CHECK
• The machine should be driven at limited speed in
ramps.
• Check the Personality : Drive, Max and adjust if nec-
essary.

• Check the Personality : Drive, Max and adjust if nec-
essary.
CHECK
• Check the Can Bus connections on the Master con-
troller : CR2(27) & CR2(28).
• Disconnect CR3 (Slave controller connector) and
measure resistance between CR3(27) and
CR3(28). If it is not 60  ±5%, check continuity of
the bus wires :
-CR2(27) to CR3(27) & CR2(28) to CR3(28);
-CR2(27) to CR1(29) & CR2(28) to CR1(18);
-ground panel board : CR1(29) to CR1(17) &
CR1(18) to CR1(6);
-CR1(6) to CR25(A) & CR1(17) to CR25(B);
-CR25(A) to CR4(P) & CR25(B) to CR4(N);
-Platform console : CR4(P) to J1(3) & CR4(N) to
J1(4).
• Ensure that all the connectors pins are properly in
place and the connectors are free of moisture or
oxidation.
• Measure the resistance between J1(3) and J1(4) of
the platform board : if it is not 120  ±5%, replace
the board.
• Check the Can Bus connections on the Slave con-
troller : CR3(27) & CR3(28).
