3A SAFETY OUTPUT
Condition for error detection
Logic stop.
Verify:
- Traction logic unit alarms.
• If YES, the alarm it is only a consequence. Check the diagnostics of the lifting logic unit
• If NO, Check the LV wiring harness and the connection between pin 11 connector JT and pin19
connector JP
• If NO, that the pin 19, connector JP, cable LV is a GND
• If NO, internal fault of the logic unit
• Reference wiring diagram page 2/7 (chapter 17, section WIRING DIAGRAMS)
3B SLIP PROFILE
Condition for error detection
Error in the memory data where the flowing parameters are loaded.
Make a logic unit RESET to re-load the default parameters.
• If the error persists when the machine is switched back on, install the last version of the software using
the programmer.
• If the problem presists replace the logic unit.
3C ANALOG INPUT
Condition for error detection
Control internal error.
• check the tuck and motor insulation (INSULATION CONTROL PROCEDURE and MOTOR WINDING
CONTROL PROCEDURE)
• check the connections and wiring harnesses
• check the sensors and potentiometers connected to the logic unit
Replace the logic unit.
3D HARDWARE FAULT
Condition for error detection
Control internal error.
• check the tuck and motor insulation (INSULATION CONTROL PROCEDURE and MOTOR WINDING
CONTROL PROCEDURE)
• check the connections and wiring harnesses
• check the sensors and potentiometers connected to the logic unit
Replace the logic unit.
