- Error codes and alarm signals. 

 

3.4.1

 

- 02 - Hardware lockup. 

Power source lockup due to software error. Replace the control board (38). 
 

3.4.2

 

- 06 - Communication error on CAN bus. 

Communication error between control board (38) and panel board (20) on Gas Console, 

detected by Master control on control board (38). Perform the tests indicated in case of failure of 
the CAN BUS COMMUNICATION TEST in par. 3.3.3. 

 

3.4.3

 

- 07 - “rob” “int” flashing on displays (B) (C) of the Power Source and (F) (M) on 
Gas Console. Operating permission from system (interlock). 

This alarm indicates that the “interlock” signal originating from the system (pantograph or 

robot) needed to operate the Power Source is missing. The interlock signal may also be 
interpreted as “pantograph or robot connected” to the Power Source. 

 

OPERATING PERMISSION FROM SYSTEM TEST. 

Correct? 

‰

 

Remote board (59), connector J2, terminals 3(+) and 11(-) = 0 Vdc, (contact closed) operating 

permission present, +24 Vdc (contact open) operating permission missing. 

 
 YES 
 
 NO 

 

Check the wiring between connector (4) of the Power Source and the actuator of 
the signal to allows system operation (pantograph or robot). 

 

Check the wiring between J2 remote board (59) and connector (4) on the Power 
Source. 

 

Check the wiring between J3 remote board (59) and J1 control board (38). 

 

Make sure the remote board (59) power supply is correct, performing if necessary 
the REMOTE BOARD (59) POWER SUPPLY TEST in par. 3.3.4. 

 

With Power Source off temporarily disconnect connector J1 on control board (38) 
and check the resistance on terminals 5 and 6 of J1 on control board (38). Correct 
value = diode junction in both measurement directions. If incorrect, replace 
control board (38). 

 

Replace the remote (59) and/or control (38) boards. 

 

Replace the remote (59) and/or control (38) boards. 
 

3.4.4

 

- 09 - Communication error on CAN bus. 

Communication error between control board (38) and panel board (20) on Gas Console, 

detected by Slave control on panel board (20). Perform the tests indicated in case of failure of the 
CAN BUS COMMUNICATION TEST in par. 3.3.3.
