Question 1

What does Other fault code Error 02 mean?

Accepted Answer

Error 02 (Robway RCI): Screen is blank or "flashing"; All crane motions disabled (Motion Cut). Fix: Communications Fault.

LOGIC: The display console in the cab is not receiving data from the main processing unit (the "brain").

ACTION: 1. Check the data cable between the console and the CPU box. 
2. Verify the CPU box has green "heartbeat" LEDs lit.

Question 2

What does Other fault code Error 101 / 301 mean?

Accepted Answer

Error 101 / 301 (Robway RCI): Load stays at a fixed value regardless of weight lifted. Fix: Load Cell / Transducer Offset Error.

LOGIC: The "Zero" point of the sensor has drifted too far from the calibrated value, often due to sensor damage or extreme cold.

ACTION: 1. Check for physical damage to the load cell (links or pins). 
2. Perform a "Zero Calibration" with no load on the hook.

Question 3

What does Other fault code Error 31 / 32 mean?

Accepted Answer

Error 31 / 32 (Robway RCI): Load reading shows "0" or "Err"; Audible alarm sounds. Fix: Sensor Input Out of Range (P1/Angle).

LOGIC: The LMI is seeing a signal from the pressure transducer (31) or angle sensor (32) that is below 4mA or above 20mA.

ACTION: 1. Unplug the sensor and check for 15-24V power on the supply pin. 
2. Measure the signal wire with a multimeter in mA mode.

Question 4

What does Other fault code Error 54 mean?

Accepted Answer

Error 54 (Robway RCI): Winch-up and Telescope-out functions cut off. Fix: ATB (Anti-Two Block) Cable Break.

LOGIC: The safety loop for the boom-tip switch is open (high resistance).

ACTION: 1. Check the reeling drum cable on the side of the boom. 
2. Verify the ATB weight is not tangled.
