System
Robway RCI
Symptom
Load reading shows "0" or "Err"; Audible alarm sounds.
Diagnosis & fix steps
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.
Red Seal field insights
If you see Error 32, the angle sensor has likely "slipped." Robway angle sensors use a pendulum or a gear-driven pot. If the crane hit a bump, the gear might have jumped. You can manually rotate the gear until the display matches a manual inclinometer.
