Error code 271


 

Check the row addressing: Can Enable short-circuit

Warning at Maestro.

Maestro (271-2)

since version 10.12

When does the warning occur?

When checking the row addressing, it was detected that there is a short-circuit between Can Enable (PIN 5 on the 6-pin AMP connector) and the operating voltage in the row bus.

Does a Drilling error (drilling drop-out) occur?

Yes!

What to do?

  • Do NOT address the module again!

  • Check the wiring on the modules.

  • Restart the system.

  • If the error still occurs, contact your HORSCH dealer.


  • Information for trained service staff:

    • If readdressing, the two rows have the address "1".

    • As a result EC-103 "Row module: Dual addressing" is displayed. EC-271 is no longer displayed.

    • EC-266 "Checking the row addressing:: Not enough rows" is then displayed.

    • The actual cause of the error (the short-circuit of CAN Enable) can no longer be diagnosed.


    • Check the wiring (all 6-pin plug-and-socket connections in the row wiring loom).

    • Unplug all row modules.

    • With row 1 "IN" and "OUT" remain separated.

    • From row 2 to x connect the "IN" connector with the "OUT" connector (bridging the row).

    • Measure all connectors of row 1 "OUT" successively, starting with between Pin 1 (0V E) and Pin 5 (Can Enable).

    • (Subitem) Operating voltage may only be present on the "OUT" connector of the wiring loom of the first row between Pin 1 and Pin 5.

    • (Subitem) With all other 6-pin row wiring loom connectors no voltage may be present between Pin 1 and Pin 5 if no connection is made once between row 1 "OUT" and the measured row "IN" or "OUT".

    • Check the modules => Plug in all rows again. Disconnect the row 1 "IN" connector. All "OUT" or "IN" connectors of rows 2 to x must have 0 V between Pin 1 and Pin 5.

    • Replace modules defined as faulty.


    • Restart the system.


    • Inspect system for correct cabling and BUS error.

After what time is the warning repeated?

0 sec.

Is there an audible indication?

single audible signal

How is the warning confirmed?

not possible until error has been rectified
