0A*). Check that a secondary fer-
rite [2] is present for the motor encoder
harness, inside the machine. [3] . Check
that the two ferrites are properly closed.
- If it is always present: replace the mo-
tor-encoder group from AA version to the
last version.
